Quick Answer: To afford a $300,000 home in Texas, with current interest rates, you will need an income of approximately $86,000, with a 10% down payment and assuming you have no other monthly debt. Include $500 in monthly debt payments and you will need approximately another $17,000 in income.
Introduction
Unfortunately, most answers you come across online are incorrect, as most sites calculate payment as principal, interest, taxes and insurance and not a state average. Property taxes in Texas, average 1.40% of home value, and insuring a $300,000 house runs about $3,875 a year. When added up and a national calculator will lowball the income you need..
One thing to settle first. Type "income needed for 300k mortgage" into Google and the top results split, because the phrase can mean a $300,000 loan or a $300,000 house. SoFi answers the loan question; Redfin, Rocket Mortgage, and everyone else answer the house question. We answer both and identify which is which.
How much income do you need for a $300k house?
Around $86,400 a year, before taxes. Getting to that number takes two steps, and the first one is understanding what a lender is actually measuring.
Your debt-to-income (DTI) ratio is the lender calculating how much of your gross monthly income is paid to creditor's listed on credit report. You will see the 28/36 rule quoted everywhere: monthly housing costs under 28% of gross income, total debt payments under 36%. Most lenders' underwriting is open to slightly higher. Fannie Mae's automated underwriting system will approve, on conventional loans, all the way to 50% DTI, and FHA can potentially go higher when the loan application has strong compensating factors. We use 36% as the "comfortable" line and 45% as the practical "maximum" limit.
So take a $300,000 sales price with 10% down, which calculates to a $270,000 loan amount. At average rate of 6.95%, the base loan payment is $1,787 a month, but that is the whole bill or this would be a much shorter article. Property taxes, homeowner's insurance, and private mortgage insurance push the full monthly mortgage payment to approximately $2,591 and could increase depending in property has to pay an HOA. Hold that at the 36% DTI line and you need roughly $86,400 a year in gross income, assuming you have no additional debt on your credit report. (Interest rates quoted here are national survey averages, not a quote or an offer; your rate and APR depend on your credit score, loan type, and any origination points.)
Assuming no other existing debts and almost nobody has zero. Add an additional $500 car payment on top and the required income increases to about $103,000, therefore two households earning the same salary receive different pre-approvals. To see how much house your own income supports, run your numbers in our home affordability calculator, or check your ratio first with the DTI calculator.
Asking about a $300,000 loan amount instead of a $300,000 house? Same equation, larger numbers: the income needed for a 300k loan amount is approximately $95,000 a year, payment around $2,843 with Texas taxes and insurance.
What's the monthly payment on a $300k house?
Somewhere between $2,262 and $2,740 in Texas at current interest rates, depending on amount of down payment. The table breaks reflects a breakdown of every factor associated with a full Principal, Interest, Taxes and Insurance payment (PITI). If those figures look high next to numbers you have seen elsewhere, there is a reason. Rocket Mortgage and Zillow both publish payment tables which excludes taxes and insurance entirely and on a Texas home those two expenses run close to $700 a month.
| Down payment | Loan amount | Principal + interest | Property taxes | Insurance | PMI | Total monthly payment | Income needed (36%) |
|---|---|---|---|---|---|---|---|
| 3% ($9,000) | $291,000 | $1,926 | $350 | $323 | $141 | $2,740 | $91,300 |
| 5% ($15,000) | $285,000 | $1,887 | $350 | $323 | $138 | $2,697 | $89,900 |
| 10% ($30,000) | $270,000 | $1,787 | $350 | $323 | $130 | $2,591 | $86,400 |
| 20% ($60,000) | $240,000 | $1,589 | $350 | $323 | $0 | $2,262 | $75,400 |
Assumptions: 30-year fixed at 6.95% (Freddie Mac PMMS Sept 17, 2026), 1.40% Texas average property tax rate (Tax Foundation), $3,875 annual insurance (NerdWallet), PMI at $58 per $100,000 borrowed per year (middle of Freddie Mac's PMI range), with no HOA fees. Larger down payment reduces both the loan amount and the Private Mortgage Insurance amount.
The escrows amounts/charges don't change regardless of what you put down, your lender collects them every month through an escrow account in most cases. So, when a national article quotes you $1,589 a month at 20% down, that is the principal and interest loan payment, not the total payment (PITI). No Texan writes a check that small for a $300,000 house.
Can you afford it on a $50k, $70k, or $100k salary?
Short version: $70,000 is where a $300,000 house starts being possible in Texas. To afford a $300,000 house comfortably, plan on $86,000 and up. Here is how much house each salary supports at today's interest rates with a 10% down payment.
| Annual salary | Comfortable max price (36% DTI, no debts) | Stretch max price (45% DTI, no debts) | Comfortable max with $500/mo debts |
|---|---|---|---|
| $50,000 | $156,000 | $205,000 | $90,000 |
| $60,000 | $195,000 | $255,000 | $129,000 |
| $70,000 | $235,000 | $305,000 | $169,000 |
| $80,000 | $275,000 | $354,000 | $209,000 |
| $100,000 | $354,000 | $453,000 | $288,000 |
Review that third column again. Debt eats buying power faster than income builds it: every $500 a month in payments wipes out approximately $66,000 of a home's purchase price at these interest rates. Most buyers fixate on the down payment and ignore this, as it is usually the easier problem to alleviate.
The key factors that move the number
Four key factors decide the income needed, and two of them you can change inside of 90 days.
