It’s the most robust and customizable CRM on the market and can include parsing by areas/location.

It’s quite customizable and fairly intuitive.

It's electronic, free and completely customizable.

Very powerful and customizable.

Very user friendly, customizable, and can track all your business ventures separated by "class" which is basically categories you set. 

@Oliver Evans Podio is a great customizable option.

On the other end of the spectrum, if you want the best and most complex money can buy, you may want to consider solutions like Yardi, Appfolio, Buildium, and several others that are completely customizable, but expensive. 

Hello all,

Is there a rental property management software that would allow me to customize my own rental applciation instead of using their standard application? Does anyone recommend a specific software?

Thanks...

Some of the partners I use charge no points, a 7-12% interest rate, up to a year, and otherwise customizable. 

Hello, I really want to have my rental application to be online and customizable to my own liking with the ability to choose the credit bureau I get my credit checks from.
