yes you can, because everything is an opportunity cost. when you buy a house, you are making an investment, with the cashflow being the foregone rent. my condo that i live in is $850k, and the net yield is 1% for the landlord. if i got $850k right now, and i bought the condo, i'd save about 8.5k in cashlow. if i bought td stock, another stock i own, i'd be earning almost 50k in a cashflow. i could then use that 50k to pay the rent.
