Houston multifamily investors should evaluate income, expenses, occupancy, financing, location, and capital needs before relying on
A good real estate decision starts with understanding the numbers behind the property, not just the headline price or advertised return. The sections below provide a practical way to review the issue before making a commitment.
Current Houston Multifamily Conditions to Underwrite
Houston's apartment market is working through a significant wave of new supply. The latest Cushman & Wakefield report recorded 3,772 unit deliveries during the quarter and stabilized vacancy of 11.1%. Vacancy improved by 30 basis points from the prior quarter but remained 70 basis points higher than a year earlier, suggesting that supply and demand are beginning to rebalance without eliminating lease-up risk.
Population growth still supports long-term housing demand, but investors should not assume that every recent growth rate will continue. Greater Houston Partnership reported that the metro added 126,720 residents in the latest annual period, the largest gain among major U.S. metros, while also noting that growth was about one-third below the prior record year and that both domestic and international migration had moderated. Underwriting should therefore use current submarket rents, concessions, occupancy, and absorption instead of applying one metro-wide growth assumption to every property.

Start With the Rent Roll
The rent roll shows the units, current rents, lease dates, deposits, and occupancy that support the property's income. Compare it with leases and bank or management records rather than assuming every scheduled rent is being collected. Look for below-market rents, month-to-month tenants, concessions, and concentrations of upcoming lease expirations.
Normalize Operating Expenses
Historical expenses need context. Taxes, insurance, utilities, management, repairs, payroll, and recurring maintenance should be adjusted to realistic forward-looking amounts. A property can look attractive if the seller's expenses are unusually low, but a buyer will own the future expense structure, not the seller's past one.
Inspect Deferred Maintenance and Capital Needs
Roofing, HVAC, plumbing, parking, exterior work, unit interiors, and major systems can materially change the economics of a deal. Separate routine operating expenses from capital needs and build a realistic reserve for work that may be required after closing.
Test the Financing
Run the deal under the actual loan terms being considered. Interest rate, amortization, required reserves, and debt-service coverage can change cash flow even when the property's operating performance stays the same. Stress-testing vacancy and expenses is especially useful before relying on a projected return.

The Bottom Line
The best multifamily underwriting combines the rent roll, actual expenses, physical condition, financing, and market context. A strong headline return is only useful when the assumptions underneath it can be supported.
