Can a licensed RE agent legally conduct creative financing without getting into trouble?

Plus with real estate you typically use leverage (financing), which significantly reduces your risk and increases your ROI. 

I am in Finance and know how work with number.

I finished my MBA in finance, which included accounting courses, so I thought I know enough about accounting, especially depreciation,1031's, taxation that I can handle doing accounting and filing taxes myself.At the time, I've been advised that I should have good CPA's and tax advisors if I'm engaged in so many businesses.

I am in the process of financing my second investment home. 

If you have enough equity in one of your houses, you can use  HELOC to pull the funds for your next purchase using a DSCR loan.You can look for a seller finance/sub-to or rent-to-own opportunity.If you don’t mind moving and one of you have some of your VA entitlement left, you can purchase the multifamily that way.

If you know any lenders that go low as 30k or creative financing for the deal I'd love to hear it!

Make a solid plan of what you are trying to achieve, that you both agree on, and save like crazy so you have the finances to make it happen.

However, innovative strategies like seller financing or allowing a mortgage assumption could potentially offset this loss.

I'm looking for some resources where I can learn how to properly analyze deals, especially larger and more complicated deals with multiple sources of financing, multiple tiers of investors, rental income to consider, vacancy rates, etc.
