What is an interest reserve on a hard money loan?

An interest reserve is a portion of the hard money loan set aside at closing to pay the borrower's monthly interest payments during the project. Instead of making out-of-pocket payments each month, the monthly interest is automatically deducted from the reserve balance. The borrower has zero monthly carrying cost until the reserve runs out. The reserve comes from the loan proceeds, reducing the productive capital available for acquisition and renovation.

Does an interest reserve reduce the money available for renovation?

Yes. An interest reserve is funded from the loan proceeds — it is not additional money. If the loan is $280,000 and the interest reserve is $15,400, only $264,600 is available for acquisition and renovation. This is why interest reserves involve a trade-off: zero monthly out-of-pocket cost during the project vs. less productive capital from day one.

Are interest reserves required on hard money loans?

Not always. Many hard money lenders make interest reserves optional on fix and flip loans. Some lenders require them on construction loans, particularly for first-time builders. Whether to include an interest reserve is usually the borrower's choice — it depends on their monthly cash flow tolerance, project length, and preference for productive capital vs. eliminated payment obligations.

Interest Reserve in Hard Money Lending: What It Is and How It Works

By Broker Cheetah Editorial Team · April 2026

Direct Answer

An interest reserve is a portion of a hard money loan set aside at closing to pay the borrower's monthly interest payments during the project. Instead of making out-of-pocket interest payments each month, the payments are drawn automatically from the reserve. The borrower gets zero monthly out-of-pocket carrying cost during renovation; the reserve is depleted each month until the loan is paid off or the reserve runs out.

How an Interest Reserve Works

At closing, the lender sets aside a specified dollar amount from the loan proceeds — the interest reserve. Each month, instead of the borrower writing a check, the monthly interest payment is deducted automatically from the reserve balance.

Example:

Loan amount: $280,000 (including holdback)
Interest rate: 11%
Monthly interest (Dutch basis): $280,000 × 11% ÷ 12 = $2,567
Interest reserve: $15,400 (6 months of payments)
Borrower's monthly out-of-pocket cost during project: $0

After 6 months, the reserve is depleted. If the project is not yet complete, the borrower begins making payments out of pocket.

How Interest Reserve Affects Loan Proceeds

The interest reserve comes from the loan — not from outside capital. This means it reduces the cash the borrower receives at closing and reduces the effective funds available for the project.

If the loan is $280,000 and $15,400 is allocated to the interest reserve, the borrower has:

$200,000 for acquisition (disbursed at close)
$80,000 for the rehab holdback (drawn during renovation)
$15,400 for the interest reserve (never available as cash — used only for payments)

The total loan commitment is $280,000 but the borrower's actual productive capital is $264,600.

This is why interest reserves are sometimes treated as a separate line item on the loan, and why they appear on the settlement statement.

When Interest Reserves Make Sense

When the borrower wants to minimize monthly cash obligations during a project. A borrower managing a demanding renovation with contractor payments going out constantly may prefer to not have a monthly loan payment on top of everything else. The interest reserve handles it automatically.

When the lender requires it. Some hard money lenders require an interest reserve on construction loans, particularly for first-time builders. It reduces the risk of the borrower missing payments during a long construction period.

When the project timeline is uncertain. If the borrower is not sure whether the project will take 4 months or 8 months, a larger interest reserve buys flexibility without monthly payment stress.

When Interest Reserves Do Not Make Sense

When the borrower wants maximum productive capital. Every dollar in the interest reserve is a dollar that cannot be used for acquisition or renovation. A borrower who can comfortably make monthly interest payments out of cash reserves may prefer to skip the interest reserve and have more project capital available.

When the project is short. If the renovation is expected to take 60-90 days, an interest reserve covering 6 months of payments is unnecessary capital tied up. The borrower can make 2-3 payments out of pocket and keep the money in productive use.

When the loan is non-Dutch. On a non-Dutch loan, early monthly payments are small (only on the disbursed acquisition portion). The borrower may prefer to make those small early payments directly rather than tying up a larger reserve.

Interest Reserve vs. Holdback

Both are portions of the loan held back at closing, but they serve different purposes:

Holdback: Funds reserved for renovation, released as construction milestones are completed. The borrower draws this money and spends it on renovation.

Interest reserve: Funds reserved for loan payments. The borrower never receives or spends this money directly — it is automatically applied to monthly interest payments.

Both reduce the cash available to the borrower at closing. Both appear as separate line items in the loan structure.
