I grant the foreclosure rate is higher on mfg homes than site built homes. To a certain extent, this is a function of the cost of a mfg home is almost always lower than a stick built home that equates one to one in terms of what is there. So, the buyer who does not make as much is the one who buys the mfg home. Because he skates a lot closer to the edge than the more affluent members of society, he is more likely to fall into foreclosure than the buyer of a stick built home.
In the end, as a RE salesperson, I wish the lending community would concentrate on the buyer's ability to pay more than the type of house it is. In the end, that is what matters.
As to which to purchase, obviously, due to lending, if you can buy a stick or modular (technical term which does not include MFG even though they are functionally equivalent.) do so.
