Collin County Mortgage Lender: The Move-Up Market

Collin County holds 1,297,179 people across 848 square miles, and it has roughly tripled in population since 1990. Its seat is McKinney, but the county's lending profile is set by the corporate campuses along the Dallas North Tollway and US 75 and the relocations that follow them.

What distinguishes Collin County from its neighbours is not price alone. It is how often the buyer already owns a house — here or in another state — and has to solve the timing problem before anything else. Most files in this county are a sale and a purchase pretending to be one transaction.

Buying here before selling there

A home equity line on the departing home can fund the down payment, but it must be opened before the house is listed; lenders will not open one on a property already on the market. In Texas, total borrowing against a homestead is capped at 80% of value, and the closing carries required waiting periods.

If the sale is already under firm contract, many lenders will exclude the old payment from your ratios, which frequently solves the problem outright.

If the old home becomes a rental, a signed lease and evidence of the deposit can let part of the rent offset the old payment, subject to specific documentation.

A recast after the sale lets you apply the proceeds to the new mortgage and have the payment recalculated on the lower balance without refinancing or changing the rate. Many conventional loans permit it; confirm before you choose the loan, because government-backed loans generally do not.

Our Circle C Ranch page works through the same four tools in detail.

For an out-of-state relocation, the sequencing is different again: a buyer carrying a mortgage in another state is qualified on both payments unless the sale closes first or the documentation above is in place.

Above the conforming limit, three structures compete

A meaningful share of Collin County purchases land above the 2026 conforming limit of $832,750 for a single-family home, and there is rarely one right answer.

Put enough down to stay conforming. Simple, and it preserves conventional guidelines — at the cost of liquidity you may want to keep.

Split the financing. A conforming first mortgage plus a second lien keeps the first loan under the limit and can avoid mortgage insurance, though the second carries a higher and often variable rate.

Take the jumbo. Jumbo pricing is not automatically worse; with strong credit and reserves it is frequently competitive. The trade is stricter underwriting, higher reserve requirements and sometimes two appraisals.

The right structure depends on your numbers on the day you lock, which is why we price all three rather than assuming. Our Northwest Hills page explains the comparison in full.

District assessments in the newer subdivisions

Collin County's growth outpaced its cities' ability to fund infrastructure directly, and much of the newer development carries the bill.

PID assessments repay roads, water and drainage over decades and must be disclosed by the seller before you sign.

MUDs levy their own rate in some areas on the county's northern and eastern edges.

Both go into the qualifying payment, reducing the loan amount your income supports.

Rates vary sharply between cities. Plano, Frisco, McKinney, Allen, Prosper and Celina each levy their own, over county, school district and Collin College. Two houses at the same price in different cities here can carry materially different escrows.

The Collin Central Appraisal District sets the values all of that is billed against; the homestead exemption caps annual increases at 10% once filed, and the protest deadline is typically mid-May.

Which programs fit Collin County

Conventional financing carries most of the market.

Jumbo appears constantly in Frisco, Prosper, Celina and west Plano.

FHA is used in the county's older southern cities and in its more affordable eastern towns, with the 2026 national floor at $541,287 and the county figure published by HUD.

VA lending is steady across the metro.

Bank statement and asset-based programs matter more here than the population alone suggests, because the corporate corridor produces business owners and equity-compensated employees whose tax returns understate them — see bank statement loans.

New construction is a large share of volume; the builder-lender comparison on our Tarrant County page applies equally here.

Where people buy

Plano anchors the southern county with established 1980s and 1990s stock alongside corporate campuses, and has its own guide.

Frisco and McKinney carry much of the newer construction and are covered separately.

Allen sits between them with a similar profile.

Prosper and Celina, on the northern edge, are where the current build-out is happening and where district assessments are most common.

Richardson, straddling the Dallas County line, mixes mid-century housing with the Telecom Corridor.

Farmersville, Princeton and the eastern towns hold the county's most affordable inventory and its remaining acreage.

Neighbouring counties

Collin borders Denton, Dallas, Rockwall, Hunt, Fannin and Grayson. Buyers comparing Collin against Denton County are usually comparing two similar houses with different district assessments, which is a payment comparison rather than a price one.

Towns and cities we lend in across Collin County

Plano, Frisco, McKinney and Allen carry most of the population. Prosper and Celina on the northern edge are where current construction concentrates. Wylie, Murphy and Sachse sit on the eastern side at lower prices. Richardson's Collin County portion falls in a different school district from its Dallas County half. Anna, Melissa and Princeton along US 75 north are absorbing growth quickly, and Farmersville and Blue Ridge remain small-town and semi-rural.

Assistance programs that reach Collin County

TDHCA and TSAHC programs reach every address in the county, and several Collin County cities have run their own assistance for income-qualified buyers. At Collin County price points the income limits exclude many buyers, which is worth checking early rather than planning around. For relocating professionals, the more useful programs are often lender-specific — physician and professional loans that treat student debt differently, and portfolio products that count restricted stock or bonus income a conventional file would discount.

Frequently asked questions

Who are the best mortgage lenders in Collin County, TX? For this county the differentiators are jumbo pricing, self-employed income handling and the ability to structure a purchase around a sale. A broker shopping several wholesale lenders will usually beat a single institution on at least one of those.

Can I buy in Collin County before selling my current home? Yes. The common routes are a home equity line opened before listing, qualifying for both payments, documenting the old home as a rental, or closing with a smaller down payment and recasting after the sale.

Do I need a jumbo loan in Collin County? Only above $832,750 for a single-family home in 2026. Many purchases here cross that line, and splitting the financing with a second lien is often a competitive alternative.

What is a PID assessment in Collin County? An annual charge repaying a subdivision's infrastructure, disclosed by the seller before signing. It is counted in your debt-to-income ratio like a tax.

Why do two similar houses in Collin County have different payments? Usually the city rate and any district assessment. The structures are comparable; the taxing units are not.

What is a mortgage recast and does it work here? A lump-sum principal payment after closing, after which the lender recalculates the monthly payment on the lower balance without a refinance. Many conventional loans allow it; confirm before choosing the loan.

Which appraisal district covers Collin County? The Collin Central Appraisal District. It sets assessed values, processes homestead exemptions and hears protests, typically with a mid-May deadline.

Is a jumbo loan harder to get than a conventional loan? It is underwritten more strictly rather than being fundamentally harder: expect larger reserve requirements measured in months of the full payment, tighter debt-to-income limits, and sometimes two appraisals on larger loans. Pricing is not automatically worse, and with strong credit and reserves it can beat a conforming loan that carries mortgage insurance.

How much do I need for a down payment in Collin County? It depends on the program rather than the county. What is specific to Collin County is that many purchases cross the $832,750 conforming limit, so the structure question — more down to stay conforming, a second lien, or a jumbo — usually matters more than the headline percentage. We price all three on the same day because the answer changes with the market.

Can I buy a house here before selling my current one? Yes, and most buyers in this county do. The four workable routes are a home equity line opened on the departing home before it is listed, qualifying for both payments, documenting the old home as a rental with a signed lease, or closing with less down and recasting the new loan after the sale. Which one fits depends on your equity and your income.
