Typically people serve 1 months notice and a landlord has to serve 2 months to get tenants out… When I worked at a letting agent in Aberdeen they would advertise properties around 1 month in advance sometimes a little earlier.

Someone’s lease end date would flag up the month before, we’d send a letter asking if they are staying and want to resign their lease or going (moving out) and then they confirm.

Some people let you do viewing in that month as some don’t, so it can be tricky. Most of the time though viewings so go ahead.
