The Quick Read: Usually not: a hard money loan is sized on the property’s value, the project cost, and your exit plan rather than on rent, so ADU rent rarely changes the loan amount, though it matters later when you refinance into a long-term rental loan, where an appraiser’s market-rent opinion on a legal, supportable ADU can count toward coverage. Hard money asks whether the asset and the plan can repay the loan. A DSCR lender asks whether the rent can carry the payment. Your ADU plays a different role in each.
- Hard money leverage is tested against value and cost, so an ADU helps only through the as-is value or after-repair value an appraiser will support.
- ADU rent becomes a test at the DSCR exit, and the appraiser’s market rent counts, not your own projection.
- A vacant, newly built, or unpermitted ADU can leave the rent unusable, so back-solve the exit without it.
- Agency rules for owner-occupants do not govern hard money or DSCR files.
Key Terms Defined
ADU (accessory dwelling unit): a separate living space on the same lot as a main home. It can be detached, attached, or converted from a garage or basement.
Hard money loan: short-term, asset-based financing for investment property. It is sized on value, project cost, and exit rather than on rent coverage.
ARV (after-repair value): the value an appraiser supports once the planned work is finished.
DSCR (debt service coverage ratio): a rental loan test that divides the property’s rent by its full monthly obligation.
PITIA: principal, interest, taxes, insurance, and any association dues. This is the payment the rent has to cover.
Market rent: the appraiser’s opinion of what the unit would rent for, built from comparable rentals.
Exit: the plan for repaying a short-term loan, either by selling or by refinancing.
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.

Cost cap sets the loan · positive spread
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.
How Does Hard Money Underwriting Treat Rent?
Hard money underwriting runs on value first, exit second, and the borrower third. Rent is not the lever. Nav’s investor explainer makes the same point: these loans are underwritten on the property and its after-repair value rather than on income, credit score, or debt-to-income.
Here is how that works on the files Lendmire places through its wholesale network. The lender orders a valuation, either an as-is value or an ARV on a rehab deal. Leverage is then tested against that value and against total project cost, alongside your track record and reserves.
The typical structure looks like this. Fix-and-flip leverage runs 93% of project cost at five or more completed projects, 90% of project cost at two or more, and 85% with fewer than two. Every tier is capped at 75% of after-repair value. A bridge purchase without rehab goes up to 80% of purchase price. A cash-out or rate-and-term refinance goes up to 65% of value.
Terms run six to eighteen months, interest-only. These figures vary by lender, property, and experience, and nothing here is a commitment to lend.
No line in that list says rent. A tenant in the ADU does not raise your leverage or shrink your down payment. The top tiers go to experienced investors, and a first-time investor sits in the lower tiers whether the ADU is rented or not.
Where ADU Rent Still Matters on a Hard Money Deal
Rent matters in three places even though it does not size the loan: carry, reserves, and the exit story.
Carry. Hard money is interest-only, and you pay it while you hold the property. Rent from an existing, leased ADU can help you service that interest. It does not change what the lender will advance.
Reserves. A lender looking at your file wants to see that you can survive a slow stretch. Rent offsets some of that risk, but most lenders weigh it as support, not as qualifying income.
The exit. This is the big one. Many investors refinance out of hard money into long-term DSCR financing once the property is stabilized, and Lendmire brokers that path. Lendmire’s piece Hard Money Exit Loans: How the Payoff Is Sized on the Appraisal and the Rent walks through that handoff in detail. The short version is that the exit loan is the first place your ADU rent faces a real test.
ADU Value vs. ADU Rent
An ADU can help a hard money deal through value, and it can do that without its rent entering the calculation. An ADU may support a higher appraised value, depending on comps and underwriter review. It also may not.
Here is why the result is uncertain. Appraisers build value from comparable sales. A house with a legal, permitted ADU is hard to comp because few nearby sales share that feature. When no close match exists, the appraiser may give the unit little credit. Investors often report that ADUs appraise below what they cost to build, so you should not assume the build cost transfers into value.
