Texas Home Affordability Calculator 2026: What Houston Households Can Actually Afford

Texas Home Affordability Calculator 2026: What Houston Households Can Actually Afford

The Number Everyone Gets Wrong First

Most Houston buyers open an online mortgage calculator, type in their income, and feel briefly encouraged. Then they get their first full payment quote and the number looks wrong. It is not wrong. Texas has two structural affordability drags that online calculators routinely underweight: property taxes among the highest in the United States and homeowners insurance premiums that are also the highest in the country. When you add both to a principal-and-interest payment, a home that looked affordable at first glance can easily chew through 32-35% of gross income before you include a single other debt payment.

This guide applies the 28/36 debt-to-income (DTI) rule to real Houston income brackets using actual 2026 rates, Texas property tax data from the Texas Comptroller, and Texas homeowners insurance data from Bankrate's May 2026 analysis. The worked examples below use gross income levels of $80,000, $120,000, $160,000, and $200,000 so you can find your bracket and build a realistic budget before you ever speak to a lender.

TL;DR: A Houston household earning the metro-area median of roughly $74,000 can qualify for approximately $220,000-$250,000 in purchasing power under the strict 28% front-end rule at a 6.4% rate with 5% down, once Texas property taxes (~2.4% effective in Harris County) and insurance (~$5,300 per year on a $300,000 home in Houston per Bankrate 2026) are folded into PITI. The old "$100K income = $300K home" rule of thumb that circulated widely before 2022 is no longer a reliable benchmark in Texas.

Understanding the 28/36 DTI Rule in Texas Context

The 28/36 rule is a mortgage underwriting guideline used by conventional lenders (Fannie Mae, Freddie Mac) and most FHA lenders. It says that your monthly housing costs should not exceed 28% of your gross monthly income (the "front-end" or "housing" ratio), and your total monthly debt obligations including housing should not exceed 36% of gross monthly income (the "back-end" or "total debt" ratio). Some lenders allow conventional loans to stretch to 43-45% back-end DTI with compensating factors such as strong reserves or high credit scores, and FHA guidelines technically permit up to 50% back-end with compensating factors, but 28/36 is the conservative planning standard that leaves room for life.

PITI is the acronym for principal, interest, taxes, and insurance. For conventional lending purposes, PITI is the front-end housing payment. It includes:

• Principal and interest (P&I): The amortized payment on the loan itself
• Property taxes (T): Escrowed monthly, based on the county appraisal district's assessed value times the combined tax rate
• Homeowners insurance (I): Escrowed monthly; in Houston this is the most expensive metro insurance market in the country according to NerdWallet's 2026 city rankings
• PMI (private mortgage insurance): Required on conventional loans with less than 20% down; not technically part of the PITI acronym but always included in the front-end DTI calculation by lenders
• MIP (mortgage insurance premium): The FHA equivalent of PMI; includes both an upfront premium (1.75% of the loan, usually financed) and an annual premium billed monthly

The back-end DTI adds all other recurring monthly debt: auto loans, student loans, minimum credit card payments, personal loans, and any co-signed obligations. It does not include utilities, groceries, or subscriptions.

Why Texas Affordability Is Worse Than the Headline Income Suggests

Texas has no state income tax, which sounds like a significant affordability advantage. In many states that comparison holds. But Texas makes up for the absence of income tax with property taxes that, on a per-dollar-of-home-value basis, rank among the highest in the country. The effective property tax rate in Texas averages around 1.6-1.8% statewide, and in Harris County (Houston) the combined rate for a typical homeowner in an unincorporated area often falls in the 2.2-2.6% range depending on the school district and municipal utility district (MUD) tax overlay. Harris County itself sets its rate, but the sum of school district rates (typically 0.95-1.10% alone), county, city or MUD, and flood control district rates stack quickly.

According to SmartAsset's Texas property tax data, the effective property tax rate in Harris County is approximately 1.46% at the county level alone, but that figure does not include school district and special district rates. A typical total effective rate for a Spring, TX home in Klein ISD, for example, runs closer to 2.3-2.5% of appraised value per year.

Texas homeowners insurance is the second structural drag. Bankrate's May 2026 analysis found that the average annual homeowners insurance premium in Houston is $5,300 for a home with $300,000 in dwelling coverage, which is 119% above the national average and the highest of any major U.S. city they tracked. The Texas Department of Insurance (TDI) reports that statewide homeowners rates increased 21.1% in 2023 and an additional 18.7% in 2024 before moderating to 4.3% in 2025. The compounding effect of those back-to-back increases means Houston homeowners are paying materially more in 2026 than they were in 2021, even before accounting for rising home values.

