There is far more variation in state LLC laws when compared to corporation or partnership laws of any given state.

You might also look at Homelight.com and Upnest.com, which are pursuing variations on what you've described.Most of the real estate industry is at least 10 years behind corporate/B2B sales in terms of using technology for lead gen and funnel management, and even if there's interesting stuff already out there from Zillow, etc., you should take that as a sign that there's already a market, and given the overall size of the opportunity, there's plenty of room for others to play. 

(any niche almost) find a rockstar internet marketer able to see what people type in Google then rank mega sites with all variations of search phrases + all cities within X miles and show up for 20,000 first page results...that'll dominate. 

There isn't a standard, but the majority of fees in Florida are 6%. 3% to the listing agent, 3% to the selling agent, or some variation of that.

Or some variation of that. 

As with the rest of Memphis, street by street and block by block, there can be significant differences, and out of town investors can get burned.East Memphis is mostly slightly newer homes than midtown, and mostly more stable than midtown - not quite the same variation in home condition.

I have seen more variation in the re-up than in the percentage model, which is virtually universal. 

Ok, that out of the way, my closing argument is I have done countless wholesales of more variations than I can recall and I am a-ok fine, I know many many others who are just the same and even a few who have hundreds and thousands of wholesales under their belt, all in MN, all without any problem other than the occasional person banging the "you can't do that" gong, well, their wrong. 

My wife and I just finished working on a variation of one that either Brandon or Josh had posted a while back.

As mentioned, some with have variations on that name or may have come up with a bit of a trade name for the same thing.
