The only information I had to go on was with the last Lender informed me so maybe it was specific to the company they were with.

Where do you expect to receive the money to buy out your "partners" in these companies as you drive returns into the ground? 

Say that $500k is invested in a new trade or business - now it is business interest expense. 

Within the first month I believe the company byte federal has a data breach.

Sure, they may be able to grow to a very moderate size,  add a few units, or trade up to a larger investment, but as for real scalability: NO.Why?  

I have learned a lot over the last ~6 months about furnishing a property, managing/pricing a rental, understanding the ins and outs of Airbnb/Furnished Finder, and analyzing real estate investments generally.My business idea is to use that knowledge and start a company that does the following:-Furnishes properties for investors who want to turn their LTR into a MTR/STR, new homebuyers who want to house hack, or just any investor needing a rental furnished.

But day trading is a job at best and a nightmare at worst. 

Anyone know of one?  State Farm just told me I have too many houses and have to move on. 

What is trading paper or contacts called?

I'm presently a facilities engineer by trade, who does some construction and maintenance for landlords on the side, hoping to get back into the private real estate game.