Together, these two factors explain why Texas affordability benchmarks can look worse than other no-income-tax states. A buyer in Nevada or Florida with the same income and the same purchase price will typically have a lower monthly PITI because their property tax and insurance burdens are lower.

Current Rate Environment: What 2026 Rates Are Used in These Examples

As of late May 2026, NerdWallet's daily rate tracker shows the national average 30-year fixed rate at approximately 6.42% for conventional and 5.38% for FHA (note that FHA and conventional rates diverge meaningfully in the current environment). Bankrate's lender survey shows the 30-year conventional rate at 6.65% as of May 25, 2026.

For the worked examples below, this guide uses: - Conventional 30-year rate: 6.5% (a round number in the middle of the current range, conservative for planning) - FHA 30-year rate: 5.75% (FHA rates are running well below conventional in 2026) - Harris County effective property tax rate: 2.4% (total combined rate for a typical Spring or Katy address; verify at HCAD for your specific parcel) - Homeowners insurance: 1.77% of purchase price per year (derived from Bankrate's $5,300/yr on $300K home figure; scales with value)

FHA vs. Conventional: The Two Paths Under 20% Down

For buyers without 20% down, the choice between FHA and conventional loan structures is central to the affordability math.

FHA (Federal Housing Administration) loans in Harris County 2026: - Minimum down payment: 3.5% for borrowers with 580+ FICO; 10% for 500-579 FICO - 2026 FHA loan limit for Harris County: $541,287 for a single-family home (per HUD's 2026 loan limit announcement) - Upfront mortgage insurance premium (UFMIP): 1.75% of the base loan amount, typically financed into the loan - Annual MIP: 0.55% of the loan balance per year for loans with 10%+ down; 0.55% for 30-year loans with less than 10% down and loan amounts under $150K, scaling to 0.80-0.85% for higher balances. MIP now stays for the life of the loan on most FHA loans (unless the original down payment was 10% or more, in which case MIP drops at 11 years) - FHA rates are currently running approximately 0.75-1.0% below conventional in 2026

Conventional loans: - Minimum down payment: 3% with some programs; 5% is standard for most borrowers - PMI required until 80% loan-to-value; automatic termination at 78% LTV under the Homeowners Protection Act - PMI cost: typically 0.5-1.15% of the loan balance annually depending on credit score, LTV ratio, and loan term - No FHA limit restrictions; conforming cap is $832,750 for all Texas counties (no high-balance counties in Texas) - PMI cancels when equity reaches 80%; FHA MIP does not on most recent originations

Which is cheaper month to month? Despite the higher rate, conventional with 5% down often produces a lower monthly payment than FHA with 3.5% down for buyers with 700+ FICO scores, because FHA MIP at 0.55-0.85% per year on the full base loan balance adds meaningfully to the monthly payment. At a 680 FICO, the calculation can tip toward FHA. Run both scenarios with your lender.

Worked Examples: Four Houston Income Brackets

All examples below assume: - Harris County effective tax rate: 2.4% per year of purchase price (conservative; actual rate depends on ISD and MUD) - Homeowners insurance: $5,300/yr on a $300K home, scaling proportionally (approximately $442/month on $300K) - Conventional: 30-year fixed at 6.5%, 5% down, PMI at 0.7% annually - FHA: 30-year fixed at 5.75%, 3.5% down, MIP at 0.55% annually (plus UFMIP financed) - The 28% front-end cap is applied to gross monthly income

Worked Example: $80,000 Gross Annual Income

Gross monthly income: $6,667
28% front-end cap (max PITI): $1,867 per month
36% back-end cap (max total debt): $2,400 per month

Scenario A: Conventional, 5% down, $6.5% rate

Target purchase price: $250,000
Loan amount: $237,500 (95% of $250,000)
P&I at 6.5%: $1,501/month
Property taxes: $500/month ($250,000 x 2.4% / 12)
Homeowners insurance: $368/month ($250,000 x 1.77% / 12)
PMI: $138/month ($237,500 x 0.7% / 12)
Total PITI + PMI: $2,507/month (37.6% of gross income -- this FAILS the 28% front-end test)

The math shows that a $250,000 purchase with conventional 5% down exceeds the 28% front-end limit for an $80,000 income buyer. Reducing the target price is necessary.

