Hi.Coming back to this, I'd ask what is your goal/reason for this?
Do you have a cabin and just think "hey, a bit extra pocket money to buy a few more knives would be great" or are you wanting/needing to supplement your income?
If its the latter then the reviews and subsequent work to maintain those is very important and require you to probably do a lot of behind the scenes work to (as I said before) make sure you're covered in case of damage etc etc...
If its the former, then I'd just try and keep it as small as you can, maybe rent it out like a bothy style, the user brings his/her own stuff.
One idea, maybe you could rent it out to people on here first then perhaps rent it out via word of mouth... for instance, I'd pay and stay and then recommend it to someone I trust, passing on your contact email, if they contact you, they might need to say "Scottie outdoors recommended you etc etc" then realistically you're almost only going to get safe guests.
Its a bit of everything really. We are looking at diversification of the croft land (which we are allowed to do), to make some money and give people the potential for and enjoyable holiday in a beautiful location doing what we like to do without some of the restriction imposed by campsites.
It would be like a posh bothy (not glamping). Compost toilet, solar shower and clean cold water available close by. Off grid completely but there is 4G signal!
