Wanted to post an update here, just in case it can be helpful to others! After all of the responses to this thread, and after speaking to a few lenders, attorneys, and accountants who specialize in RE transactions...I get a few things about this particular deal. First, in the grand scheme of this total transaction, this "outside" amount ($300K) likely doesn't really support an equity deal at all. I think that in the future if I am going to do an equity deal, in order for me to keep it nice and simple for all parties, one side brings all the money, and one side brings the deal and all the work. Next, you want to be sure that you aren't "syndicating" without applying for an exclusion, and you want to also be super clear with your lender about bringing other parties and other money into your deal, even if it is after closing. As I'm still in my early years in this business, I plan to keep it streamlined, as I don't want or need to share the management, or the profits (or losses!) just yet. I know I'll grow into equity deals in the future, as I do understand the benefits for larger projects. Thanks again for all the great advice and feedback!
