To summarise: we rent out our basement flat to short-term visitors, usually academics on study grants. I ask for a security deposit which is returned after they move out and any damages/phone calls, etc. paid for from the deposit. Many, though not all, are from overseas and deposit is paid by electronic bank transfer. When I return the deposit to an overseas bank, my bank charges me £25 transfer fee. I have suggested that I will return deposit by sterling cheque (at no cost to me from my bank) which they can deposit (and pay their banks fees, if any) or we split the cost of the bank fee. Some tenants, however, think I should pay the whole cost. I think in future I will clarify in the contract that they pay costs of dealing with foreign banks, but it does seem obvious to me that the buyer should pay. If you buy something in Euros the seller doesn't receive a lower price, but your bank will normally add a foreign currency transaction charge or somesuch, right? What do you think?
