My friends and I have owned, shown, trained, bred and sold horses all of our lives. We do it because we love them and enjoy being around them immensely. The advice I’m going to offer comes from about 40 years of experience with all of the above.
There are only a few ways some of the people I know have been able to make money with horses. Training and brokering (commissions earned from sales can add up to quite a bit if you’re good at it) are two of those. A trainer can take years to get established and a horse broker has to know just about everybody in the biz.
In your situation, IMHO buying a pregnant broodmare and expecting to get your investment back would be the equivalent of walking in the door of a casino and putting your $25K in a slot machine hoping you’re gonna win it all back and MORE…
So your girlfriend wants you to buy the mare (mares are usually bred in Feb or March in the US so they will foal as close to Jan 1 as possible). The mare should be around 4 mths pregnant by now so you would still have 7 mths of gestation left and 4 to 6 mths before the foal is weaned. She’s gonna eat a lot, need regular hoof trims and deworming and none of this is cheap. Costs for vet checks and vaccinations can be added to this, also. How much will the boarding fee be for where she’ll be kept before and after foaling? Foals are usually weaned at 4 to 6 mths of age but they’ll start trying to eat their own share of hay and grain within a few weeks. The foal will also need certain vaccinations starting at six mths. Don’t forget the cost of insurance for the mare and foal. This should include mortality and major medical. For a $25K horse, this would be minimum $1200 a year and I believe I’m really quoting below what it really will be. Also, stallion service fees are not cheap. Who will pay for this plus semen shipping, AI if allowed for the breed, boarding fees if AI is not allowed, vet expenses for AI and pregnancy check? The expense list can go on and on…
If you decide to do this, you should ask for help from a knowledgeable friend to outline all of these costs and who will be responsible for what and for how long. Girlfriend or not, remember this will be a business deal. Get it in writing and have your girlfriend sign it. Make it a legal and binding document. I still seriously recommend you not do it. So many things can go wrong, not just with the horses but between you and your girlfriend.
I, too, question her asking you for any amount of money. Since she is a trainer, she knows what a HUGE gamble it will be. If it’s as easy as she and the mare owner are saying it is, we’d all be rich by now, and she wouldn’t need your money! That’s a red flag for me that she asked you for money that you’ve worked hard to save so soon in your relationship and If you decide not to do it, it will be another red flag if she gets upset with you and also if she gets upset if you want to make it all legal and binding. I still say Don’t Do It…
Sorry so long… Just wanted to give you an idea of what’s involved.
