There are a lot of great options out there; aside from providing the basics (ie. listing tool to get the property published to 10+ major sites, scheduling tool to schedule viewings, tenant screening with comprehensive applications which include nationwide criminal background checks + credit checks + eviction history, digital lease creation tool, rent collection tool, and maintenance tracking tool), some services also offer your tenants additional capabilities which makes it an easier sell on your end when getting them to transition over (ie. all of the other tools in addition to their ability to report on-time rent payments to the credit bureaus; this can create an added incentive for making sure they pay that rent on time).

A desire and ability to share their knowledge4.

Second, it gives me the ability to easily see true income versus expenses in order to make informed management decisions.For our STRs, we used property management companies that collect and remit sales/occupancy taxes, so we don't enter any of that info into our accounting package.
