If the host department/ home university wish to support the guest researcher financially with the rental payments, this is best done by a grant to the researcher in question so that they can pay online through their housing account.
If this is not an alternative we can offer to internally/externally invoice the department instead of sending the invoices driectly to the guest researcher.
If you wish to be invoiced you can choose to either:
Pay the entirety of the guest researchers stay directly (maximum 1 year).
Pay three months at a time for the stay.
When a guest researcher pay themself, the rent is paid monthly, as normal practise in Sweden.
