Interest Rate Buydowns on Apartment Loans: Temporary vs. Permanent
On this page
An interest rate buydown is an upfront payment that lowers the interest rate on a loan. A sponsor might pay a lump sum at closing so the loan's rate is lower for the first one or two years, or pay for a lower rate for the whole term. The buydown raises the cash needed at closing in exchange for lower payments later.
This guide explains the two main types, how to price each one and what a lender may and may not allow.

What are the two types?
Temporary buydown. The rate is reduced for an early period, often one to three years, then steps up to the note rate. A common shape is a rate that is two points lower in year one and one point lower in year two. The sponsor pays the difference in payments up front, usually into an escrow account the lender holds.
Permanent buydown. The rate is lowered for the full term. It costs more, and it changes the loan's pricing for the life of the loan.
How is a buydown priced?
The buydown cost equals the payments the borrower would have made at the note rate minus the payments at the lower rate, discounted to today's value. The lender usually quotes the number. Ask for the buydown schedule in writing, with each year's rate, payment and total cost.
Two facts drive the price: the size of the rate cut and the length of time it lasts. A deeper or longer cut costs more.
A hypothetical example
These numbers are made up for illustration. Your lender's quote will differ.
| Item | Amount |
|---|---|
| Loan amount | $8,000,000 |
| Note rate (made up) | 6.00%, 30-year amortization |
| Year 1 rate with the buydown | 4.00% |
| Year 2 rate with the buydown | 5.00% |
| Monthly payment saving in year 1 (about $48,000 at 6% vs. about $38,300 at 4%) | about $9,700 a month |
| Monthly payment saving in year 2 (about $43,000 at 5%) | about $5,000 a month |
| Total payment savings over two years | about $176,000 |
| Buydown cost paid at closing (made up, near the present value of the savings) | $165,000 |
The sponsor pays $165,000 at closing to reduce payments in the first two years. This helps only if the building's cash flow in those years is tight and the value rises enough to refinance or sell when the buydown ends. Check whether the building can cover the full note-rate payment after the buydown, because that is the payment the business plan must support.
When does a buydown make sense?
- The building is in lease-up, and rents will rise as units turn over.
- A temporary rate cut keeps the early years positive for investors without changing the long-term plan.
- The sponsor has cash for the upfront cost and the cost is less than the expected cash flow gap it covers.
When should you skip it?
- The deal already fails at the note rate. A buydown hides the problem for a while.
- The lender does not allow it, or the buydown is paid by money the rules do not permit.
- The cash used for the buydown is needed for repairs or reserves.
- Investors are shown the early-year payment and not the payment after the buydown ends.
What to check with the lender
- Is a buydown allowed on this loan, and who may pay for it?
- What is the exact schedule of rates and payments, and the total cost?
- Is the buydown funded into escrow, and what happens to any unused money?
- Does the buydown change the loan size, the debt service coverage test or the covenants?
- What rate applies after the buydown, and is it the rate used in the projections?

How DoorRaise fits in
DoorRaise helps sponsors raise equity for apartment buildings with 5 or more units under Rule 506(b) or 506(c). The deal's sources and uses show any buydown cost, and the projected returns subtract it so investors see the real cash flow. Setup is $1,500 (non-refundable), and the administration fee is $5,000 a year from closing.

FAQ
Is a rate buydown the same as a rate cap?
No. A buydown pays to lower the rate on the loan's schedule. A rate cap is a separate contract that limits how high a floating rate can go.
Who can pay for a buydown?
It depends on the lender and the loan program. Some allow the seller or the sponsor to pay, with limits. Ask the lender for the rule in writing.
Does a buydown lower the loan balance?
No. It lowers the payments, not the principal. The balance still has to be repaid on the loan's terms.
What happens when a temporary buydown ends?
The payment rises to the note-rate payment. The business plan must support that payment, or the sponsor must refinance or sell first.
