Unfortunately, that's only a starting point. You have to discount heavily since yours is a small privately-owned hotel, which is generally considered more risky as an investment than buying shares of stock in large hotels and chains whose stock is publicly traded.
And you have to discount for the fact that your 40 percent partner is buying a partnership with you (no offense) instead of an arms-length share in a major company. And it's worse as a 40 percent share, because that means your investor will have to spend a chunk of money worth 40 percent of the value of your hotel, but he or she still has no real control. There are several other ways to establish a value.
You also have to add in some amount for the value of the building and the real estate value of the land.
That's not the only way, however. Some analysts would build a detailed forecast of cash flow for as much as 10 years, and then discount that at a discount rate established to compensate for the present value of future cash flows, and the risk. Others use a technical hotel formula based on capitalization.
And for newer hotels, some will use a formula based on cost to buy and build. Professionals will also look for information they can find on recent private deals with hotels, so they have a basis for comparison. It's not like looking up the value per square foot and doing the math.
My underlying point is that you want to link yourself to some real expertise, as in an attorney, business broker and consultant with experience in selling hotels.
Ultimately, what you'll get is what you can negotiate. After all the formulas and reasoning you can muster, in the end, the price is the price that a buyer will agree to pay you.
