I am curious and will be subbing/checking back to answers. I have some questions:
What kind of insurance would you be buying (or would a person buy, if they were to have others riding on their property, and potentially expensive horses living there)?
What kind of heavy and/or expensive equipment will you be needing? Ie tractors, lawn mowers, tillers, utility ATV (like a Gator), pickup trucks, and the like.
Do you plan to start small and add on, or build a business plan and secure a loan/line of credit?
If you purchase raw land, will you be constructing outbuildings, putting up fencing, running water lines, electricity, etc by yourself, with a contractor, as your own contractor with hired help, etc?
If you purchase pre-existing property, do you have in mind what kind of amenities you would like to have? For example, water to each stall individually vs a hose outside, individual runs attached to each stall vs closed stalls with separate pastures, wash rack, tack room, arena/s, dry lot and/or area to quarantine new horses or sick horses, etc etc
Will you be looking for land to grow your own hay, or will you be purchasing from outside source? If you are growing your own, do you have the necessary equipment to harvest and bale it, or will you need to hire someone?
Will you have a place to ride and train, or will you have to ride in the pasture or trailer somewhere?
Do you have a trailer?
Some things that come to mind :) Certainly not everything to consider, but some important things, I think.
I have said what I have said. I have not said what I have not said.
