We have finally exchanged on our house and have a completion date. We move out on completion and hand in the keys that day. The buyer will be renting out the house. How clean are we expected to leave it? Should we get in professional cleaners or is that up to the buyer, considering we will have such a small window from when the removal company comes in and when we are out? We did ask for an extra day but the buyer is keen to move tenants in the day after completion.
