My gut feeling is the money is/was at the horse farm--keeping this location secret would be extremely important to several parties in a variety of scenarios--whether Taylor disappeared on purpose or not. Imagine hiding money at a remote location only to find it mapped out on a international website with hints that it's now buried treasure. Not good. I'm not saying Taylor hid it, either--it might have changed hands voluntarily or involuntarily. I'm not saying that anyone close to her knows for sure, either, but many different things could have happened, and perhaps, to be safe, it seems best not to reveal the loction.
