Rental property is the entry point for most real estate investors, and for good reason: a single-family home or small multifamily building in Missouri is understandable in a way a syndicated office deal is not. That familiarity is also why so many first-time landlords underestimate what actually drives whether a rental performs, focusing on purchase price and rent comps while giving less attention to the ongoing costs that determine net return.
Underwriting a Rental Before Buying
A useful rental analysis starts with realistic vacancy, typically assuming several weeks of vacancy between tenants even in a strong market, and a maintenance reserve built from the property's age and condition rather than a flat percentage guess. Property management, if the owner is not self-managing, generally runs eight to twelve percent of collected rent. Skipping any of these in the initial math is the most common reason a rental's actual performance disappoints relative to the pitch that sold it.
Single-Family Versus Small Multifamily
A single-family rental concentrates all income risk in one tenant; when it is vacant, income drops to zero. A small multifamily building spreads that risk across several units, so one vacancy is a partial hit rather than a total one, though it also usually means more maintenance calls and more tenant turnover to manage across the building. Missouri investors choosing between the two are really choosing between simplicity and income stability.
Financing also differs between the two. A single-family rental can often use conventional residential financing, while a building of five units or more typically requires commercial underwriting based on the property's income rather than the borrower's personal financials alone.
When Self-Managing Stops Making Sense
Many owners self-manage their first rental to save the management fee and learn the business. That tends to work until either the owner acquires a second or third property, moves out of the area, or simply runs out of patience for after-hours maintenance calls. At that point, hiring a manager, or moving toward a passive structure entirely, often produces a better after-tax, after-time outcome even accounting for the fee, though that calculation is specific to each owner's situation.
Selling a Rental Without Losing Value to Tax
An owner who has held a Missouri rental for years and built up significant appreciation faces a real cost if they simply sell it outright: capital gains tax, plus depreciation recapture on whatever depreciation was claimed along the way, both due in the year of sale. A 1031 exchange defers both by rolling the proceeds into replacement property, whether that means trading up to a larger rental, moving into a different property type entirely, or exiting active management through a DST interest, provided the exchange stays within the 45-day identification and 180-day closing windows.
Common 1031 Exchange Questions
What vacancy rate should you assume when underwriting a rental?
Many investors use a few weeks per year even in a strong rental market, and a higher figure in markets with more seasonal or economic volatility. Using zero vacancy in a projection generally overstates likely returns.
Is a duplex or fourplex a better first investment than a single-family home?
It depends on the investor's tolerance for hands-on management. Multifamily spreads vacancy risk across units but usually involves more maintenance and tenant turnover than a single well-maintained single-family rental.
Do you have to reinvest in another rental to use a 1031 exchange?
No. The replacement property needs to be like-kind investment or business real property, which can include a different property type entirely, such as commercial space or a DST interest, not necessarily another rental home.
How does depreciation recapture affect the sale of a rental?
Depreciation claimed during ownership is generally taxed as recapture upon sale, separate from and in addition to capital gains tax on appreciation, and a 1031 exchange defers both when structured properly.
At what point should you hire a property manager instead of self-managing?
There is no fixed threshold, but owners who add a second property, move away from the rental, or find maintenance calls interfering with their primary work often find a manager's fee worth the trade despite reducing net income.
Does a multifamily property require different financing than a single-family rental?
Properties of five units or more generally require commercial financing underwritten on the property's own income and debt service coverage, unlike a single-family rental, which typically qualifies for conventional residential loan terms.
