I don't know about all the requirements for individual operators, so you need to talk to the companies about that. I suspect requirements are somewhat flexible, depending on need at the moment. At the moment, need is high.
As crop duster said, the housing the companies offer is for employees only, and not that elegant. You generally get a small twin-size bed, a private room if you're lucky and share it with another pilot if you're not (
AFAIK you don't have to share a bed at any company, though). The bathroom is always shared with at least 2, maybe more, rooms. Don't even think about putting your family in there, if you care about them at all.
The fall shouldn't be much different from now - the pilot shortage isn't going to be over for some time.
