Also, point rental companies don't necessarily work first come first serve - its vaguely first come first serve, and your chances are certainly better with an early request. When I rented by BWV points, I wasn't looking for the first reservation the broker sent me I could make. I was looking for a reservation that met my needs (i.e. the number of points I wanted to rent in a single reservation and one that I could make when I had time to make it - which due to life, turned out not to be the first week I told the broker I had points available. I also didn't want to make a reservation during the last quarter of the year - when a lot of members travel, and I didn't want to bother with a high demand room type, that might be gone when I logged in - I wanted one and done on my own terms). I passed on a dozen reservations because they didn't fit into what I wanted - the renter was looking at the wrong time of year, or didn't want to use the entire allotment I wanted to rent, wanted a BWV standard view, or I was contacted to rent when my project at work had blown up and I didn't have the capacity to think about making
DVC reservations. At that point in time, for the resort I was renting, I was getting three or four offers a day from the broker - so I could afford to be picky.
As Kat and Craig pointed out, VDH just opened, there won't be that many owners looking to rent their points as most owners who buy want to use their own points - they aren't buying to be in the business of renting. I'd make other plans - cancellable in case something does come through.
EDITED: Also, if this is stressful, it isn't worth the bother. Because renting points through a private owner DOES carry risk, and that risk, for some people, creates a level of stress that isn't worth the savings. Vacations should be enjoyable, and while planning them isn't always and there is always some level or risk and stress, there are ways to keep stress in check - renting points instead of booking a cash reservation isn't one of them.
