As what looks like a busy six-room Inn (I peeked at your availability), I would heartily recommend that you speak to an experienced Inn broker that's familiar with your area. He/she would have a better idea of what a reasonable price would be.
Smaller Inns like mine would generally sell for real estate value alone. Large Inns sell as commercial establishments and sale prices reflect furnishings, customer goodwill, etc. An Inn your size falls into a gray area somewhere between the two.
If you're willing to price it reasonably (99% of Innkeepers don't), a broker can get you more faster and can market it better directly to aspiring Innkeepers. Plus, an Inn broker is familiar with the ins and outs of what selling an Inn entails and is better equipped to handle the paperwork involved. Whatever you pay in commissions is well worth it.
Good Luck, and keep us posted...there are alot of Innkeepers wondering the same thing!
