Some companies will keep a certain amount of money for quick/emergency repairs, but in general you are responsible for keeping your own maintenance/cap ex reserves in an account. 

I think I get the spirit of your question, but May 2021 rents is a fine thing to get excited about if you don't own any property now or sit on substantial reserves.

The ones who can repurpose their units as long term rentals may be okay if they have reserves to bridge the gap in economic activity (who's moving in the next month or two?)

During that time, I have also been incrementally increasing my cash reserves and I currently have enough to cover any expenses for at least a year in the case that I can't find a tenant and the property sits vacant.

. $2500 is nowhere near enough money to have in reserves if you really want to get involved with real estate - it's just a capital-intense game.

I recommend, do not over leverage yourself, keep a cash reserve. 

On-line brand recognition is high, resulting in 67% direct reservations, 17% via Air BnB @ 3% commission and 16% via Booking.com and Expedia @ 15% commission. 

The kits they sell at the big box store do not work.

You want to have cash reserves now to survive the bumps in this economic environment.
