The Quick Read: Commitment funding is not a formal industry term, but it usually means the loan pays your interest for you through an interest reserve built into the loan. The cost is financed rather than waived, so you keep cash free during the project but owe a larger balance at payoff.
- Funding interest inside the loan protects your cash during the rehab. It raises the balance you must repay and can reduce the cash left for the work.
- Paying monthly out of pocket keeps the balance smaller. It asks you to carry the interest from your own liquidity for the whole term.
- Neither choice changes how a later DSCR refinance is underwritten. Both change your payoff balance and the cash you have left.
- Hard money terms run 6-18 months, interest-only, so the balance comes due as a balloon that a sale or refinance has to clear.
Here is the honest answer on who each option fits. Funding interest inside the loan suits an investor whose cash is better spent on the rehab, the next deal, or a contingency cushion. That investor accepts a bigger payoff in exchange. Paying monthly suits an investor with steady outside income or a liquidity pile who wants the smallest possible balance at exit. Both are legitimate. The mistake is treating a no-payments structure as free money, because someone is still paying the interest. It is you, through the loan balance.
What this loan actually costs to carry.
Hard money is sized against the project and priced by time. Enter the deal and see how much the program will lend, the cash required at closing, the carry while you hold it, and what is left at the exit.
Leverage tiers on the current program: 85% with fewer than 2, 90% with 2 or more, 93% with 5 or more completed projects — every tier capped at 75% of after-repair value. Loan amounts up to $5,000,000, larger by exception; terms of 6 to 18 months, interest-only, no prepayment penalty. The rehab portion funds in draws against completed work, not at closing.

Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. Rate, points, and months are editable assumptions. Hard money is business-purpose financing for real estate investors, not a consumer mortgage. Leverage on the current program tops out at 93% of project cost for investors with a documented track record, capped at 75% of after-repair value, with rehab funding up to 100% of the documented budget released in draws; actual terms vary by lender, borrower experience, property, and exit. Lendmire is a mortgage broker, not a lender.
A quick note on terms. Some lenders use commitment funding loosely for a reserve, a deferral, or a pre-funded interest account. Others use commitment only for the commitment letter issued at approval. Confirm which structure a term sheet describes before you compare offers.
Side-by-Side
The table below describes the two payment structures as they work on a typical hard money file. The right-hand column reflects published industry norms for interest handling, not a separate program. Details vary by lender, property, and experience, and nothing here is a commitment to lend.
| Factor | Interest Funded in the Loan | Paying Monthly Out of Pocket |
|---|---|---|
| Review basis | Deal, plan, exit, borrower experience | Same |
| Personal income docs | Typically not the focus | Typically not the focus |
| Cash at closing | Can be higher if reserve cuts the budget | Lower on this line item |
| Cash during the hold | Interest drawn from the reserve | Borrower funds each month |
| Loan balance at payoff | Larger by the reserve amount | Smaller |
| Interest on interest | Yes, on the reserve portion | No |
| If the project runs long | Reserve can run dry | Cost keeps coming from your cash |
| Property types | Non-owner-occupied 1-4 units | Same |
| Entity vesting | LLC common; guarantee often required | Same |
| Reserve expectations | Lender may still verify rehab cash | Lender verifies carry capacity |
The rows that differ are the cash rows and the balance row. Qualification, property type, and vesting do not change because of how interest is paid.
How the Two Structures Work
An interest reserve is money held back from the loan proceeds at closing. The lender uses it to pay scheduled interest while the property cannot cover its own debt service, as Re-Leased describes it. Each month, the lender draws interest from that separate account instead of billing you.
Adventures in CRE explains that the reserve is funded from the initial loan proceeds and sized from expected draws or an average balance estimate. That means the reserve is part of the loan you borrow. You repay it with the loan.
Sizing follows simple logic: monthly interest times the months of coverage. PeerSense cites typical sizing of 6 to 18 months, though that glossary leans toward commercial real estate, so treat it as a formula reference rather than a hard money rule.
