I have holiday cottages. The person who says you pay more for utilities in incorrect. Also, if you mainly rent it out you pay busines rates, but currently you get small business rates relief so you pay nothing.
As you are cash buyers, the return you will get will be way higher than you could get anywhere at the moment. The stock market- where you can get good returns- is too risky at the moment in my opinion.
The most profitable are cottages for couples. Our one bed was full for 48 weeks last year.
We have a 3 bed as well. The returns are much less on that, as although you get a lot in school holidays it doesn't get November,January and February unless we discount to what we would get for the one bed.
You shouldn't get an agency to manage it. They charge a bomb! Get a local person who will do the cleaning and laundry for you.
You get more money using Air BnB we have found. The admin from your end is very easy and straightforward. Lots of people only look there these days, so it is the volume of bookings that gets you the profit. We do short breaks year ound on our one bed, full week only for the 3 bed.
If you approach a small local agency- or even a big one like Classic Cottages- they will give you a projection of earnings for a cottage you are looking at.
Our 3 bed makes around £6.5k a year profit after all expenses, if we didn't have a mortgage on it it would be £12.5 k. That includes paying a cleaner £95 per changeover for cleaning and laundry.
The one bed made £21k last year - no mortgage. If we used a cleaner we would pay £95 per changeover and we did 60 changeovers. This one is marketed as luxury. I spent maybe £3k more than I would have on fixtures and fittings.
Also, the tax breaks are way better on holiday let's than long term. You can claim capital allowances for any work you do and capital gains tax is lower when you sell. You can also offset mortgage interest payments.
Our cottages are my job, so it is slightly different and I live next door. I did used to run them remotely before I moved here and had a trusted team of tradespeople I could call on, all found by word of mouth.
At the end of the day it's location, location location. If you are in a tourist hot spot with year round trade then it is a good idea.
