North Texas

Dallas County Mortgage Lender: Old Houses, High Rates, Tight Margins

Dallas County holds 2,661,397 people in 880 square miles, which makes it the second-largest county in Texas and one of the most densely built. Unlike the metro's growth counties to the north, Dallas County is mostly already built out — and the age of what is standing is the defining fact of lending here.

A large share of the county's housing predates 1980. That shapes three things at once: what an inspection turns up, what an insurer will write, and what an appraiser can support. Buyers who budget for the price and the rate, then meet the roof, the panel and the sewer line, are the most common difficult conversation we have in this county.

Financing a house built before 1980

The electrical panel decides the insurance. Certain panel brands installed through the 1960s and 1970s are declined outright by many carriers. That is an insurance problem before it is a mortgage problem, and insurance is a condition of closing.

Cast iron drain lines were standard in this era and corrode from the inside. A camera inspection of the main line costs little; replacing it under a slab does not.

Foundations move on North Texas clay. Seasonal movement is normal; a failed foundation is not, and the difference is a structural engineer's opinion rather than a general inspector's note.

Asbestos and lead are present in flooring, textured ceilings and paint of that period. Both change the cost and the sequence of any renovation.

None of this blocks a loan. It changes which loan. If the repair list is long, a renovation mortgage finances the purchase and the work together, sized on the home's value after completion rather than its condition today — the mechanics are on our Barton Hills page, and they work identically here.

DCAD, your escrow, and why the listing's tax figure misleads

The Dallas Central Appraisal District values every parcel in the county, and your lender escrows against that value, not the price you paid.

The tax line on the listing reflects the seller. Their exemptions, their capped value, their circumstances. A sale resets the appraisal to market and ends their exemptions at closing.

Combined rates in the county stack the city, Dallas County, the school district, Dallas College and Parkland Hospital District. The total varies meaningfully between cities inside the county, and that difference is worth more than a small rate concession.

The homestead cap is the long game. Filing in your first year limits annual increases in assessed value to 10% for as long as you hold and occupy the home.

Protest in year one. Your closing statement is evidence of market value, and it is the strongest evidence you will ever hand the district. The deadline is typically mid-May.

Condos and townhomes carry a second approval

Dallas County has a deep attached-housing market, and a condo loan is two approvals: the borrower and the project.

The association completes a questionnaire covering budget, reserves, delinquency, litigation, commercial space and how many units are investor-owned. Ask for it during the option period.

Projects fail on predictable things — a special assessment in progress, construction-defect litigation, a single owner holding too many units, or reserves below guideline. Any of those can push a loan from standard conventional pricing into a non-warrantable product with a larger down payment.

Townhomes that own their land are not condos. They finance as single-family homes even though they share walls. What governs is how the property is recorded, not what it looks like, and the title commitment says which.

Which programs fit Dallas County

Conventional financing carries most of the market, with the 2026 conforming limit at $832,750 for a single-family home.

FHA is widely used across the county's mid-market, and its flexibility on credit suits buyers whose file has a blemish rather than a pattern. The 2026 national floor is $541,287; the Dallas County figure is set above it, and HUD's lookup is the only reliable source for it.

Jumbo takes over in the Park Cities and the northern tier of the county.

Renovation financing fits the county's age profile better than it fits almost anywhere else in Texas.

DSCR suits the investor market, qualifying on the property's rent against its payment instead of your tax returns — see DSCR loans.

Our Dallas city page covers the city market and jumbo financing in more depth.

Where people buy

East Dallas and the M Streets hold 1920s and 1930s Tudors and bungalows, many renovated at least once, with the oldest systems in the county.

Oak Cliff, south of the river, mixes early-century housing with substantial new infill.

North Dallas carries the 1960s and 1970s ranch stock that defines the county's middle market.

Irving and Garland are large cities in their own right inside the county, each with its own rate stack and its own guide.

Mesquite and Grand Prairie anchor the eastern and western edges, both covered separately.

