In brief: Posibilities

My first thought would focus on the nasal airway.
If you have allergies/irritants/sinus swelling that narrows the nasal airway your mouth breathing during sleep will cause a sore throat. This can be aggravated in an environment like a heated house, because low humidity adds to the problem. A humidifier and generous use of nasal saline may give you some relief.
