Analysis tool for the mac

[Josh Gesler]

I've used a simple spreadsheet to do quick analysis of prices vs rents using the 50% rule. I'm working on making a Dashboard Widget of it so I don't have to leave the spreadsheet open all the time. Is anyone else interested in using it? I'm happy to share.

It will calculate the following:
Input: Monthly Rent, Expense Ratio, Desired Cashflow /month, Term of loan, Loan Interest Rate
Output: Maximum Loan Amount

I've also thought if there was enough demand I could create some other tools for investors. Any suggestions? I'm also toying with idea of creating an app for the Palm Pre and maybe the iPhone.
