What return are you getting on your money from paying down a mortgage on a rental property?
As Chris pointed out: If your expenses are covered by the income exactly, as you have said to assume, then you are basically starting with a $40K asset (your starting equity), and ending with a $200K asset (a paid for home, at the same value since you have said to ignore any appreciation). So, to determine what you have earned on the $40K you leveraged 5x, wouldn't it be a matter of computing a CAGR that gets you from $40K to $200K in 30 years? The result would be a nominal return, not a real return. So, if I set up the problem correctly, it should be: $40,000 * (1 + Return)^30 = $200,000 Then solve for Return. It works out to be about 5.51% or so.
