Want to know how old the roof is on a house, or whether it uses gas or electrical heat? Your trusty real estate agent can tell you pretty much anything you need to know about a home you’re hoping to buy (or at least find answers for you). Yet if you ask your agent certain questions, you might be puzzled to hear nothing but an awkward silence. Why? It’s not that real estate agents don’t know the answer; they probably do. It’s just that they’re correctly staying on the right side of the Fair Housing Act, which prohibits housing discrimination based on race, religion, sex, or family/economic status. So that silence is actually a good thing—it means that your agent is conscientiously steering clear of the tinderbox issues hidden within your innocent questions. Here are the top ones that leave them feeling tongue-tied—plus where you can actually find the answers you seek.
