Part of what makes them good salesmen obviously. 

My total credit utilization would remain < 30% after taking the cash 3.  

You are obviously ticking them off and will only make it worse. 

The foundation was noted as good, and the foundation in the basement doesn't show any obvious signs of problems that you might typically see with foundation problems. 

I'm not sure how many total properties you own but rent-ready and buildium are worth checking out as well.

Also a side question: Do you buy Umbrella policy coverage amount 'equal' to the total amount of all your investment properties and personal net worth?   

I would suggest to check with your local laws first.Most likely you will need permit ( I guess you can get away without, obviously not suggesting that :D)) but possible) , also check your zoning.If not possible to create separate unit legally, I suggest not putting an oven in the basement, and rent it without, or live in it yourself

Maybe this is obvious but we are sleepy so appreciate the help.

I didn't realize this.I know you aren't on the lending side per say, but follow up question.If I have two buildings in my name with total debt of $900k and I am looking to refinance one of them that has $500k debt, would the 45% DTI be based on the total debt ($900k)?

Also your risk profile and total net assents in each LLC matters too.
