@John Prunier Hey I'm asking the questions here! - No kidding - those are great points. This is my grandmother - she is financially secure - still works bc she loves her work - but does have three children who I am sure will be interested in any activity of the home.
My key purpose of posting this was to confirm the benefits of seller financing to the buyer and to the seller.
I could get a conventional loan but as @Ben Nelson stated one less loan on the balance sheet - not dealing with a bank - being able to create the terms myself. Benefits for grandma is she is getting cash (I would certainly give some down payment so grandma can have somewhat of an instant payday) a check for 1,400 - 1,600 a month that is 100% passive.
@Steve Vaughan She doesn't need cash. This is truly a case of the house is too big - she doesn't want to be a landlord anymore (although she rented the apartment for 25 years and never had more than 2 months of vacancy and never had one eviction) Doesn't want to deal with landscapers and plow guys to maintenance the house.
I guess the question remains how do I bring this up to her children - how will it work if the note lives longer than grandma. I am sure it could work out that the payments would go to an estate for the kids they could divide.
Thanks for the feedback thus far and would love to hear other stories if anyone else has done a similar deal.
