Yes, you can rent these directly from Disney for cash instead of "renting points" from a member. However, members own the majority of the units at BLT and DVC only owns a small portion of the units, about 3% of the units. Your travel agent was pretty much correct about not being able to book these until at least 11 months out. Members have the first opportunity to book these (owners at BLT book from seven to eleven months out - no other DVC owners can book these until seven months out). However, if a member turns over their points to DVC to book a non-DVC Disney Collection vacation, like a Disney hotel or
DCL or ABD, DVC will turn the equivalent units over to Disney Reservation Center (sometimes still referred to as CRO - Central Reservations Office) to sell to pay for the member's trip. You'll probably pay more by booking directly through Disney than you might by booking with a member or a broker who pairs someone wanting to rent a DVC reservation with a member who has a reservation to rent out (known as renting points). BLT can be hard to get from a broker at more than seven months out (not always impossible, just a bit harder) because a lot of BLT owners might not be turning their points over for renting. Lakeview two bedroom villas will probably be easier to book than a theme park view or a standard view.
October is a really popular time for DVC members to go to WDW because of the Halloween parties and Food & Wine Festival.
You can check out the villa layouts at the DVC member site by clicking on Find Destinations and then Bay Lake Tower.

Start checking the DRC site about 11 months out to see if you can find anything available for cash. Or start looking at brokers or individual members (read the guidance about renting points on the DVC Boards Rent/Trade Board before you make a deal with an individual - there have been a few scams, but just a few).
