At a blackjack table, the house generally has a couple percent advantage over the player who is using a reasonable fixed strategy. 

Stick to Black Jack. 

I usually stick to blackjack, roulette and slots.

Compare the difference between getting a 300-unit apartment building for 80-100 million dollars in Detroit vs Florida (or any other state.) and getting negative cashflow.There's this concept called "EV" in blackjack card counting.

Congrats on the profits but it’s like patting someone on the back who just won at the Black Jack table if you’re strictly depending on appreciation .

If the funds are coming from somewhere else, it's a financed transaction, pure and simple.The reason for this is that if the funds are yours, there's 100% chance the deal will close (if you want it to); if the funds are not yours, there's less than 100% chance the deal can close (your lender can die, go out of business, decide he hates your guts, lose his money at the blackjack table, etc).

They think any deal will be that "easy" and then go broke on the 2nd one.Kind of like winning your first few hands at Blackjack and then doubling your bets and losing it all on the next few.Keep up the good work but be careful.

It can happen, but it is, literally, equivalent to sitting down at a blackjack table and winning hand after hand.

I took a realtor course through Century 21 a few years ago for fun (i was making good money as a blackjack dealer) So I am starting at a point where I know the basics.

This isn't black jack where the rules always statistically work.