Paying monthly is the plain version. The loan is interest-only, you pay the interest each month, and the principal is due at the end as a balloon. Most hard money loans do not amortize, so nothing reduces the balance along the way. The exit, a sale or a refinance, repays it.
Rehab draws are a separate line. Rehab budgets are typically held back and released in draws after completed work is inspected. A reserve funds interest. A draw funds construction. Mixing them up is how borrowers misread their closing numbers.
When Funding Interest in the Loan Is the Better Fit
The reserve route works best when cash is the scarce resource and time is reasonably predictable. Picture an investor buying a vacant duplex that needs full renovation. No rent comes in until the work finishes, and every spare dollar is earmarked for the rehab and a contingency fund. A reserve lets that investor start the project without also writing an interest check every month.
It also fits an investor running several projects at once. Liquidity spread across three jobs gets thin quickly in the sense that matters: one surprise can strain all of them. Keeping cash free for overruns can be worth more than the extra interest a larger balance costs.
Reserves are most common where income is low at closing, such as vacant or heavily renovated property, according to Hequities. That tracks with what brokers see across wholesale lenders: the less income the property produces, the more sense it makes to build the carry into the loan.
Now the costs, because a fair comparison needs them.
- The balance grows. The reserve increases the loan amount, and interest accrues on a balance that includes it. You pay interest on the money that pays your interest.
- Leverage still has caps. Across the network, fix-and-flip leverage runs 93% of project cost at 5+ completed projects, 90% at 2+, and 85% with fewer than 2, with every tier capped at 75% of after-repair value. Bridge purchases without rehab reach up to 80% of purchase price, and refinances reach up to 65% of value. All of this varies by lender, property, and experience. A reserve has to fit under those same ceilings, so a lender that builds one in may trim the rehab budget or ask for more cash at closing.
- It can run dry. If the project runs long, the reserve can be exhausted. Then you pay out of pocket, ask for an extension, or refinance. PeerSense describes the shortfall as triggering a re-cast, meaning more equity, a paydown, or an extension fee.
- A bigger payoff has to clear. The exit must repay the larger balance plus closing costs. If the appraisal comes in tight, the gap comes out of your pocket.
Size the reserve to the realistic schedule, not the optimistic one. A reserve sized to the planned term leaves no cushion if the job slips. For a fuller look at how a larger balance feeds into the next loan, see Lendmire’s piece Cash-Out Refinance Reserves After Paying Off Hard Money.
When Paying Monthly Out of Pocket Is the Better Fit
Paying monthly is the better fit when you have the liquidity and want the cleanest exit. Say you own a rental portfolio that throws off steady cash, and you are flipping one house on the side. Writing a monthly interest check barely dents your reserves, and you finish with the smallest possible payoff.
It also fits a short, well-scoped project. A cosmetic rehab with a clear scope and a contractor you trust has a narrow range of outcomes. The reserve’s insurance value is lower, and its cost, a larger balance with interest on top, buys you less.
Paying monthly gives you control too. There is no reserve to size wrong and no compounding on a financed carry. If the exit comes early, you have simply paid less interest. On the programs Lendmire places, hard money terms run 6-18 months, interest-only, with no prepayment penalty. Some lenders in the wider market set a minimum interest period, so check the term sheet either way.
The cost of this route is plain. Your cash is tied up in carry, and the monthly obligation continues until the exit, however long that takes. Lenders also commonly confirm you have the reserves to start the rehab before funding. A borrower who needs the loan to carry the interest and has little else in the bank gets a close look on that point.
An investor who pays monthly must also stress-test the schedule. If the sale slips by a few months, those extra months come from your own cash. Run the carry for a delayed exit, not only the on-time one.
What Happens at the Exit Either Way
Both paths end at the same door: a sale or a refinance. Many investors refinance out of hard money into long-term DSCR investor loans once the property is rented and stable, and Lendmire brokers that path. DSCR is monthly rent divided by the full monthly obligation, meaning principal, interest, taxes, insurance, and any HOA dues. Across the network, 1.00 is where select programs start, and stronger coverage can open better leverage and terms. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted.