This matters for sizing because hard money leverage is tested against value. If you plan to buy a house, build an ADU, and borrow against the finished value, your ARV assumption carries real risk. The lender and the appraiser decide what the ADU is worth, not you.
A related point: a house with one ADU is not appraised like a duplex. Property-type classification can change how the appraiser approaches the file, and it affects which comps are usable.
What Does Each Lender Type Do With ADU Status?
This table sums up how the usual ADU situations play out. Treatment varies by lender and program, so read the cells as typical patterns rather than promises.
| ADU status | Hard money loan | DSCR exit loan |
|---|---|---|
| Existing and leased | Value support; rent helps carry | Appraiser’s market rent counts if legal |
| Existing and vacant | Value support only | Market rent supports income, no lease needed |
| Under construction | Value and plan, funded in draws | No rent until finished and appraised |
| Planned only | Enters via ARV if supportable | Not counted until built |
| Unpermitted | Value likely excluded or reduced | Rent likely excluded |
The pattern is consistent. Hard money looks at the unit as part of the asset’s value. DSCR looks at it as a source of rent, and only if the unit is real and lawful.
Planned, Vacant, and Unpermitted ADUs
A planned ADU. If the ADU does not exist yet, it contributes nothing to rent coverage today. It enters the hard money file only through the ARV the appraiser is willing to support. For builds, Lendmire’s piece How a DSCR Lender Takes Out Hard Money Ground-Up and ADU Builds covers the takeout side. On the hard money side, ground-up construction runs up to 90% of cost and 75% of completed value at three or more completed projects. Up to 100% of the rehab budget can fund in draws against completed work, and that figure applies to the rehab budget only, never to purchase leverage.
A vacant ADU. A new or empty unit has no lease history. At the DSCR exit, the appraiser’s market-rent opinion supports the income. You do not need a signed lease to have the unit considered, though documentation requirements vary by program.
An unpermitted ADU. Treat this as the high-risk case. The appraiser will likely flag the unit and leave it out of both value and rental income. If the rent does not count, your coverage ratio has to work without it. A permit check before you buy protects both the value and the income.
More than one ADU. Treatment is program-specific. Ask the lender how many units it will count before you build the plan around the second one.
Short-term rental use. Rent from an ADU used as a short-term rental is documented differently from long-term rent.
How the DSCR Exit Counts ADU Rent
At the exit, the new lender runs its own appraisal and its own test. Lendmire’s complete DSCR loans guide covers the basics. Here is the short version for this question.
A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender divides monthly rent by PITIA. If rent is 1.20 times the payment, the coverage ratio is 1.20x.
Two gates apply on a hard money exit. The value test asks whether the new appraisal supports the payoff. The rent test asks whether the rent covers the new payment. Clearing one gate does not clear the other. A strong ARV with a weak rent number can still leave you short.
Whose rent counts. The appraiser’s market rent counts, not your pro forma. The appraiser finds comparable rentals, adjusts them, and gives an opinion of market rent. That opinion is the gross rent the underwriter uses. The appraiser reports it on a rent schedule or in the rental-information section of the appraisal. The forms trace back to the agency world: Fannie Mae’s Selling Guide names Form 1007 for single-family rent schedules and Form 1025 for two-to-four-unit income properties. DSCR programs borrow those forms and set their own rules.
What coverage you need. Across the wholesale network, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. No-ratio loans are available only through select lenders, generally for borrowers who already own a primary residence. Stronger coverage opens better pricing and leverage.
What else the lender checks. Most programs want a credit score around 660, with a 620 floor in parts of the network and 700 or higher unlocking the strongest leverage tiers. Purchase files usually land at 75% to 80% LTV on an investment property, and cash-out refinances top out around 75% LTV. About six months of seasoning is the common expectation on a cash-out. Reserves vary by lender, leverage, loan size, and transaction type, commonly around six months of PITIA.
Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
Worked Example: Stress-Testing the ADU Rent
These are modeled assumptions, not market data. Picture a house with a rented ADU on the back of the lot, financed with a hard money bridge and headed for a DSCR exit.
Run the first case with the ADU rent included. Say the appraiser credits both the main house and the ADU, and the combined market rent covers the new payment at roughly 1.25x. That clears the 1.00 mark many select programs use, with room to spare.
Run the second case with the ADU excluded. The appraiser decides the unit is not legal or not supportable. Now only the main house rent counts, and coverage drops to roughly 0.95x. That is below the 1.00 start point many select programs use.
Several outcomes are possible from there. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. You could also add cash to reduce the loan size, or choose an interest-only structure through a select lender, both subject to lender review. A no-ratio path exists through select lenders, generally for borrowers who already own a primary residence. None of these is automatic, and qualification stays subject to credit approval, property review, and lender guidelines.
The third case is a vacant or delayed ADU. Coverage depends on the appraiser’s market rent rather than a lease, but your hard money carry runs longer while you lease up. Interest-only payments keep coming even when the unit sits empty.
The practical rule is to back-solve the exit before you take the bridge loan. Model it with a conservative appraisal and no ADU income. If the deal works that way, the ADU is upside. If it only works with the ADU, you are depending on one appraiser’s opinion of one small unit.
Agency Rules Are a Different Game
You may see headlines about ADU income now counting toward mortgage approval. That is a real rule, but it is not your rule. Fannie Mae’s announcement on ADU income applies to a one-unit principal residence, allows income from one ADU only, and caps it at 30% of total qualifying income. It is built for owner-occupants.
HUD’s guidance for FHA loans is similar in spirit: a one-unit property with a single ADU remains a one-unit property. That is an FHA classification rule. Neither document sets terms for hard money or DSCR loans, so do not carry the 30% cap or the one-ADU limit into an investor file.
The Timeline From Bridge Loan to Permanent Loan
The sequence below shows when rent starts to count.
1. Acquire or build. The hard money loan funds against value, project cost, and your exit plan.
2. Finish and permit. Confirm the ADU is legal and complete, since a unit the appraiser cannot credit cannot help your exit.
3. Lease up or document rent. A lease is useful support, though the appraiser’s market rent drives the DSCR number.
4. Season. The clock on a cash-out refinance typically runs from the recorded title date, and about six months is the common expectation.
5. Refinance. The DSCR lender orders its own appraisal, tests value and rent, and sizes the payoff.
Tax treatment varies; consult a qualified professional.
Questions to Ask Before You Commit
- Will the lender count the ADU in value, in rent, or in both?
- Does the program require a lease, or does the appraiser’s market rent satisfy the income test?
- How many ADUs will the program credit?
- What leverage and reserves apply at the exit, and what coverage ratio is the floor?
- What happens to the exit if the appraiser excludes the ADU?
Frequently Asked Questions
Does a vacant ADU help on a hard money loan?
Only through value. A vacant unit has no rent to offset your carry, and the lender does not size the loan on projected rent. At the DSCR exit, a vacant ADU can still support income through the appraiser’s market-rent opinion if the unit is legal.
Can an unpermitted ADU count?
Unlikely. The appraiser will probably flag the unit and leave it out of value and rental income. Plan the exit as if the ADU does not exist, and treat legalization as upside.
Does the ADU raise my ARV?
It may support a higher appraised value, depending on comps and underwriter review. Because few nearby sales share the feature, appraisers sometimes credit the unit at less than it cost to build. Use a conservative ARV when you size the deal.
Can I use short-term rental income from an ADU?
Possibly at the DSCR exit, though documentation differs from long-term rent and programs have their own hosting-history rules.
When does the ADU rent start to matter?
At the exit. Hard money sizes on value and plan, while the DSCR refinance tests whether the appraiser’s market rent covers the new payment. That is the moment to know whether the unit is legal, complete, and supportable.