Recalculate at $200,000:
Loan: $190,000; P&I: $1,201; Taxes: $400; Insurance: $295; PMI: $111
Total: $2,007 (30.1% -- still above 28%)

Recalculate at $170,000:
Loan: $161,500; P&I: $1,021; Taxes: $340; Insurance: $250; PMI: $94
Total: $1,705 (25.6% -- within 28% front-end; leaves $695/month for other debt)

At $80,000 gross income in Harris County in 2026, a realistic conventional purchase with 5% down lands between $150,000-$175,000 under strict 28% front-end discipline. FHA at 3.5% and 5.75% rate provides slightly more room (roughly $185,000-$200,000) because the lower rate offsets the MIP burden.

The $80K income range is essentially priced out of most Harris County single-family inventory without down payment assistance or a co-borrower. Review Texas Down Payment Assistance programs and Texas First-Time Home Buyer grants for subsidy options that can bridge the gap.

Worked Example: $120,000 Gross Annual Income

Gross monthly income: $10,000
28% front-end cap: $2,800 per month
36% back-end cap: $3,600 per month

Scenario A: Conventional, 5% down, 6.5% rate, $350,000 purchase

Loan: $332,500; P&I: $2,101; Taxes: $700; Insurance: $515; PMI: $194
Total: $3,510 (35.1% -- exceeds 28% front-end significantly)

Scenario B: Conventional, 5% down, 6.5% rate, $280,000 purchase

Loan: $266,000; P&I: $1,681; Taxes: $560; Insurance: $412; PMI: $155
Total: $2,808 (28.1% -- essentially at the limit)

Scenario C: 20% down, no PMI, $350,000 purchase

Loan: $280,000; P&I: $1,770; Taxes: $700; Insurance: $515; PMI: $0
Total: $2,985 (29.9% -- still above 28% front-end, though some lenders allow to 30% with strong credit)

The $120,000 income buyer with 5% conventional can reasonably target approximately $275,000-$300,000. With 20% down, the purchase power stretches closer to $340,000-$355,000 while staying at or near 28%. If the household carries $400-$500/month in auto or student loan payments, the back-end constraint kicks in before the front-end for purchases above $290,000.

Worked Example: $160,000 Gross Annual Income

Gross monthly income: $13,333
28% front-end cap: $3,733 per month
36% back-end cap: $4,800 per month

Scenario A: Conventional, 5% down, 6.5% rate, $475,000 purchase

Loan: $451,250; P&I: $2,852; Taxes: $950; Insurance: $699; PMI: $263
Total: $4,764 (35.7% -- exceeds 28% front-end by wide margin)

Scenario B: Conventional, 5% down, 6.5% rate, $380,000 purchase

Loan: $361,000; P&I: $2,282; Taxes: $760; Insurance: $559; PMI: $211
Total: $3,812 (28.6% -- at limit with minor stretch)

Scenario C: 20% down, no PMI, $475,000 purchase

Loan: $380,000; P&I: $2,402; Taxes: $950; Insurance: $699; PMI: $0
Total: $4,051 (30.4% -- slightly above strict 28%; within range most lenders approve at 700+ FICO)

Scenario D: 20% down, $400,000 purchase

Loan: $320,000; P&I: $2,023; Taxes: $800; Insurance: $589; PMI: $0
Total: $3,412 (25.6% -- comfortably within 28%, leaves room for back-end debt)

The $160,000 income household can realistically target $375,000-$425,000 with 5% down staying near the 28% front-end limit. With 20% down, the ceiling moves to approximately $450,000-$470,000. This is the income range that gains the most ground by making the larger down payment, because eliminating PMI ($200-$260/month at this price range) meaningfully extends purchase power.

Worked Example: $200,000 Gross Annual Income

Gross monthly income: $16,667
28% front-end cap: $4,667 per month
36% back-end cap: $6,000 per month

Scenario A: Conventional, 5% down, 6.5% rate, $525,000 purchase

Loan: $498,750; P&I: $3,152; Taxes: $1,050; Insurance: $773; PMI: $291
Total: $5,266 (31.6% -- above 28% front-end)

Scenario B: Conventional, 5% down, 6.5% rate, $475,000 purchase

Loan: $451,250; P&I: $2,852; Taxes: $950; Insurance: $699; PMI: $263
Total: $4,764 (28.6% -- essentially at limit)

Scenario C: 20% down, no PMI, $575,000 purchase

Loan: $460,000; P&I: $2,908; Taxes: $1,150; Insurance: $847; PMI: $0
Total: $4,905 (29.4% -- slightly above 28%, likely approved at prime credit)

Scenario D: 20% down, $525,000 purchase

Loan: $420,000; P&I: $2,655; Taxes: $1,050; Insurance: $773; PMI: $0
Total: $4,478 (26.9% -- under 28%, well within guidelines)

The $200,000 income household can purchase in the $470,000-$540,000 range with 5% conventional down, or push to $520,000-$580,000 with 20% down and strong reserves. At this income level, the back-end DTI becomes the binding constraint if the household carries $800-$1,200 per month in other debt (two car payments, student loans), which would limit total PITI to approximately $3,600-$4,000 to stay under the 36% back-end cap.

