Thank you for providing such a great product (Ultimate Investment Property Calculator). It has phenomenal amounts of potential and applications, and it has really helped me clear up a few cashflow questions I had in regards to building a property portfolio.

As a property investor I find the tools (Ultimate Investment Property Calculator Package) I have purchased from you to be the very best to date. They make dealing with multiple properties easy and they allow you to very quickly analyse what is happening with the properties over time. I very much appreciate the Management Spreadsheet (Investment Property Record Keeping Spreadsheet), which I use the most and it is now even better being able to tailor it to my own circumstances.

I am extremely happy with the service and support that you have given now and when I first purchased the software and whole heartedly recommend you to anyone who will listen.

Thanks for your help, your investment property software (the Investment Property Record Keeping Spreadsheet) has made my life so much easier. I have quite a few properties and now all my expenses and incomes are all in one place. I think my accountant would like to thank you also. Now I can give him an Itemized list on each property with little or no effort on my part.

I think the best part of the software is the support you provide. Every time I either had a problem or a request for some assistance you supplied me with a fix or a solution within hours or even minutes.

I would definetly recommend this (the Investment Property Record Keeping Spreadsheet) to anyone that has rental property.

I am absolutely delighted with Patrick’s spreadsheets and customer service. I rate both 10 out of 10. I first tried his free Investment Property Calculator and liked it, but I wanted some changes to suit my specific needs. He made them without any fuss so I purchased his Standard Investment Property Calculator with the modifications. It did everything I wanted and helped me make quick decisions in the marketplace. A year later I tried his free Rental Property Management Spreadsheet and liked it but again I needed some modifications which he made quickly. I purchased it with the modifications and I wouldn’t want to manage my properties without it.

I'm really enjoying it (the professional investment property calculator) so far. My wife and I are currently using it for scenario analysis on two houses we want to buy next week. - Massive timesaver using your calculator.

All the calculators are built with Microsoft Excel worksheet. You need to have Microsoft Excel 2007 & above and Microsoft Windows to use them. You may be able to use the calculators with other applications that can open and read XLS spreadsheets, but this has not been tested.

All the Investment Property Calculators are built for residential properties but not commercial properties. Using the Investment Property Calculators for commercial property investment (e.g. retail shop, office etc) is at your own risk.
