Dataset Help With An Assignment(house Prices)

Hello everyone,

I have been having trouble finding a dataset for an assignment including house prices,past and present.The assignment is to make a model that takes in user input(for example the price of the house currently,rooms,bathrooms,square footage etc) and then gives a prediction on the price of the house.I have searched for a lot of datasets and all of them have price indexes and not the actual prices. Open to suggestion using the price indexes too but i have no idea how i would use them.Also the assignment is in python.
