Interest-Only Payments on Hard Money Loans: How Monthly Costs Work
A $300,000 hard money loan at 11% costs roughly $2,750 per month during the term. That figure surprises borrowers who expect a traditional mortgage-style bill. The reason is structure: interest only hard money payments cover the cost of borrowing, not the principal balance.
This post breaks down exactly how those monthly costs are calculated. You will see the formula, worked examples at different loan amounts, and what changes your bill from month to month.
What Interest-Only Payments Mean on a Hard Money Loan
An interest-only payment is a monthly payment that covers accrued interest and nothing toward the loan balance. Your principal stays the same for the full term.
Most hard money loans use this structure because the terms are short. A typical loan runs 6 to 18 months. Paying down principal over that window makes little sense when the exit is a sale or refinance.
The full principal comes due at the end in a single balloon payment. Until then, your monthly hard money payment reflects interest alone.
Why Lenders Use This Structure
Hard money serves fast-moving deals: fix-and-flips, bridge purchases, and short-term holds. Low monthly costs keep more cash in the borrower’s pocket during the project.
A flipper renovating a property needs capital for materials and labor. A small interest-only bill protects that working capital until resale.
How Interest-Only Hard Money Payments Are Calculated
The calculation is straightforward. Multiply your loan amount by the annual interest rate, then divide by 12.
Monthly payment = (Loan amount × annual rate) ÷ 12
Here is the math applied step by step:
- Take your loan amount. Example: $300,000.
- Multiply by the annual rate. $300,000 × 0.11 = $33,000.
- Divide by 12 months. $33,000 ÷ 12 = $2,750.
Your monthly cost is $2,750 for as long as the balance stays at $300,000.
Worked Examples at Different Loan Sizes
Rates on hard money commonly fall between 9% and 13%. The chart below assumes an 11% rate to show how loan size drives the monthly figure.
- $150,000 loan: $1,375 per month
- $250,000 loan: $2,292 per month
- $400,000 loan: $3,667 per month
- $600,000 loan: $5,500 per month
Notice the pattern. Double the loan, double the payment. The relationship stays linear because principal never moves.
How Rate Changes Affect the Same Loan
Rate matters as much as loan size. Here is a $300,000 loan at three different rates:
- 9% rate: $2,250 per month
- 11% rate: $2,750 per month
- 13% rate: $3,250 per month
A two-point rate difference shifts the payment by $500 monthly. Over a 12-month term, that is $6,000 in total interest.
What Can Change Your Monthly Bill Mid-Loan
Most interest-only payments stay flat, but three situations move the number.
1. Construction or Rehab Draws
Some loans fund the purchase upfront and release rehab money in stages. You only pay interest on funds released, not the full approved amount.
Example: A $400,000 loan with $100,000 held in a rehab reserve. Your first payment applies to $300,000, not $400,000.
As you draw the reserve, your balance climbs and your payment rises with it. A borrower who pulls $50,000 in month three sees the payment adjust the following cycle.
2. Interest Reserves
Some loans build several months of interest into the loan itself. The lender pays your monthly bill from that reserve.
Your out-of-pocket cost is $0 during the reserve period. Once the reserve empties, you resume paying directly.
3. Partial Principal Paydowns
If your loan allows principal prepayment, paying down the balance lowers future interest. A $50,000 paydown on a $300,000 loan at 11% cuts your monthly cost by about $458.
Check for prepayment penalties before making extra payments. Not every hard money loan permits penalty-free paydowns.
Interest-Only vs. Amortized Payments Side by Side
The difference between the two structures is large on a monthly basis.
A $300,000 loan at 11%:
- Interest-only payment: $2,750 per month, full principal due at term end
- Fully amortized over 30 years: roughly $2,857 per month, balance shrinking each month
The amortized payment looks close, but the loans behave differently. Amortized loans build equity monthly. Interest-only loans keep the balance fixed and free up cash flow.
For a six-month flip, amortization barely touches the balance. You pay slightly more each month for almost no principal reduction. Interest-only keeps the cost lean.
Planning for the Balloon Payment
The one item interest-only borrowers cannot ignore is the balloon. When the term ends, the full principal is due at once.
On a $300,000 loan, that means $300,000 due on the maturity date. Your exit plan must cover it.
Two common exits close out the loan:
- Sale: The property sells and proceeds repay the principal.
- Refinance: A conventional or DSCR loan replaces the hard money loan.
Map the exit before you close. Missing a balloon date can trigger default interest at a much higher rate.
Budgeting a Realistic Monthly Number
Build your project budget around the interest-only cost, not an amortized estimate. Add a buffer for a term extension if your project might run long.
A flipper on a 9-month loan should budget interest for 11 or 12 months. Delays in permits, materials, or resale are common on real projects.
Quick Reference: Estimating Your Own Payment
Use this shortcut for any hard money loan:
- Every $100,000 borrowed at 10% costs about $833 per month.
- Every $100,000 borrowed at 11% costs about $917 per month.
- Every $100,000 borrowed at 12% costs about $1,000 per month.
Multiply by your loan size in hundred-thousands to get a fast estimate. A $450,000 loan at 12% works out near $4,500 monthly.
Key Takeaways
Interest-only hard money payments cover borrowing costs while your principal stays fixed until a balloon payment at term end. Calculate the monthly cost by multiplying the loan amount by the rate and dividing by 12. Draw schedules, interest reserves, and principal paydowns are the main items that shift your bill.
