You and your partners are going to do nothing but put food on the table for your GC, Agent & PM.

You may get it, but the table shows the maximum they will pay.

Our bank will let us use equity that exceeds 25% across multiple properties that are either owned free and clear or where they hold the first so long as the deal still cash flows with however much cash is brought to the table.

In my humble opinion, if you want low, competitive rates, fast closings and great service, work with a broker.I'm also an investor and have been on the other side of the table. 

Yes, long-term rental clients sometimes don't want short-term rental next door to them, but you are the owner and landlord and set those expectations up front so it's on the table before they lease.

If you don't mind my asking, how did you find the deal to begin with, and did you have some hint that owner financing might be on the table from the get-go?

There is a "sponsor exemption" but that only allows an unlicensed person to raise money but it cannot be more than 50% of their duties and the pay they receive cannot be based on how much they raised.If you have never raised $, a family office will be off the table as they typically want the company to ahve atleast $50-$100M in assets.
