Since this is a real estate site, I am assuming that you meant, "When can people move in?" If you are a renter, you may move in on the date your lease or rental agreement allows for. If you are the buyer of a home, you are granted possession in accordance with the terms of your purchase agreement. If you are purchasing a home that is currently leased or rented, you may not get possession until the current tenants vacate. As always, contact a real estate professional in your area for the best outcome.
