If they've already started the legal process then call your insurance and stop any communication with anyone else.

Clear communication is key if you are doing these kinda of deals if you want people to work with you long term.

Maybe my communication was poor.

We do the work, you earn the daily payouts as the renter pays.We specialize in long term rentals so its pretty common have one renter for months at a time.Based out of South Atl, Ga, we house and operate your vehicle out of our Club House where we handle the maintenance, daily communication with renters, and paperwork! 

If rents are declining, to keep the property full at current rates I would keep the rate flat.If they're good tenants, charge them a short-term rental premium but dont' give them a huge increase for the 6-month lease.In these cases where it's a 1:1 tenant/landlord renewal, it's best to communicate with each other and reach a win-win

I'm thrilled that we've grown to this point in our portfolio, but we are now up to 10 single family homes, and with other (more than) full time jobs, we are desperately looking for some help from someone that can help us track rents, walk throughs (property upkeep), etc.We have done an excellent job up to this point, but it is not sustainable, since we travel for work, and our tenants need more communication/attention.Any suggestions/thoughts here?

Relationships and communication are EVERYTHING.

Communication, process and certainty of execution are key. 

Smart, excellent negotiator, great people instincts, communicates the way I want.It does not matter what car they drive, what they look like, or the bells on the website.

Plus it integrates with your calendar so the communication between you and your cleaner is minimal as they just know when they need to get in and clean.
