USDA loans should be ordered as 'FHA type' assignments in terms of inspections. Both originate with HUD.
Jo Ann .... you state that closing costs can be added to the 'purchase price.' So what price is recorded as the 'SALE PRICE?' And if CC's are added to the 'purchase price', wouldn't those be reflected in subsequent appraisals for other properties as a concession when that home is used as a Comp?
One problem with this situation is CC's are not always known by or revealed to the appraiser ... so if the recorded sales price includes CC's, the market value of that dwelling, and thus potentially other surrounding properties, is artificially increased.
