I love this strategy, it makes so much sense for Rookie Investors trying to scale.

You are right that it's easy to make a $10K mistake as a rookie.

Texas law provides significant protections for homestead properties against most creditors, such as credit card lenders or lawsuit judgments, such that your falling behind on payments will not cause you to lose your home.

I literally get a Christmas card from my Plumber - which tells me we are one of their bigger customers. 

If you do, I think you will see what I see from afar.Another comment above stated that you should check how much under management/ownership the sponsor has any anything sub $500k = rookie.

We heard of guests who checked out at the end of their stay and decided to notify their credit card company they did not book the reservation.

I recently heard an episode on the rookie podcast about a couple that does rent to own.  

I'd love some input on what to do:I am a 40 yrs with a stock market investments of 350K trying to coast fire in the next couple of years.I just got a green card and moving to the US from Canada and looking at which accounts to invest that money in the US.But I am not sure I will stay in the US in 10 or 20 yrs.What do you think would be the best strategy to coast fire when you are not sure where you are going to be in your later years?

Broke student had no money before the course, but now has a $5K - $10K credit card balance now after paying for high priced wholesaling and get rich quick education.- Obviously, student is not going to be buying a house anytime soon, much less making cash offers.

You can get cash from your credit cards.
