Seller financing with a mortgage

[Jacob Rzewnicki]

Hey everyone,

I stumbled across a property that belongs to a family friend. My dad is helping her rehab it before the next tenants move in (she had a terrible experience with the last tenants). It’s a town home and I mentioned to my dad I might want to buy it off of her since she isn’t exactly and investor. His first instinct was that she might not want to sell since it’s her primary source of income.

Of course seller financing popped into my head, so she’s still getting paid without the hassle. I mentioned it but he noted that she might still have a mortgage on the place.

How do i go about negotiating a seller finance deal when there’s still a mortgage remaining on the property?

Thanks in advance!
