Unit 1 where we live has a basement that’s rented out on Short-term rental/Airbnb (with average stay per person < 7days).

I'm guessing 5 acres of land that's worth 4k per acre isn't going to be very easily to liquidate. 

Personally, I'd charge an early termination fee and find a new renter. 

Well, first, their is a base annual fee.

L.A. has had the worst response rate for us in terms of qualified leads generated per mailing.

IIRC they run about $25 per outlet, etc.  

You can automate your self and spend 15 minutes a week reviewing pricing in your market and adjust as needed.

Secondly, who cares what the ownership splits are if the gain can't be realized because the values are propped up/can't meet projections, the sponsor cannot execute on the business plan or the fee structure severely eats into the distributable cash when the realization event actually occurs.

Ask your Agent to read the notes and check HOA fees.  

Not if that neighborhood booms and price per SF doubles...then who cares?
