Rent-controlled buildings offer stable, long-term tenancies but limit annual rent increases and can keep rents well below market for years. Non-rent-controlled buildings (generally those built after 1979) allow more flexibility, faster rent adjustments, and different turnover patterns. The right choice depends on your investment goals. Investors prioritizing stability and low management intensity often prefer rent-controlled properties in strong neighborhoods. Those seeking more active return growth lean toward newer product. I help investors evaluate both with clear financial projections.
