Buy/Sell/Rent/Invest Model A model that simulates the dynamics of a real estate market, ultimately aiming to understand how it is affected by vacancy taxes. It has five types of agents: - Buyers: households seeking to purchase a housing unit to live in - Sellers: households that currently own an apartment and are looking to sell it - Renters: a landlord that owns a housing unit and is looking to rent it out - Tenants: a household is currently renting a housing unit - Investors: an agent that owns more than 1 housing unit This is a "Picasso" model (as opposed to a photograph model) [1], meant to be complemented with GIS data as the next step of the research project.
