I have a single family house (primary residence) and am wondering the pros and cons of selling to a builder?

Quote from @Horacio Renteria: I became an accidental land lord after a divorce in 2020 (bought ex out for equity) then purchased a second home as primary in 2020 for 2.85% interest and has increased in equity 115%.
