Tax benefits is just a by-product.

If someone is going to do it full time like that it only makes sense to get your license.But for the part-time investor buying their second or third property, it doesn't make sense, and that's where you come in and can be of extreme benefit to them.

In a commission only job, you want to benefit from the work that you have put in. 

that works you could do a basic LLC and have uneven distributions which is the major benefit to the LLC.. the LLC lends the money you have 2 or 3 buddies as members.. you the sponsor be the managing member.. then cut the pie however you like.. when I had my shops I did this through guidance lines with my banks.. we put the cash out for the loan.. then back filled and pulled from our guidance line.. for every 1 mil in cash we had we got 4 mil from the bank..

Confidently explain what the benefits are.You can not wholesale every house, simply because sometimes it is not the best thing to do.

That 30 day window is a great benefit. 

You trying to pay more upfront is smart from your perspective (maybe not in terms of the benefits of having tenants pay down your loan, but definitely in terms of minimizing interest payments) but the bank doesn't see it the same way. 

I'm going for COCR and everything else is just a benefit.

The tax benefits from doing this should help reduce or even eliminate capital gains and depreciation recapture upon sale, but again you need competent advisors to set everything up to get the optimal benefits from this strategy. 

@Percy YarlequeWhat you are considering is not possible within the IRS rules.You are a disqualified party to your IRA, and may not transact with or create any kind of direct/indirect benefit between you and the IRA.
