Is it possible, yes.
Will it take work + time, definitely yes.
The key is that this is a relationship business. A human business.
For 100% financing, you will want to demonstrate that you have management under control through your team. This includes any rehab construction and property management. To help your funding partner make a quicker decision, try using a credibility kit. Here's a good thread on how to create one:

Also, you can send a "sample deal" and ask, what do you think of this deal, and get their feedback.
It is consistency of communication, so it may take a few tries, but start building up the relationships now with your lenders/partners.
Post your deals everywhere and build up a list. There are lenders out there (especially moreso in today's market than 2008-2011) who are looking for trustworthy people who can make their money go to work. (See the book Rich Dad Cashflow Quadrant... I = investor, who wants their money to work for them). Your goal would be to service this group of individuals.
I would also try to focus on motivated sellers who can do seller financing and get your investor to cover the down payment or half of it, then use a business line of credit for the remainder.
