Rental properties are real estate units that are leased or rented out to tenants. These properties can include single-family homes, apartments, condos, and commercial spaces. Landlords own these properties and earn income by charging rent, which can vary based on location, size, and amenities. Tenants who rent these properties typically sign a lease agreement, which outlines the terms of the rental, including the duration, payment schedule, and responsibilities for maintenance. Rental properties can be a good investment for landlords, providing a steady income stream and potential appreciation in value over time.
