The only thing you have to worry about is if immigration want to visit the house when under consideration for the extension. They will want to see you in and outside the house and take pictures of the sign showing the address with you next to it
You will have to get your stamp transferred from wherever you got your last visa or extension. You MAY be extensively interviewed at the border/airport on entry enquiring why you are not in class. They may follow up with visits to your place of education and interview the staff.
