What you cannot do is use the funds that the C Buyer brings to escrow and pass those funds through escrow and use those funds to pay off the A Seller. 

If you're not careful you can easily end up paying $200/mo in subscriptions without even realizing it (this has been the case with my partner and I, between video game stuff and music and entertainment, etc. etc...).

I dont think you need advice for anyone how to structure this your already experienced operator.. the decisions is do you want to keep adding doors or concentrate on paying off what you have.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

You have to read a set pf plans to answer the questions, etc....And if/when you pass, you'll have at least 5 years of paying dues and losing money before you're any good.

If the properties are split into an LLC, then each LLC will need its own accounts.Checking: collect all income here, then use it to pay bills.

Many of these platforms also send the same leads to multiple agents.Since most of these paid leads require work/follow-up anyway, have you thought about paying less $ for leads where there is significantly less competition?

Any jobs with a base pay + commission? 

I am looking for one that:- provides checkbooks, and - pays a decent interest rate.

No one wants to turn in pay stubs, taxes, etc. if they can avoid it.
