Property for sale with a second mortgage taken out

[TamaraFaye Smith]

So I am a real estate investor just starting out. I have a potential property, the seller is motivated and verified there aren’t any back taxes, and the home is owned by him, no banks involved. But he lets me know there is a 2nd mortgage taken out on the home. My question is when I find the buyer to purchase am I asking for the sellers original asking price plus the 2nd mortgage or just one or the other?
