Buy to Let First-Time Landlord

What are the requirements for a first-time landlord to secure a Buy to Let mortgage?

Traditionally, the first requirement for a first-time landlord is to already own a residential property. Some lenders have exceptions, but the options are more limited if you aren’t a homeowner.

The second requirement is usually to be 21 or over. Again, there are some exceptions, and some lenders may even require an age of 25 plus.

Clean credit always helps, especially with high street banks in the Buy to Let market. You’re also looking at about a 25% deposit for a Buy to Let purchase. You also need to look at energy ratings of A to E on a property to buy.

How much deposit is usually required for a Buy to Let mortgage?

Typically it’s a 25% deposit. That’s the standard. Some specialist lenders will do 20%, but rates are less competitive. Obviously, the more deposit you put down, the better the interest rates you’ll get.

Are there any specific mortgage options for first-time landlords?

Mainstream lenders usually restrict their products to experienced Buy to Let landlords, but there are some options. If you are a homeowner, you can go to any of the high street lenders as a first-time landlord.

There’s a key difference between that and a first-time buyer who’s also a first-time landlord. Some specialist lenders do cater for this, but they are fewer and farther between. Specialist brokers like us can find you those lenders.

How do lenders assess the affordability of a Buy to Let mortgage for a first-time landlord?

Lenders wouldn’t look at your salary, although some do require a minimum income of £25,000. They’re more interested in what the property would generate as a rental income.

That usually needs to cover 125% to 145% of the mortgage payment – which is known as a rental stress rate. That’s calculated with a stressed interest rate of 5.5% or higher in the market right now, as we speak in August 2025. That can change, subject to the product and timing.

What are the common mistakes made by first-time landlords when applying for a Buy to Let mortgage?

A lot of clients underestimate the deposit required. Some hope they can do it with 10% to 15%, but that’s not really available in this market.

Also, remember that stamp duty on second homes has a surcharge of an extra 3%, which is a lot more than people expect [information correct at the time of recording in August 2025].

Bear in mind too that while a mortgage broker or lender might suggest you can get a certain amount of borrowing, that’s subject to valuation. The valuation itself will dictate how much you can borrow. It tells the lender the property value and the potential rental income, which they use to calculate the mortgage size.

Are there any tax implications first-time landlords need to be aware of?

The main thing is the stamp duty land tax – SDLT. It’s going to be more than you will have paid for your residential property, so bear that in mind. Rental income is taxable, and you can get mortgage interest relief, but speak to your accountant about what your income tax will be on that.

Capital gains tax (CGT) is payable when you sell your property. Again, speak to an accountant before you either invest in a Buy to Let property or decide to sell it.
