It has provided multiple 6 figures in equity since. 

The interest rate is about 8.5% but the cash is accessible within weeks and we would only have to bring 10% down for our skin in the game.

Your CPA should provide the details.

There are some missing pieces of data needed to make an in depth analysis from where we sit and give you more sound advice, however I own/manage property in Tampa which is a highly producing market and:- With $300k to play with you can acquire a $1M property or more which does provide the best cash flow- On a $1M acquisition and $200k (or less down possible) you can achieve 10-30% CoC returns, likely 15% inclusive of management is possible.- Do not forget about appreciation, which is where the real wealth comes from. 

Here you will meet wholesalers who provide deals and rehabbers (cash buyers).

Lot's of different ways to skin it.  

Ask questions, get to know the renters, and document the condition of each rental so you have a record from that point forward and can hold tenants responsible for damages.Your offer to purchase should include a requirement that the Seller provide all documentation and agree to sign an estoppel certificate (also called an estoppel form or agreement).

>> Are there other deal structure that I can present without I bring any fund and will only provide the value and management?

What we do different from anyone else we've been able to find, is actually provide complete transparency into the process from the purchase of the deal, the entire rehab including costs, renting out the property, and the refinance process (most of our deals are BRRRRS).

Always make the seller provide title insurance.
