I have managed 180 unit buildings and currently oversee a student hosing building for 201 students.

Contractors.Except we called it " buying a beat up hose & selling it for a profit"HGTV and GURUS  couldn't make it sound trendy though  ROFLMAO

Unit 2 uses the hose to wash his car every week for like an hour.""

I am going to install a hot/cold hose bib so they can bring it up to temp more quickly.

A simple example is that they called to tell me the hose was left on in the pool.  

Somebody is getting married so slaughter a goat as part of the feast, in your apartment, your 2nd floor apartment, and then wash the gut's and gore into hallway via a hose tapped to kitchen faucet to "clean up", the CARPETED hallway, carpeted apartment......

Someone with a good shop vac that has a long hose can get it cleaned out pretty easily. 

They have all utilities on the property so we use electrical and then every couple of weeks we run a water hose to an external tote we use for our water.

Starting with a heavy rehab BRRR's would be kind of like drinking from a fire hose.

Although my cost of capital was cheap (2.5% 30yr fixed), the increased STR supply resulted in a more hands-on approach by me (better marketing, improving the quality of my check-in hose, services, etc) and this wasn't turning out to be as 'passive' as I would have liked (I've been managing my own LTRs for close to a decade, so perhaps I'm spoiled).
