Whether it’s a massive apartment complex in a downtown hotspot or a simple duplex in the suburbs, a multifamily property requires careful consideration—not to mention serious financial preparation—before diving in.

Average Costs of a Multifamily Home

Like any real estate, the cost of a multifamily home depends on a number of factors, including location, condition, the age of the property, and more. Generally, a multifamily unit (one rentable section of the property) is on par with other nearby single-family homes, at least from a price-per-square-foot standpoint. Upfront, you’ll need to budget for expenses like the:

On a regular basis, you’ll need to cover things like:

Property insuranceOngoing repairs and maintenanceManagement of the property (if you choose to outsource it)On-site securityLandscaping and common area upkeep

You’ll want to estimate these costs as accurately as possible before deciding to purchase a multifamily home (and before setting your rents); however, keep in mind that they can and will change over time. Insurance premiums fluctuate, and repairs may be minimal one year and extremely costly the next. Be sure you have a healthy financial cushion to cover these unexpected costs, just in case.

Multifamily Red Flags

Choosing the right property is the first step toward ensuring a successful multifamily investment—and that’s harder than it seems. Multifamily properties are at a premium, and you may have to sacrifice on location or condition of the property if your budget is particularly tight. Here are some red flags to steer clear of when looking for your investment property.

Slim Margins

Look at the full financial picture: the costs of the property, the expenses to operate and maintain it, and all of the other costs that come with it. Compare that to your potential income. Keep in mind that you might not be at full capacity immediately—or ever. If margins between costs and profits are small, it might not be the best fit. One unexpected repair or high-vacancy month could send you into the red. Make sure to calculate your potential cash flow and ensure there’s a healthy cushion in case of an emergency.

Bad Repair Jobs

Always have a qualified building inspector check out the property before you make a move. If there are deficiencies, get a contractor to estimate the costs to repair them. If repairs have already been made, ask the inspector to look at the quality of those repairs. If the work was poorly done, it could indicate more problems to come.

Unusually High Existing Rents

Just because a property has high rents now, that doesn’t mean it will always command those. Remember that the housing market is cyclical, and make sure you’ll still have healthy margins if those rents come down in a recession.

Best Practices

Having the right team can help you steer clear of some of these red flags and hone in on the best property for your investment goals. This should include a local real estate agent with experience in multifamily homes, an investor-friendly mortgage lender, and—in most cases—a real estate attorney. You’ll also want to:

Consider Hiring a Property Manager: A property manager can help take the day-to-day hassle and headache out of your multifamily investment. They’ll collect the rent, manage any repairs, and communicate with tenants on your behalf. Property managers can be particularly helpful if you’ve invested in an area you’re unfamiliar with, as they often come with distinct local knowledge and expertise.Get to Know Your Property’s History: Request copies of all existing leases, expense and income statements, utility bills, rent payments, service contracts, and more. Make sure it all aligns with your expectations of the property, and investigate any inaccuracies or suspicious activity. You should also talk to longtime tenants for honest feedback on the property and its previous management.Have a Financial Cushion: Ample cash reserves are vital in multifamily investing, especially if you have a large property with dozens of tenants. Assume you will always have some vacancies and that some tenants will fail to pay their rent consistently or on time. Make sure you still have plenty of funds to cover the mortgage, maintenance, insurance, and other costs of the property should something go awry.

The Bottom Line

Multifamily properties are harder to come by than single-family ones, so finding one that meets your needs and is in your price range might take some time. Be thorough in your search, check reputable investment property websites, and carefully vet each property you consider. Due diligence is crucial if you want to ensure that you’re making a profitable and successful investment.
