Rent at Fair Rental Price

I have a investment home and I rented it out by rooms. During 2024, I decided to switch to renting out the entire house instead of renting by rooms, for some reason. Most tenants moved out within a two months period but the last tenant refused to move out before his lease ended. He stayed in the house for three more months. For that three months the rental income was just several hundred dollars per month, but the fair rental price in that area is around $2,500. How do I answer the question:" did the property always rent at fair rental price?" and can I deduct depreciation and expenses for the three months as usual? Thank you!
