Philadelphia County presents a cash-flow-versus-exit tension: Zillow’s 2026-06 county median home value is $237,474, up 0.36% year over year; median asking rent is $1,814 a month, and supplied gross yield based on annual market rent before costs is 9.17%. The county merits investigation for operators able to validate neighborhood rents and flood exposure; it warrants caution for buyers dependent on a fast resale or county-level averages. This is measured asking rent, distinct from HUD’s payment standard.
HUD’s two-bedroom Fair Market Rent is a payment standard, not an estimate of asking rent, and must not be substituted into yield. The 0.82% effective property-tax rate is a carrying-cost input, but insurance, debt, repairs, vacancy, and utilities are not published; net yield therefore cannot be underwritten from this record. FHFA’s 2025 repeat-transaction HPI increased 3.80% annually and 28.21% cumulatively over five years. It supports the same positive direction as Zillow’s value change, but cannot be averaged with Zillow because the vintages and methods differ.
Listing-market and household evidence add friction. Realtor.com’s 2026-06 MLS record shows 4,810 active listings and a 9.20% year-over-year decline in median listing price; listings are visible supply and asking prices, not closed-sale evidence. QCEW’s 2025 annual covered workplace employment grew 1.53%; it is neither resident employment nor unemployment, while Education and health services is only the largest disclosed private supersector. Tax-return migration was net negative 5,208 households, with inbound mover AGI $16,824 below outbound mover AGI. Investor mortgages represented 17.23% of 12,961 purchases: meaningful competition, but not a measure of cash acquisitions or all investor purchases.
Inland flood is the dominant hazard, and modeled expected climate loss equals 0.12% of building value per year; this county-level ratio is not a property insurance quote. The combination shifts diligence toward parcel flood history, elevation, coverage terms, and premiums. Missing submarket rent comps, lease-renewal and vacancy data prevent a durability judgment; closed-sale comps, financing terms, and property-level condition prevent a defensible exit-price and net-cash-flow conclusion. County evidence does not establish performance for a particular block or asset.
