Starting a Rental Property Business, Step by Step

A rental business is a small business with one product: a home someone else lives in. Most first-year problems come from skipping a step, not from bad luck. Here are ten steps in the order they matter, with a single-family house worked through from offer to first rent.

1. Run the numbers before you shop

Decide what a property must earn, then price it. The yardstick is net operating income: rent minus a vacancy allowance and operating costs, before the mortgage.

A house is listed at $250,000 and would rent for $1,950 a month. Allow 5% vacancy and 8% management, even if you plan to manage it yourself, plus $240 a month of property tax, $120 of insurance and $160 of repairs.

The NOI calculator shows $14,211.60 a year. At the asking price that is a 5.7% cap rate.

If you want 6.5%, the cap rate calculator in reverse puts your ceiling at $218,646. That is your offer range, whatever the listing says. The cap rate guide explains the bands.

2. Line up the cash

Under the conventional loan guidelines most lenders follow, a one-unit investment property needs at least 15% down, and two to four units need 25%. Lenders also want reserves: six months of the new loan’s payment, including tax and insurance, in the bank after closing.

The seller takes $218,000. You put 25% down, $54,500, and borrow $163,500 at an example rate of 7% for 30 years: $1,087.77 a month. With tax and insurance, the payment is $1,447.77, so six months of reserves is $8,686.62.

NOI of $14,211.60 minus $13,053.24 of loan payments leaves $1,158.36 a year, or $2,936.76 if you manage it yourself and keep the fee.

Add closing costs and a make-ready budget for paint, locks and small repairs. Thin cash flow like this is normal in the first years; reserves are what keep a vacancy or a furnace from becoming a crisis.

3. Learn your state’s rules

Landlord-tenant law is state law, and it shapes your lease before you write it. The state guides cover each state’s statute. Three tables matter on day one: security deposit limits and return deadlines, landlord entry notice and notice to end a month-to-month tenancy. Cities can add their own rules on top.

4. Decide how to hold the property

Your own name, an LLC or a partnership each trades cost and paperwork for protection, and each changes how you borrow. The guide to how small landlords hold rentals walks through liability, taxes and the due-on-sale question. Decide before closing if you can; moving a mortgaged property into a company later is harder.

5. Get an EIN and a separate bank account

An employer identification number is free from the IRS and takes minutes online. The IRS warns against websites that charge for one. Open a bank account used only for the rental, so rent, deposits and repairs never touch your personal money. The guide to bank accounts for real estate investors lists what to look for, including where your state wants security deposits held.

6. Insure it as a rental

A homeowners policy is written for a home you live in. Tell the insurer the home is rented and buy a landlord policy with liability limits that match what you own. The guide to landlord insurance coverages covers each part.

7. Check local registration and inspections

Many cities and counties require rental registration, a business license or a safety inspection before a unit is rented. Call the city or county housing office, and ask about smoke and carbon monoxide alarm rules while you are on the phone.

8. Make the unit ready, and document it

If the home was built before 1978, federal law requires a lead-based paint disclosure. You give the tenant the EPA pamphlet “Protect Your Family From Lead in Your Home,” disclose any known lead paint and reports, put a lead warning statement in the lease, and keep the signed disclosure for three years.

Photograph every room before move-in and do a written move-in inspection with the tenant. It is your evidence when the deposit comes back.

9. Set the rent, screen fairly and sign

Price against the listings near you; the guide to how much to charge shows how. Write your screening criteria down and apply them to every applicant. The federal Fair Housing Act bars discrimination based on race, color, religion, sex, national origin, familial status and disability, and many states and cities add more.

Your rent is $1,950. At a 3× income screen, the rent-to-income calculator shows an applicant needs $5,850 a month.

A clear lease prevents most disputes; the lease agreements guide explains each clause.

10. Keep the books from the first day

Rental income and expenses go on Schedule E. The building, not the land, is depreciated over 27.5 years. Keep the closing statement, every receipt and a rent roll of who pays what and when; give a rent receipt for every payment. The 10 rental tax mistakes are worth reading before your first April.

Four first-year mistakes to skip

• No written screening criteria. Deciding case by case invites fair housing trouble and bad tenants alike.
• A deposit handled loosely. Deposit limits and return deadlines are set by state law, and missing a deadline can cost more than the deposit.
• Entering without notice. Many states set a notice period for entry, and the lease can add its own; learn yours before the first repair visit.
• Pricing the rent once and never again. Check the market every renewal, and give notice the way your state requires.

The guide to mistakes independent landlords make covers each one with the fix.

A sample timeline

• Friday, October 30, 2026: close; change the locks; start the make-ready.
• Friday, November 13: photos done, listing live, screening criteria posted.
• Tuesday, December 1: lease starts, move-in inspection signed, first rent deposited in the rental account.

Four weeks is tight but possible for a house in good shape. Whatever the dates, keep the order: numbers, cash, rules, then the tenant.