For households at this income range considering whether to lock a rate now or wait, the Texas Mortgage Rate Lock guide at harbertgroup.com covers the timing and cost of rate lock extensions.

The PMI Threshold and When to Consider a Larger Down Payment

PMI on conventional loans is required when the loan-to-value ratio (LTV) exceeds 80% at origination. That means a 20% down payment eliminates PMI entirely. For buyers who can reach 20%, the monthly savings are real:

There is also a middle path: putting 10% down reduces the LTV to 90%, which lowers PMI rates (typically to 0.4-0.6% depending on credit score) and builds equity faster. A buyer who can reach 10% but not 20% should run the numbers on both scenarios. Texas Down Payment Assistance programs from agencies including the Texas State Affordable Housing Corporation (TSAHC) can help qualified buyers reach 5% or more without depleting savings.

Note that FHA MIP behaves differently. Under current FHA rules, MIP on a 30-year loan with less than 10% down does not cancel; it lasts the life of the loan. For a buyer who plans to hold the home for 10 or more years, refinancing into a conventional loan once equity exceeds 20% is the standard exit from FHA MIP.

The "$100K = $300K Home" Rule That Broke After 2022

For years, a popular rule of thumb circulated in real estate: earn $100,000, you can buy a $300,000 home. The ratio (3x income) was a rough approximation calibrated to an environment where 30-year rates were 3-4%, property taxes were lower, and insurance was more affordable. In Houston in 2026, that rule does not hold for most buyers.

Here is why the math has shifted:

At 3.5% rate (2021 environment), $300,000 purchase, 5% down:
P&I: $1,283; Taxes: $600; Insurance: $295 (insurance was lower then); PMI: $166
Total PITI: $2,344 = 28.1% of $100,000 gross (28% limit: $2,333) -- barely inside the limit

At 6.5% rate (2026), same $300,000 purchase, 5% down:
P&I: $1,801; Taxes: $600; Insurance: $442 (current Houston avg for $300K); PMI: $166
Total PITI: $3,009 = 36.1% of $100,000 gross -- significantly above the 28% front-end limit

The rate increase alone added roughly $518/month to the principal-and-interest payment on a $285,000 loan. Insurance increases from 2022-2025 added another $100-$150/month in Houston. Together, the same $100,000 income that could comfortably reach a $300,000 home in 2021 can now realistically reach $200,000-$225,000 under strict 28% front-end discipline in 2026.

Some lenders will approve up to 43-45% back-end DTI with strong credit and reserves, which stretches purchase power. But stretching DTI significantly above 28% front-end in Texas creates real cash-flow risk, because the property tax and insurance payments are not discretionary.

Summary Affordability Table: Income to Purchase Price in Houston 2026

The following table summarizes the approximate maximum purchase price for each income bracket, assuming conventional 5% down at 6.5%, Harris County effective tax rate of 2.4%, and Houston insurance costs, targeting a 28% front-end DTI:

These figures are conservative estimates for planning. Actual qualification may vary based on credit score, existing debt load, lender overlays, and the specific tax rate for the parcel. For households in the $74,000 median income range looking for homes in the $200,000-$275,000 range, the Best Houston Suburbs Under $300K guide at harbertgroup.com maps out where inventory exists in that price band.

How to Apply These Numbers to Your Search

Step 1: Confirm your actual gross monthly income. Use base salary only; bonus and commission income is typically averaged over 24 months and verified with tax returns by lenders.

Step 2: Pull your credit report. Credit scores below 740 increase conventional PMI costs. Scores below 620 typically require FHA. Know your number before you start.

Step 3: List every monthly debt payment. Auto loans, student loans, minimum credit card payments (not balances, but minimum monthly payments), personal loans, co-signed obligations. This total determines your back-end DTI ceiling.

Step 4: Subtract back-end debt from your 36% limit. The remainder is the maximum monthly PITI your back-end DTI allows. Compare this to the 28% front-end limit and take the lower of the two.

Step 5: Look up the actual combined tax rate for the suburb you are targeting. The 2.4% figure used in this guide is a reasonable Harris County average, but rates vary by school district and MUD. Klein ISD properties run around 2.3%; Cypress-Fairbanks ISD properties vary; Fort Bend County properties in Sugar Land typically have a combined rate in the 2.0-2.4% range. Ask your agent or check the property's tax certificate.

