The rental market is becoming competitive as spring approaches, with rent prices rising nationwide. Potential renters should research different types of properties available, including traditional rental buildings, condos, and housing cooperatives. While rental buildings may have lower upfront fees and be subject to rent regulations, condos and co-ops often have high fees and restrictions on renting. Co-ops, in particular, have a more rigorous application process and may have rules limiting how long a renter can live in the unit.
