I wanted it as a BRRRR but ended up letting it go as a wholesale deal when another investor approached me and offered a $6,000 assignment.

Will definitely add those points to the way I approach my future real estate investments. 

But, sure you can/could try to use this a negotation approach. 

How would you approach a situation like this?

I am currently single and have no kids so I like the approach of finding SFH's with 4+ bedrooms (the more rooms the better).

If you approached an owner about a sale you might ask if they want to owner finance.

And take several approaches including internet, social media, telemarketing and mail.

. - sometimes almost comical, if it would not be so serious.A great inspector is professionally trained in this field (not as a contractors), uses software and has a systematic approach to evaluate a home, identifies all problems correctly, but can also explain the real world consequences and not refer for everything to "further evaluation by a qualified contractor".

So, $100k ARV average on recently sold homes in the area, I would approach the sellers with a MAO of $20k in mind for the lot. and work your way down from there.

This is definitely an aggressive approach and I appreciate your input.
