Is it fair for me to not have my own hot water heater instead of 3 apts running off same heater that is downstairs in a apr where their is alot of kids and randon people taking showers. My power bill is almost 100 due...

Transferring money between completely separate LLCs might cause you some headache in the beginning and not really benefit you how you want it to.

That being said, if you're a math guy and like numbers, there's no harm in running them.

We also had a plumber abandon the job (ask me for his name), which caused us a two month delay...The project came on the market in the winter of 2018/2019 which was a horrible time for the market.

I did 6 month rehab cause this is my first rehab.

You know they didn’t cause the damage.

Side note, I'm also considering refinishing the vanity top cause the sink bowl has some scratches in it.
