Fannie and Barney wanted more sales and financing, so they wanted to roll closing costs into the purchase price. So say a house is listed for $400,000 and closing costs are $12,000 (3%), then a purchaser could pay $400,000 cash, or $412,000 with the seller paying for $12,000 of the buyers closing costs. From the seller's standpoint, their net would be the same. Fannie would say the $412,000 is MV, because as a stakeholder, they changed the definition of MV so more 'average' people could buy houses. The definition of MV is 'suppose' to be cash or cash equivalent. It really isn't.
