How to Turn Your Primary Residence Into a Rental Property

To turn your primary residence into a rental property, you need to confirm your mortgage allows it, check your HOA and local zoning, switch from a homeowners policy to a landlord policy, understand how the IRS will treat the property once tenants move in, get whatever rental permit your city requires, and follow fair housing rules from your first ad forward. Skip any one of those steps and you can lose money, coverage, or the right to rent at all.

The single biggest financial trap sits inside the tax code. Section 121 of the Internal Revenue Code lets you exclude up to $250,000 of capital gains ($500,000 for married couples filing jointly) when you sell a primary residence, but only if you owned and lived in the home for two of the five years before the sale.¹ The day you move out, that five-year clock starts. Everything below assumes you’re aware of it.

Check Your Mortgage First

Most conventional mortgages backed by Fannie Mae or Freddie Mac require you to move into the property within 60 days of closing and live there as your primary residence for at least one year. FHA, VA, and USDA loans carry similar or stricter occupancy periods. These rules live inside your loan documents rather than in a single federal statute, so pull out your closing paperwork and read them.

Moving out before that initial occupancy period expires without telling your lender can be treated as a breach of contract, and in some cases as occupancy fraud. Even after you satisfy the required period, some loan agreements contain clauses letting the lender call the full balance due if the property’s use changes. Lenders rarely exercise that right when you’ve lived there the required time, your payments are current, and you notify them proactively. Make the call anyway. If the current loan terms don’t work for a rental, the lender may modify the loan, or you can refinance into an investment property mortgage at a somewhat higher rate.

HOA Rules and Local Zoning

If your home is in a community with a homeowners association, read the covenants before you list. Many HOAs cap the percentage of units that can be leased at any time, ban short-term rentals outright, or require minimum lease terms of six months or longer. Violations can trigger daily fines, and some associations can place a lien on your property for unpaid penalties.

Zoning matters separately. Some municipalities restrict rental activity in single-family residential zones, particularly for short-term or vacation rentals. Confirm your property’s zoning with the local planning department. Zoning violations can lead to cease-and-desist orders and daily civil penalties. A call or an online search through the city’s zoning map usually settles it in minutes.

Switch Your Insurance Before the First Tenant Moves In

A standard homeowners policy (the HO-3 form) explicitly excludes coverage for business activities, and renting to tenants counts.² If a tenant or guest is injured on the property while your homeowners policy is still in place, the insurer will likely deny the claim. You need a landlord policy (often written on a DP-3 dwelling fire form), which covers the structure, liability for tenant injuries, and lost rental income if a covered event makes the property uninhabitable.

Expect a higher premium than you paid as an owner-occupant. The exact increase depends on location, property condition, and coverage limits. A gap of even a single day between the two policies leaves you exposed, so line up the landlord policy to take effect on or before the tenant’s move-in date.

Understand the Tax Consequences

Converting the property changes its tax character. Depreciation, the Section 121 clock, and passive loss limits all start behaving in ways they didn’t when you lived there.

Depreciation and Your Starting Basis

Once the property is placed in service as a rental, you depreciate the building (not the land) over 27.5 years using the straight-line method under the Modified Accelerated Cost Recovery System. Your starting basis for depreciation is the lesser of the property’s fair market value on the conversion date, or your adjusted basis, meaning what you originally paid plus improvements, minus any casualty loss deductions.³

Say you bought for $300,000, added $50,000 in improvements (adjusted basis of $350,000), and the home is now worth $500,000. Your depreciation basis is $350,000, not $500,000. You only depreciate the building portion, so subtract the land value, often estimated by your county assessor at 15 to 20 percent of total value. Get an appraisal on the conversion date to establish fair market value and the land-to-building split. You’ll want that documentation if the IRS ever asks.

The Five-Year Section 121 Clock

Once the property becomes a rental, you have to sell within the five-year window to still meet the two-out-of-five-year residence test and claim the exclusion. Wait too long and you lose it entirely.

Two additional catches apply even if you sell in time. First, any gain attributable to depreciation you claimed (or should have claimed) after May 6, 1997, cannot be excluded under Section 121 regardless of the residence test.¹ That depreciation recapture is taxed at a maximum rate of 25 percent.⁴ Depreciate $40,000 over four years of rental use, sell, and you owe up to $10,000 in recapture tax on that piece, even if the rest of your gain qualifies for exclusion.

Second, periods after 2008 when the property was not your main home count as “nonqualified use,” and the gain allocated to those periods doesn’t qualify for exclusion either.¹ There’s an exception: nonqualified use occurring after the last date the property was your main home doesn’t reduce the exclusion.⁵ In plain terms, if you lived there first and rented afterward, the rental period at the end generally won’t cut into your exclusion, as long as you sell inside the five-year window. But if you rented first and moved in later, those early rental years would.

Passive Activity Loss Limits

The IRS classifies rental real estate as a passive activity. If rental expenses exceed rental income and you have a loss, you generally can’t use it to offset wages, salary, or other nonpassive income. One important exception: if you actively participate in managing the rental (deciding on tenants, repairs, and lease terms), you can deduct up to $25,000 of passive rental losses against other income.⁶

That $25,000 allowance phases out once your modified adjusted gross income tops $100,000 and disappears completely at $150,000.⁶ Married-filing-separately taxpayers who lived with their spouse at any point during the year get no special allowance. Losses you can’t deduct in a given year carry forward, so they’re not lost.

