60-Second Summary – Santander Buy to Let Mortgage Review 2024

A buy to let mortgage is a mortgage for any property that you intend to rent out and don’t plan to live in yourself. There are a few different types of buy to let mortgage, such as single property, multi property, and commercial buy to let mortgages.

This can all feel a bit complicated if you have never applied for a buy to let mortgage (or any mortgage) before. Mortgage lenders will all have slightly different rates and rules for buy to let mortgages. Our Money Mum and Dad’s aim is to explain more about how Santander buy to let mortgages work – and help you save money in the process!

  • Santander offers a variety of competitive buy to let mortgage options, including fixed and tracker rates, with product fees ranging from £0 to £1,749.
  • To apply for a Santander buy to let mortgage, you must be at least 21 years old with a minimum income of £25,000 per year. You will also need a deposit of at least 25% for houses, and 30% for flats.
  • You can convert an existing Santander mortgage into a buy to let mortgage, but you will need to speak to Santander directly to arrange this. You can’t rent out a property with a standard Santander mortgage unless you receive written permission from Santander first.
  • Existing Santander customers can sometimes access better interest rates, so it’s worth checking this before switching to a new lender for your buy to let deal.
  • If you have a low credit score, Santander might not be the right choice for your mortgage. You should check your options with multiple lenders and ask a qualified mortgage broker if you need more advice.

Santander is a popular option for UK buy to let mortgages, offering a wide range of mortgages for landlords and property investors. If you are considering becoming a landlord or adding to your property portfolio, Santander offers several different mortgage options.

Santander does have some strict rules around buy to let properties, and you are not allowed to rent out your home if you have a standard Santander mortgage. You will need to get written permission from Santander to rent your home or you will need to convert your mortgage to a buy to let mortgage.

For more information about converting a residential mortgage to a buy to let mortgage with Santander, you can read their full mortgage guide – CLICK HERE

Note: This includes renting out any part of the property (e.g. taking in a lodger who only rents a single room).

Santander buy to let mortgages work similarly to most mortgage types, and you will need to provide a deposit and prove your income during the application process. This can be in the form of payslips (employed) or self-assessment tax returns (self-employed).

Once your mortgage has been approved, you will repay the amount that you have borrowed each month until your mortgage has been fully repaid. Most buy to let mortgages will be interest-only, which means that you only need to repay the interest each month. You will need to prove to Santander that you have solid plan in place to repay the full loan amount at the end of your mortgage term.

Here’s some of the main points about Santander buy to let mortgages:

  • Portfolio landlords can’t have more than 4 properties with a Santander mortgage. If you wanted to buy more properties, you would need to use a different lender. You can still switch to a new mortgage product with Santander after a fixed or tracker rate deal ends.

  • If you have had a Santander mortgage for 6 months or longer, you can contact Santander to switch to a buy to let mortgage. Your other option is to get written permission to let your property, but this will come with a fee of £295.

  • If your Santander buy to let mortgage deal is coming to an end, you will need to call Santander to lock in a new tracker or fixed rate deal. If you leave it, you risk being moved to Santander’s Standard Variable Rate which could cost you far more each month.

  • If you are on a tracker rate, you can make a switch to a new deal at any time without paying any early repayment charges. If you are on a fixed rate deal, you might be better off waiting until you are within the last 6 months of your deal or you will need to pay fees.

  •  If you choose Santander for your buy to let mortgage, you will benefit from a free property valuation (for properties worth up to £2.5million), as well as either your standard legal fees paid or £250 cashback.

You don’t need to be a current Santander customer to apply for a Santander buy to let mortgage. However, if you are new to Santander, you will need to apply for your mortgage through a mortgage broker. This is because Santander only accepts direct applications for buy to let mortgages from current Santander mortgage customers.

Santander buy to let mortgage lending criteria:

  • You must be between the ages of 21 – 85 years old when you apply.
  • You must already own either a residential or buy to let property.
  • You need to have a minimum income of at least £25,000 (only one applicant needs this if a joint application).
  • You must be borrowing between a minimum of £75,000 and a maximum of £750,000.
  • You will need to have a minimum deposit of 25% (house) or 30% (flat) of the property’s value.

The amount that you will be able to borrow from Santander will depend on various things such as your usual income, credit score, and the amount you have saved as your deposit.

For most Santander buy to let mortgages, you need to be borrowing between £25,000 – £750,000 which is fairly flexible as most investment properties will fall within this price range. If you’re not sure of how much you might be able to borrow, you can use the Santander buy to let mortgage calculator which is found HERE on their website.

Below are the main pros and cons for Santander mortgages, which you can use to help you decide if Santander is the right choice for you. You should always consider all your mortgage options carefully, and compare multiple rates to ensure that you choose a deal that is affordable for you.

Can convert an existing Santander mortgage into a buy to let mortgage if needed.Your monthly repayments can change over time if you are on a tracker rate deal, so they could increase.

Mortgage lenders can often offer better rates to their existing customers, so you should think about this if you were considering switching from Santander to a new lender.

You may even be able to get a better mortgage rate if you are a Santander banking customer, so it’s certainly worth asking about this if you’re not sure. The easiest way to find out whether Santander can offer you a better rate is to contact them directly or speak to a mortgage broker who can compare multiple deals for you.

If you’re thinking about becoming a landlord for the first time, there are a few important things to be aware of and a few easy ways to get some extra financial support.

  1. The Gov.uk website has a full section of guides which explain things such as how to check a tenant’s right to rent and how to use a deposit protection scheme. There is also a guide about evicting tenants, if you unfortunately needed to do this for any reason.
  2. Your tenants will want to know things like what your property’s energy performance is like and you can request a new Energy Performance Certificate (EPC) HERE.
  3. Having Landlord’s Insurance can protect you against damage to your property. Santander partners with AXA and may offer to set this up for you during the application process. It is often better and cheaper to shop around for a few quotes, rather than going with your bank’s recommended insurer.
  4. You may be able to access a grant which can be used to make improvements to your rental property. An example of this is the ‘Energy Efficiency Grant’ which helps with the cost of new insulation, solar panels etc. Housingrights.co.uk has published a full list of all the available grants HERE.

If you are new to Santander, you won’t be able to apply for your buy to let mortgage with them directly.

Using a mortgage broker can be a good idea anyway, as this offers you additional help and support with your application. This can be especially useful if this is your first time applying for a buy to let mortgage and you are not familiar with the requirements of this mortgage type.
