Not sure if I understood this part correctly (and not having dealt much with US Financial Institutions on mortgages I may be in the dark on this) - are you stating that:(all numbers for sake of illustration):- 2010 I take out a 15 or 30 year fixed mortgage on a property for 100K; 20K down, 80K mortgage (20%)- 2015 property is now worth 200K; principal paydown was 10K on original mortgage - i.e remaining mortgage balance is 70K.
