Temporary buydown or a permanently lower rate: which helps more?

A payment-sensitive buyer was comparing a 3-2-1 buydown with using seller funds for a permanently lower rate.

The lowest first-year payment was easy to notice. It was not the only number I wanted on the page.

What payment will you be carrying when the temporary help ends?

Understand what changes

A temporary buydown helps cover part of the payment for a set period. It does not lower the note rate itself.

In a typical 3-2-1 plan, the borrower's payment contribution is calculated using a rate three percentage points below the note rate in year one, two below in year two and one below in year three. The subsidy covers the difference.

Paying points for a permanent buydown buys different note-rate pricing at closing. It is a different use of upfront money.

The available plan and loan requirements need confirmation. For Fannie Mae temporary buydowns, qualification uses the note rate.

Put the later payment first

I would show the payment after the subsidy ends, including taxes, insurance, mortgage insurance and association dues.

If only the first-year payment feels comfortable, we need to revisit the purchase budget.

A future refinance or raise might happen. Neither should be required for the loan you sign to make sense.

Compare the same seller dollars

1. Show each year of the temporary payment plan and its cost.
2. Show the permanent option's rate, APR, points and full payment.
3. Consider whether paying other eligible closing costs would help more.
4. Check contribution limits and the cash left after closing.

Then ask what happens if you pay the loan off early. Unused temporary funds follow the written agreement; do not assume they come back as cash. Permanent points also need enough time to provide the benefit you expected.

I want the seller credit to solve the right problem for you. That might be a short-term transition, a lower ongoing payment or keeping more cash available. We should compare those choices before choosing the smallest first-year number.
