Understand the mortgage alongside the wider decision
A buy-to-let mortgage is designed for a property that will be rented to tenants rather than occupied as your own home. Whether you are considering your first rental property, adding to an existing portfolio or reviewing the borrowing on a property you already let, the mortgage is only one part of the decision.
Lenders may consider the expected rent, the amount you want to borrow, your personal circumstances, your experience as a landlord and the type of property and tenancy. We can help you understand the questions a lender is likely to ask, compare suitable mortgage options and prepare an application around the details of your plans.
Mortgage types
What is a buy-to-let mortgage?
A standard residential mortgage is intended for a home occupied by the borrower. A buy-to-let mortgage is normally used where the property will be let to tenants. The lender therefore needs to understand both the borrower and the proposed rental property.
Many buy-to-let mortgages are arranged on an interest-only basis, although repayment options are also available. Rates, fees, early repayment charges, deposit requirements and property criteria can differ from residential mortgage types. Some buy-to-let arrangements fall within a consumer buy-to-let framework, while other forms of buy-to-let mortgage are not regulated by the Financial Conduct Authority.
The right route depends on how the property will be used, who will own it and whether the application is being made as an individual or through a company.
Rental assessment
How lenders assess a buy-to-let mortgage
The expected rent is usually central to a lender's assessment. A valuer may provide an opinion of the property's market rent, and the lender can test that figure against the proposed mortgage payment using its own rental coverage calculation and stressed interest rate.
That calculation is not the same across the market. Depending on the lender and circumstances, personal income, tax position, landlord experience, existing borrowing and the wider portfolio may also be considered. Some lenders can take account of personal income where the rent does not meet their usual calculation, but this is not available or appropriate in every case.
An advertised rent is not a guarantee of the figure a lender's valuer will use, and a mortgage being affordable under lender criteria does not by itself mean the property will meet all of its real-world costs. We will explain the assessment used by a suitable lender and the information required before an application is submitted.
Talk through the lender assessment
Your contribution
Deposit, equity and loan-to-value
For a purchase, the deposit is the difference between the price of the property and the amount borrowed. For a remortgage, the equivalent is the equity left in the property after the proposed mortgage is taken into account.
Loan-to-value, often shortened to LTV, expresses the mortgage as a percentage of the property's value. For example, borrowing £180,000 against a property valued at £240,000 would be 75% LTV. This is an illustration of the calculation, not an indication that a particular product or loan amount will be available.
Buy-to-let mortgages commonly require more deposit or equity than a residential mortgage, but there is no single minimum that applies to every applicant or property. The available LTV can depend on rental coverage, property type, ownership structure, experience, credit profile and lender criteria. A larger deposit may widen the options available, but it should be considered alongside purchase tax, legal costs, refurbishment and a reserve for ongoing expenses.
Your background
First-time, experienced and portfolio landlords
First-time landlords may be buying their first rental property while already owning their own home, or they may be first-time buyers as well as first-time landlords. Lenders treat these situations differently. Some accept them and others require previous ownership or landlord experience.
Existing landlords may need to provide details of current properties, mortgages, rents and commitments even where the new application relates to one property.
Portfolio landlords are assessed under lender-specific portfolio rules. The lender may review the performance and borrowing across the portfolio, not only the property being purchased or refinanced. The definition of a portfolio landlord and the documents requested can vary, so the position should be checked before choosing a product.
Tell us about the full picture at the outset. This helps avoid selecting a lender whose criteria do not fit the applicant or wider portfolio.
The proposed property
The property and the tenancy matter
Buy-to-let lenders do not assess every property in the same way. Construction, condition, value, location, lease length, service charges and demand for the proposed tenancy can affect whether a property is acceptable. Flats above or near commercial premises, new-build properties, houses in multiple occupation and properties requiring substantial work may need a more specialist approach.
The intended use must also be clear. A standard single-tenancy buy-to-let, a house in multiple occupation, student accommodation, a holiday let and short-term accommodation are not interchangeable. They can involve different mortgages, planning requirements, licences, insurance and management responsibilities.
Do not assume that a mortgage labelled buy-to-let permits every type of letting. The proposed tenancy and occupancy should be disclosed accurately to the lender and checked with the solicitor, insurer and relevant local authority where necessary.
Repaying the mortgage
Interest-only or repayment?
With an interest-only mortgage, monthly payments normally cover the interest charged but do not reduce the original capital balance. The full balance remains to be repaid at the end of the term. A clear and credible plan is therefore needed for repaying it, which may include selling the property, using investments or refinancing if suitable products remain available at that time.
With a repayment mortgage, each scheduled payment includes interest and part of the capital, so the balance should reduce over the agreed term if all payments are made. Monthly payments are normally higher than on an equivalent interest-only arrangement.
Neither method is automatically right for every landlord. Cash flow, tax advice, the investment timescale, future plans and the risk of relying on a later sale or remortgage should all be considered.
Running the property
Plan for running costs and landlord responsibilities
The rent is not the same as profit. A realistic budget should allow for periods without a tenant, repairs, maintenance, safety checks, buildings and landlord insurance, letting or management fees, service charges, ground rent where applicable, licences, accountancy, tax and legal costs. It is also sensible to test how the budget would cope if mortgage costs rise or an urgent repair is needed.
Landlords have legal and safety responsibilities, and the detail differs across England, Scotland, Wales and Northern Ireland. Requirements may also vary by property and local authority. Mortgage advice does not replace advice from a solicitor, accountant, letting professional or local authority, but the likely costs and property use should be considered before borrowing is arranged.
