For grins, I went back to look at what MouseSavers thinks was the "going rate" for point rentals. The earliest snapshot of the discussion in the Wayback Machine is
August of 2012. At that time MouseSavers quoted $11pp. Today,
that same page suggests the rate is $23. That is probably not right, but let's assume they were wrong by a proportional amount in 2012.
US inflation during that time suggests that s
omething that was $11 in 2012 should be about $15.56 today. So, it looks like rental rates have risen
faster than inflation---even if you assume the going rate today s $20. This is not particularly surprising. Dues have also risen slightly faster than inflation, as have rack rental rates. Throw in the huge volume of advertising that a few of the larger brokers have done over the past ten years+ to get the word out on
DVC rentals as an option for the infrequent guest, and Bob's Your Uncle.
Whether Iger or Chapek is up to the reader to determine.
As a point of reference we rented right at 11 months in 2021 for a 2022 trip (last rental before buying). We paid $18 per point then through a website that had cancellation coverage in their policy (if the owner cancelled our booking that is). Not sure if I can say who it is because they aren't a sponsor. If I recall correctly, they adjust the price shortly after we booked to be $19 per point.
This particular rental cost us just over $1,700, which the cash rate was $528.86 per night at that time (without discount).
Look at that same website, the current price per point for an 11-month booking is $23 per point.
If I use the CPI Inflation calculator, $18 in 2021 has the same buying power as $21.72 today (actually, Sept 2025 as that is the most recent data available). So rental rates, at least through this website, have gone up faster than inflation. Inflation has gone up 20.6% in that time period. While the rental rate has gone up 27.8%. The $19 updated rate would represent a 21% increase and aligns almost exactly with inflation. Rental rates appear to be increasing, on average, a little more than 5% per year over this time period.
We first rented in 2013 for $13 per point, again through the same place. $13 in 2013 has the same buying power as $18.16 today. So again, rental rates have exceed inflation. Inflation has gone up 39.7% and rental rates increased 76.9%, approaching double what inflation has done. Rental rates appear to be increasing, on average, a little less than 5% per year over this time period.
This particular rental cost us just over $1,100, while the cash rate was roughly $1,850 at that time.
So it seems, on average, over a long enough time period, rental rates go up roughly 5% annually, give or take. At least through this particular website, for an 11-month booking at a WDW Resort.
If I look at the cash rate for the same trip in 2026 (from 2022), the current cash rate (booking in 2025 for 2026) at the resort we stayed at is $624.75 per night for that same time window (again, ignoring discounts) compared to the $528.86 per night in 2022 (booking in 2021). That is an 18% increase over that time period, a little under 4.75% per year. Slightly less than inflation, but not too far off either, and prices do fluctuate, so these are just snapshots in time.
EDIT: So it seems dues increases are increasing a little faster than cash rates or rental rates.
