Talked to a guy about renting an existing home to buy something else, and they're only counting rental income if you have 30% equity (almost no one these days) or have 2 years of rental history. Sales will slow further as the only people buying are first-time buyers, and it's essentially impossible for anyone to move up - can't sell, can't use rental income for buying something else, can't say "fuck it" to the old, far underwater house and still get a loan to buy a new place. Gonna be a looooonnng, slow recovery.
