Second, I will talk about selecting good comps.Suppose you are considering the following property.You find two recent comparable sales, which are listed below.The process is to determine the average $/SF of the comps and multiply that times the subject property’s SF. (238/SF + 235/SF) / 2 = 236.5/SF. 236.5/SF x 1847SF = $436,815.

A big chunk of that return is typically coming at sale or refinance of the property.3 - Equity multiple: Equity is a fancy word for cash, if you put in $100,000 into a real estate deal you’ve put in $100,000 of equity.Equity multiple projects how much you’ll multiply that investment by over the life of the deal.

Material cost Multiply by 2 to get the labor cost.
