How you do it, with some statistical certainty, is to reverse engineer the algorithm.

- rock, concrete, asphalt, Security $10,000, Electric/lighting $8,000; Other $10,000;  This is in the countryside so no engineering cost.Below is a layout.

Credit union possible if they have mortgage program for their own portfolio.You can do some reverse engineering by checking the mortgage of your neighbour and find out who is the lender , I know few direct lender.My condo is non warrantable too, usually you get quote from a broker and they will find the one that fits into your situation , if you can get 7 percent rate that’s a blessing lol
