Agree with the numerous other posters who said to stick with WBs for a resale prospect. You’ll sit on a QH or draft cross for awhile… A TB that looks the part for less time, but it better have a dang good video to back up some pretty pictures.
I think you can definitely find something nice for that money. I’m looking for something different (adult jumper prospect), but with a bit less of a budget and wanting something slightly more started, and I’m frankly surprised by how much is out there. This is, of course, assuming you’re willing to buy off video or put together a trip to go see horses all over the place.
Recommend starting with Facebook - your local “Sporthorses for Sale”, “Warmbloods for Sale”, “Hunter/Jumpers for Sale.” The group “Just Hunters, Jumpers and Equitation Horses For Sale” is MASSIVE and has horses from all over the US and Canada. If you’re serious, you’ll honestly have to check it 2-3 times a day to keep up with the volume of horses being added - blink and you’ll miss.
For Canada, I’ve been looking in “Ontario Show Horses for Sale”, “B.C. Sporthorses for Sale” and “Horses for sale - English disciplines - Western Canada”. I’m sure there are more. The Canadian dollar is really appealing as others mentioned, even when you add in shipping. I’ve seen a lot of really impressive youngsters. A lot of the Facebook ads will lead you to breeder websites, which is helpful.
Lastly, try Warmblood-sales.com. I’ve found a lot of breeders posting their 3-5 year olds there.
Good luck and have fun!
