Buy-to-let mortgages FAQs

If you own a property that you are not living in and would like to rent it out to tenants, then you will need a buy-to-let mortgage to rent it out. It could be classed as mortgage fraud if you rent out a property without a buy-to-let mortgage. You can change your mortgage to a buy-to-let or apply for a consent to let.

If, you have made all your mortgage repayments and own the property, you can rent it out to tenants.

Permission to let gives you permission from your lender to let out your home on a residential mortgage for a specified time. You may need to apply for consent to let if you’re moving into a new property but can’t sell yours.

Your lender can refuse your application for consent to let. If they accept your application, they can charge you. If your application is granted, you’ll still need to take out landlord insurance and ensure the property is habitable for tenants.

Existing TSB mortgage customers can find more information about buy-to-let or consent to let on our dedicated page.

It will depend on the lender’s criteria whether you can let a home on a buy-to-let mortgage to a family member. Family members can be deemed as higher-risk tenants when it comes to rent payments.

Often, the deposit for buy-to-let mortgages is more than a residential mortgage deposit. This is to protect the lender in the event the landlord defaults on their payments, due to issues with collecting rent from tenants.

The deposit for a buy-to-let mortgage is often between 20-40% of the property's value.

How much you can borrow for a buy-to-let mortgage will depend on how much rental income you plan to receive from tenants. Generally, lenders suggest the monthly rental income you receive should be at least 25% more than your monthly mortgage payments. This way, as a landlord you can cover costs like insurance, repairs, and agent’s fees.

It’s important you estimate what you’ll need to spend on the property each year, as well as account for any time the property will be vacant where you won’t be receiving rental payments.
