The Quick Read: Usually, projected rent from part of your own home will not count toward qualifying on a standard cash-out refinance. Agency rules treat rent from your principal residence as ineligible income, with narrow exceptions for boarders and a legal accessory dwelling unit (ADU). Even those exceptions mostly sit on purchase and limited cash-out loans, so the loan type decides whether the rent helps.
Key Takeaways
- A standard cash-out on a one-unit primary residence is generally underwritten on your income, not on rent from a room or basement.
- Fannie Mae and Freddie Mac allow ADU rent only on a purchase or a limited or no cash-out refinance, with a 30% cap on qualifying income.
- A legal ADU needs a kitchen, a bathroom, and a separate entrance. A rented bedroom is not an ADU.
- FHA Streamline and VA IRRRL loans are not cash-out products, so rent is not the deciding factor.
- If rent is what makes your ratios work, the structure may need to change, not the paperwork.
What Does “Projected Rent” Mean on Your Own Home?
Projected rent is the rent an appraiser or lender estimates a space could earn, as opposed to rent you have already collected under a lease. On a home you live in, that space is a basement apartment, a detached unit, or a room.

Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included.

Here is the part most borrowers miss. For an owner-occupied home, the rent is not treated like rent from a rental property. The Fannie Mae Selling Guide’s rental income topic says rental income from a principal residence generally can’t be used to qualify. Two exceptions exist: boarder income and rental income from an ADU. Fannie Mae has since reorganized that topic, so older pages cite one section number and newer ones cite another. The rule is the same either way.
Across the wholesale programs Lendmire places files with, this is the first thing sorted on any refinance where the borrower mentions a tenant. The question is never “how much rent do you get.” It is “what kind of space is it, and what loan are you asking for.”
How Is a Cash-Out Refinance Underwritten, Step by Step?
A cash-out refinance is underwritten on the borrower’s income, credit, and the equity in the home. Rent counts only if the loan type and the space both allow it. Here is the sequence a file follows.
1. Classify the space. Is it a legal ADU, a roommate or boarder in the house, or a room? Freddie Mac defines an ADU as a living area independent of the main dwelling, with at least a kitchen, a bathroom, and a separate entrance, per its ADU guide FAQ.
2. Pick the loan purpose. Standard cash-out, limited cash-out, or no cash-out. This one choice decides whether ADU rent can be used at all.
3. Document the rent. An ADU needs evidence: a lease, rent history, and an appraiser’s rent estimate. Fannie Mae accepts the single-family comparable rent schedule when the appraiser explains it covers an ADU on a one-unit principal residence.
4. Calculate what counts. Counted rent is less than collected rent. Fannie Mae’s ADU and boarder flyer applies a 25% vacancy and loss reduction, then caps the result at 30% of total qualifying income. Freddie Mac limits the lease-documented amount to 75% of the lease and also caps ADU rent at 30% of income, per its ADU fact sheet.
5. Appraise and underwrite. The appraiser looks at zoning and comparable sales. The ADU must be legal, legal non-conforming, or in an area with no zoning. Rent from an illegal ADU can’t be used.
6. Run the ratios. Automated findings govern most files, and the wholesale conventional programs set a total ratio ceiling of 50% on those approvals. A loan that is manually underwritten is held to a ratio of 36% or 45% instead, with the reserve and score factors of the Eligibility Matrix deciding which applies.
Where Does ADU Rent Actually Work?
ADU rent works on a purchase or a no cash-out refinance, and Fannie Mae also allows it on a limited cash-out refinance. It does not work on a standard cash-out at either agency. Fannie Mae limits ADU rent to purchase or limited cash-out refinances on one existing ADU. Freddie Mac allows it on a purchase or a “no cash-out” refinance of a one-unit primary residence, per Guide section 5306.1.
Financing the property and counting its rent are separate questions. Freddie Mac’s fact sheet says a property with an ADU can itself be financed by cash-out, no cash-out, or purchase. What changes is whether the ADU rent can be used as income. A borrower with strong income can take cash out on a home with an ADU and never need the rent. A borrower who needs the rent to pass the ratio is the one who hits the wall.
| Space | Counts as income? | Notes |
|---|---|---|
| Legal ADU | Sometimes | Not on standard cash-out; 30% cap |
| Boarder in the house | Sometimes | Documented history; 30% cap |
| Room rented to a roommate | Generally no | Principal residence rule applies |
| Unit in a 2–4 unit home | Often, other units | Different path than a one-unit home |
Which Path Fits Which Situation?
| Path | Cash back? | Rent helps? |
|---|---|---|
| Standard cash-out | Yes, to 80% LTV on a one-unit primary | Generally no |
| Limited cash-out (rate-and-term) | Incidental only | ADU rent may help |
| FHA Streamline / VA IRRRL | No meaningful cash | Not the deciding factor |
| Home equity loan or line | Yes | Depends on that lender |
Limited cash-out is the only refinance lane where ADU rent can help and a new loan still replaces the old one. Cash back there is incidental. Fannie Mae sets the limit at the lesser of 2% of the new loan amount or $2,000, while Freddie Mac sets it at the greater of 1% of the new loan amount or $2,000. Both figures are subject to lender guidelines and full file review.
Where the General Rule Breaks
Several edge cases change the answer.
Boarder income. Fannie Mae treats boarder income as generally ineligible but allowable in some instances. It can make up to 30% of qualifying income, and the worked example divides documented rent from the prior 12 months by 12. A boarder rents space inside your dwelling.
Rented ADU while you live in it. According to Freddie Mac, rent from the main one-unit dwelling can’t be used if the borrower lives in the ADU. The property is still a primary residence.
