I guess this also depends on how many rentals you have and what features you require in a PMS.

Since owning them, we have installed features to store over 5,000,000 gallons of water in the soil that did not exist before.

Here is an examplePlease let me know if there are any feature which you think might be useful and would like me to add to the extension.

And what is a "mileage book" anyway in the age of navigation apps?

I was not able to find any recent comparisons in the last year and since features and pricing change over time, wanted to share my research. 

The app doesn't allow rent by room, so I am sort of forcing it.

If you don’t have one already, try adding a video or virtual tour to attract more interest.Make sure your photos are high-quality and show the best features of the home.

Every system you try will have flaws or you'll salivate over a feature that shows up in other software.

Along the same lines, the buyer who can barely qualify for the entry level SFH is acutely aware of their cash shortage and therefore are going to be less accepting of household features near the end of their useful life, even if still functional and have a stronger desire for anything that is listed as a deficiency on the inspection report to be corrected.
