But I'm throwing them out there to demonstrate the reasons why its not as cut and dried as some people think.They may assume that a house that is negative cash flow has to be sold no matter what even if you have to come out of pocket 20k or 30k to do it. 

Real Estate Express for the courses, prep agent for the exam.Granted I've been around this a long time before even thinking about getting licensed, but I had a opening come up last second for the exam and did a cram with prep agent podcasts and was able to pass the exam following day.Prep agent makes dry material at least engaging....and easy to digest in chunks 

I did the online course (real estate U) because I have a young kid but it was super dry and boring, though it got the job done quickly and cheaply.  

This is the time to have dry powder anyway, and I see this all as the same bucket, since it's all cash and cash is fungible.

Look for any moist on the soil as well as disturbed soil which will show that either equipment or tools were placed in that area. 

Was this a dry cleaner before.  

Keep some powder dry to take advantage of deals when the market turns and to double down on the sponsors that perform on your initial investments.

If so what kind and why didn't they develop the land.When looking at land, knowing things like, soil conditions and other subsurface factors are huge for developers. 

They are fanatical about the test because water leaking into the soil under the house is devastating for a slab foundation.

So, its still going to be the same dry material.
