Experience buying a foreclosure from a reverse mortgage compa

[Grant Carrington]

Wondering if anyone has any experience purchasing a foreclosure from a reverse mortgage company.  I'm in the process of negotiating a price and terms on my first sfh investment property.  My realtor is telling me the seller will not do any closing costs, even if offer is above asking price, will not turn on utilities for an inspection and requires that our offer indicates atleast 20% down towards our mortgage before they will even entertain my offer.  Any advice would be greatly appreciated especially since I found a lender that will do 15% down.
