Garage converted into living space, convert it back?

[Jay Y.]

Hi all, I have a house I'm interested in purchasing. It's a 1 story; 3bed/2bath home about 1500 sq ft. The garage has been converted into a family room and siding covers what was the garage door. I still can't decide whether I want to flip it or if I should rent it out. For resale, my opinion is the lack of a garage is a detriment but having extra living space for a rental could be an attribute - although I could be completely wrong.

Please share your opinions! Thanks!!
