The Quick Read: There is no special “house hacker refinance” program. Refinancing out of FHA means taking a brand-new conventional loan that pays off the old one, and it gets a full underwrite. Three things decide the outcome: how the property is classified (one unit or two to four, and whether you live there), how much equity you hold, and whether rent from the other units can be documented and counted. Everything below is subject to lender guidelines and full file review, and none of it is a commitment to lend.
What a House Hacker Refinance Actually Is
A house hacker buys a one-to-four-unit home, lives in one unit, and lets tenants in the others cover part of the cost. FHA is a common starting point. The wholesale programs Lendmire places FHA loans with allow up to 96.5% financing, a 3.5% minimum investment, and a 580 decision score. Owner-occupied only, one to four units. Borrowers who want to see how the starting loan works can review Lendmire’s FHA loan programs.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, 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 new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages; Lendmire is a broker, never the lender.
The refinance question usually comes later. The FHA loan carries an upfront premium of 1.75% of the base loan, plus an annual premium that depends on term, loan amount, and LTV. On a thirty-year loan above 90% LTV, that annual premium lasts for the full term. At or below 90%, it ends after eleven years. HUD's Mortgagee Letter 2023-05 covers FHA annual premiums by LTV. Separately, HUD's announcement of the premium reduction gives March 20, 2023 as the date the reduction took effect.
Practical result: a borrower who started with a low down payment generally pays FHA insurance until the loan is paid off or refinanced. That is why house hackers look at conventional.
Key Terms Defined
Limited cash-out refinance: A conventional refinance that pays off the old loan and costs, with only a small amount of cash back to the borrower.
Cash-out refinance: A refinance where the borrower takes meaningful equity as cash, which brings a lower maximum LTV.
LTV (loan-to-value): The new loan balance divided by the appraised value.
PMI (private mortgage insurance): Insurance on a conventional loan with a smaller down payment. Unlike FHA insurance, it can come off.
Reserves: Liquid assets you still hold after closing, usually counted in months of payments.
Seasoning: How long you have owned or occupied the property before a certain refinance type is allowed.
The Step-by-Step Underwrite
Here is how a conventional lender works through a house hack refinance.
Step 1: Classify the property
The lender counts units and confirms you live in one. A conventional lender's reserve and rental-income rules turn on both. A one-unit home and a fourplex are different files, even if the borrower is the same person.
Step 2: Test the equity
The new loan is sized against the appraised value. A transaction that only pays off the FHA loan and costs generally falls into Fannie Mae's limited cash-out refinance bucket. Maximum LTV there is higher for a one-unit principal residence than for two to four units, and cash-out refinances sit lower still. Fannie Mae's Eligibility Matrix lists the limits by unit count and transaction type.
LTV also decides whether the new loan carries PMI. A very low LTV avoids it. A higher one means the new loan has cancellable insurance. Still better than FHA's lifetime version, but not free. For how PMI can come off through an appraisal versus a refinance on a two-to-four-unit home, see Lendmire's piece PMI Appraisal vs Refinance for a House Hacker's 2-4 Unit Conventional Loan.
Step 3: Document the rent
This is where house hackers get surprised. Under Fannie Mae's rental income rules, the full payment on your principal residence counts as an obligation. Lenders must also report gross monthly rent on two-to-four-unit principal residences, even if you don't use that rent to qualify. Fannie Mae publishes Form 1037, a worksheet for exactly this case.
Rent has to be supported. According to Fannie Mae's Quality Insider guidance, that means an appraiser's rent schedule (Form 1007 or 1025), or bank statements showing rent received that matches the lease, or a security deposit and first month's rent on new leases. Lenders also apply a haircut to gross rent for vacancy and upkeep, so only part of the rent counts. Informal, cash-in-a-drawer rent counts for nothing.
Step 4: Appraisal
For a two-to-four-unit property, the appraiser typically uses the Small Residential Income Property Appraisal Report (Form 1025), which supports the rent figures. For a one-unit home, the rent schedule form is 1007.
Step 5: Reserves
Fannie Mae requires six months of reserves on a two-to-four-unit principal residence transaction. A one-unit principal residence requires none, per its minimum reserve requirements. A house hacker whose cash went into the original down payment and repairs may look fine on paper and still come up short. Final terms depend on lender guidelines, property type, leverage, and the borrower's complete credit picture.
Step 6: Underwrite and close
The lender reviews credit, debt-to-income, assets, the FHA payoff, and the appraisal. The FHA upfront premium paid at origination is generally not refunded when the loan is paid off. Confirm the details with your lender.
Where the General Rule Breaks
Unit count. Reserves, LTV, and rental treatment all change between one, two, and three-to-four units. Check which bucket your property falls in before you run any math.
The FHA three-to-four-unit test goes away. FHA requires 3- and 4-unit properties to pass a self-sufficiency test showing the property's net rent covers the payment. Conventional loans have no property-level test like it. That can help a borrower who struggled with the test. But conventional replaces it with the reserve requirement and a debt-to-income review that counts your whole payment. For a deeper look at that tradeoff, see Lendmire's guide, FHA vs Conventional Loan for a House Hacker: Self-Sufficiency Test. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Moving out. FHA's occupancy rule applies at origination: you occupy within 60 days of signing and intend to stay at least one year, per HUD's owner-occupant definition. That rule is set out in HUD's Handbook 4000.1. It does not let you rent every unit and refinance as if nothing changed. A conventional lender looks at how the property is used now. If you have moved out, the lender treats it as an investment property, with lower LTV limits.
