Is it a scam?

[hollyking]

I found a couple of homes that are looking for people to take over their mortgages. I can afford the mortgage payment and they say they don't need any money down. My question is taking over someone elses mortgage real? It sounds too good to be true and that makes me question what's going on.

Do any of you have any information or resources I can look into to avoid a scam or bad deal?

ETA: Thanks for the great answers! This turned out to be a scam. When I called the number to ask questions the person on the phone was only interested in getting my credit card number to sign up for their website at $49.95/month. No thank you. I'll keep looking.
