Oil tank is properly decommissioned.

They did an oil tank sweep and there was no tank residue or history, so that was a plus.

I've only recently started listening to bigger pockets podcasts, and reading about real estate. my vision is the same as most people on here, which is multiple passive income streams, one of them being real estate. it doesn't take a genius to figure out austin real estate has a pretty high barrier entry to market, with a lot of big fish.. that being the case, I'm wondering what would be possible ways to enter the market (eg. foreclosures, gentrifying neighborhoods, off market properties, etc.), and potential strategies to look for and assess these deals.

The oils are messy if spilt but the major issue is it will set of smoke detectors.

Still I agree, no reason to cave on this or anything.Vaping leaves the resulting oil behind in which case can develop into what’s called “ popcorn lung”  in a person from it being trapped in their lungs . that residue in the air is sticky and gets all over the place and of coarse the hazards of a potential  fire .

Only thing I would say though is don't focus too early, meaning know whats out there, question a lot of things and  know why you are focusing on say large Multi-family vs oil and minerals.

Teach a man to fish, and all....

However, the drillers hit oil nearby. 

I am currently a full-time engineer with an oil and gas company in Corpus Christi, TX.

Plenty of fish in the sea keep looking till you find the right one.Avoid th ecomplication of having to deal with a co-signer.
