I have a 9-5 job w/ a half-hour commute and keep the horses at home. I also work 2-3 evenings a night at a second job (and I may or may not stop home for a quick farm check in between jobs.)
I am lucky that I live set quite far back off the road (our semi-private driveway is 3/4 mile). And we are in a dirt-road, rural neighborhood. This gives me some serious peace of mind. I have never had a horse escape but if one did while there was nobody home, I’m pretty sure he would just graze on our lawn (they don’t like to go far from their buddies) or pay a visit to the neighbor’s horses. So keep this in mind when you are looking at property.
My mother and sister are not horsepeople but they are home during the day about half the time so that’s nice too. I have a horsey neighbor that lives next door and is home some of the time too so if something were amiss, she may be able to help out until I could get home. In addition, I have another horse-lady friend who lives about 2 miles down the road and is a stay-at-home mom.
I have actually dabbled with the thought of installing webcams with a view of the paddock and inside the barn, just for fun and extra peace of mind. Never do find the money for the project (which would run me roughly $300-500).
It also helps so much to have a flexible/understanding job/boss. In my office things are fairly laid-back and I know that if there was a problem I would be allowed to drop everything and go home (with the understanding that I would pick up the hours later) and/or work from home while doing things like waiting on the vet or babysitting a sick/injured horse. I have actually done that before-- my wireless network reaches to the barn so I set up camp with my laptop and go to town.
In summary, having property set back off the road and knowing my neighbors/neighborhood are the best things for my peace of mind when I’m away at work. So when you are looking at property, be mindful of this, and try to get a feel for the neighborhood before you buy. If there are horsepeople down the street maybe even drop in or call to feel them out and see what the situation is like. Your neighbors can be a great asset, or they can be a huge inconvenience if they are unfriendly!
