100% financing, 50/50 split, by experienced & licensed broker

Would it be reasonable to assume that a deal is worth pursuing with a residential real estate licensed broker, who is resident of SW FL for over 20 years and looking for cash investors to buy qualified multi-unit properties in Florida? What if the broker offers to pull permits, rehab, find tenants or sell at market prices for a 50/50 split and turn around in 12 months (from rehab to rent/sell, exclusive of permitting)? What if the same broker had stellar local reputation, was an expert in budget home repairs and home staging for sale or rent? Would you do it? Please advise.