Step 6: Get a pre-approval, not just a pre-qualification. A pre-approval involves a hard credit pull and income verification, which produces a reliable ceiling. A pre-qualification is a conversation. For buyers in a competitive market, sellers treat pre-approval as the baseline. See the Texas Pre-Approval vs. Pre-Qualification guide at harbertgroup.com for what documents you need.

Step 7: If the maximum purchase price puts you below your target neighborhood, investigate down payment assistance. TSAHC, the Texas Department of Housing and Community Affairs (TDHCA), and Harris County's own housing programs all offer first-generation and income-qualified assistance. The Texas First-Time Home Buyer resource at harbertgroup.com summarizes the current program landscape.

Frequently Asked Questions

What is the Houston-area median household income used in these calculations?

The Houston-The Woodlands-Sugar Land MSA median household income is approximately $74,000-$77,000 based on 2023 American Community Survey (ACS) five-year estimates released in late 2024. The City of Houston proper runs lower (around $62,894 per the City of Houston's 2023 ACS data), but suburban households in Fort Bend, Montgomery, and parts of Harris County skew higher. For planning purposes, the $74,000 MSA median is a reasonable baseline; individual household situations will differ.

Can FHA loans really save money in Houston despite the MIP?

For buyers with 680-720 FICO scores and limited down payment funds, FHA frequently produces a lower monthly payment in 2026 because FHA rates are running roughly 0.75-1.0% below conventional rates (5.38-5.75% vs. 6.5-6.65% as of May 2026 per NerdWallet and Bankrate). That rate advantage can more than offset the FHA MIP cost for the first several years of ownership. The long-term downside is that FHA MIP on post-2013 loans does not cancel automatically; plan on refinancing into conventional once you have 20% equity, or budget the MIP as a long-term cost.

How do MUD tax rates affect affordability in specific Houston suburbs?

Municipal Utility District (MUD) taxes are special-purpose district taxes that fund water, sewer, and drainage infrastructure in newer master-planned communities. They appear as a separate line item on the tax certificate and add to the total effective rate. A home in a MUD community in Katy or Cypress might have a combined total rate of 2.6-3.0% including the MUD rate, versus 2.0-2.2% for an older neighborhood in the same county without a MUD overlay. Always request the full tax certificate on any home you make an offer on; the MUD rate is not always visible in third-party tax data. See the Houston No-MUD-Tax Suburbs guide at harbertgroup.com for suburbs where MUD taxes do not apply.

Why does the "$100K income = $300K home" rule no longer work in Texas?

At a 3.5% 30-year rate (typical in 2021), a $285,000 loan produced a P&I of $1,280/month. At 6.5%, the same loan produces $1,801/month, an increase of $521/month. On top of that, Houston homeowners insurance has risen roughly 40-45% cumulatively from 2022-2025 per TDI rate change data. The combined effect means the same household income that could comfortably finance $300,000 in 2021 is realistically limited to $200,000-$225,000 in 2026 under conservative 28% front-end DTI discipline. A higher income, a larger down payment, or negotiated seller concessions toward a rate buy-down are the practical paths to reach the $280,000-$320,000 range on a $100,000 income today.

What happens if my back-end DTI is the binding constraint rather than the front-end?

If your total monthly debt obligations (auto loans, student loans, credit cards) already consume a significant portion of your income, the 36% back-end cap will kick in before the 28% front-end. For example, a buyer earning $10,000/month with $1,200/month in car and student loan payments has a back-end cap of $3,600 minus $1,200 = $2,400 left for housing. Their front-end cap is $2,800. The lower figure ($2,400) is the real ceiling. Paying down or paying off an auto loan before applying can meaningfully increase housing budget; each $400/month reduction in recurring debt frees up roughly $30,000-$40,000 in additional purchase power.

How does Texas compare to other states on total housing cost burden?

Despite the no-income-tax benefit, Texas ranks poorly on affordability-adjusted housing cost when property taxes and insurance are included. A buyer in Nevada (no income tax, lower property taxes around 0.5-0.7% effective, lower insurance) can afford roughly 15-20% more home on the same gross income than a Harris County buyer in 2026. A buyer in Florida (no income tax, property tax around 0.9% effective statewide but higher in some counties, also high insurance) fares similarly to Texas. The no-income-tax advantage is real when you rent; it is partially offset when you own in a high-property-tax, high-insurance state like Texas.
