I got married in my own back yard, which worked out very well. But in my opinion, suitability for a wedding venue really depends on the specifics of the property. Some considerations:
- How many guests can you comfortably accommodate? There are many "boutique" wedding venues out there that accommodate up to 150 people, so there's a lot of competition there in most metros. But not as many venues can handle larger affairs of 200-300 guests, so there's less competition in that niche.
- Do you have adequate parking? Or can you set up shuttle service to a nearby lot?
- Regarding liability, definitely consult an attorney and or insurance agent regarding the type of coverage you need. You'd certainly want to have an umbrella policy in place, in case your business insurance policy doesn't cover everything.
- You mentioned mobile bathrooms (hopefully not port-a-johns). If your setting is rustic, this might work, but I'm not sure that most brides (and brides' mothers) are going to be thrilled about this option.
- Caterers will want/need dedicated kitchen space to heat/prep food. If you don't have dedicated (and out of the way of guests) kitchen space, this can be an issue.
- Your time: most weddings take place on Saturday or Sunday. Are you prepared to spend every weekend either involved in wedding events, or delegating to other folks and making arrangements to be away from your property?
- And the big one: neighbors. They can make or break a wedding venue. Even if you are on a larger property in a rural location, they can still complain if they don't like noise on a Saturday night.
Good luck!