Homestead Exemption Goes Away

Most states offer a homestead exemption that reduces the taxable value of a primary residence. When you convert to a rental, you lose it, and your property tax bill goes up accordingly. In areas with generous homestead benefits, the jump can be several thousand dollars a year. You’re generally required to notify your county assessor’s office of the change. Some jurisdictions catch it automatically when you file rental income or apply for a rental license; don’t count on that. Failing to report the change can result in penalties for claiming an exemption you no longer qualify for.

Keep Receipts from Day One

The IRS expects documentation for every deductible expense: receipts, canceled checks, bills.⁷ Common deductibles include mortgage interest, property taxes, insurance premiums, repairs, management fees, and advertising. A separate bank account for rental income and expenses saves hours at tax time. New landlords lose the most money by starting sloppy and trying to reconstruct records later.

Get Your Local Rental Permit

Most cities and counties require some form of rental registration, business license, or certificate of occupancy before you can legally rent out a home. Requirements vary widely. Some jurisdictions want nothing more than a basic registration form. Others require a full habitability inspection before issuing a permit. Ask your local building department or municipal clerk’s office what applies to you.

Applications commonly ask for the property’s parcel number (on your tax assessment or deed), number of bedrooms, total square footage, and contact information for you or a local property manager who can respond to emergencies. Some jurisdictions require the emergency contact to live within a set distance of the property. Fees run from under $50 to several hundred dollars. If an inspection is required, expect to wait two to four weeks. An inspector will check fire, safety, and building code compliance, including smoke detectors, safe wiring, functional plumbing, and adequate heating. Pass the inspection and the permit or certificate of occupancy usually arrives within a few business days.

Smoke and Carbon Monoxide Detectors

Virtually every jurisdiction requires working smoke detectors in rental properties, and rules for rentals are often stricter than what applied when you occupied the home yourself. Detectors are generally required in each bedroom, in the hallway outside sleeping areas, and on every level. Carbon monoxide detectors are commonly required if the home has fuel-burning appliances, an attached garage, or a fireplace. Many jurisdictions require hardwired units with battery backup rather than battery-only. Handle this before the inspection.

Lead Paint Disclosure for Pre-1978 Homes

If your home was built before 1978, federal law requires you to disclose known lead-based paint hazards to tenants before they sign a lease. You must provide an EPA-approved pamphlet called “Protect Your Family From Lead in Your Home,” disclose any known lead paint or hazards, and share any inspection reports or records you have.⁸ The lease itself must include a specific lead warning statement and a signed tenant acknowledgment.

You aren’t required to hire an inspector or test for lead paint. The obligation is to disclose what you know. But existing reports must be shared. The inflation-adjusted civil penalty currently reaches up to $21,699 per violation under the Residential Lead-Based Paint Hazard Reduction Act.⁹ Each lease you fail to disclose on is a separate violation.

Fair Housing Applies from Your First Ad

Once you become a landlord, the Fair Housing Act governs how you advertise, screen, and select tenants. It prohibits discrimination based on race, color, religion, sex, familial status, national origin, or disability.¹⁰ Many state and local laws add protected categories such as sexual orientation, source of income, or age. Penalties can reach tens of thousands of dollars per incident, and tenants can sue in federal court.

Fair housing applies to advertising. Phrases like “no kids,” “English speakers preferred,” or “ideal for young professionals” can each be read as expressing a preference based on a protected class. Keep listings focused on the property: bedrooms, rent, pet policy, lease length.

Screening Applicants

If you use a third-party service to pull credit or background reports, the Fair Credit Reporting Act imposes specific obligations. Before pulling a report, certify to the reporting company that you’re using it for housing purposes only. If you deny an applicant based partly or entirely on the report, provide an adverse action notice with the reporting agency’s name and contact information, a statement that the agency didn’t make the decision, and notice of the applicant’s right to dispute inaccuracies and get a free copy of the report within 60 days.¹¹

Criminal history screening deserves particular care. HUD guidance warns that blanket policies rejecting anyone with any criminal record can create Fair Housing Act liability where the policy has a disproportionate impact on minority applicants. Common practice is to screen only on convictions rather than arrests, limit the lookback to seven to ten years, focus on offenses that pose an actual threat to property or residents, and give applicants a chance to explain their circumstances.

Security Deposits and Lease Terms

Every state regulates security deposits differently. Caps range from one month’s rent to no statutory limit, with most states between one and two months. Some states allow higher deposits for furnished units or tenants with pets. States also regulate how you hold the deposit (some require a separate escrow account), how quickly you must return it after move-out, and what deductions are allowed. Security deposit disputes are among the most common landlord-tenant lawsuits, and courts frequently hit landlords who break deposit rules with statutory damages of two or three times the deposit.

Late fees deserve the same attention. Roughly two-thirds of states have no statutory cap, but fees must be reasonable and spelled out in the lease to be enforceable. Where caps exist, they typically run between 5 and 10 percent of monthly rent. An unreasonable fee, even in a no-cap state, gives the tenant grounds to challenge it.

The Sequence That Keeps You Covered

Order matters. Doing these steps out of sequence creates gaps in coverage or compliance.

Confirm your mortgage allows the conversion.
Check HOA covenants and local zoning.
Get an appraisal on the conversion date to establish fair market value and the land-to-building split for depreciation.
Switch to a landlord insurance policy effective on or before the first tenant’s move-in date.
Apply for your local rental permit and schedule any required inspection.
Notify your county assessor’s office that the property is no longer your primary residence.
Register for any local or state tax IDs your jurisdiction requires for rental income.
Write down the exact date you moved out and keep it with your tax records. That date starts the five-year Section 121 clock.⁵
