I have tried many other things, but those tried and true methods will make the phone ring. 

I am learning about this method right now using David Greene's book.

Real estate investment has long been a trusted and proven method of earning a limitless opportunity.

I like that it is pretty simple but has flexibility because it has the affect of financing rates. 

Haha I was thinking about it and one way that came to mind besides getting a partner which is also a good idea, is to consider finding people who have no debt on their homes and using the seller financing method to secure a deal.

Houston is great for using the BRRRR method. 

When using the BRRR method how do you avoid putting so much down?

We have had a hot rental market in Colorado for a decade now so we have the flexibility to raise rents every year but like @Nathan G. said, we save the larger increases for turnovers and smaller increases for renewals.

If there are multiple listings in that area without permits, then there is a higher likelihood of there being no formal permit process.That is so not a reliable method.

Would I be able buy this property subject-to legally using this method?
