Help me explain Seller Financing to Grandma!

[Jim Sestito]

Hello BP,

Dear Grandma is looking to downsize.  Her house completely paid for and she has one note on it that she used to purchase a car with a about $18K remaining.

The house is a two family.  The  main unit is a 3 bed 2 bath (she lives in this one) and the apartment off the side is a 1 bed 1 bath (Just became vacant Jan 1).  The house has a nice yard and a separate garage spot for each unit.  Both units need updating to get full market rent for the area but are currently very livable.  

Roughly $370,000 ARV --- Needs about $20K to get there.

Grandma is about 80 years old and financially secure.  

I somewhat understand seller financing from the podcasts and various BP searchers.  But I would like to hear the best quick Grandma elevator pitches for this situation.

Why would this be beneficial for her?  Why is this beneficial for me?

If any needs more info please let me know.  Hoping this will be a fun thread!

Best  -- Jim
