Uses your "current avg rental rate" inflated 2%/yr. If that rate falls short of break-even, the shortfall is added to your total invested; if it exceeds break-even, the surplus is added to your returns. Property appreciation: 2%/yr. Operating costs inflate 2%/yr; mortgage P&I is fixed. Horizon runs until the loan is paid off (extra payments shorten it).
