If you're unwilling to charge a common fee, I wonder how you're going to handle a problematic tenant who is late on rent or responsible for paying the plumber to remove a kid's underwear from a clogged toilet.How will you conduct a credit/criminal screening without an electronic application?

Typically turnkey operators are not in C/D areas so price to rent ratio is not working in your favor. 

@Nadir M. you would show 100% of whatever you collected on behalf of an owner.Of course, if tenant pays via credit card, you would NOT include the credit card fees, because you did not receive them.From the funds in your OPERATING account, you would pay any expenses on behalf of the owner, including your management fees - which you woul transfer to your PMC account.Owner will be paid from Operating account.Your vendors (office expenses, auto, etc) would be paid from your PMC account.Year end, you are require by IRS to send a 1099 with GROSS amount collected on behalf of owner.

Using mortgage debt at 6-7% on a refinance to pay off higher rate debt such as a credit card at 15-25% is a savings!

I am not familiar with Avail and whether a LL can view credit history.

Paying our investors 6-8% Pref. then proceeding to a 70/30 waterfall split in our favor.

$40,000 x 25%(assuming a 25% interest rate on credit cards) = $10,000This is more than the annual cash-flow that you are getting from the rental.I would look at a way to paying off the credit card debt asap.Look to see if you can take a HELOC on the investment property(likely difficult).If you can't you may want to consider selling the proprety.You will also feel a lot of relief of not having credit card debt hanging over you.What is the interest rate on the car loan?

Focusing on building knowledge, credit, and some capital is key.

Quote from @Matthew Beninate: Quote from @Sarita Scherpereel: Quote from @Seo Hui Han: You may want to consider local banks / credit unions just because many of them will require or give you more favorable terms for things like HELOC's and other line of credit products if you have a deposit account with them. 

Raising the  amount required to buy your target properties is not easy, and beyond the amount that must be raised without leverage it will be difficult for you to provide favorable return profile for your investors.
