Last I am looking to to move my real estate brokers license to an affiliated business or connect them in some way. 

At the very least, your few thousand dollars a year saves you the dozens of hours that you'll spend trying to to stay on top of all these tax rules as they apply to your situation, understanding the nuance, and also filing your own return.

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

IF your QI doesn't do that then you got a whole heap of other problems.Ir'a nor going to to just get swept under the rug so take that lender with a big shaker (not grain) of salt.The way to do this is if the Carriage house can be considered a second dwelling with it's own address. 

@Paul Xiong there isn't enough info to say for sure but lenders can use 1 yr on bank statement lending (use your bank statement deposits and withdraws to qualify for income) with Verification of Employment.

You didn't mention anything about the Verification of Rent for their last 2 landlords?

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

This should include credit checks, reference checks, and employment verification.

I think it would be easier to to buy a new build then take equity out after a year or so to purchase your another rental.

He had moved so he never got the notification but his address verification checked out so I took the chance.
