Financing a rental property starts with understanding the mortgage.
Learn how buy-to-let mortgages work, what lenders may consider, how rental income can fit into affordability and which costs and responsibilities landlords should understand before purchasing a property to let.
Rental Property Plan
What is a buy-to-let mortgage?
A buy-to-let mortgage is designed for purchasing a property that is intended to be rented to tenants rather than used primarily as the borrower's own home.
Buy-to-let mortgages can work differently from standard residential mortgages. Lenders may consider expected rental income alongside other factors when assessing an application, and the available mortgage products, rates and criteria can differ.
Four stages to understand before applying.
A buy-to-let mortgage decision involves more than finding a property. Understanding the financing and rental economics can help you plan more realistically.
Choose the property
Consider the property's location, purchase price, condition, likely tenant demand and expected rental income.
Assess borrowing
Review the deposit, mortgage amount, interest rate, term and lender eligibility requirements.
Check rental economics
Compare expected rent with mortgage payments and other ongoing property costs.
Plan for ownership
Allow for repairs, insurance, periods without tenants and other responsibilities of being a landlord.
Rental income can be important, but it is not the same as profit.
Expected rent can form an important part of a buy-to-let mortgage assessment. However, rental income should not be treated as guaranteed profit.
A landlord may need to pay mortgage interest, insurance, maintenance costs, management fees and other property expenses. There may also be periods when the property is empty and produces no rental income.
A realistic rental budget should account for both expected income and potential costs.
What can lenders consider?
Buy-to-let mortgage criteria can differ between lenders. Your application may be assessed using information about the property, expected rent and your wider financial position.
Budget for more than the mortgage payment.
A realistic buy-to-let budget should include the costs of owning and managing the property as well as financing it.
Mortgage costs
Consider the interest rate, mortgage fees, term and any charges that may apply to the product.
Property tax
Property purchases and rental income can have tax implications. Rules depend on your circumstances.
Maintenance
Repairs, upkeep and replacing worn items can create costs during the property's ownership.
Insurance & management
Landlords may need suitable insurance and may also choose to use professional property management services.
The mortgage is only one part of being a landlord.
Buying a property to rent means taking on ongoing responsibilities. These can vary depending on the property, tenancy arrangement and applicable rules.
Buy-to-let is not a guaranteed income strategy.
Rental property can involve financial and practical risks. Understanding them is an important part of responsible planning.
Interest rate changes
Changes in mortgage rates can increase borrowing costs, particularly where the mortgage rate is not fixed.
Empty periods
A property may be vacant between tenancies, meaning rental income can temporarily fall to zero.
Unexpected costs
Repairs, maintenance and other property expenses can reduce the amount left after rental income.
