But now one son and one son-in-law want to do something with brewing beer and owning a brewery-bistro or something (not privvy to all the details at this point) and I'm terrified for them.

In most states where I've done business, if there is no early termination clause, usually you can charge for the costs to advertise and the time it is vacant including utilities if tenant was responsible for them up until lease end, itemized with the rest of the damage above normal wear and tear. 

@Larry Fried @Robert Naucke JrThanks Larry for the correction, well taken.I found your article, please can you give me more details about this company.

Take though time to dig and get the details and the bank will finance.

This is difficult to answer without more details.

There are some possibilities pls connect for details.

This is one of those items that you know you might deal with as a landlord, it's one of the risks.

If that house is still available I would get it under contract as soon as possible as a primary residence and then figure out the details in the coming weeks/months.

What items in particular are giving you the most trouble and wearing out?

Or maybe an article that explains this in further details would be great.
