To furnish, or not to furnish. A landlords problem
I would say go unfurnished. Furnished isn’t even a sensible option. I know many landlords provide furniture, and there are some exceptions where it makes sense (e.g. holiday lets, student lets, HMOs etc), but mostly, don’t get caught up in the cost.
Furniture creates so a hassle (e.g. disputes over theft and damage), and the rent difference between furnished and unfurnished is negligible.
This also includes unnecessary fittings, like shelves. Bear in mind, shelves alone won’t generate extra rent, so why provide them?
The blatantly obvious point to remember is that the more you provide with your property, the more you’re making yourself responsible for; if you provide a sofa and it comes to the end of its life, then you have to replace it. Each item you provide is like writing blank cheques.
If you are a reluctant landlord, and you’re having to move away for work then put in the contract and inventory “furniture and items listed are for tenants enjoyment, the landlord will not take responsibility for repairs or replacement.“
