Portland’s Zillow ZHVI typical home value is $571,364, while Zillow ZORI typical observed market rent is $2,429 monthly. Together they imply a 5.1% gross yield before every operating cost. Zillow ZHVI fell 0.9% year over year while ZORI rose 3.0%. On the supplied cross-source screens, ZHVI is 7.18x ACS median household income and annualized ZORI is 36.6% of that income, indicating affordability pressure. Gross yield excludes taxes, insurance, maintenance, management, vacancy, utilities and financing.
Citywide, 53.1% of occupied units are renter-occupied, while 9.8% of all housing units are vacant. These citywide shares describe tenure and housing-stock status, not the leasing odds for one property. ACS reports a $1,577 median gross rent, including contract rent plus selected utilities, and a $489,600 owner-reported median home value for surveyed occupied housing. These ACS measures differ in definition and period from Zillow’s typical-market measures and must not be averaged.
Direct city context shows a 51.3% rent-burden share. Units in single-family and large multifamily structures represent 40.6% and 15.6% of housing units. Among vacant units, 18.4% were for rent and 1,888 were seasonal. Population was 3.4% higher across overlapping ACS five-year vintages; median household income is $79,540, poverty is 11.2%, and unemployment is 4.2%. These survey facts may reflect boundary changes and cannot establish annual population growth, available investment inventory, property-level leasing speed or causal demand effects.
Cumberland County context reports a 32-day median time on market and price reductions on 17.5% of active listings; this frames county resale conditions, not Portland liquidity. The Portland, ME metro has 2.7 months of supply and 0.34% year-over-year job growth, pairing limited metro inventory with modest metro employment expansion without measuring the city. The national Freddie Mac 30-year mortgage rate is 6.66%, a national financing benchmark rather than a borrower or property quote.
Underwriting should not treat citywide vacancy as expected downtime or structure shares as purchasable inventory. Next verify the address-specific asking price and achievable rent; lease terms and utility responsibility; taxes, insurance and hazard costs; condition, deferred maintenance and capital needs; legal use and unit status; tenant history; management costs; and financing quotes. Stress-test vacancy, repairs and exit liquidity, then reconcile Zillow screening metrics with comparable leases, sales and an inspection before deciding.
