Net present value (NPV)
This is how much the NPV of using mortgage is higher/lower than the NPV of buying with all cash. When investment yield is higher than mortgage rate (APR), your NPV of using mortgage is normally higher than the NPV of buying with all cash, assuming your PMI is low. This is becasue your investment income is higher than the mortgage interest, and it brings you more cash inflow in the long term.
The winner plan
The better Plan you should consider is the one with the higher NPV, it brings a better financial outlook in the long term.
