Middleton is very popular and Land Lords post 60 to 90 days in advance. Check Craig's List but do not ever send money.....drive the neighborhoods and call the numbers on the signs. Because Middleton is so popular dollars spent on advertising is little. You have to be efficient and quick in your search methods. Target and area you like and watch for turn-over.
Ask other renters where they have had luck in the past....talk to people - word of mouth is sometimes your best bet.
