Less down almost always = higher interest rate.Second part is raising the equity from investors.

"Upon termination of this lease, tenant shall continue renting on a monthly basis until either party serves the other with a 30-day Notice in writing."

I recently settled a multi year law suit that mostly went my way (not as much as I had hoped as the other party was scum).  

The way more challenging part is #1 finding the deal of course, #2 finding great contractors that would take on this type of project with payments to them working through installments, #3 finding great terms on your refi.My advice would be to look aggressively for #2 and #3, so if you do come across the golden ticket of #1, you are ready to pounce. 

The owner shall also post a notice of intent to sell at all public entrances to the property (that form will also be provided by DOH).If the owner receives an offer from a third-party, the owner shall provide a written notice to the DOH, tenant association or to each tenant in the rental property.

I guess I’m confused by the skip tracing part? I

Most of the crowdfunding platform operate like Craigslist ads and simply connect investors to third party sponsors.

Not to mention, you've now become reliant on a 3rd party for income streams, and yes, they do occasionally run short of funding and, yes, they have no compunction with telling you to pound sand until they get new funding. 

I know in California it is legal and the state acknowledges it however it does restrict the finder to basically introducing the parties and they can not participate in negotiations, etc.

Any deposit should by held by a third party in escrow.
