Look at all the resales currently listed and compare the number of points, their location, the use year, and any banked / borrowed points. This will give you a 'feel' of what the average 'asking' prices are. Then check with the broker you're working with and see what recent actual 'sale prices' have been. That would tell you what is a realistic bid.
As you know, the biggest factor to calculate is the bank/borrow equation. Also, who is going to pay the closing costs.
Generally pluses would include: A lower asking price, a more difficult resort (EG BWV), banked points, seller pays closing costs.
Negatives would be: high asking prices, borrowed points, borrower pays closing costs (this is most common).
Finally consider use year. Are current year points used or available. If the UY is for example September, then that contract is still in it's 2000 use year, and all 2001 points become available in a couple of months. If a contract has a June UY, then it's already into it's 2001 year. This could also make a difference in how many points you would have available at the time of year you would like to travel (I.E., when do points renew each year)
