Quincy’s Zillow ZHVI typical city home value is $690,382, while Zillow ZORI typical observed city market rent is $2,750 per month. That pairing implies a 4.8% gross yield before every operating cost, so it is a screening ratio rather than a cap rate. Home value increased 0.9% year over year and rent increased 2.4%. The home value is 7.0x ACS median household income, and annualized ZORI equals 33.4% of that income, indicating affordability exposure without predicting any household’s capacity.
The city has 48,072 housing units. Renters occupy 54.8% of occupied homes, while the citywide vacancy rate is 5.8%; neither statistic proves a subject rental will lease quickly. Single-family homes are 37.7% of stock and large multifamily structures are 30.9%, showing mixed physical forms rather than purchasable inventory. ACS reports a $618,500 median value for surveyed owner-occupied housing and $2,118 median gross rent, including selected utilities. Those measures differ in concept and period from Zillow’s typical value and observed market rent and must remain separate.
Citywide, 48.7% of renter households meet the supplied ACS rent-burden threshold. Among vacant units, 959 are classified for rent, representing 34.4% of all vacancies; this survey reason is not live availability. Population changed 8.4% between overlapping ACS vintages; the change is not annualized, may reflect boundary changes and is not an event count. Median household income is $98,882, while poverty is 10.6% and unemployment is 6.9%. These are descriptive demand constraints, not causes or property-level tenant evidence.
At the county scope, Norfolk County’s Realtor median time on market is 37 days, useful for sale-market pacing but not a Quincy lease-up measure. At the metro scope, Boston employment declined 0.8% over the reported annual interval, a broad demand caution that cannot be assigned to the city. The Boston metro recorded 12,696 building permits in the reported period; metro permitting is a pipeline indicator, not Quincy supply. At the national scope, Freddie Mac’s 30-year mortgage rate is 6.58%, making debt assumptions sensitive to borrower and quote specifics.
Underwriting should therefore start from the subject property, not city averages or wider benchmarks. Verify the purchase price, achievable rent, lease and concession evidence, tenant-paid utilities, legal use, current occupancy, property taxes, insurance and flood terms, association charges, management, maintenance and capital needs. Inspect condition and systems, then obtain live financing and sale and rent comparables matched to the property type. Rebuild net operating income and cash flow under explicit vacancy, expense and financing assumptions; none of the supplied series provides property-level expenses, condition or insurability.
