Tarrant County Mortgage Lender: Buying New, and What It Costs You

Tarrant County holds 2,248,466 people across 864 square miles — the third-largest county in Texas, and the one where the Dallas–Fort Worth metro's new construction volume concentrates on the western side. Its seat is Fort Worth.

The county splits cleanly in two for lending purposes. South and east, the stock is established and the questions resemble Dallas County's. North and northwest, along the Alliance corridor and out toward Haslet, Justin and Northlake, it is new build after new build — and a new build is a different transaction with a different set of traps.

The builder's lender, and how to compare it honestly

Nearly every production builder in north Tarrant offers an incentive to use its affiliated mortgage company: closing cost credits, a rate buydown, or upgrades.

You cannot be required to use them. A builder may reward you for it; it may not condition the sale on it.

The incentive is real money and often worth taking. The question is never whether the incentive is large, it is whether the total package beats the alternative.

Compare Loan Estimates issued the same day, for the same program, the same down payment and the same lock period. The form is standardised precisely so this comparison is possible.

Watch the rate behind the credit. A generous closing cost credit funded by a higher note rate can cost more over any reasonable holding period than it saves at the table.

Ask what happens if you decline. Some builders shift the incentive to price or to upgrades; some withdraw it. Get the answer in writing before you sign.

Our Manor page works through the same comparison in detail, and the arithmetic is identical here.

Locking a rate on a house that does not exist yet

A build that completes in six months cannot be locked like a resale closing in thirty days.

Extended locks cost something, usually priced into the rate, and the cost rises with the length.

Float-down provisions are worth asking about by name: they let you capture a lower market if rates fall during construction.

Completion slips. City inspections, materials and weather all move dates, and a lock that expires before the certificate of occupancy issues means re-pricing at whatever the market is that week.

You close on a finished house. Lenders require the certificate of occupancy and a completed final inspection, so the lock has to cover the real schedule, not the optimistic one.

PIDs, MUDs and what the subdivision is still paying for

North Tarrant's growth was built on districts, and they appear on your tax bill or alongside it.

A public improvement district assessment repays the cost of roads, water lines and drainage, usually over decades. Texas law requires the seller to notify you of a PID obligation before you sign — read it for the annual amount and the remaining term.

A municipal utility district levies its own tax rate for the same purpose.

Both count in your debt-to-income ratio, which means they reduce the loan amount you qualify for, not merely the comfort of the payment.

Some PID assessments can be prepaid. Whether that is worth doing depends on the balance, the remaining term and what else you would do with the cash.

TAD, your escrow and the first-year value

The Tarrant Appraisal District values every parcel in the county.

A new home is assessed on the finished structure. If your house completed after January 1, the first tax bill may reflect land only, and the second will reflect the house. Escrow for the finished value from the start or you will face a shortage and a payment jump in year two.

File the homestead exemption the year you move in. It lowers taxable value and caps annual increases at 10% while you hold and occupy.

Rates differ sharply across the county. Fort Worth, Arlington, Keller, Mansfield and the smaller northern towns each levy their own, on top of county, school, Tarrant County College and the hospital district.

Which programs fit Tarrant County

Conventional financing dominates the new-build market, with the 2026 conforming limit at $832,750 for a single-family home.

FHA carries a large share of the county's first-purchase volume, especially south and east. The 2026 national floor is $541,287; HUD publishes the county figure.

VA lending is significant, with Naval Air Station Fort Worth Joint Reserve Base in the county and a large veteran population across the metro.

Jumbo appears in Westlake, Southlake and Colleyville.

DSCR financing supports investors in the established eastern cities; see DSCR loans.

Renovation loans fit the pre-1980 stock in east Fort Worth and Arlington.

Where people buy

Fort Worth itself spans nearly every price band in the county and has its own guide.

Arlington, between the two downtowns, carries a large established market and a deep rental base.

