As a seller would you question this and renegotiate a lower percentage of purchase price (3% to listing firm only), or request it is a more even split?

As a teenager, I managed properties that I owned a percentage of.

Of class B (management) share, a percentage is given to the "capital raise" LLC.

I've started presenting offers to sellers showing them the net of the offer minus credits/concessions so they can see the full picture, and not just focus on a percentage point.

I will state that refi appraisals are more conservative than purchase appraisal and not by a few percentage. 

I chose those locations because of cost and cashflow percentages from the BiggerPockets map on where to buy. 

Per case law the courts have not decided on a specific formula or what percentage of CPI.

Auction buying (real auctions, not sales disguised to look like it’s in auction mode) can be successful for investors who invest in multiple auctioned properties over time so that each property represents a small percentage of the overall portfolio of properties purchased at different auctions.  

The math looks like this:$150,000 (ARV) x .70 (ARV percentage) = $105,000$105,000 – $20,000 (ERC) = $85,000 (buying price)This formula is commonly used by house-flipping investors to decide how much to pay on a fix and flip.70% Rule: Formula and ExampleThe formula itself is rather simple: Once the ARV and ERC are calculated, you then plug in the numbers.Take a house that has an ARV of $100,000 and needs $20,000 in rehab.

Then the Disney area may be a good fit.But if you watched some youtube channel with someone, who seems to get a deceitfully large percentage of their info from selling courses, preaching the dream of massive upfront cashflow that you can then leverage into another down payment next year and so on while exponentially increasing your wealth so you can quit your job and live on the beach in Aruba, Disney is the wrong market for you unless you're willing to invest substantially into super tippy top end theming.The good news if you're in the former camp is that prices have come down quite a bit here compared to most of the country with all of the saturation/competion.
