@Shawn Tuma definitely depends on the number of units to a certain degree but PM software is great for a number of reasons, some of which you stated and others you didn't.1.

We are using Guesty software to set our pricing adjustments for seasonal and far future vs near term, but maybe its a little overkill for MTR. 

@Madelyn Felix I would look into showmojo or tenant turner for their lockboxs and self guided tour software.

In reference to you concerns with permits, I went into our Property Management software Appfolio and looked at the property information.  

The same way people buy into a CRM software.

What kind of software do you use if you don't like to drive for dollars  ?

We use accounting software that codes the income and expenses to the property (called a class) so we can run P&L;s on each property with ease.Your accountant and bookkeeper will also thank you later for keeping it simple and avoid significant accounting costs. 

@Yixin Huang we use a property management software which keeps the communication centralized and updates them on status. 

Based on my experience, you either pay some more but get a high-quality service, or you have really raw but cheap software.