Debt-to-income ratio
The one lenders care about most. Your DTI counts the minimum monthly debt payments on car loans, student loans, and credit card balances (anything reported to the three major credit reporting agencies; Equifax, Experian or Transunion), plus the new house payment (PITI), against your calculated gross monthly income. It does not count utilities, groceries, or any monthly bill that doesn't report to credit. Before you apply, it is often worth paying off a specific debt to qualify rather than providing a larger down payment. Say you have a card with an $800 balance and a $200 minimum payment: that one line item costs you $26,000 in buying power, while clearing it costs $800!
Mortgage rates
Mortgage rates reprice weekly, sometime more often and income requirements will move with them: every half-point move in interest rates swings the income needed by about $3,000 a year. We regularly see quarter-point spreads between wholesale lenders on the same credit profile, which is why we broker across multiple lenders instead of using just one rate sheet. Compare loan terms on your own numbers with our mortgage calculator before believing any single quote.
Credit score
Strong credit pays twice here: it lowers your rate and your mortgage insurance down at the same time. A 760-credit score pays roughly a third of the PMI costs (Urban Institute data) that a low-600s score would be required, which on this example is the difference between about $104 and $338 per month on a monthly mortgage insurance. If your credit score is 660 and you can get to a 700 in six months, waiting can raise your buying power more significantly than a pay raise.
Property taxes and homeowners insurance
The two most important housing costs most national calculators get wrong in Texas. Underwriting includes both in your DTI at the county's real tax rate and whatever your provided insurance quote says, so an affordability answer built on low-tax-state assumptions will not survive a Texas pre-approval. Making shopping home insurance quotes before you apply huge in this process, since a cheaper premium provides more buying power, similar to a smaller car payment does.

How loan type changes the income you need
Compared belwo is same house, three of the most common home loan programs and the income requirements vary minimally. Separating factor is the cash you bring to closing.
| Loan type | Cash down | Monthly payment (PITI) | Income needed (36%) |
|---|---|---|---|
| Conventional, 5% down | $15,000 | $2,697 | $89,900 |
| FHA, 3.5% down | $10,500 | $2,758 | $91,900 |
| VA, 0% down | $0 | $2,701 | $90,000 |
The VA loan surprise
A VA loan with no down payment requires about the same income to qualify as conventional loans with $15,000 down. The funding fee (2.15% on first use, per the VA schedule) gets financed and mortgage insurance disappears. If served your country and you are eligible for a VA loan, use it!
FHA loans: lowest cash in, higher monthly payment
FHA loans carry the smallest cash requirement of the three but carries the largest payment, because FHA mortgage insurance runs an annual Mortgage Insurance Premium of 0.55% under HUD's current guideline. Plus an upfront premium that gets financed into the loan amount, which doesn't cancel at 20% equity the way Private Mortgage Insurance. FHA is suggested for buyers whose credit score or DTI will not qualify under conventional underwriting; the Texas FHA requirements allow scores down to 580 with a 3.5% down payment. USDA loans, are also an option, offering another zero-down path in eligible rural areas, including large areas of the counties around San Antonio; USDA loans also carry household income maximum caps. So be sure check both, location and income eligibility.
We run all three loan options on most files under $350,000, because different loans are more advantageous for different borrowers.
How a larger down payment reduces the income you need
Going from a 3% to a 20% down payment reduces the income required by approximately $16,000 a year. Which appears to be a significant factor until you notice the price: an extra $51,000 in cash up front. If qualifying is your problem, that is an expensive fix. Paying off a $500 monthly debt does more and typically costs less.
Where the larger down payment make a impact is the 20% down payment, where private mortgage insurance drops off and you get a lower monthly payment by nearly $500 and in a competitive offer. We don't recommend you drain your savings to get there: you still need cash for closing costs, which run 2% to 5% of the purchase price plus prepaids, and lenders prefer to see cash reserves that cover a few months of housing costs. The minimum down payment on conventional loans is 3% for first-time buyers, and taking it is often the right call; lender credits can offset part of the closing costs in exchange for a modestly higher rate.
What a $300k budget buys in San Antonio
The San Antonio metro median sale price sat just above $299,000 in August 2026 and with close to six months of inventory sitting on the market. Buyers at that price have room to negotiate, that they have not had in a while.
Two local things to know. Bexar County's effective property tax rate sits a touch above the state average. Reference your specific district with our Texas property tax calculator. The homestead exemption, which the state raised to $140,000 of school-district value after voters approved Proposition 13 in November of 2025. Claim it and the school district taxes your $300,000 home as though it were worth $160,000, which is why your first full-year bill usually lands under what the flat rate suggests.
One more line that never shows up in national comparisons: Texas has no state income tax, so the same gross income to qualify leaves more money behind to live on.
Ways to raise your buying power when the math is tight
How much income you show is only half the equation. What we look at:
Pay down the right debt first. Not the biggest balance, the one whose minimum payment is highest the percentage of balance; car loans and credit cards with low balances are the usual best. A co-borrower on the loan, often a spouse or family member, adds their income to the qualifying calculation but also add their debts). A temporary buydown, where a seller credit buys a lower payment for the first year or two, can bridge a tight file; price one here.
Most importantly, get pre-approved before you shop. Once under contract: do not change employment status, since changing jobs after mortgage approval can will re-open underwriting at the worst time and lead to a multitude of other requirements to qualify.
No lender can promise an approval, us included. What we will do is show you the income to qualify before you fall in love with a listing.
FAQ
Not at most average interest rates and Texas property taxes and costs. A $50,000 annual income supports roughly $156,000 to $205,000 in purchase price with 10% down and no other debts. Reaching $300,000 would take a down payment near 40%, a co-borrower, and/or additional income.
