I bought a SFH in Canton Ohio last year with the goal of making it a MTR due to the location (STR is NOT an option due to regulations but it is close to various hospitals) and the 4-car garage (makes for a lot of options).Long story short is I quickly acquired 2 other properties right after and spent all my focus setting these 2 properties up for doing the STR loophole for tax purposes (which was a complete success!).
