I still don’t think you ahve it right. the 80k isn’t being “subtracted”, it’s being added in to make it look cheaper on the 20% up scenarios.
you wrote:
20% increase over 8 years:
$113,342.30 (8 years of interest) – $206907.76(equity) – 80k (down payment) = -$173565.46 (total cost of living in it for 8 years)
shouldn’t this be 207k – 113k = up 93,000 the 80 k isn’t profit to bring it up to 173k, it’s just money you put in that was there at the end of the transaction. kind of like if you’d left it in the bank. actually you’re only up 93,000.
