I am looking at a triplex that needs a lot of work, sheetrock flooring, appliances and cabinets throughout. It has been completely gutted down to the framing then completely rewired so that is start. Foundation, roof, windows, doors and siding are all in very good shape. It is listed just over the tax assessed value and I would like to make an offer for 30% lower than the asking price and I have all cash in hand for the purchase. Does this seem reasonable?
