Found seller who owns property 100% what to do next to secure seller financing?

[Mike Barry]

Hi everyone,

I'm new to the aspect of seller financing and looking for a little advice here from pros. I've been able to find a seller who owns a 2 unit duplex clear and full. I'd like to try to secure seller financing as my debt/income ratio may prevent me from securing a loan the traditional route. The seller has mentioned wanting to use the money to put as a down payment on a property a few towns over with a better school district for her daughter. When I mentioned the idea of seller financing she turned it down because she needs the money in full upfront for this reason. 

She does not plan to relist it on the MLS, but she said she has no problem keeping the property as it cash flows quite well. Has anyone been in this position before, and if so what would be a good way to approach this to secure seller financing?

If seller financing does not work out do people find any other advantages to working with for sale by owner instead of using a an agent/MLS?

Thanks everyone in advance!
