Since even though in mo CA is going to take a cut since you're a resident.

Have done lots of reading of online material, books, etc. and simply need some human contact. 

Cutting corners or under-estimating expenses on a crappy investment just to make it look good still results in a crappy investment... you just end up paying more for it.Now, on to your personal calculations - I see one error (and it's a small error that leads to large differences).

Not just because it’s only been 4 months, but because at a loan to value ratio of 75-80% on refinance, you simply don’t have enough equity yet.

I got a query from a new company called REX, a startup that says it only charges a 2 percent total commission fee because it cuts out the middle man by using artificial intelligence and other high tech to identify and market to the type of buyers interested in my property.

Hi @Fred SenaYou won't get a cut and dry answer to this question, but hopefully my response can provide you some insight as to why.

I think it's much easier to think of simply spending all the proceeds since if you buy multiples as Clayton said you may want to allocate your proceeds so that a few properties you buy for cash or with minimal leverage. 

In regards to your next flip, I bet you will have no issues cutting the flip time in half now that you've worked out the kinks in your planning, timing, budgeting, etc.

An S-corp is generally not advised as a type of entity for holding title to properties but does have some benefits especially if you are going to be employed since it can cut down on self-employment taxes. 

It's not simply the difference between the sale price and the purchase price.
