I think this business carries an element of risk that means if you need to bring in 1500 pcm to afford to give up your job, it's probably not the venture for you.
Is that 1500 pcm for twelve months of the year?
I have a friend who was running a cute little AirB&B on the edge of a really touristy place, very popular with walkers. It was £50 a night in March 21; by winter 22 she had to put her price up to £75 a night because the cost of heating it had gone up so much. Come April 23 when she'd usually get booked at least half the nights of the month, she had 4 individual nights booked.
The bottom just fell out the market in her area. Maybe people wanted to go abroad and get people to cook and clean for them for the same money? Idk.
Also, someone nearby opened something bigger and fancier.
I was shocked when she told me, so I looked within a 5 mile radius during the coronation weekend - a bank holiday - when I would be expecting lots of families would be getting away for a long weekend. I couldn't believe how many of the venues were still bookable. And at prices I thought seemed better value for money than the last time I'd looked.
They're very affected by weather, as are a lot of these ventures, I believe.
For me (a very risk adverse person), if I NEEDED an income, this wouldn't be the route I would take.
my friend who has a one bed annexe thinks this is achievable-
How many bookable nights has she been booked out for over the last 12 months? Because that's what my friend has, a one bed annexe. Are you sure she's not just buttering you up to move to her area because she likes your company? :)
