This was sudden and no previous communication on listings that have hit their site previously.

Communication is challenging, most likely uninsured, but this is in-line with the budget.c) Keep searching for contractors, adding time to project and potentially costs.d) Buy scaffolding or rent scaffolding or a lift and demo myself for under $1,500, including dumpster.What would you do??

Might be time to look at other options ..We have good communication and they are very knowledgeable but might be over extended working on other properties . 

He has also played a key role in facilitating communication between the new tenants and myself, ensuring a smooth coordination of arrival times and addressing any specific needs they may have.

The company that has the best communication of the DST's that I have is Passco. 

Are they communicating with you all the time with updates etc? 

Communication is key!

I am about to submit to the IRS my log of 500+ hours working in the STR business, most of which come from communicating with guests, cleaners, maintenance people, Airbnb, VRBO, and managing supplies, shopping, bill paying, pricing, calendars, all the daily and weekly tasks. 

They immediately stopped paying rent and stopped communicating.

Get the lingo down, see what others are doing, see how the communication is, listen to 100 pitches for LPs, get on the deal flow lists, get on some property tours. listen to the podcasts for 2-3 months.
