There are a few things to think about here:
1) You can make any offer you want - pay MF, don't pay MF, reduce price per point, etc. They may or may not take it.
2) Since this contract has a lower utility to you than the near term points would indicate, you might consider making a lower offer. By the time you can close, you would be well within 7 months, and you would probably be renting out points at Saratoga Springs during fall frenzy.
3) However, if someone makes an offer that has a plan for the 2018 points, they may make a higher offer than you. Let them have it.
4) Once you decide what the points are worth to you, you can "present" your offer as a) Yes I'll pay MF for 2019, but my offer is $123 (say) a point. or b) I won't pay MF, but I'll offer $130 a point, (say). It really depends on the seller. If they paid $90 a point many years ago, they may be happy to get $123 per point, but they have a recent memory of writing that check for the MF, so they are emotional about that. OR If they paid $200 per point direct to Disney in a recent transaction, they may balk at lowering the price per point, so you offer no MF.
5) They may also be emotional that they had plans to go to Disney in 2019 (hence the borrowing) and it did not work out. So they really don't want to pay the MF.
6) Think about dollars out of pocket - that should be your guide. That would be price per point + 2019 MF + Closing Costs. Also, when you look at it this way, $1 per point in your offer is only a $283 increase in your total outlay. This is a purchase that will serve you for many years, so once you find the contract that meets your needs, don't sweat about a few dollars per point.
7) The broker may be more inclined to like offers with higher price per point and lower MF, since they are compensated on a percentage of the sales price (not the MF). But this is pretty small dollars - maybe $200 out of a $3500 commision.
8) The MF for this contract would be about $1800. This is $6.40 per point, which is also the discount per point you are asking for if you don't pay MF
9) I would assume that the 34 banked points in Oct 2019 were banked from Oct 2018, so they would expire Sept 30, 2020.
10) The lack of points in 2019 would give me pause. You really don't have points to use until Oct 2020. So either you skip going to Disney in 2019 - or you figure what it would cost to stay in a villa at Bay Lake Tower if you rented points - and that is your lost value from the screwed up situation. Another way to look at it - if you are calculating a break-even point, this contract throws the break-even point back a year and a half. Most people when they make a large purchase like this would want to start enjoying it sooner than that. But if you can get it at the right price (Study the ROFR threads), it might be worth it.
11) Let's say I already had points at BLT, but I knew my family was growing through grandchildren, and I saw the need for a GV or 2 2BRs coming, I might be happy to buy points that I can't use for a couple of years, if I can get a good price. But if I am a new owner, I want to enjoy the points sooner than that.
12) The screwed up points situation might make it less likely that Disney would exercise ROFR. So you might get through ROFR with a lower than normal price.
Good luck! and YMMV
