I want to buy something just to rent it out. Im in Boston and the prices ar through the roof but so is the rental market.
Would I be better off buying a condo and renting it out? a townhouse? or a home?
The multis in my area start at $600k and thats out of my range.

What do you look for when you want to buy a house and rent it out?
I read 2 books, one said to only buy homes with 3 bedrooms and 2 baths and another book ssaid to go for condos.