Accessory dwelling units. On a one-unit home with an ADU, Fannie Mae's Announcement SEL-2025-08 allows rent from one ADU to count on purchases and limited cash-out refinances, capped at 30% of total qualifying income. HUD has its own ADU rental income rules, so FHA and conventional treat the same unit differently.
Taking cash out. Real cash out moves you into a stricter bucket with lower maximum LTV. The same announcement also raised the cash back allowed on limited cash-out refinances, so the line between the two buckets is worth checking with your lender.
Older FHA loans. Loans with case numbers from before mid-2013 followed different insurance cancellation rules. Ask HUD or your servicer rather than assuming.
FHA Insurance vs. Conventional PMI
| Factor | FHA | Conventional |
|---|---|---|
| Insurance type | Upfront plus annual premium | PMI, if LTV is high |
| Duration | 11 years or full term, by LTV | Cancellable |
| Cancellation | Not on request | On request at 80%, automatic at 78% |
| Governed by | HUD schedule | Federal PMI rules |
The CFPB explains that PMI can be cancelled on request at 80% of original value, must end automatically at 78% if you are current, and ends at the loan's midpoint. The request goes in writing, with a good payment history and no junior liens. The lender may ask for evidence your value has not fallen. That structural difference is the real prize. FHA insurance on a high-LTV loan stays; PMI eventually leaves.
A Scenario in Percentages
Picture a borrower who bought a duplex with the minimum 3.5% investment and has lived in one unit since. Their balance is now meaningfully lower and the home has appreciated. A new appraisal puts the new loan at a modest LTV, with room to spare under conventional limits for two units.
What decides it from here? Documented leases on the other unit. Six months of reserves left after closing. A credit profile and debt-to-income that hold up with the full housing payment counted and only part of the rent offsetting it. Pass those, and the conventional loan can drop FHA insurance. Miss the reserves, and the file stalls even with strong equity.
The flip: the same borrower with thin equity might land in PMI territory on the new loan. Savings then depend on the new loan's pricing and costs against the FHA insurance still remaining. For a borrower within a few years of leaving the home, the break-even may never arrive.
Decision Table: Stay, Streamline, or Convert
| Your situation | Likely path |
|---|---|
| Strong equity, documented rent, reserves in place | Conventional limited cash-out |
| Want to keep FHA, lower cost only | FHA Streamline |
| Low equity, thin reserves | Wait, or pay down first |
| Already moved out and renting all units | Different (investment) category |
An FHA Streamline refinances an existing FHA loan with no appraisal, a limited credit review, and a net tangible benefit. The premium continues, so it cannot remove FHA insurance. A conventional refinance is a full new underwrite. Some borrowers want the Streamline's lighter paperwork; others want out of FHA insurance. They are not the same goal.
An FHA rate-and-term refinance with an appraisal reaches 97.75% on a principal residence occupied for the previous twelve months. FHA cash-out reaches 80% LTV on a home owned and occupied for 12 months before the case number. Both keep you in FHA. Terms depend on the lender's guidelines, the property type, the leverage, and a full review of the credit profile.
Common Mistakes and Denial Triggers
- Assuming you can cancel FHA insurance at 20% equity. Not on a loan above 90% LTV at origination.
- Treating FHA insurance like PMI. They follow different rules.
- Counting all the rent. Lenders apply a haircut and require documentation.
- Skipping reserves. Six months on a two-to-four-unit home is a hard line.
- Informal leases. Verbal agreements and undocumented rent don't count.
- Assuming "conventional is always cheaper." It depends on equity, credit, unit count, reserves, and costs. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Some legislation has been discussed that would change FHA premium cancellation, but nothing here should be treated as current law.
Frequently Asked Questions
Can I refinance a house hack from FHA to conventional?
Yes, if the new loan is reviewed on its own. The lender classifies the property by unit count and occupancy, sizes the loan against a new appraisal, and reviews credit, income, reserves, and documented rent. Subject to lender guidelines and full file review.
Does the rent from my other units count as income?
Partly, and only when documented. Lenders count a portion of gross rent after a haircut for vacancy and upkeep, supported by leases, an appraiser's rent schedule, or bank statements. Rent you can't document won't help you qualify.
Do I need reserves for a conventional refinance on a duplex?
Usually yes. Fannie Mae requires six months of reserves on a two-to-four-unit principal residence and none on a one-unit. Reserves are liquid assets left after closing, and some asset types are not accepted.
What if I have already moved out?
A conventional lender then treats the property as an investment, not a primary residence. LTV limits are lower and the file is a different, harder category. Occupancy at refinance is judged on current use, not on the original FHA rule.
Is a Streamline the same as refinancing to conventional?
No. A Streamline keeps you in FHA, with no appraisal and a limited credit review, and the premium continues. A conventional refinance is a full new underwrite that can end FHA insurance.
If you are weighing a refinance and want the break-even run on your own numbers, Lendmire can compare the programs on the same home.
