Is it a bad idea to invest in properties where you would be able to collect rent that is equal or a little less than your mortgage payment?

This is the 2ND month the same problem is happening now, we have been with Appfolio for more than 5 years and have about 60 - 80 units collecting rental income through Appfolio and we never had this issue before with the previous Appfolio team.

However, much of our document and data collection was handled by loan analyst Taylor Vassey.

I don't necessarily need the standard features of pm software, such as rent collection, bookkeeping and maintenance requests, though that could help; but do need a clearinghouse of important information, such as leases, legal docs and other information; maintenance vendors I use; maintenance history; and some kind of tracking system, where I can record the various current projects I'm working on within the business.

They aren't sophisticated investors.