Grand Prairie straddles the county line and is covered separately.

The northern corridor — Haslet, Justin, Northlake and the Alliance area — is where the district assessments described above are most common.

Southlake, Colleyville and Keller in the northeast carry the county's highest prices and the most jumbo volume.

Mansfield and the south, toward Johnson County, mix newer subdivisions with acreage at the edges.

Neighbouring counties

Tarrant borders Denton, Dallas, Ellis, Johnson, Parker and Wise. Buyers routinely cross those lines chasing price, and the comparison is rarely price alone — the district assessments and the school rate often matter more.

Towns and cities we lend in across Tarrant County

Fort Worth and Arlington are the two large cities, each with its own rate. Southlake, Colleyville, Keller and Grapevine form the affluent northeast, mostly in the Carroll, Grapevine-Colleyville and Keller school districts. Mansfield, Burleson and Crowley run south toward Johnson County. North Richland Hills, Hurst, Euless and Bedford fill the mid-cities between the two downtowns with 1960s to 1980s stock. Haslet, Justin, Northlake and Roanoke carry the northern build-out and most of the district assessments.

Assistance programs that reach Tarrant County

Fort Worth and Arlington each administer homebuyer assistance for income-qualified buyers inside their city limits, and Tarrant County has run its own program for unincorporated areas and smaller cities. TDHCA and TSAHC reach the whole county, including the Homes for Texas Heroes programme for teachers, first responders and veterans. Several of these can be layered with a builder incentive, but not all builders accept assistance liens, so confirm that with the builder before signing.

Frequently asked questions

Who are the best mortgage lenders in Tarrant County, TX? For a new build, the answer turns on lock length and the ability to price against a builder's incentive. For an older home in Arlington or east Fort Worth it turns on renovation and condition handling. Those are different strengths, which is the argument for a broker shopping a panel rather than one lender's shelf.

Do I have to use the builder's lender in Tarrant County? No. A builder can offer incentives for using its affiliated lender but cannot require it. Compare Loan Estimates from both on the same day for the same program.

What is a PID assessment and will it affect my loan? It is an annual charge repaying a subdivision's public improvements, separate from property tax and often running decades. Lenders include it in your debt-to-income ratio, so it lowers the loan amount you qualify for.

How long should I lock a rate on new construction? Long enough to cover the real completion date with margin. Extended locks cost more, and so does re-pricing after a lock expires, so ask about both the extension cost and any float-down option.

Why did my property tax jump in the second year? Because the first bill likely covered land only. Once the finished house is on the roll, the assessed value — and the escrow — reflect the whole property.

What does the Tarrant Appraisal District do? It sets the assessed value every taxing unit bills against, and it is where you file your homestead exemption and any protest. The protest deadline is typically mid-May.

Is north Tarrant County more expensive to own than Fort Worth proper? Sometimes, even at a lower purchase price, because district assessments can offset the difference. Compare total monthly cost on two specific addresses rather than price per square foot.

Should I use the builder's lender or my own in Tarrant County? Compare the complete offers rather than the incentive alone. A builder credit funded by a higher note rate can cost more over any realistic holding period than it saves at closing. Get Loan Estimates from both on the same day, for the same program, down payment and lock length, and compare the rate, the points and the lock cost together.

How much are property taxes in Tarrant County? The total stacks the city, Tarrant County, the school district, Tarrant County College and the hospital district, and it differs between Fort Worth, Arlington, Keller and the smaller northern towns. New subdivisions may add a PID assessment or MUD rate on top. Use the parcel's tax certificate rather than a county average, because the spread is wide enough to change what you qualify for.

Can I buy a new construction home with an FHA loan in Tarrant County? Yes, and it is common in the county's mid-market. The practical constraints are the same as any new build: the home must be complete with a certificate of occupancy before closing, the rate lock has to cover the construction timeline, and the first tax bill may reflect the lot alone while the finished value lands the following year.
