We share the area the property is on, the trash cans and the mailbox (should've been a red flag right there since how is it possible to receive mail from two different addresses into the same mailbox).

I'm active duty Navy andI'm stationed here on an aircraft carrier.

Market all properties with other insurance carriers. 

I have already signed the P&S agreement and now I am basically waiting to get fully approved by my lender and insurance company.My homeowners insurance representative told me the carrier would have an issue with the property being delivered 50% vacant (I am living in one unit and another tenant is staying as they hold a lease through January 2018).

I got a check from some business address, which tenant should not be related to, in my name for that amount.Is it a red flag or can i accept that check as form of payment on behalf of tenant.

Way too many unknowns if some are off - and the fact that you're not allowed to turn the water and power on should be a flag to you.

The business expenses you take to offset your gross income will be less likely to trigger a red flag to IRS for audit and 2.

And when someone tells me that they have to move because their landlord is selling...it's a red flag.

Big Red Flag: Why exactly don't the crowdfunders want this?

Also, get in writing from the agent that the carrier is aware of the knob & tube.
