How AirDNA and others get the data so wrong I can’t say for sure, but I suspect it’s because they can only assume that unavailable days equal booked nights versus any number of different, non-revenue reasons, such as owners’ personal usage, repairs, etc. 

Purchased for $290,000, put 25% and put $20,000 in repairs.

Have the tenant sign a Lease Amendment indicating that the tenant is responsible for the cost of installation of the charger, any maint and repairs, and also removal cost (if desired later by you or the HOA). 

This is why most wholesalers are terrible because their numbers are never even close on the repair costs.

Make sure to budget for any repairs that might be needed. 

Find properties that are not listed on the MLS for the world to see, get them under contract, then assign the contract to an investor for a markup (but a list price that makes sense with the amount of repairs needed).This is not an easy job.

Co-hosting could be locally based i.e. delivering towels, doing inspections, managing repairs and maintenance etc, or could be virtual tasks like communicating with guests and coordinating things virtually. 

You can strengthen your position by documenting the repair estimates and the potential loss of income due to the disruption in bookings.

I faced challenges with unexpected repairs during renovations, but having a contingency budget helped mitigate these issues.

Someone other than her would rent $1650+ pre-renovation and after repairs monthly rental yield would be $2100+, 3.
