Amazing insight from everyone and all very prudent.
Sasha,
My advice is in the form of both experiences we had and questions as I find them helpful to stimulate deeper thought and more input in responses from others. I only offer mostly food for thought and some more ideas for evryone to chew on. Certainly no expert or "final word on anything" attitude to be taken from anything I can offer..
We started our place from scratch also and had done several year's worth of research prior to taking the plunge. We read nearly every book we could get our hands on, leaned on many innkeepers of places we had ever stayed at and enjoyed and made a file of everything we hadn't enjoyed over the years of staying in B&Bs as our preferred lodging.
Many of the books available have self-evaluation tests in them to flesh out if you have the personality, tenacity, patience, perseverance, etc.. to become a good innkeeper. Taking these and evaluating the results weighed heavily on our decision to go ahead to proceed.
That being said, these tests did not reveal the ocean of additional things we have since learned about ourselves, human nature, trouble shooting, diplomacy in the face of adversity, pacing ourselves, taking care of ourselves to endure the long, sometimes grueling hours and busy seasons, etc.
Just like many have said, be ready for the unforeseens.
There is a reason why homebuilders, construction companies, etc. build in overage into their estimates, costs, etc. Stuff happens, delays occur, scheduling snafus happen, and even the most highly respected contractors, etc. can flake or not maintain a schedule at times.
Learn all you can about the market you intend to open in.
How saturated is it? Will you realistically be able to compete in a small town with an average number of visitors but a B&B on every corner?
Do most of the established B&B's online availability calendars seem to be mirroring what the area's average annual occupancy rate is? That is easily monitored over time if they use systems that show all their rooms as either booked or vacant.
Does the average room rate for the majority of B&Bs in your chosen destination seem reasonable to you if you are currently a visitor to this area on a regular basis?
How similar are the majority of B&Bs rates or is there big fluctuations on what everybody is charging for what you preceive as similar quality?
What are your income expectations and how many people would be expecting to make a self-sustaining living from the endeavor?
There are exceptions to everything but only in the highest average occupancy rate locations will a small B&B of say 4-5 guest rooms with an average cost of living will a couple doing everything themselves with no staff make morte than a comfortable living at this after expenses.
In many small size B&B cases, ours included, one of the two people very often also works outside the B&B to maintain some steady income, health care coverage, etc.
We feel like we know a lot of innkeepers and in the 4-6 room size, very few of them except for the most established and/or financially secure from other sources does the inn generate enough revenue itself to allow for much more than a comfortable, middle-class lifestyle and usually a very beautiful place to live.
