Seller Financing - Got one on the hook!

[Matt Hudson]

Last week I received a call from a mailer. The gentleman asked me abruptly, "How much will you buy my house for?!". Before I could reply he proceeded to berate me and call me a "f*#$%ing vulture". 

Fast forward to today I get a call from a nice lady who rents her a house in East Nashville. One of the hottest markets in Nashville and just down the street from my home. She owns it outright and is willing to talk about a purchase. I WANT THIS HOUSE!

She has had the same renter for 15 years and the renter takes great care of the house. I drove by the home and it look like an older woman that has really put her roots down. 

East Nashville, like many other urban neighborhoods, has seen major gentrification. Affordable housing is an issue and older renters and homeowners are getting displaced. The idea of contributing to this doesn't appeal to me. How do I structure this deal while keeping the tenant?

I'm not certain what the current tenant pays but I 100% guarantee it's not the $1500/mo rent the house could get. It's likely $750-800/mo.
