From the data you submitted, which was very detailed in daily operations, it looks like you have a hard decision to make.
From what I can see, you have been operating at a loss, for the past 5 years, so it appears. Now that is not necessary bad. In most businesses, the depreciation expense creates passive losses, and so it does not affect cash flow.
What concerns me is that you show negative cash flow for the entire year. You show a cash flow of (21,000) for the entire year, and a high monthly average.
Depreciation should not be showing up in your cash flow, but cash flows affect the business.
If you were to keep the business, you would have to make some changes to increase cash flow, most likely by increasing prices and cutting costs.
The kitchen normally has the biggest drag on cash flows, in most cases. It is difficult for the kitchen to make money, especially in a B&B, where the food and beverage is a staple for service.
Wine and spirits offers the best opportunity to increase cash flows. But I saw little activity in that area.
I wanted to run some scenarios where I could see if you were able to make money on the property during a sell. (using the basic costs and depreciation schedule for the main property). But there was not sufficient information to do that.
My advise to you would be to look at whether or not you can decrease costs and take advantage of the wine and spirits and overcome that cash flow problem. It is hard to run a business using only 4 months of positive cash to cover year long expenses. That is why, in order to survive, resorts and spas have had to develop a model of being a four season operation.
So that is the other thing, is how to turn it into a four season operation.
It may be time to sell. If you are not able to reduce costs, come up with a four season plan, and to do something possible with the wine and spirits, I would say you can not exist this way for long.
It looks like to me it would be time to sell.
I am giving you a copy of a calculator that can be used to see if you can profit form the sell of the property.
Since this is a business establishment use the calculator for either residential or commercial rental.
Certainly by the 7th year, from a realestate perspective you may want to sell.
