Your school subject is not college. It is probably economics.
On the demand side, think of things that affect the demand for housing in a particular location. e.g., distance from employment centers, quality of schools, property taxes, government services, etc. Also, consider short run and long run issues.

On the supply side, think of things that affect the supply of housing in a particular location. e.g., local wage rates, access to materials, zoning laws, etc.
