Should we have a joint bank account separate from our own strictly for the REI business to keep track of funds and cash flow recycling and etc?

Is the paycheck deposited to a bank account that could have an auto ACH to you on payday?

Dogs and cats pee on laminate, hot-water humidifiers leak on it, kids start wet-mopping it when they spill something on it that they don't want Mommy to see, tenants turn off the heat when they go somewhere no matter what you write into the lease, and the stuff swells at the joints.

Our plan was to pay off our loans as fast as we can, start a corporation to mitigate risk and start a joint savings account where we do 50/50 contributions to build up cash to invest. 

They had already been fined $260, sent certified notices, and a court was being filed.They claimed they where switching bank accounts and because of that they could not pay rent with cash, check, ACH, or credit card... one quick email to them from the pm saying if they did not pay rent, their car would be towed, we would freeze their accounts, garnish their pay checks, and have the police remove them from the property by force if rent was not paid by 8am the following day did the trick.

Our activities for 2016 consisted of two joint ventures.  

Can't tell my mortgage company sorry, but Rentigo is having problems getting ACH to clear.

I would recommend reaching out to them to see about doing some kind of joint venture.

Here's a little backstory 1 yr and some couple of months ago, I was at the Joint Base Lewis–McChord library in Washington State.

You put them all on one lease and make sure it holds them jointly and severably liable.
