Evaluate real estate investments in Excel. The Real Estate Valuation Tool for Excel allows real estate investors to evaluate the economic merits of one or more real estate investments by calculating and analyzing expected cash flows. The software can be used to evaluate a single real estate investment, but its real benefit is the ability to compare one property to another. Users of the software may customize the analysis based on their views on each property and on the overall real estate market. Developed by CFA Charterholder.
