New idea for a tool?

[Eric Lee]

Generally speaking, I see the majority of real estate analysis done using the deterministic approach we're people essentially use assumed averages to evaluate a property. In other investment realms such as corporate finance or stocks, people often use a probabilistic approach where each variable has a range of outcomes that vary along some distribution (i.e. normal/bell curve, triangular, etc). Considering returns are often non-linear and affect of compounding money, I think this approach would be more widely used.

I have been exploring writing a program to do a program to do such an analysis. The tool would be able to do myriad analysis to evaluate the deterministic analysis such as margin of safety, probability of a return, maximum buy price given a certain probability of a return, and calculate the opportunity cost comparing this investment to an equal investment in an index fund.

Does anyone think a tool like this would be useful and beneficial or do you think it's more of a waste of time? Would anyone be interested in a tool that could do this?
