Real estate investing, modeling residential revenue. If we go to our workout tab, we're being asked to calculate the monthly gross potential rent, or GPR, and net rental revenue from the following residential building. We have a building that has four different types of units. It has monthly rent per unit. And we know the number of units of each type as well as the vacancy, free rent, concessions, and credit loss assumptions. So to begin with, we will calculate the gross potential rent.

So we need to calculate the number of each type of unit times the market rent for that unit for three bedroom units, two bedroom units, one bedroom unit, and finally, studio units.

The next thing we need to do is calculate the potential vacancy, free rent, other concessions, and credit loss for this property, and that's going to be equal to the assumptions we have here times the gross potential rent. And if we anchor the gross potential rent, we can copy these down.

The net rental revenue will be the net of these.
