LOL so as you pay the mortgage down, you get to keep more of your rent? really?
And as your rent gets biger because of inflation, so does the price tag on the house, its still the same % return on the same item of same value. buts there is more $$$ as $$$ are worth less due to inflation
Only way your rent collected gets more VALUE is if the VALUE of the house goes up, not the price with inflation.
Just like if the VLAUE of your house does not keep up with inflation you become poorer, even though the price of the house goes up.
Amazing how some people cant get their head around basic 1st year economics.