Keep a contingency reserve rather than relying on uninterrupted rent. Rental income and property values can fall as well as rise, and there is no guarantee that a property can be sold or refinanced when planned.
Ownership structure
Buying personally or through a limited company
Some landlords buy in their own name and others use a limited company, often a special-purpose vehicle. A company is not automatically the better or cheaper route. Mortgage choice, rates, fees, guarantees, administration, how money is taken from the company and the tax consequences can all differ.
The ownership decision should be made before committing to a purchase. Changing the structure later can involve a property transfer, fresh legal work, tax and a new mortgage application. Obtain tailored tax and legal advice from appropriately qualified professionals; Anderson Reed Financial Services can then explore mortgage options that fit the chosen structure.
Company terminology
What is a buy-to-let SPV?
SPV means special-purpose vehicle. In buy-to-let lending, the term commonly describes a limited company established for a restricted property-related purpose rather than a company carrying on a wider trading business. Lenders that accept company applications may look at the company's activities, directors and shareholders, and can require personal guarantees from directors.
An SPV does not create an automatic mortgage or tax advantage, and not every limited company will meet every lender's definition or criteria. The activities recorded for the company, its ownership, previous trading and the proposed property can affect the mortgage options available. A lender may also treat an established trading company differently from a newly formed property SPV.
The decision to buy personally, use an SPV or use another structure should be made with qualified tax and legal advice before contracts are exchanged or money is committed. Anderson Reed Financial Services does not set up companies or advise on their tax or legal suitability, but we can explain how the chosen structure may affect the mortgage search.
Buying costs
Property purchase taxes across the UK
An additional-property tax charge may apply to a buy-to-let purchase, but it is not accurate to describe every buy-to-let purchase as having one universal stamp duty charge. The tax system depends on where the property is located, the purchase price, what the buyer already owns, whether a previous main residence is being replaced and whether the purchaser is an individual or a company.
- In England and Northern Ireland, the relevant tax is Stamp Duty Land Tax and higher rates may apply to additional residential property.
- In Scotland, Land and Buildings Transaction Tax applies and an Additional Dwelling Supplement may also be due.
- In Wales, Land Transaction Tax has separate higher residential rates.
Tax rules and rates can change. Our Stamp Duty Calculator is a guide for England and Northern Ireland only; obtain a transaction-specific figure and legal or tax advice before exchanging contracts or making an irreversible decision.
Existing rental properties
Buy-to-let remortgaging
An existing landlord may remortgage to review a maturing deal, change the mortgage structure, raise funds or move borrowing to a different lender. The new lender will normally reassess the property, rent, loan-to-value and applicant rather than treating the change as automatic.
Before switching, compare the full cost rather than the headline rate alone. Early repayment charges, arrangement fees, valuation and legal costs, a change in monthly payment and the remaining term can affect the outcome. Raising capital increases the debt secured on the property and may reduce the buffer available if its value or rent falls.
If staying with the current lender through a product transfer is available, it can be considered alongside remortgage guidance. You can also use our Mortgage Repayment Calculator to explore repayment examples, but it does not perform a lender's buy-to-let rental assessment.

Common questions
Frequently asked questions
How much deposit do I need for a buy-to-let mortgage?
There is no single deposit that applies to every buy-to-let mortgage. The available loan-to-value depends on the lender, expected rent, property, ownership structure and applicant. We can check the relevant criteria without presenting one percentage as a market-wide minimum.
Can I get a buy-to-let mortgage as a first-time landlord?
Potentially. Some lenders accept first-time landlords, while others require property ownership or landlord experience. A person who has never owned any property may have fewer options than an existing homeowner, so the exact background matters.
How is buy-to-let affordability assessed?
Lenders commonly compare the expected market rent with a stressed mortgage cost using their own rental coverage calculation. Some also consider personal income, experience and other properties. The calculation and evidence required vary by lender.
Can I live in a property with a buy-to-let mortgage?
A standard buy-to-let mortgage is intended for a property let to tenants, not for the borrower or close family to occupy as their home. If you or a family member may live there, tell the adviser before applying because a different mortgage and regulatory treatment may be required.
Should I choose interest-only or repayment?
Interest-only can reduce the scheduled monthly payment but leaves the original capital to be repaid at the end of the term. Repayment normally costs more each month but reduces the balance over time. The choice should fit the budget, timescale and repayment plan.
Can I buy a rental property through a limited company?
There are buy-to-let mortgages for eligible companies, but the criteria, costs and guarantees can differ from personal borrowing. A limited company is not automatically more tax-efficient, so obtain tax and legal advice before deciding how to buy.
What does SPV mean in buy-to-let?
SPV means special-purpose vehicle. It commonly refers to a limited company set up for restricted property-related activities. Lenders have different definitions and criteria, and an SPV is not automatically the right ownership or tax structure. Obtain qualified tax and legal advice before establishing a company or committing to a purchase.
Can Anderson Reed Financial Services put me in touch with a solicitor or tax adviser?
Anderson Reed Financial Services can explain how a chosen ownership structure may affect the mortgage search. Obtain qualified tax and legal advice before deciding how to buy or committing to a purchase.
Can I remortgage a buy-to-let property to raise money?
It may be possible, subject to the property value, rent, loan-to-value, purpose of the funds and lender criteria. Increasing the mortgage raises the debt secured on the property and should be tested against future costs and periods without rent.
Are buy-to-let mortgages regulated by the FCA?
The regulatory position depends on the circumstances. Some consumer buy-to-let activity falls within a specific framework, while some forms of buy-to-let mortgage are not regulated by the Financial Conduct Authority. Anderson Reed Financial Services will explain which process applies to the proposed case.
