Certain types of homes are predicted to lose value in the next 12 to 18 months due to high interest rates and housing prices. Condominiums and urban apartments may decline in demand due to oversupply and remote work trends. Older suburban homes are struggling against new constructions, while luxury properties face price reductions from economic fluctuations. Additionally, homes in areas with high unemployment rates and vacation or second homes are expected to see value drops as buyers become more cautious.
