Seller wants to stay after the sale

[Dan Marriggi]

Seller wants to sell her mortgage free home to me.

Haven't decided on a price yet. She wants to stay living in the home until her death. She is 80 years young.

She will cover all utilities but doesn't want to pay much rent ($200) or so.

I will be responsible for all typical homeowner expenses plus repairs and maintenance of the property.

Even if I buy at a discount price, I'd be subsidizing this "renter" for the rest of her life.

Any thoughts on structuring a win win offer ?
