The IRA funds would not be able to be combined with other personal funds as in your note above. 

Fingers crossed in 7 years I have not had to test my coverage, but in the area of my rentals a golf cart is expected with the rental.When they crash into someone else, did that person sign the waiver too ?

It doesn't sound like this "statutory agent" is an "agent" as we understand in normal course of day to day life where the agent can bind you with their actions.

I look at the whole person.

Note ADU addition in a MF zoned area may be comped with a duplex but I personally think this is wrong as a SFH with ADU is not a duplex.- it is cheaper to buy a property with an existing ADU than adding one   In addition you would receive RE purchase financing.  

@Yanina Panfilenka Welcome to BP & the RE Investor Agent Life.

Lastly, our DTI is maxed out per every lender we've spoken to recently as all the properties are mortgaged in our personal name.

What happens if one of you decides to buy a personal home and need the credit to qualify for a new loan so needs to sell this one to make it happen, but the other partner not ready to sell yet, or doesn't want the capital gains. 

The total cost of project is more than we can qualify for based on personal income, although our W2 income and credit score all work in our favor.

I would personalize it with a picture of yourself and sign the bottom to make it official.
