I disagree with this as a rule.
Definitely might be accurate for some people, but not everyone.
When you have a client with a big budget, it’s much easier to find what you want.
I work 10x harder for my clients with low budgets because I still want to have high client satisfaction and bring in high quality horses to my barn that jump well.
I actually charge higher commission for cheaper horses for this exact reason.
Finding a ch/ad jumper for 80k is easy peasy, people give you the red carpet treatment and are extremely flexible about payment plans. And clients who have 80k in cash tend to be more understanding that the horse may only last them 2-3 years if they are planning to consistently move up in height and will have significantly less resale value.
People who have scraped everything they have together for a 20k horse more often expect the horse to last them forever, and if it doesn’t sometimes even think the horse should have higher resale value if they do want to sell in the future. Therefore if you’re trying to find them something that will suit their usually equally ambitious goals as the person with 80k, you have to really know the rider and really filter through a LOT of horses with quirks or different issues to find the one with the right quirks for that person. And not to mention that they have vetting limitations.
For example my clients bought 3 horses doing the 1.0m jumpers, one was 75k, one 20k, and one 25.
The 75 k horse took me 1 day to put together a list of 9 horses to try that all have records up to the 1.35s, all horses were extremely fun and easy for the client to pick from and and just had to choose the one with the personality he liked the most. Horse was 10, placed top 3 in FEI 1.35s many times, top 3 in 1.0ms almost every class with a bad riding junior in US for a year. Perfect vetting. Is EXTREMELY easy to ride.
25k horse is 13, super green for her age, very hot for kid, jumped 1.0m at local shows but has no USEF to prove it, 3 of the horses we tried were WAY too strong, one we tried to buy had way too bad of x rays, like severe arthritis in both front feet and was extremely difficult to tack up and handle. Took me 3 weeks to create a list to go try. And when I start making a list it’s something I work at like every single free moment of the day I have. Had great PPE.
20k horse, took 3 months, owners did not want to do a PPE, has GREAT usef but is pretty sulky, SUPER spooky (not at jumps, but is super spooky and stuck when alone in the ring) but then also strong once it gets going. I also suspect horse does not have a good PPE as she gets very sore if you over prep her for kid which is difficult considering how spooky and strong she gets.
All of these horses are great warmbloods that are super honest and love to jump and capable of doing the 1.0m division.
But the cheaper ones were harder to find and are older and harder to ride.
