Investment also spiked in Class A Short-Term Rentals (STR) and investors started paying higher and higher prices based upon anticipated STR rental rates, that exceeded sustainability based upon Long-Term Rental rates (LTR).

Should they have communicated better?

Based on your response Katee you clearly have not read through my comments in any detail or tried to understand my perspective or concerns.

am working with them now and had the first policy (with Spinnaker) cancelled for nonpayment/late payment so we rewrote another policy (with Millenial) and having the same payment problem again but at least they are communicating that cancellation is coming. they want me to pay by credit card over the phone so the payment wont be late and cancelled again. but when i go to mycoverageinfo.com to check on status it shows its been paid.

I have been kicked out of every form of communication relating to this deal.

Not blowing off their communications and things like that go a long way.

Airbnb is very algorithm based and despite the popular opinion its not hard to stay in good standings on the algorithm. 

You may want to make an introduction between your CPA to those 2 colleagues.The CPA can go over their services and pricing to your colleagues.I partner with many people on real estate deals - It never gets to a discussion on whether they do their own tax return or hire a professional.If a partner mentions he will provide capital - does he provide the capital on a timely manner.If a partner mentions he will find deals - does he find many deals and provide an analysisIf a partner mentions he will manage a property - does he manage the property well(find tenants, collect rent, communicate with contractors, etc)

If they find out you've communicated off-platform with a guest like this one is requesting, they may boot you off their platform. 

As the property manager, it concerns me that the software does not allow me to select message timing and verify content of communications that are sent directly to MY tenants.
