Seller Finance - Wrap

[Tyler Brady]

Have a question that may be complicated... so I bought a property sub-to (current mortgage is 458k) I am going to sell the home on seller financing to a retail buyer for 699k. They will put 120k down amortized over 30 years with a 5 year balloon/refinance at 4.5% interest rate. I know how much ill make on the down payment but how do I calculate what interest income ill make monthly/yearly? and how do you manage the end buyer to make sure they do the refinance? I will be using a escrow company that tracks the payments, taxes etc..
