<p>Gee, eff, is this a house you'd like to buy?</p>
<p>You could rent with an option to buy. Same rent, but say $400 a month of the rent going for a downpayment as long as you live there. You could have a provision that at the time you excercise the option, the purchase price will be no more than $__________, but the price shall be determined by the percentage drop of the median income in the _____zip code (or county, or whatever), such that the purchase price shall decrease by the same percentage amount as the median drop. and then, to appease the landlord, add something to the effect that if he finds a bagholder, err, buyer willing to buy for more than your max, you will quietly slink away. Not gonna happen, but saving face is really important.</p>
