How Much House Can I Realistically Afford in McKinney, TX With Today's Interest Rates and Taxes?
This is the question that separates wishful thinking from a real plan — and I appreciate every buyer who asks it before they start touring homes. After 23 years in real estate and over 1,150 closings, I've seen what happens when people skip this step. Let's not do that.
The McKinney Affordability Equation in 2026
There are four numbers you need to get comfortable with before you shop in McKinney TX real estate in 2026: your purchase price ceiling, your monthly payment including taxes and insurance, your down payment, and your debt-to-income ratio. Lenders are looking hard at all four.
Here's a rough framework for 2026 McKinney buyers assuming a conventional 30-year loan:
At $350,000 purchase price: Expect a total monthly payment (PITI — principal, interest, taxes, insurance) of approximately $2,800–$3,100 depending on your rate and escrow.
At $500,000 purchase price: You're looking at roughly $3,900–$4,300/month all-in.
At $700,000 purchase price: Plan for $5,300–$5,800/month before any HOA fees.
These are estimates — your actual numbers depend on your credit score, down payment, and the specific community you're buying in (more on taxes in a moment).
The Texas Property Tax Reality
Texas has no state income tax — but it makes up for it with property taxes that are among the highest in the nation. In McKinney and Collin County, effective tax rates typically run between 1.8% and 2.4% of assessed value annually, depending on the specific taxing entities in your neighborhood (MUD districts, PIDs, and school district levies all layer on top of each other).
On a $500,000 home, that can mean $9,000–$12,000 per year in property taxes — or $750–$1,000 added to your monthly payment. This is not a small number, and it's one that catches buyers off guard if they've been pre-approved based on a lender's national tax estimate.
Always verify the actual tax rate for a specific address before you make an offer. Bob can help you with this, or browse current listings by price range — like McKinney TX homes between $600k and $800k — and look up the tax ID for each one.
Down Payment: How Much Do You Really Need?
Conventional wisdom says 20% down to avoid PMI, but in today's market, many McKinney buyers are using 5%–10% down and factoring PMI into their budget. FHA loans allow as little as 3.5% down. VA loans, for eligible buyers, offer zero down with no PMI.
The tradeoff is always monthly payment vs. preserved cash. In a market where prices have held relatively firm, preserving liquidity can be smart — but running a thin down payment in a higher-rate environment squeezes your monthly budget. This is a conversation worth having with both your lender and your agent.
What Bob Recommends Before You Tour a Single Home

"The biggest mistake I see is buyers who fall in love with a house before they know their real number. Getting pre-approved first isn't just a box to check — it's what makes your offer competitive." — Bob McCranie
