It sounds fishy to me that this guy is that experienced and cant figure out how to get long term financing on BRRRs.

I was more on the lines of trading bitcoin for properties and funding rehabs with bitcoin and or bitcoin or crypto currency replacing cash all together.

Also, each side of major roads like i35 and 377 will generally have very different prices.It happens a good amount in smaller towns and especially with CRE where you really can't run a sound comp because there's just no data to do so.

Use threaded nipples for shutoffs so they can easily be replaced down the road.Use hard waterproof surfaces whenever possible.  

We have a goal of replacing my wife’s income in the next couple of years and replacing my income in the next ten years.
