I’m not in the biz but I contacted a lender about the same thing a few weeks ago, of course HLS can give the true skinny. What I found out was 25% down and you had to qualify without factoring the rent as income, meaning you ahd to qual and prove income to cover all properties as if none received any rent. This may be why they are priced well, only those with cash reserves and serious cushion can buy. They are doing this to defend against bait and switch people, those that want to buy at lower prices and downsize, then walk away from their primary, pretending to be planning on renting the newly aquired property, but moving in it instead and jingle mailing the first.
