I would suggest that you check with your local building and zoning dept to see if there is any reason they have for that type of business not being able to locate there. They would be a legal 3rd party that could answer your question. There would be no "feelings" involved if their zoning dept says the business cannot locate there. If it's zoned OK for that type of business, then rent it to the business. Just get a large enough deposit/down payment, and charge enough rent, so if the business folds, and they leave damages and tons of equipment behind, you have their money to get yourselves back to square one again. Remember, you are a business yourself, and you need to keep your own, personal feelings out of a "business" decision.