How you handled interest during the bridge does not enter that test. Rent against the new payment does. What the bridge decision changes is the payoff the new loan must clear and the liquidity you have left for reserves. On a DSCR cash-out refinance, the network tops out around 75% LTV, with about 6 months of seasoning as the common expectation. Standard DSCR reserves commonly sit around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type.
One caution about the word coverage. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. For the full picture of how these loans are sized and qualified, the complete DSCR loans guide walks through each piece.
How to Decide
Run three checks before choosing.
1. Liquidity. After closing costs and the cash needed to start the rehab, how many months of interest could you carry from your own funds without stress?
2. Schedule risk. If the project runs two or three months long, which structure still works? A reserve sized to the planned term has no slack. Out-of-pocket carry keeps costing you directly.
3. Exit math. Would the exit still clear the larger payoff if the appraisal comes in light?
If the first answer is thin and the third is comfortable, funding interest inside the loan likely makes sense. If the first is strong, paying monthly usually leaves you with the smaller balance and fewer moving parts.
Watch the marketing language. A hard money loan advertised as no payments for months is typically a standard bridge or rehab loan with a reserve built in. The interest is financed, not waived. Ask the lender three questions in writing:
- Is the interest funded from loan proceeds, from my equity, or deferred to payoff?
- Does the reserve count inside the leverage caps or come out of my rehab budget?
- What happens to any unused reserve if I exit early?
Reserve, deferral, and monthly pay are three different structures. True deferral means interest accrues and is paid at payoff. A reserve is funded up front, so interest accrues from day one. Do not let the labels blur them.
Key Terms Defined
Interest reserve: A portion of the loan held in a separate account to pay scheduled interest during the project.
Commitment funding (as used here): Informal shorthand for interest paid from loan proceeds rather than by the borrower each month.
Deferred interest: Interest that accrues during the term and is paid at payoff instead of monthly.
Balloon payment: The full principal balance due at the end of an interest-only loan.
Loan-to-cost: The loan amount divided by total project cost, meaning purchase price plus rehab.
After-repair value (ARV): The estimated value of the property once renovations are complete.
DSCR: Debt service coverage ratio, meaning monthly rent divided by the full monthly obligation (PITIA).
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly cost of holding the loan.
A Balanced Verdict
Neither structure is better in the abstract. Funding interest inside the loan buys liquidity and flexibility, and you pay for it with a larger balance and interest on the reserve. Paying monthly costs you cash flow during the project, and you get a smaller payoff and a simpler loan.
The strongest files often come from investors who sized the choice to their own numbers rather than the lender’s marketing. They know their cash cushion, they plan for a delayed exit, and they have a refinance or sale that clears the payoff with room to spare.
If you are buying, rehabbing, or refinancing an investment property and want to see how the numbers work, Lendmire can help you compare hard money options based on the project, the exit plan, leverage, and your goals. Program details vary by lender, property, and experience, and nothing here is a commitment to lend.
Frequently Asked Questions
Does an interest reserve increase my loan balance?
Yes. The reserve is paid out of loan proceeds, so the balance you repay includes it. Interest accrues on that larger balance, which means you pay interest on the money that funds your interest.
What happens if the reserve runs out before I sell or refinance?
You pick up the payments out of pocket, request an extension, or refinance. Lenders often treat an exhausted reserve as a warning sign, and extensions can carry fees. Sizing the reserve for a delayed exit is the best protection.
Is commitment funding the same as deferred interest?
No. A reserve is funded at closing, so interest accrues from the first day and is paid from the reserve account. Deferred interest accrues to the back end and is paid at payoff. Ask which structure a lender means before comparing offers.
Does the way I pay interest on a hard money loan affect my DSCR refinance?
Not for approval. DSCR underwriting compares rent to the new loan’s full monthly obligation, with leverage, credit, and reserves tested separately. The bridge structure affects your payoff balance and how much cash you have left.
Can I use hard money on a property I plan to live in?
Hard money is a business-purpose product for non-owner-occupied investment property, 1-4 units, with ground-up construction up to 10 units. It is not designed for a primary residence.
