Doing diligent screening is going to be the line between success and failure of your business.  

They don't invest in their business enough.undercapitalization is the #1 reason for business failure, wholesaling is no different.

Imagine, you're meeting with a sheetrock contractor on site and he says it's gonna cost x for the job, and you whistle and exhale and sigh and then say...well that seems like you'll be charging me y per installed board and I know the /board installation rate is closer to z and I have estimated abc number of boards... well it adds a level of professionalism and confidence that can sometimes make the difference between success and failure. 

All roofs have pros and cons and we could definitely debate it all day and all be correct but where EPDM roofs have failure is from shrinkage, seam pops, and puncture resistance.

Read the book, walk through a property, generate a SOW, use his cost estimates and then add 10% ;)  Stop trying to cut corners - failure to educate yourself is a quick ticket to losing money hand over fist.

If you consistently make the wrong decisions in your life and have a history of failure, then I would quit right now!

Different job, same boss.Sorry, verbal instruction is a failure.

I'll offer the advice I received from a very savvy RE attorney, one who has seen both successes and failures:  "Don't try to squeeze the last dollar out of a deal." 

There's also no condo association to fine the other unit's owner for excessive noise, failure to keep the exterior and yard well maintained, parking a dozen junk cars in the yard, etc.I *hate* the location.  

For example, failure to advise the transacting parties about paying realty transfer taxes can have serious consequences for lawyers.
