How Much House Can You Afford in 2026? Cash to Close Explained

How much house you can afford comes down to the payment, not the price tag. Lenders look at your income and your debts, translate them into a monthly housing payment you can support, and then the closing check is a separate number you plan on its own. Both are predictable, and both can be improved before you ever make an offer. Let's break this down the way I do with buyers in Patriot Nation: income first, then the payment, then the cash-to-close check.

What does "how much house can I afford" actually mean?

The honest answer: it means the mortgage payment your income and debts will comfortably support, plus the cash you bring on closing day. Most first-time buyers I talk to focus only on the price tag, then get surprised by the payment and the closing check. Here's the key: neither number is a mystery, both can be calculated before you shop, and both can be improved with a little time on your side.

Where the math starts: your income and your debt-to-income ratio

Lenders don't pick a dollar amount out of thin air. They start with your gross monthly income, add up your minimum monthly debts, and compare the two with something called debt-to-income ratio, DTI for short. There are two of them worth knowing:

• Front-end (housing) ratio: your total housing payment divided by your gross monthly income.
• Back-end (total debt) ratio: every monthly debt you have, including the new housing payment, divided by your gross monthly income.

Here's a quick look at the kind of guideline ranges used in everyday underwriting. Treat these as examples, not promises, because every program and every lender has its own limits.

Here's a pearl for you: as a round-number example, a buyer earning $6,000 a month gross with a 38% front-end benchmark could carry a housing payment around $2,280. That's a math example, not a quote. Your loan officer runs your actual numbers against the specific program you choose, and that's the number that should drive your house hunting, not a listing's asking price.

The five parts of a mortgage payment

Your monthly payment is built from five pieces. Knowing each one is the difference between understanding your quote and just staring at it. Here are the parts, in order:

1. Principal. The part that pays down what you borrowed. This is your equity being built.
2. Interest. The cost of borrowing the money, driven by your rate and your term.
3. Property taxes. In Texas these are collected with your payment and paid to the county for you.
4. Homeowners insurance. Your hazard policy, also collected with the payment.
5. HOA dues or mortgage insurance. If the property has a homeowners association, or your loan type carries mortgage insurance, that's part of the payment too.

Cash to close: the three buckets

Your cash to close is everything you bring on closing day, and it's bigger than the down payment. I teach buyers to think of it as three buckets, and once you see all three, nothing at the table can surprise you.

Bucket 1: the down payment

The down payment is the only part of your cash to close that buys ownership instead of paying for services. It's set as a percentage of the price by your loan type, usually in the single digits for most first-time buyers: FHA at 3.5%, many conventional programs at 3%, and zero for eligible VA and USDA buyers. Whatever percentage your program requires, that money becomes your equity from day one.

Bucket 2: closing costs and transaction costs

Bucket two is the service side of the deal: the one-time lender, title, and third-party charges that make the transaction happen, plus the government recording fees. In Texas these commonly run about 2% to 5% of the purchase price, separate from the down payment. You can't skip them, but you can plan for them, and seller concessions can shrink the part you actually bring.

Bucket 3: prepaids and escrows

Bucket three is money collected at closing for costs that come due later. Prepaid interest covers the gap between closing day and your first mortgage payment. Your homeowners insurance is paid up front, and the lender withholds part of your property taxes into escrow so they're paid when they're due. These reserves aren't wasted money, they're timing, and they're part of the total check you plan for.

How seller concessions and down payment assistance shrink the check

Here's the part that changes the plan for most first-time buyers: that total check is usually not the final number.

Seller concessions let the seller pay part of your closing costs out of the deal, and down payment assistance stacks on top of that through Texas state and San Antonio programs for qualified buyers. Combine the two and the check you actually bring can drop well below the down payment alone. The specific caps, program names, and qualification rules are the detail that wins deals, and that's the full framework Patrick walks through live on November 5, program by program, with your own numbers.

Affordability and the closing check, or every dollar of the deal?

This post covers the two numbers that matter most: the monthly payment your income supports and the closing check. If you want the item-by-item breakdown of every dollar you could be asked to bring, my post How Much Money Do You Need to Buy a Home? digs into each of the three buckets line by line. The two posts are two different questions: what can I support each month, and what cash do I physically need on hand, and both deserve their own plan.

If you're wondering how your own numbers might line up, the FAQ page answers the common credit, down payment, and closing questions, and the Save My Seat buttons on this page take you straight to the free live webinar on the homepage, where I run the real numbers with buyers live. Here's the hope for this post: you understand your payment and your three buckets better now, and on November 5 you'll leave with your own numbers filled in, so bring your questions and I'll walk your situation through the full framework live at 7:00 PM Central.
