Don't know if it is a good one but I made one for myself in Excel.

It only goes to Johannesburg -> Auto Junkyard but you can easily add other property. Just enter the name and change the original cost in column Q and the income in column F. If you allready own property in Bangkok or higher and you don't know the original cost, you can calculate it:
(current cost x 10) / (amount owned + 10).
To use the spreadsheet, just change the amount owned in column J.
The best buy of the moment is highlighted in green in column H (current cost/income).
Edit: this is for Insomniac, I don't know if the price and income are different for Tycoon and Bulletproof. If so, change columns Q and F.