Two- to four-unit primary residence. Rent from the units you don’t occupy can count, but Fannie Mae’s ADU page says ADUs aren’t eligible with a two- to four-unit dwelling. These are two different paths. Leverage also differs: a standard cash-out reaches 80% on a one-unit primary residence and 75% on a two- to four-unit.
Multiple ADUs or a manufactured home. Fannie Mae makes properties with multiple ADUs ineligible and excludes ADUs where a manufactured home is the primary residence.
Unpermitted space. The basement apartment with no permit is the most common failure. If the unit is illegal, the rent can’t be used, and the appraiser may not count the space as living area.
Short-term rental. Fannie Mae’s most recent restructuring added policy on short-term rental income with alternative documentation. Treat that as a separate topic. Ask before assuming it applies to your home.
Property management experience. Fannie Mae’s general rule is that positive rental income needs 12 months of property management experience. Otherwise rent can only offset the housing payment. Operators see this one trip up first-time landlords who planned to count every dollar.
The Seasoning Rules Apply Regardless of Rent
Rent aside, a cash-out refinance has its own timing gates. The first mortgage being paid off must be at least 12 months old, measured note date to note date, per Fannie Mae’s cash-out eligibility update. At least one borrower must also have been on title for six months, with exceptions for delayed financing, inheritance, and legal awards. The wholesale lane that reaches 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio has its own six months of seasoning, and it applies to a primary residence with a conforming balance on a thirty-year fixed. In Texas, a cash-out on a homestead is capped at 80% of the home’s value by the state constitution, and that wholesale lane is not written there. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A borrower who bought the home last spring and just finished the basement can have a perfect rent story and still be ineligible for cash-out. The loan age and title time come first.
What About FHA Streamline and VA IRRRL?
Neither is a way to take cash out. The FHA Streamline refinances an existing FHA loan with limited credit review and a net tangible benefit, and it has no meaningful cash back. The VA IRRRL refinances an existing VA loan, carries a 0.5% funding fee unless exempt, needs no VA appraisal, and requires a net tangible benefit and seasoning of the later of 210 days and six payments. A VA cash-out, by contrast, can pay off other liens, provide cash, and requires an appraisal.
Rent from a room or unit is mostly irrelevant to both. If you need cash and hold a VA loan, the VA cash-out is the product to compare, not the IRRRL.
What Documents Should You Gather?
For a file where rent is part of the story, gather these before applying:
- Current lease or written boarder agreement
- Twelve months of rent receipts or deposits, if rent history exists
- Proof the space is legal: permit, certificate of occupancy, or zoning confirmation
- Photos and a floor plan showing the kitchen, bathroom, and separate entrance
- Your last two years of income documents, since your own income carries the loan
An appraiser’s rent estimate, not your asking rent, is what the lender weighs when there is no history. Overstated rent is a common mistake. It also creates misrepresentation risk. Occupancy and rent have to be disclosed as they are, because the lender relies on them and the CFPB’s ability-to-repay explainer says lenders must document the income, assets, and expenses they rely on.
When Projected Rent Isn’t Enough
If the rent is what makes your ratios work and the loan type won’t count it, you have four options.
- Switch to limited cash-out. You get only incidental cash, but ADU rent may help the ratio.
- Wait and build history. Twelve months of documented rent or property management experience can change how the income is treated.
- Reduce the debt side. Paying off a consumer debt can move the ratio more than rent would.
- Compare a home equity loan or line. That is a second lien, underwritten by a different lender on its own rules, and it leaves your first mortgage in place.
Mortgage insurance matters too. It is required above 80% LTV on the agency path, with the wholesale no-MI cash-out lane as the exception. Cash-out on a one-unit primary residence stops at 80%, so insurance rarely enters that picture, but it does on a limited cash-out at 95%. It cancels on request at 80% of original value with good payment history, and it ends automatically at 78%. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Key Terms Defined
Accessory dwelling unit (ADU): A separate living space on the property with its own kitchen, bathroom, and entrance.
Boarder: A person who rents space inside your own dwelling, which is different from a tenant in a separate unit.
Limited cash-out refinance: A refinance that pays off the existing first mortgage and costs, with only small cash back.
Seasoning: The minimum time you have held the loan or the title before a cash-out is allowed.
Qualifying income: Income a lender is allowed to count after caps and haircuts, which is less than the income you receive.
Frequently Asked Questions
Can I use rent from a spare room to qualify for a cash-out refinance?
Generally no. Agency rules treat rent from your principal residence as ineligible, with exceptions for boarders and a legal ADU. A roommate in a bedroom usually does not fit either, and standard cash-out excludes ADU rent anyway.
Does ADU rent count on a standard cash-out refinance?
No, at both Fannie Mae and Freddie Mac. ADU rent is limited to purchase and limited or no cash-out refinances, and it is capped at 30% of qualifying income. Underwriting support for it rolled out in stages, so a given lender may not accept it.
Is a basement apartment automatically an ADU?
No. An ADU needs a kitchen, a bathroom, and a separate entrance, and it must be legal under local zoning. An unpermitted apartment can’t generate usable rent.
Can an FHA Streamline or VA IRRRL give me cash?
No. Both are built around no meaningful cash back and do not turn on rent. A VA cash-out is a separate product with an appraisal.
Does renting part of my home change it from a primary residence?
Not by itself. Freddie Mac says the home stays a primary residence when the borrower lives in the ADU, and a tenant in a separate unit doesn’t reclassify it. Occupancy still has to be disclosed accurately, because it sets leverage.
