Absolutely not @Olivia736 you should set your pricing based on
1. Having created a profit and loss budget to identify all the costs associated with running your Airbnb. Then estimating how many nights a year you are likely to let your place out for. Divide total costs by estimated number of nights. This shows you how much you need to make to break even.
2. Look at what your local competitors are charging.
So if your net costs are £100 a night and your local competitors are charging £150 a night that gives you an idea of what you can charge and your likely profit levels.
