You want to look for the lowest maintenance fees with the largest point total.
For example, you can buy 122,0000 points a year at the Grandview in Las Vegas with an annual maintenance fee of $835 plus your RCI membership.
Or you can buy 98,0000 points a year at the Grandview for the same annual maintenance fees of $835 plus your RCI membership.
The difference is that the 122K point contracts can sell for $2,000 or so and the $98K contracts are usually given away.
You can look on ebay to get a feel for what costs are included or are not, depending on the listing. Closing costs and resort transfer fees are sometimes included and sometimes not. Some will have all their points available and some won't.
As you can see, there are many factors at play.
