Do horse racing partnerships have ongoing expenses or fees?

Do horse racing partnerships have ongoing expenses or fees?  Sometimes.  It depends on how the partnership is structured.  Some will charge your a monthly fee to cover ongoing expenses.  If they do, this may be a fixed amount based on average estimated expenses, or it may vary depending on exactly what they spend on the horse each month.  The latter is the riskiest type to participate, since there may be unanticipated expenses if the horse has medical problems.  There are also partnerships that don't charge anything on an ongoing basis, but instead bake the expenses into a mark-up on the cost of entering the partnership.  I would consider these the safest, since you know exactly what you'll spend when you make the commitment to join the partnership.  Some stables offer only one of these structures, while others will give you a choice of how to handle ongoing expenses.
