I agree with @Chad U. on the deal points and condition of the property. I bought a half dozen HECMs a few years ago and resold them as REO after foreclosure or quitclaim deed. One of the caveats is that many times the interiors still have a HUGE amount of trash from the deceased borrower, especially if not heirs are around to clean up , so factor in a generous trashout budget. These loans should include an aged inspection report for the interior with winterization and those juicy photos of trash in every room. Also look for heirs to see if they are willing to QCD the property to you to mitigate foreclosur expenses, especially if you are looking to take the property and sell REO. 3 out of the six loans I purchased had the kids deed the property over.
Also, check with your servicer to see if they will board the loan. FCI does not, but Madison and a few others will. Since there are no future payments to manage, you could technically self service, but I always like to have a servicer on my side.
