My current flip is under contract and appraised at $239,900.

Once I get one property under my belt, I plan to scale up next year and purchase at least 5 multi-unit properties by the end of 2019. 

Do I need a separate EIN for each LLC or do they all fall under one?

Just look under the ownership section!

AdditIonally, I already assumed we’d have to have a very thorough tenant screening process but I dIdnt want It to be to the point where we couldnt get anyone under lease.

@Frank Cruz I haven't done any flips yet, but I classify my rental portfolio under an LLC.

Some lenders, (Like me) will open with total debt bid unless I'm under water and/or I don't want to take back the property for reasons I don't want bidders to know about (Like the foundation is falling into a crevice) so, i'll open at less than market value to entice someone else to bid.

I watch people buy homes 50k under asking price but I have made similar offers and seem to strike out 1 after another.

"In the case of any investment held by the tax payer for at least 10 years and with respect to which the taxpayer makes an election under this clause, the basis of such property shall be equal to the market value of such investment on the date that investment is sold or exchanged. " If anybody has questions specific to opportunity funds DM me.

Its the staple of any estate planning transferring property out of your own personal name and into your trust, then you just add the layers of the LLC and Asset Management Companies depending how many properties and how many layers / degrees of separation you want.
