A rentals loan, also known as a rental property loan or a buy-to-let loan, is a type of financing that allows individuals or businesses to purchase or refinance rental properties. The loan is secured by the rental property and is typically based on the property's income potential rather than the borrower's personal income or credit score.

Rentals loans can be used to purchase or refinance a variety of rental properties, including single-family homes, multi-unit apartment buildings, and commercial properties. The terms of rentals loans may vary depending on the lender, but they typically offer longer repayment periods and lower interest rates compared to traditional mortgages.
