If you're reviewing prior ROFR thread data (which I highly recommend to get a sense for the sorts of deals that are possible), I typically take the price/point multiply it by the number of points on the contract and then see what the difference is between that amount and the total amount paid. Usually, the total amount paid is more because the buyer will be paying the closing costs (about $600-$1,000) and current year dues (dues cost x number of points in current UY). Starting with 2026, there is also the $500 CAF, but that won't be part of older ROFR data. At least one broker (maybe more) charge the buyer an administrative fee ($240 for the one broker of which I'm aware).
Of course, this means that the price/point is not the only possible point of negotiation and is not necessarily reflective of how good the deal was. A deal at full list price (say $140/point) where the seller is covering current year dues (assume full current year points), closing costs, and CAF is FAR better deal than $130/point where the buyer pays all those items.
If a contract has full current year points, but you get the seller to pay for those (typically thought of as buyer will not reimburse seller), and the dues are $9/point, you effectively took $9/point off the purchase prices. If a contract has 100 points, and you get the seller to cover the CAF, that's $5 off per point.
Some brokers/sellers are more willing to negotiate on some of the items than others.
