I'm far from tech-savvy, I think when I set it up, I needed to run it through a PMS to make it work, however, that may have been a function of having 2 properties instead of 1.  

I’m especially curious whether these functions are handled:In-house by local staffOutsourced domesticallyOr handled remotely by trained team membersIf someone were well-trained in property management operations (screening, maintenance coordination, tenant communication, AppFolio/Buildium, etc.) and able to work remotely from Mexico, is that something you’ve:Already implemented?

First one must have been on meds as it depended on what day you talked to her as to what reaction you would get, the second moved out one night with no warning and the third . . . well that is the lesson to share.When we listed it for rent, we posted it on Zillow Rental Manager and used their background screening function as it allows potential tenants to apply to multiple properties and landlords get a report. 

Those operators don’t function without reliable cold and frozen storage nearby.You’re also right about the all-or-nothing nature of the model.

If a property qualifies for conventional financing (functional kitchen, bath, working plumbing, etc.) you could absolutely move into one of the units, rehab others, and get the value add required to create a deal.

What I like most is that they are a fully functional accounting and payable system.

The search function leaves much to be desired, but you'll do best searching "FlipSystems" as one word:https://www.biggerpockets.com/forums/79/topics/1182640-lesso...https://www.biggerpockets.com/forums/67/topics/1204806-seeki...https://www.biggerpockets.com/forums/48/topics/1098187-flips...https://www.biggerpockets.com/forums/79/topics/1188268-flips...https://www.biggerpockets.com/forums/92/topics/1181695-is-fl...I admittedly have not read every reply, but it seems like a sea of red with "Amy B." being the only positive sounding reply on this thread: https://www.biggerpockets.com/forums/67/topics/1174732-calli...Is that the person you spoke to as a reference that's his girlfriend?

OP use the lookup function.  

Once you have a short list, get an account with each one and run them through the wringer to see how they really function.

Use the search function to look up topics and locations of interest.2.
