Buy to Let Mortgages

Unlock Your Property Investment Potential

Investing in property is an exciting opportunity, but securing the best buy-to-let mortgage can make all the difference in maximizing your returns. Whether you're purchasing your first rental property or expanding your portfolio, we're here to help.

What Is a Buy to Let Mortgage?

A buy-to-let mortgage is designed for property investors who want to purchase property to rent out. Unlike residential mortgages, these loans are assessed on the potential rental income of the property rather than just your personal income.

Key features of a buy-to-let mortgage:

Higher Deposits: You'll typically need at least a 25% deposit, though some lenders may require more depending on the property and your financial situation.

Interest Rates: These are often slightly higher than residential mortgages due to the nature of the investment.

What Kind of SPV Code Is Needed for a Limited Company Buy to Let?

If you're considering a limited company buy-to-let mortgage, setting up a Special Purpose Vehicle (SPV) is a key step. An SPV is a type of limited company created specifically to manage property investments.

Lenders usually require your SPV to have a specific Standard Industrial Classification (SIC) code that aligns with property letting and management. Commonly accepted SIC codes include:

  • 68100: Buying and selling of own real estate.

  • 68209: Other letting and operating of own or leased real estate.

Using the correct SIC code ensures that lenders recognize your company as a legitimate property investment vehicle, improving your chances of mortgage approval.

Why Is an SPV Important?


An SPV makes the process of obtaining a buy-to-let mortgage under a limited company straightforward, as lenders prefer this structure for its simplicity and focus on property activities.

 

Not sure where to start? Our mortgage brokers can guide you through setting up an SPV and choosing the right SIC code to meet lender requirements.

How Much Deposit Do I Need for a Buy to Let Mortgage?

For a standard buy-to-let mortgage, most lenders require a deposit of around 25% of the property value, though it could be higher depending on individual circumstances.

 

For example, if you're purchasing a property worth £200,000, you’d typically need at least £50,000 as a deposit.

Having a larger deposit can:

✅Increase your chances of approval.

✅Give you access to better interest rates.
