Affordability is not a single number. It is the point where the monthly payment, your down payment, and your comfort level all line up. Here is how new-home buyers in North Texas usually get to that number.
Most buyers shop by list price. Lenders shop by monthly payment. Your payment on a new home in Texas is made up of four parts, often shortened to PITI: principal, interest, property taxes, and insurance. If the community has an HOA, or a MUD or PID assessment, that gets added on top.
Texas has no state income tax, but property tax rates are higher than the national average, so taxes are a much larger slice of the payment here than in many other states. Two homes at the same price in two different tax jurisdictions can have meaningfully different monthly payments.
Lenders look at your debt-to-income ratio (DTI): all of your recurring monthly debt payments, including the new mortgage, divided by your gross monthly income. Different loan programs allow different maximums, and compensating factors like reserves or a larger down payment can widen the range.
They also look at your credit score, your employment history, and how much cash you have left after closing. Two buyers with the same income can qualify for very different amounts based on car payments, student loans, and credit card balances.
Twenty percent is a common assumption, but it is not a requirement for most buyers. Conventional, FHA, VA, and USDA loans all have different minimums, and parts of the North Texas area outside the urban core can qualify for USDA rural financing. Putting less than twenty percent down usually means mortgage insurance, which raises the monthly payment.
Budget for closing costs separately from the down payment, and keep a cushion for window coverings, fencing, landscaping, and the small things that come with a brand-new home.
Pick the monthly payment you are comfortable with first. Then work backwards with a lender to see what price that supports at current rates, in the specific tax jurisdiction where you want to live. Get a written pre-approval before you tour, so you are comparing real options.
Rates move. A pre-approval from a few months ago may no longer reflect your buying power, in either direction.
There is no single figure. It depends on the price, the tax rate in that city and county, your other monthly debts, your credit, and the loan program. The fastest way to get a real answer is a pre-approval, which is free and usually takes a day or two.
Significantly. Texas property tax rates are set locally by cities, counties, school districts, and special districts, so the same purchase price can carry different monthly payments depending on where the home sits. Always compare payments, not just list prices.
It depends on the market and the home. New construction typically means a builder warranty, current building codes, and new systems and appliances, which can lower early maintenance costs. Builders may also offer incentives that resale sellers do not.
