For this I plan on charging 10%  of rental income as management fees to LLC-A.Some of the benefits of this vertical integration brought by LLC-B is: (a) Ability to contribute to retirement plans (solo 401K, etc)(b) home office deduction(c) health insurance plan premium, among others. 

I have done it with some contractors taking Paypal where you can use a credit card on that site with a fee, or QuickBooks is another one too.

A fee well spent for some types of investors.

@Christopher Alley we use a lot of private money in the rehab business, and I have never paid any up front fees. 

PM's will keep all late fees, they hold the security deposits so they collect all the interest on security deposits. 

Tax free appreciation and rents significantly trump the loss of depreciation and custodial fees.

I think my fees are high until I shop around and then I am thankful. 

We successfully set up the co-hosting on Airbnb where I receive the agreed upon 18% + the cleaning fee.

A common misconception is that real estate properties under $1M have a smaller tax basis and therefore do not benefit from a cost segregation study due to the associated fees.

We got lucky the county picked up the waste dump pickup and dump fees.
