Just as further clarification of my original answer, I believe this should be treated as a multiple phase project. The first phase being the purchase of the existing building and the second phase being the improvements to the building which based on the appraisal will result in a much higher value than the cost involved. If the loan was only to purchase the existing building and there were no or minimal improvements made then I would agree that you would have to base your LTV on the cost ($2.5 million). The reason is because there would be no apparent justification for using a higher value than purchase price if there were no improvements being made to support using a higher value. The way I read the guidelines the loan you contemplate would be treated the same as a construction loan for LTV purposes and assuming that it is a commercial real estate type property the appropriate LTV would be 80% of the appraised value ($3,200,000 x 80% = $2,560,000) but with funding not to exceed 100% of the cost of $2,500,000 ($2,000,000 purchase price of the building plus $500,000 for improvements).
