Hey guys so here's the situation About 2 years back I sold a home security system to this older couple Well the other week I swing by their house to find out the Husband has past away I put out there that if they wanted to sell the house call me I'm interested and I could help them out I just got off the phone with daughter she called me asking if I was still interested I said yes I would be but I asked how much is left on the mortgage She told me about 80k And that there was a reverse mortgage on the home She said she'll call me back to confirm the price and when they are ready to move forward (within the month) I looked on Zillow and the estimated worth was 200k How can I make this work? Can I make this happen even with a reverse mortgage ? Cause there's a lot of potential profit here Thanks guys
