Lynn’s Zillow ZHVI typical city home value is $595,053, versus Zillow ZORI typical observed market rent of $2,300 monthly. Annualized ZORI divided by ZHVI gives a 4.6% gross yield before operating costs, capital work and financing. ZHVI is 7.9x ACS median household income, while annual ZORI equals 36.8% of that income; these are affordability flags, not borrower payment tests. Annual Zillow home-value growth was 0.5% and rent growth 2.2%, city indicators rather than forecasts or net returns.
The city has 37,960 housing units, a 4.1% vacancy rate and a 51.9% renter share among occupied units. ACS puts median year built at 1946, a citywide cue to inspect systems, not evidence about an address. ACS median home value is $510,100; median gross rent is $1,722 and includes selected utilities. These occupied-housing survey measures differ in concept and period from Zillow’s typical value and observed market rent, so they must not be averaged or treated as comparable quotes.
ACS reports 60.0% of renter households are rent-burdened. Single-family homes represent 39.1% of units and large multifamily properties 16.9%. Of vacant units, 33.2% are classified for rent, but vacancy reasons and structure shares do not measure available inventory or leasing speed. Population is 8.5% higher between overlapping ACS vintages; this is not annualized and may reflect boundary changes. Median household income is $75,043, while poverty is 13.8% and unemployment 5.0%. These constraints are descriptive, not causes of rent performance or proof of tenant quality.
At the county scope, Essex County listings have a median 32 days on market and a 14.9% price-reduced share, sale context that does not measure city pricing or property liquidity. In the Boston metro, payroll jobs fell 0.8%, a demand caution that neither identifies Lynn employment nor establishes housing causation. At the national scope, the Freddie Mac mortgage rate is 6.58%, a benchmark rather than a borrower quote. County, metro and national measures use separate geographies and denominators and cannot form a city estimate.
Underwriting is limited by citywide averages, mixed periods and missing address-level operations. Gross yield excludes operating and capital costs; ACS tenure and vacancy cannot establish lease-up; wider context cannot resolve property condition. Verify unit rent, concessions, leases, utilities, taxes, insurance and address-level hazards, management and turnover costs, code and permit status, major systems, deferred repairs and association obligations. Recalculate cash flow from actual price, financing and reserves, then stress vacancy, repairs and exit costs without assuming city averages will hold.
