Buy-to-let mortgages
Property finance built around the investment.
From a first investment property to larger portfolios and limited company borrowing, our advisers help landlords understand lender criteria, rental calculations and the finance available for their property plans.

Property investment
Buy-to-let lending is assessed differently from a residential mortgage.

The property's expected rental income can be just as important as the borrower's personal financial position.
Buy-to-let lenders commonly use rental-income calculations to determine the level of borrowing available. Those calculations differ between lenders and can vary according to the applicant, tax position, property and mortgage product.
The ownership structure also matters. A property purchased personally may have a different lender market from one purchased through a limited company or special purpose vehicle.
Who we help
From the first investment property to larger portfolios.
The most appropriate lender can change significantly according to your experience, ownership structure, portfolio and the property being financed.
01
First-time landlords
Clients purchasing their first investment property may have access to a wide range of lenders, although criteria can differ from those available to more experienced landlords.
02
Experienced landlords
Landlords with existing properties may need lenders that understand their wider portfolio, borrowing commitments and long-term investment strategy.
03
Limited companies
Many investors purchase through limited companies or special purpose vehicles, requiring lenders with appropriate company buy-to-let criteria.
04
Portfolio landlords
Investors with several mortgaged properties can face more detailed underwriting of their wider portfolio and overall financial position.
05
Higher-value investors
More substantial investment properties or larger portfolios can involve specialist lenders, bespoke underwriting or private-bank consideration.
06
International investors
Foreign nationals, UK expats and clients with overseas income may require lenders comfortable with international residency and financial circumstances.
Rental assessment
The rent needs to support the mortgage under the lender's calculation.
Buy-to-let lenders typically compare expected rental income with a stressed mortgage payment to assess whether the property can support the borrowing.
The required rental coverage and stressed interest rate can differ significantly from lender to lender, which means the same property may support different loan amounts depending on where the case is placed.

Rental coverage
Different lender calculations can produce different borrowing outcomes from the same anticipated rent.
What lenders consider
The investment, borrower and ownership structure all matter.
Buy-to-let underwriting can extend beyond the rent and property, particularly where there is an existing portfolio or company structure.
01
Rental income
Buy-to-let affordability is often influenced by the rent the property is expected to generate and the lender's individual rental calculation.
02
Deposit & loan-to-value
Deposit requirements differ from residential mortgages and vary according to lender, property, borrowing structure and client circumstances.
03
Personal or company ownership
The way the property is owned can materially affect which lenders are available and how the mortgage application is assessed.
04
Existing portfolio
For landlords with multiple properties, lenders may review existing rents, mortgages, loan-to-values and the performance of the wider portfolio.
05
Property type
Flats, houses, HMOs, multi-unit properties and other specialist property types can each require different lending criteria.
06
Tax & legal structure
The tax treatment of property investment can be complex. Independent tax and legal advice may be appropriate before deciding how to purchase.
Ownership structure
How you own the property can change the mortgage market available.
The mortgage considerations for an individual landlord can be different from those applying to a limited company or wider portfolio structure.
Personal ownership
The property is purchased and mortgaged in the individual's own name, with lender criteria based on the applicant and investment property.
Limited company / SPV
The investment is purchased through a company, commonly a special purpose vehicle, with the mortgage taken by the company and usually supported by personal guarantees.
Portfolio structure
More experienced investors may own several properties across different structures, requiring a lender to consider both the individual transaction and wider portfolio.
Important
Mortgage advice and tax advice are different. The most appropriate ownership structure should not be selected solely because of mortgage availability. Independent tax and legal advice may be required.

Portfolio landlords
As the portfolio grows, underwriting can become more detailed.
Lenders may need to understand the wider portfolio rather than assessing only the property being purchased or refinanced.
Existing mortgage balances, rental income, property values, loan-to-values and overall portfolio performance can all become relevant to the lending decision.
Property types
Not every investment property fits standard buy-to-let criteria.
The property itself can determine which lenders are appropriate. More complex investment properties may require lenders with specialist valuation or property criteria.