Neighbouring counties

Dallas borders Collin, Denton, Tarrant, Ellis, Kaufman and Rockwall. Every one has a different appraisal district and a different combined rate, and in a metro where people shop across county lines routinely, that difference belongs in the comparison.

Towns and cities we lend in across Dallas County

Irving, Garland, Mesquite and Grand Prairie are large cities in their own right inside the county, each levying its own rate. Richardson straddles the Collin County line. DeSoto, Duncanville, Cedar Hill and Lancaster form the southern tier, where prices sit below the county median and FHA volume concentrates. Balch Springs, Seagoville and Hutchins hold the county's most affordable detached housing. Highland Park and University Park, surrounded by the city of Dallas, carry their own school district and the county's highest prices.

Assistance programs that reach Dallas County

The City of Dallas runs a homebuyer assistance program for income-qualified buyers purchasing inside the city, and several of the smaller cities in the county administer their own. Statewide, TDHCA's My First Texas Home and TSAHC's Homes for Texas Heroes reach every address in the county, the latter aimed at teachers, first responders, corrections officers and veterans. Funding for all of these opens and closes through the year, and layering one onto an FHA or conventional loan changes the underwriting, so ask before you write an offer rather than after.

Frequently asked questions

Who are the best mortgage lenders in Dallas County, TX? It depends on the property as much as the borrower. A 1935 bungalow needing systems work, a non-warrantable condo downtown and a new build in the northern suburbs are three different underwriting problems, and few lenders are strongest at all three. Working through a broker means the file goes to whichever wholesale lender fits it.

Can I get a mortgage on a house built in the 1950s? Yes. Age alone is not a lending obstacle. What matters is condition: the roof, the electrical panel, the plumbing and the foundation, in that order, because those drive both insurability and appraised value.

What is the property tax rate in Dallas County? There is no single rate. The total stacks the city, Dallas County, the school district, Dallas College and Parkland Hospital District, and it varies by which city within the county you buy in. Use the parcel's tax certificate rather than a county average.

Why is my tax bill higher than the listing said? Because the listing showed the seller's bill. Their exemptions ended at closing and the sale reset the appraised value to what you paid.

Is a condo harder to finance than a house in Dallas? It can be, because the lender approves the project as well as you. Reserves, delinquencies, litigation and investor concentration all affect eligibility. Request the association's questionnaire and budget during the option period.

When is the protest deadline for DCAD? Typically mid-May. Protesting in your first year, with your closing statement as evidence, is usually the most straightforward protest you will file.

Should I buy in Dallas County or one of the collar counties? It is a genuine trade: Dallas County has older stock, established neighbourhoods and shorter commutes, while Collin and Denton counties carry newer construction and, often, district assessments. The right answer is a payment comparison on two specific addresses, which we will run.

Is it cheaper to buy in Dallas County or Collin County? Collin County generally carries newer housing and, in many subdivisions, district assessments that Dallas County's established neighbourhoods do not. Dallas County carries older housing with higher maintenance and insurance exposure. The honest comparison is total monthly cost on two specific addresses, including taxes, insurance and any district charge, rather than price per square foot.

What credit score do I need to buy a house in Dallas County? There is no county-specific minimum; the thresholds are set by program. FHA reaches lower scores than conventional, VA has no published minimum though lenders set their own, and pricing improves in bands as the score rises. What matters more on an older Dallas County home is often the property's condition, because insurability can stop a file a good score would otherwise carry.

How long does it take to close on a house in Dallas County? Thirty days is a normal target on a resale with a clean file. Older housing adds steps — a sewer camera inspection, an electrical evaluation or an insurance binder that takes a second carrier — and those are what move the date. Starting the loan file before you are under contract is the single biggest thing that protects the timeline.

Price the repairs with the rate

In Dallas County the condition of the house moves the deal more than a small difference in rate. Send us the address and the inspection, and we will tell you which loan structure carries it.
