Miami’s current Zillow measures set the initial price-rent frame: ZHVI typical home value is $582,621 and ZORI typical observed market rent is $3,004 monthly. Their implied gross yield is 6.2%, calculated as annual ZORI divided by ZHVI before management, maintenance, insurance, taxes, association charges, vacancy or financing. ZHVI is 9.3x ACS median household income, while annualized ZORI equals 57.7% of that income; both are affordability screens, not a property budget or tenant qualification.
The city has 223,826 housing units; 69.2% of occupied units are renter-occupied, and the citywide vacancy rate is 13.0%. Those citywide measures cannot show whether a specific rental will lease promptly. ACS reports a $518,100 median owner-reported home value and $1,758 median gross rent for surveyed occupied housing, with gross rent including selected utilities. These ACS measures differ in concept and period from Zillow’s typical value and observed market rent and should not be combined.
Direct city survey depth adds constraints and stock composition: 62.9% of renter households meet the reported rent-burden threshold, while single-family units are 31.3% and large multifamily units 48.8% of all housing units. Among vacant units, 9,450 were classified for rent and 9,480 as seasonal; these are ACS vacancy reasons, not available investment listings. Population was 1.2% higher between the overlapping ACS five-year vintages, not an annual rate, and possible boundary changes remain relevant. Median household income is $62,462, with poverty at 19.4% and unemployment at 5.2%; these describe demand constraints but do not establish causation or property performance.
Miami-Dade County recorded 17,024 active listings, a median 86 days on market and a 12.2% price-reduced share; these county measures do not describe Miami city inventory. The broader Miami metro recorded job change of -0.3%; that metro denominator does not establish city demand or city supply. The national Freddie Mac 30-year mortgage rate was 6.58%, a national financing benchmark rather than a borrower quote or city return measure.
The principal underwriting gap is the absence of property-level revenue, condition, expense and legal data. Next checks should verify achievable rent, lease terms, occupancy and concessions; inspect major systems and deferred maintenance; and obtain insurance, flood-zone, association, tax and utility details. A financing quote, title review, rental-rule review and unit-specific expense history are also needed. Recalculate net operating income, debt coverage and cash requirements from those documents rather than treating citywide vacancy, Zillow gross yield or wider-market statistics as asset-level evidence.
