9. If you're buying a condo, know the rules
Condo lending rules have become more stringent, making it difficult for some would-be buyers to get financing. Lenders generally want buildings to be at least 50 percent owner-occupied, Dwyer says.
They don't one want one person to own more than 10 percent of the units, he adds, since that owner could sway how money is spent and, hypothetically, decide against making repairs. (Which, of course, may not bode well for actually living there.)
Buyers may also have trouble getting financing for condos in buildings with a certain amount of commercial space.
