I want to find out opinions on a subject to deal.  Property is recently remodeled and had a tenant renting for $900, property management in place.  Property was appraised for 90k and has a zillow estimate of about 103K.  I am asking $88k total price, $33k down payment to me and buyer takes over loan with a balance of $56k at 5.5% interest rate, payment is $512 monthly with taxes and insurance.  Any thoughts?
