I'm sure you'll find that this is a fantastic community of people who are glad to help out.

In some jurisdictions you can drain the gray-water into a flower bed.

When I went to enter the apartment to ensure the outlets were working again I was greeted by her dog (deposit paid) and a second large dog of which I wasn't aware.

That you wisely build in the costs for replacement linens and towels (also offer black face towels), possibly don't use high-end top-down shades in the Bunk Room (although those black out shades match all the shades in the rest of the house and it's a high-end property), chalk can be brushed, semi-gloss on walls for easier clean-up... and yes, there are clear check-out directions to run the dishwasher provided via an online guest book, a physical guest book, and an email I send regarding check-out the day before they check-out.

Somebody that really wants to get in can still do it, but it might help provide peace of mind for tenants.Those size A/Cs will run on a regular 120 V circuit, but you might look around to make sure there are outlets close enough to all the windows you want to put them in. 

This usually involves fresh mulch, flowers, etc. 

Most other electrical issues such as lights not working or outlets can be fixed pretty easily so I wouldn't worry about those as much.

You’ve been able to maximize all available outlets for income.

I would argue that not only is it possible to make money if you don't rehab yourself, it's absolutely necessary that you don't do the rehab yourself.Unless you are a licensed contractor, you shouldn't be doing things like removing walls, installing ceiling fans, swapping outlets, replacing windows, etc etc.

Some of the things that have happened during the last 7 years of running STRS, loose deck boards, rotten outdoor steps, broken interior hand rail mounts, loose electrical outlet...Any of those could cause a major accident so they were repaired asap.
