Quote from @Geeta Bihari: Cash flow will be a function of how much money you put down/amount of leverage you use. 

What are the functional issues? 

Make sure any lender requirements—cash management, carve-outs, reserve controls—still let you function as co-owners.

Are there any other people currently prioritizing design over income/functionality (that isn't already a multimillionaire)?

The BiggerPockets community is filled with people who can share valuable insights and past experiences.I'd also recommend using the search function to find people and topics of interest here on BP.All the best to you!

I always focus on exit mechanics: rights of first refusal that actually function on a timeline, an appraisal method everyone accepts in advance, and a pre-agreed path to sell or buy out without torching value.

At the heart of it, a big function of cash flow is the principal and interest payment on the debt.

All are perfectly functional now, but could pull higher rent with replacing the flooring, and updating the kitchen.My current financing setup for this deal would be $235,000 from the HELOC I already have secured.

The function provided is limited, they provide labor and labor management.

They have given a standard and this is not a legal matter it is a functionality for the house that tenants look for in the property.
