"Live in one unit, rent the others." It's one of the oldest ways to get started in real estate, and it still works. A small multi-family property gives you a home and a rental under one roof, and every month the tenants help pay down the loan while you build equity.
Small multi-family properties also come with their own rules. Lenders count rent differently, appraisers use a different report, triplexes and fourplexes face an extra FHA test, and buying with tenants in place means you inherit their leases. Here's what I walk buyers through, based on what I see in Marietta Real Estate and across Cobb County.
One note before we start. I'm a real estate broker and a certified residential appraiser, not an attorney, lender, CPA, or insurance agent. The financing, tax, and landlord-tenant points below are general information. Confirm how they apply to a specific property with a lender who regularly does 2 to 4 unit loans, a real estate attorney, and a tax professional.
1. What House Hacking Means for a Marietta Buyer
House hacking means buying a property with two to four units, living in one as your primary residence, and renting the rest. The rent from the other units offsets part of your monthly payment, and you build equity in the whole building, not just the unit you live in.
Because you live there, the loan is treated as an owner-occupied home loan, not an investment loan. That's why house hacking comes up so often with first-time homebuyers. It can be a practical first step into ownership and into being a landlord at the same time.
Is House Hacking a Fit for Your Marietta Plans?
- On-site landlord: Are you comfortable living next door to your tenants and being the person they call?
- Time: Do you have room in your week for repairs, showings, and rent collection?
- Reserves: Can you cover a vacant unit or a broken water heater without stress?
- Timeline: Do you expect to stay at least a year, which most owner-occupied loans require?
2. House Hack or Cash Flow: Two Different Strategies
The same fourplex can be a house hack for one buyer and a pure rental for another. The difference is whether you live there, and it changes almost everything about the purchase.
A house hacker usually qualifies for owner-occupied financing with a smaller down payment, and accepts that the property may not cash flow much while they live in it. A cash flow buyer is one of the investors looking for rental properties, rents every unit, and needs the numbers to work from day one. Investment loans on 2 to 4 unit properties typically require a much larger down payment, often around 25 percent, and some investors use loans that qualify on the property's rent rather than personal income.
Questions That Decide Your Marietta Strategy
- Occupancy: Will you live in one unit, at least for the first year?
- Cash: How much do you have for the down payment, closing costs, and reserves?
- Goal: Is monthly cash flow the priority, or long-term equity?
- Management: Will you handle tenants yourself, or budget for a property manager?
3. Owner-Occupied Loans Can Mean a Smaller Down Payment
When you live in one unit, several loan programs open up. FHA loans allow as little as 3.5 percent down on owner-occupied properties of one to four units. Since November 2023, Fannie Mae conventional loans have allowed as little as 5 percent down on owner-occupied 2, 3, and 4 unit homes, down from 15 to 25 percent before. Eligible veterans and service members may be able to use a VA loan on a property of up to four units, as long as they live in one of them.
Each program comes with its own credit, reserve, and occupancy rules, and loan limits for 2 to 4 unit properties are higher than for single-family homes. As a HUD approved broker, I'm happy to help you understand how an FHA purchase works, but your lender sets the final terms.
Financing Steps for Marietta Multi-Family Buyers
- Choose the right lender: Ask up front whether they regularly close 2 to 4 unit owner-occupied loans.
- Ask about limits: Get the current loan limits for a 2, 3, or 4 unit property in Cobb County.
- Plan for reserves: Multi-unit loans often require several months of payments in the bank after closing.
- Compare side by side: Ask for FHA and conventional estimates on the same property.
4. The FHA Self-Sufficiency Test for Triplexes and Fourplexes
FHA adds one extra hurdle for 3 and 4 unit properties called the self-sufficiency test. The property has to show it can carry its own payment. In general, 75 percent of the appraiser's estimated market rent for every unit, including the one you'll live in, has to meet or exceed the full monthly payment of principal, interest, taxes, and insurance. Duplexes aren't subject to this test.
With a 3.5 percent down payment, many triplexes and fourplexes have a hard time passing, so run this math before you write an offer. If the numbers fall short, a conventional owner-occupied loan with 5 percent down doesn't use the self-sufficiency test and may be the cleaner option.
Run the Self-Sufficiency Math on a Marietta Triplex
- Step 1: Add up the market rent for every unit, including yours.
- Step 2: Multiply that total by 75 percent.
- Step 3: Compare it to the full monthly payment, including taxes, insurance, and mortgage insurance.
- Step 4: If it falls short, ask your lender about a conventional option before you give up on the property.
5. How Lenders Count Rental Income
The rent from the units you won't live in can help you qualify, but lenders don't count all of it. Most generally count around 75 percent of the gross rent, documented from current leases or the appraiser's market rent schedule. The other 25 percent is set aside for vacancy and expenses.
Rules vary by program and lender. Some ask for landlord experience or extra reserves before they'll count projected rent, and some will only use existing leases. Ask early, because this one detail can change how much you qualify for.
