Koreatown is one of LA's highest density rental submarkets and among the most actively traded for small multifamily because the building stock, 1920s to 1950s courtyard apartments, is everywhere and transactions are frequent. Lee + Associates put average price per unit at $170,000 and the average cap rate at 6.1 percent for the Koreatown submarket in their Mid Year 2025 report. That makes it one of the most affordable entry points on this list.
The LA City RSO covers the overwhelming majority of the inventory (pre 1978 buildings), with the same 3 percent allowable increase for July 2025 through June 2026. Matthews' Q4 2025 LA report noted Koreatown experienced approximately negative 1 percent rent growth due to new supply absorption, with vacancy around 6 percent. Development in LA is concentrated in Koreatown, Downtown, and Hollywood, so the supply pressure is real.
The value add thesis here is below market RSO rents, which are common in buildings where tenants have been in place for years. Turnover units reset to market, which in Koreatown runs $1,900 to $2,800 per month for one bedroom units. Investors should model conservatively on the turnover assumption: RSO buildings in Koreatown have some of the most stable long term tenancies in the region.
Measure ULA applies to City of Los Angeles transactions above the 5.4M threshold. For small assets priced under 5.4M, ULA is not triggered, which covers most 2 to 10 unit Koreatown sales.
For investors targeting the lowest entry basis on our list, with a long horizon, willing to operate inside a 3 percent RSO ceiling and patient for turnover, Koreatown is the cap rate champion.
