What is the purchase price you are looking at?
Generally, these lenders will want a 30% down payment.
The rates are higher than what you see advertised on internet websites, as these are not traditional lender programs.
The programs that I have seen are 5/1 ARMS and 7/1 ARMS in the high 4s to low 5s interest rates.
The minimum loan amount this particular lender allows is $300k.