Rent Documents to Request on a Marietta Multi-Family
- Current leases: A signed copy for every occupied unit.
- Rent roll: Unit, rent, lease dates, and deposit for each tenant.
- Payment history: A ledger or deposit records showing rent actually collected.
- Expenses: Utility bills the owner pays, plus recent repair and maintenance costs.
6. How a 2 to 4 Unit Property Gets Appraised
Small multi-family properties are appraised on a different report than single-family homes. Lenders typically use Fannie Mae Form 1025, the Small Residential Income Property Appraisal Report. Along with comparable sales, it includes a market rent analysis for each unit and often an income approach that relates the property's rent to its value.
Comparable sales of duplexes, triplexes, and fourplexes are thinner than single-family sales, so appraisers sometimes have to look farther afield or further back in time. That's where an offer can get ahead of the appraisal if you're not careful.
How a Certified Appraiser Looks at Marietta Multi-Family
I look at small income properties the way a lender's appraiser will: closed sales of similar buildings, the rent each unit can realistically bring, unit mix, condition, and how many legal units the property really has. When Marietta sales are limited, I compare small income properties in nearby areas, including Kennesaw Real Estate, Acworth Real Estate, and Smyrna Real Estate. That helps buyers avoid overpaying and helps sellers price for buyers who can actually get the loan.
7. Confirm the Legal Unit Count and Zoning in Marietta
Some properties marketed as duplexes are single-family homes that were divided without permits. Lenders, appraisers, and insurers generally rely on the legal unit count, so an unpermitted unit may not count toward value, rental income, or coverage.
Location matters here too. A Marietta mailing address can be inside the City of Marietta or in unincorporated Cobb County. Each has its own zoning rules, permit records, and tax bills, so confirm which one applies before you count on rent from every unit.
Zoning and Permit Questions for a Marietta Multi-Family
- Jurisdiction: City of Marietta or unincorporated Cobb County?
- Zoning: Does the district allow the number of units the property has?
- Permits: Are there permit records for any conversion, addition, or second kitchen?
- Utilities: Are units separately metered, or does the owner pay for some or all of them?
- Covenants: Any HOA or recorded restrictions on renting?
8. Running the Cash Flow Numbers the Right Way
Rent minus the mortgage is not cash flow. Start with gross rent and subtract a vacancy allowance, repairs, reserves for big-ticket items like roofs and HVAC systems in every unit, property management, property taxes, insurance, any utilities the owner pays, and lawn care and trash. What's left is net operating income, or NOI.
Two other numbers come up in every investor conversation. Cap rate is NOI divided by the purchase price, and it's useful for comparing buildings. Cash-on-cash return is your annual cash flow after the mortgage, divided by the cash you put in, and it shows what your money is actually earning.
Cash Flow Checklist for a Marietta Rental
- Use real rents: Base the math on current leases and realistic market rent, not the highest number you've heard.
- Budget for vacancy: Assume each unit will sit empty for some time between tenants.
- Count every system: Two to four units means two to four water heaters, HVAC systems, and kitchens to maintain.
- Get real quotes: Insurance and taxes on a multi-unit property can differ from a single-family home.
9. Buying With Tenants in Place
When you buy a property with tenants, their leases generally stay in effect and transfer to you, along with their security deposits. You inherit the rent, the lease end dates, and any promises the current owner made. That's why lease review belongs in your due diligence period, not after closing.
Georgia's Safe at Home Act changed the rules for leases entered into or renewed on or after July 1, 2024. Landlords must keep rental homes fit for human habitation, security deposits can't exceed two months' rent, and tenants get notice and a short window to pay before an eviction can be filed. If you're weighing tenant-occupied properties, build these rules into your plan from the start.
Tenant-Occupied Checklist for Marietta Buyers
- Lease review: Rent, end dates, renewal terms, pets, and who pays which utilities.
- Tenant estoppel: Ask for signed statements confirming rent, deposit, and lease terms.
- Deposits: Confirm with your closing attorney how deposits will be transferred at closing.
- Showings and inspections: Give tenants the notice their lease requires.
- Fair housing: Use the same written screening criteria for every future applicant.
10. Plan the Long Game: Live In, Move Out, or Exchange
The best multi-family purchases have an exit plan on day one. Some owners stay for years and let the rents carry more of the payment over time. Others meet their loan's occupancy requirement, move into a new home, and keep the building as a full rental. Some sell, and some refinance.
Owners who later hold the property purely as a rental sometimes use a 1031 exchange to trade into a larger building. The part you live in and the parts you rent can be treated differently for tax purposes, so talk with a CPA before you buy and again before you sell.
Exit Questions to Ask Before You Buy in Marietta
- Moving out: Would the property still work if you rented your unit too?
- Big systems: When will the roof, HVAC systems, and water heaters need replacing?
- Future buyers: Would it appeal to both owner-occupants and investors when you sell?
- Records: Will you keep clean leases, rent rolls, and expense records from day one?
