Rentals, through rental agencies, and online through members, are not actually of the points themselves. A “rental of points” is just a euphemism for someone making a room reservation for another using points, and that other pays an amount charged per point used to make the reservation.
So to rent only 25 points through one of the agencies, means you would be paid to make a reservation using those points. And to go through an agency may be difficult because it might require that you have availiable more than 25 points.
25 points do not go far, at most 2 nights in a studio in some resorts for some parts of the year (25 is not enough for two nights in others). Moroever, even if you get someone to rent, that two night reservation is not likely to equal exactly 25 points. You could possibly do an actual reservation and then try to rent it, and agencies do take those, although they may not do it if it is for only one or two nights. Moreover, they need to find someone who wants exactly what you are renting and that can be difficult.
It is possible there could be a rental because sometimes those desiring to rent are only looking for a night or two in a studio, but usually the desired rentals require more nights.
The alternative to the above is an actual transfer of points to another member. An issue with transfers, besides finding someone to transfer to, is finding anyone who wants just 25 points. Both the transferor and transferee are limited to one transfer per use year, and thus anyone who needs more than 25 points is not going to do a transfer for only 25 points, and those who need less, will not take the extra points. Also, though it does not appear DVC has ever stepped in to prevent a transfer for money, there is an actual DVC rule that prohibits anyone from being paid for a transfer. Rental agencies usually do not engage in transfer activity, and you would likely need to use another method, such as finding someone online to do a transfer to.
