I agree with Tim. It all depends on the original purchase situation. Buyer A goes into Dealer A, decides to buy a brand new 2002 Clayton Dream, 28 x 60. Buyer A has some money, arranged his own financing before shopping, used their own money to buy the land, prepare the site for installation, drills a well, has a septic tank installed, etc, etc. He pays $50,000 for the unit. Paid $20,000 for the land and paid out another $10,000 for the well, septic, site clearance, installation, foundation system. So Buyer A spends a total of $80,000. Next Buyer B walks into Dealer A, doesn't have any or very little money, has not done any preparation by talking to lenders or looking for a lot or anything else. But Dealer A is now his best friend who can get them the lot (exact same size) next door to Buyer A, has some good friends that drill wells, install septic systems, some more good friends to prepare the site and do the installation. Dealer A sends all his business to Mortgage Company ABC who orders all their appraisals from Appraiser C. Oh, oh Buyer B owes a lot of money on credit cards--needs to get those paid off, and doesn't have a down payment. So the dealer gives Buyer B a smoking deal of the same model of home, same size, same finish and amenities for $70,000. And because he is such good friends with the well driller, septim system installer, contractor that prepare the lot and install the home, all those things will only cost $40,000. Buyer B has obligated themselfs to a $100,000 mortgage. Two years later Buyer A sells his total package on the open market after exposure of a few months for $80,000. Buyer B decides to sell at the same time, but he lists the property for the $110,000 he put into it (on paper). After one year of marketing it hasn't sold, tries to refinance, can't because an appraisal only indicates a value of $70,000 to $80,000, not enough to pay off the mortgage. Eventually Buyer B goes into foreclosure, so walks away from the house angry and destorys the place. Foreclosure company finally is able to dump the property for $50,000. Both properties were duplicates originally--so what was the depreciation in the market if both homes had been equally maintained and with similar marketing techniques?? If you look at Buyer B, you might be tempted to say over 50%, but when you look at Buyer A, the depreciation would have been minimal. The big problem nationwide is all those Buyer Bs--and manufactured homes are in trouble. No wonder Fannie Mae's new guidelines preach against "created sales". And they have a division now that has the responsiblity to locate those situations.
