The Mortgage Story

Buy to Let Mortgages

Whether you're building a portfolio or buying your first investment property, we find the right buy to let mortgage for your circumstances.

Buy to let mortgages work differently from residential mortgages. Affordability is assessed primarily on the rental income the property is expected to generate rather than your personal earnings, and the minimum deposit is typically 25%. For landlords who are self-employed, expats, foreign nationals, or operating through a limited company, additional complexity applies, and that’s where specialist expertise matters.

We work with landlords at every stage, from first-time investors purchasing a single rental property to experienced portfolio landlords with multiple properties and complex structures. We have direct access to specialist buy to let lenders including those who cater specifically to expat and foreign national landlords.

How does buy to let mortgage affordability work?

Unlike residential mortgages, buy to let lending is primarily driven by the expected rental income rather than your salary. Most lenders require the monthly rent to cover 125–145% of the monthly mortgage payment at a stressed interest rate (typically 5–5.5%). This is called the rental coverage ratio or interest coverage ratio (ICR) test.

For example, if the mortgage payment is £800/month, the rent would need to be £1,000–£1,160/month to satisfy the stress test. If the rent falls short, some lenders will allow your personal income to bridge the gap. Getting the rental income assessment right is critical, we know which lenders apply the most favourable criteria for your property type and location.

Buy to let for expats and foreign nationals

Expat and foreign national buy to let mortgages are one of our most common specialisms. A growing number of specialist lenders actively welcome overseas investors, provided they meet deposit requirements (typically 25–30%), the property passes the rental income stress test, and, for foreign nationals, there is a valid visa with sufficient time remaining.

We have placed buy to let applications for clients based in the UAE, Singapore, Hong Kong, Australia, the USA, Canada, and across Europe. If you are living overseas and looking to invest in UK property, get in touch, this is exactly the type of case we excel in.

There's a few factors that need to be considered when it comes to arranging a buy to let mortgage

Deposit

The minimum deposit for most buy to let mortgages is 25% of the purchase price. Some lenders will consider 20% for applicants with strong profiles and lower-risk properties, but 25% is the standard baseline. For expats and foreign nationals, most specialist lenders require 25–30%. A larger deposit gives you access to lower loan-to-value tiers with more competitive rates and a wider choice of lenders.

Residential Status

Your residential status is a significant factor in determining which lenders will consider your application. For UK residents, the full range of buy to let lenders is available. For UK expats, British citizens living overseas, a specialist pool of lenders offer expat buy to let mortgages. For foreign nationals, non-UK citizens, the lender pool is smaller but there are specialist lenders who actively welcome applications.

We will quickly identify which lenders are appropriate for your specific residential status and build your application accordingly.

Personal Income

Many buy to let lenders have a minimum personal income requirement, typically £25,000 per year, as a backstop even though the mortgage is primarily assessed on rental income. However, some specialist lenders have no minimum income requirement, particularly for experienced landlords with an established portfolio. If you are below the income threshold for standard lenders, we can identify those with no minimum income requirement for your application.

Rental Income

Rental income is the primary driver of buy to let mortgage affordability. Most lenders require the projected monthly rent to cover 125–145% of the monthly mortgage interest at a stressed rate. This figure is typically provided by a RICS-accredited surveyor or letting agent as part of the mortgage valuation process. Properties with strong rental yields in high-demand areas generally perform best on this test. We can advise on how the rental income assessment is likely to work for your specific property before you apply.

What are the costs involved with a buy to let mortgage?

As with any mortgage, there are always costs involved and buy to let mortgages aren’t any different. There are the obvious costs such as your deposit and monthly mortgage payments, but you do also need to factor in other costs as there are typically additional costs associated with buy to let properties.

You'll have to factor in things like Stamp Duty Tax and other purchase charges such as application or arrangement fees, as well as being taxed on your rental income. You might also need to consider insurances such as buildings and contents as well as landlord insurance. In order to learn more about things like Stamp Duty Tax and rental income tax, we would recommend speaking with a qualified tax advisor.

If you are looking to find a tenant to live in your property, you might need to pay for advertising to attract potential tenants. You might also go down the route of paying an estate agent to market your property and potentially manage it too so you would also need to account for these costs.

Once you have a tenant in the property, it is your responsibility as a landlord to cover the costs of maintenance and any repairs.

So, if you’re looking to invest in property, it’s important to consider all of the costs involved to make sure that it is a worthwhile and profitable investment.

How much can I borrow for a buy to let mortgage?

The amount that can be borrowed for a buy to let mortgage will be determined by the projected rental income that the property is likely to generate. Lender's use a calculation called a 'stress-test' to determine the maximum amount that can be borrowed based on the rental income. Each lender has their own stress-tests and some are more lenient than others which may mean that you could borrow slightly more with one lender compared to another. 

In addition to this, the majority of mortgage lenders will also want to see that you to have another income stream, whether that be from employment or from self-employed income. The reason for this, is that you are going to need to be able to cover the mortgage payments, in the event of any rental voids when you don’t have tenants.
