The average income of a racehorse owner is difficult to figure. Not every race horse owner is extravagantly wealthy, but it helps to have a lot of extra cash to burn. The annual cost of keeping a competitive race horse, according to Forbes, is about $60,000. For quick comparision, that's equivalent to a year of tuition, housing and books at an Ivy League college.
Hannum said the demographics of horse owners changed during the last 20 years.
"They have some disposable income," Hannum said. "They're professional people who, instead of buying a boat, buy a racehorse."
"It's people that have this gene. They fall in love with horses. That goes from hotwalker to farrier (blacksmith) to the owner," DeBunda said. "They do it because they enjoy it. They hope to break even or make a little money. Owning a horse is like owning your own sports franchise you get to pick your own players and your own coaches. But when your horse wins, you're the only one there in the winner's circle."
