The problem is that any boat in the size you are looking for that is within your budget will require upgrades to the rigging
at the very least before heading offshore, and very probably electrical as well. The sails won't be newer and there will likely be less than you would like. Then there is the engine. Most boats in that price/size range will have the original engine. If a diesel it might only need a good going over, but it could be an Atomic 4 that's ready for the trash bin. I would budget a minimum of 10 to 15k for needed upgrades.
