Sumter is the clearer first screen for cash flow and entry affordability, not a universal choice. Its Zillow city home-value index is $216,974.57081230122, below Salisbury’s $285,761.1027196618, and its stated gross yield is 8.460119369558396% rather than 5.065843597516239%. That yield is annual Zillow rent divided by Zillow value before all costs; it excludes vacancy, management, repairs, taxes, insurance, utilities, financing and capital work. Underwrite an address-level operating statement before treating the gap as investable return.
Salisbury better fits renter-pressure screening: its ACS renter share is 48.19483016449477% and vacancy rate 10.193771183730894%, compared with 42.77097195448044% and 14.18432146859491% in Sumter. Sumter nevertheless carries the higher Zillow rent index, $1,529.6923076923076 against $1,206.3508771929826, and rent growth is 4.311106784020335% against 1.2020642324682829%. Those Zillow measures are not ACS survey rents, so do not average them or use ACS median rent/value as competing appraisals.
Demand and stock split the choice. Sumter’s population change is 8.173366834170848% across overlapping ACS vintages and is not annualized, versus 6.2205354760280995% in Salisbury, and Sumter has 70.14248359037302% single-family stock versus 64.99328515699943%. Salisbury offers lower unemployment, 5.843787429868247% compared with 6.567129359617403%. Favor Sumter for detached-house sourcing; favor Salisbury for an occupancy-led renter thesis. Next, verify block-level vacancy, property condition, rent-ready scope and lease demand rather than extrapolating city indexes.
