doesnt cost much ....i got a 3 bedroomed place so there is always 2 spare bedrooms...if they are new to the country it can be a little tiring helping them find their way around...sort out the mountain ofn paperwork involved in becoming a resident & eventually a citizen...so it is a bit annoying when a fresh bright eyed bubble butted specimen departs soon after I've set him up....but thats life i guess...nothing is guaranteed...
