What a Builder's 'Preferred Lender' Incentive Actually Costs You in Johnson County

Almost every new-construction buyer I've worked with this year has hit the same moment. They're sitting in a design center or a model home somewhere in south Overland Park or Olathe, and the sales counselor slides a sheet across the table: "The builder will contribute $15,000 toward closing costs, or buy your rate down, if you use our preferred lender and title company."

It sounds like free money. Sometimes it is. Sometimes it's an expensive way to get a slightly worse loan. The problem is that the sheet doesn't tell you which one you're looking at, and the person handing it to you works for the builder. So let's price the string.

What the incentive actually is

Builders in Johnson County have room to negotiate again. I covered this in the Overland Park and Olathe new-construction guides: rate buydowns, lot-premium credits and appliance packages are all back on the table in a way they weren't in 2023 and 2024. But the financing-related incentives almost always come with a condition attached, and the condition is the lender.

In practice you'll see one of three shapes:

A flat closing-cost credit. A fixed dollar amount (I've seen $5,000 to $20,000 depending on the builder and the price point) applied to your closing costs, prepaids or discount points. Only valid if you close with the builder's lender.

A temporary rate buydown. Usually a 2-1 or 3-2-1 structure: your rate is reduced by two or three points in year one, one or two in year two, then goes to the note rate. The builder funds the difference up front through the lender.

A permanent rate buydown. The builder pays discount points to lower your rate for the life of the loan. This is the most valuable version and, not coincidentally, the least common.

Why do builders do this? Two reasons that both come down to control. A big production builder usually has an in-house or affiliated mortgage company, so the "incentive" is partly moving money from one pocket to another. And a captive lender means fewer surprises: the builder knows the loan will close on schedule, which matters when they've got twelve homes finishing the same month and construction loans of their own to pay off.

Where the cost hides

Here's what a builder's sheet never says out loud: the credit is only worth something if the loan it's attached to is competitively priced. If the preferred lender's rate is a quarter point higher than what you could get outside, the "free" $15,000 might be paying for itself over the life of the loan and then some.

Let me put illustrative numbers on it. Say you're buying a $750,000 home in Sundance Ridge with 20 percent down, so a $600,000 loan. A quarter-point rate difference on that loan is roughly $95 to $100 a month. Over seven years, which is about how long most of my clients actually stay in a house before they move up or relocate, that's around $8,000. Over thirty years it's north of $34,000. Now the $15,000 credit looks like a wash at best, and a loss if you keep the house.

And the mismatch is often bigger than a quarter point. Not because builder lenders are crooked, but because they don't have to compete for you. You've already committed to the house. The incentive is the reason you're in their office, not their pricing.

The title company side works the same way, just smaller. Builder-affiliated title companies usually charge market-rate fees, but you've given up the ability to shop those fees, and a few hundred dollars here and there on a settlement statement adds up.

The fifteen-minute comparison

This is the part I actually want you to do, and it doesn't take long.

Step one: get the preferred lender's Loan Estimate. Not a rate sheet, not a verbal quote. The federally required Loan Estimate, with the incentive applied. That gives you the rate, the points, the lender fees and the total cash to close on one page.

Step two: get one outside Loan Estimate on the same day. Rates move daily, so same-day matters. Use a lender you've already been pre-approved with, or one I'll introduce you to. Tell them exactly what you're comparing against.

Step three: compare three numbers. The interest rate at the same number of points. The total lender fees (origination, underwriting, processing, whatever they call it). And the cash to close after the builder credit is applied to the preferred lender's side.

Step four: run the break-even. Take the monthly payment difference between the two loans and divide the builder credit by it. If the credit is $15,000 and the outside loan saves you $100 a month, the incentive stops being worth anything in month 150, or about twelve and a half years. If you'll be in the house less than that, the incentive wins. If you'll be there longer, the outside loan wins.

Most of the time, on a well-priced production build in a community like Mills Farm or the Olathe 175th Street corridor, the incentive comes out ahead for a seven-year hold. But I've had it go the other way more than once, and the buyers in those cases had no idea until we ran the numbers.

The three questions to ask before you sign

"Is the incentive available if I use my own lender?" Sometimes the answer is yes, at a reduced amount. A builder who'll give you $15,000 with their lender will occasionally give you $7,500 with yours. You don't know until you ask, and it's much easier to ask before the purchase agreement is signed than after. This belongs in the contract, which is why it's on my list of builder contract clauses to understand before you sign.

"Can I lock now, and what happens if the house is late?" A to-be-built home in Johnson County runs eight to twelve months from contract to keys. A rate lock that expires before your closing date is a rate lock you don't have. Ask about extended locks, float-down options and what happens to the buydown if the completion date slips, which it usually does.

"What is the incentive tied to, exactly?" Read the fine print on the sheet. Some incentives require both the lender and the title company. Some require the lender only. Some are worded so the credit can only be applied to certain fees, which means a chunk of it goes unused if your closing costs come in lower than the credit.

Where your agent comes in

The sales counselor in the model home is good at their job, and their job is selling the builder's homes and the builder's loans. That's not a criticism. It's just why you should have your own agent on a new build, and why I'm careful never to push a client toward any lender, mine or anyone else's. I'll get you the outside Loan Estimate, sit with you through the comparison, and negotiate the incentive language into the purchase agreement so the numbers you were promised are the numbers you get at the closing table.

One more thing worth saying plainly. A lender incentive is one line item in a much bigger decision. The lot premium, the allowance structure, which upgrades actually hold their value and whether the builder is production, semi-custom or custom (I mapped that out in who builds where in Johnson County) all move the total cost of the house more than a closing-cost credit does. Don't let a $15,000 sheet distract you from a $40,000 lot premium.

If you're looking at new construction anywhere in Johnson County and want a second set of eyes on the incentive sheet before you sign, reach out. Bring the Loan Estimate. We'll have an answer in fifteen minutes.

The dollar figures in this post are illustrative examples, not rate quotes. Rates, fees and builder incentives change daily and vary by builder, community and loan program. Always compare current Loan Estimates from a licensed lender before making a financing decision.
