Don’t forget the extra liability of boarders, their friends, all of the vet, farrier, and supplier visits and deliveries. Where will you store hay and feed? Who will do mucking, turn out, blanketing, wound care, feeding, and monitoring turn out herds? Don’t forget the people who come with the boarders either, the relatives, the friends, the people who are letting their friends ride, and the people who will trespass just to see the horses. If you have barn hours, there will always be people who feel free to alter that, and the people who will drop in to your home. Parking, road maintenance, and will people be allowed to park their trailers there?
Honestly, someone’s idea of covered storage for RVs, boats, trailers, etc, with 24/7 access sounds a lot better. I know someone who has a huge storage unit facility, and she found the most profitable part is when they built the enclosed (except for the long side) high roofed storage for RV’s, trailers, boats, classic cars, car collectors, etc. The best factor for her is that there are a few plexiglass skylights on each row of storage, so they have no electric outlets in the storage (you have to watch for people who will live in their RV in the storage section), that really reduces fire hazard, and their insurance for the facility. The main gate has a card you wave (RFID I guess), so you can enter at any time. There are individual gates across each stall, and the tenant either supplies their own, or they get one (the locks are about $5.00 each, and cheaper in quantity) from the facility to keep. If a tenant loses the entrance card, they pay a nominal fee for another one, and the previous card is disabled. If the tenant loses the key to their padlock, they have to get a lock smith, on their own dime. My friend said there are people who have so many RVs, etc. that they rent an entire row of units, and that’s a very good income with minimal work, and with a credit card required for autopay, easy for the storage area owners.
