There has to be something in the middle, right?

I'm in middle TN but have properties in TN, NC, and under contract in AR.

My name is Jens Hansen and I’m a newly licensed REALTOR® with Compass here in Danville, CA (a family-friendly suburb about 30 miles east of San Francisco).

Next, I was hoping to receive clarification that my understanding of wholesaling is correct.1) Find a motivated seller and agree to a selling price (preferably below market value) e.g 100,000 (where avg price in location is 150k)2) Find a buyer and propose a price e.g 120,0003) Take finders fee/assignment fee of £20,000 as profitIf this is so here are my questions:1) What is to stop the buyer/seller agreeing to a separate price cutting out the middle man?

I'm in the Middle TN area reach out if you have questions. 

It is located right in the middle of a free trade zone.Again, I don't actively invest in SFR or commercial in the city, but I do love Texas for investments and specifically for the way they handle taxes and what those taxes are used for. 

We purchased a property on the east side for $90k about 2 months ago on market.

The Median Rent is the rent in the middle where 50% of area rents are Higher and 50% are lower. 

Many landlords group 2–4 properties per LLC as a middle ground—especially if they’re lower-risk, like SFH in good neighborhoods.

Some even keep a reliable handyman or plumber on call so if a leak or similar issue comes up, they don’t have to scramble in the middle of the night.
