There is no such list, because the point 'cost' varies by not only just unit size, but by season and by how long it is before check-in. Hypothetically, say a 2 bedroom middle-of-the-line unit in Summer season might have a 'value' of 60,000 RCI Points if booked a year before move-in. That same reservation might 'cost' 40,000 RCI Points to book in May or September, or 25,000 RCI Points in the off season. And if it's still vacant 45 days before move-in, it might be either 7,500 points or even a 'last call' for under $300 cash for the week.
Since you have to buy into an RCI Points resort to acquire the points, if you buy the size and quality of resort you expect to use for your family, when you exchange the points you get for a different, but more-or-less equal property, it should be an equivalent 'cost', plus the exchange fee that EVERY Points exchange costs (currently near $300).
In other words, don't expect to buy a 1 BR unit in 'mud season' at 'Podunk Arms' resort and trade it into a 2 bedroom Disney property in high season. It won't happen. However, you might own a higher end resort property in High season and get multiple exchanges from it if you want to- or save up 'extra' Points to use later. You can also 'borrow' from upcoming years points at your home resort as long as the annual MF is paid ahead.
Hope this clarifies it some.
