For Alexandria, the decision frame starts with Zillow's typical city home value of $679,077 and typical observed market rent of $2,318 a month. Their direct relationship is a 4.1% gross yield, calculated before vacancy, management, maintenance, insurance, taxes, financing and capital work. The Zillow value is 5.67x ACS median household income, while annual Zillow rent is 23.2% of that income; these are broad affordability references, not a property's cash flow or a household qualification test.
Citywide stock contains 80,844 units; 57.9% of occupied units are renter-occupied, and 5.9% of all units are vacant. The median year built is 1974, making age-related condition variation a property-level question. ACS reports a $735,100 median home value for surveyed occupied owner housing and $2,089 median gross rent for surveyed renter housing, with gross rent including contract rent plus selected utilities. Those ACS medians differ in definition and period from Zillow's typical value and observed market rent and should not be averaged or substituted.
Direct city context shows 45.3% of renter households meet the ACS rent-burden threshold. Single-family units comprise 34.7% of stock and large multifamily units 41.8%. For-rent vacancies are 39.9% of vacant units; that vacancy-reason share does not measure live listings or leasing speed. Population is 156,976, down 0.4% between overlapping ACS vintages; the change is not annualized, and possible boundary changes are not isolated. Median household income is $119,681, unemployment is 3.3% and poverty is 7.9%. These are descriptive demand constraints, not causal evidence about a specific asset.
At county scope, Alexandria City's FHFA index shows 23.2% growth over its supplied multi-year window; this repeat-sales trend is not the city Zillow value. At county scope, Alexandria City's effective property-tax rate is 0.956%; parcel bills can differ. At county scope, Alexandria City's FEMA climate-loss ratio is 0.124%, a screening metric rather than parcel hazard, insurability or premium. At national scope, the Freddie Mac 30-year mortgage rate is 6.58%, financing context rather than a borrower quote.
Underwriting should treat all benchmarks as screening inputs. Verify asking price, achievable unit-specific rent, lease and occupancy status, concessions, utilities, association rules and dues, parcel tax bill, insurance quote, hazard exposure, inspection findings, deferred maintenance, reserves, closing and management costs, financing, and legal compliance. Rebuild net operating income and debt coverage from those records, then test downtime and repairs; citywide tenure, vacancy, burden and structure statistics cannot establish demand, condition or returns for a property.
