If I sold a home for $200,000 after living in it for 13 years and I had $166,000 costs in it, including cost of construction and real estate fees what interest rate did I earn on the property? ... Just simple figure not counting cost of living changes, etc.

Int. = 200,000-166,000 = $34,000

%Int = (34000/200000)*100% = 17%/13yrs.
APR = 17%/13yrs. = 1.31%/yr.
