@Adrian3010 You have 2 options
1) look at rates for similar places on Airbnb and then guestimate what your occupancy might be
2) Buy data from Airdna or Airdata if they cover your town.
then build a business plan.
Don't forget you may need to change your insurer and mortgage company as short term rentals are often not covered by buy to let providers
Then research the tax and pension benefits of STR over buy to let
Then make a decision and hope you don't regret it.
You can also find really good 2nd hand furniture on Facebook marketplace/ebay.
