My home visit is today. The first time I did it the surveyor stuck his head in each room and was out in five minutes. This time it could be different but considering the state of the places I've moved into, I am hoping not! They're looking for damage - not stuff the tenant is responsible for like carpets and paintwork (though if it's really trashed they may ask why) as you sign that you accept the house in the condition you swapped. So the surveyor is looking for punched out doors, missing pipework, broken windows - damage you may have done that you need to put right.
Please God they find nothing on mine today and I can move!
You have a right to move providing you're not in rent arrears, have ASBO type complaints or damage to your home. Ditto for the man you're swapping with. So assuming he and you are OK, it will happen, within 42 days of the forms going in is the usual time frame.
