2) Home resort: All resorts have there pros and cons. You need to understand what you value in a resort, what kind of room you'll most likely stay in, and whether that resort is easy to book at the 7mo mark. I was really leaning towards AKV first, but then realized it was relatively easy to get at 7mo, so I went with a different resort that I was happy staying in
2. Home resort
General rule of thumb is buy where you want to stay. That being said, not every resort needs home resort priority to be able to book there. The 3 most frequently available resorts are Saratoga Springs, Old Key West and Animal Kingdom Lodge at 7 months.
That's not to say that having home resort priority there is not useful. For example Old Key West owners will typically book a room category called Near Hospitality House which is a little bit harder to get without owning there during popular travel times. Animal Kingdom Lodge has the only concierge level rooms in all of
DVC albeit there are extremely few of them available. But if you're not picky about these specific room types, you'd likely be better off owning somewhere else.
Certain resorts are less available during specific times. I saw you have an interest in Copper Creek. Copper Creek studios are notoriously difficult to book during early December because it's decked out for the holidays and are difficult to book without the 11 month window. Another example would be trying to book theme park view rooms at Bay Lake Tower during New Years Eve or July 4th where you may not always need home resort priority but at certain times you will.
Some resorts are simply tiny and don't have that much inventory such as Grand Californian or Beach Club and again are extremely difficult to book without owning there.
I'd take a look at the availability charts to get an idea of how difficult it is to book things at the 7 month window and help you determine if you REALLY need to own there to book at your desired room type and resort.

Dues
Your home resort will also determine how much you pay in dues per point. Many uneducated buyers will purchase a resort like Vero Beach because they see that the buy in price is extremely cheap; however, the dues at that resort are the highest in the DVC system and quickly negates any savings that were had from buying Vero Beach instead of a resort like Saratoga Springs.
