Im considering a seller financed deal on some properties where I have significant gain.

You will gain tons from it.

Plus, if you live in it for 2 years and fix it up, you can sell it capital gains free if you want (live-in flip).

Because if less than a year, I really doubt you will gain much appreciation.Don't forget closing cost!

After I’ve gained enough capitol I’ll start BRRRRing and flipping some of the deals myself.

This allows the REI to exponentially grow as opposed to  the limited linear growth that current strategies allow for.This also allows for paying higher interest (using special rules) and even more than the Asking Price for a property and make instantly more money, more cash, and more future gains (appreciation and equity) then using the current buy low and sell high system. 

Saved a ton of money and made some good capital gains after 8 years!

And meanwhile, I'm gaining equity in principal paydown and longterm appreciation.Your wildcard is your VA loan.

If you are wanting some consistent monthly income and want to avoid capital gains or bumping your income into a different tax bracket, then continue to owner finance them.

@Ashish AcharyaBut “flip income” is capital gains, isn’t it?
