Property prices in Southern CA were making things difficult to get into the REI market on a single-income so I did the big option of moving out of state - no regrets but I do miss 65 degrees being "cold" hahaI've stuck to the central Indianapolis market simply because it is landlord-friendly and offers opportunities for all kinds of REI models, i.e. buy & hold or fix & flip or BRRRR.
