Independent buy-to-let mortgage advisers

Property finance that fits your wider plans.

An investment property connects to your income, available capital, ownership structure and future plans. The borrowing needs to work across that whole picture.

From a first buy-to-let to portfolio refinancing, company borrowing or specialist rental property, Willow understands what you need to achieve before selecting the financing structure, lender and product.

Start with your plans. We will help you explore the options. Your initial conversation, assessment and presentation of appropriate solutions are free. We explain every cost before you decide whether to proceed.

Start with the investment decision you are making.

Choose the starting point closest to your situation. Ownership, rental income, existing borrowing and capital needs often overlap; we consider them together when assessing the financing.

Investment purchase

Fit the purchase into your wider financial plans.

We consider the purchase alongside your rental and other income, existing debt, available capital and future plans. Ownership and cash reserves are part of the financing decision from the outset.

  • Does the expected rent support the proposed loan under lender stress testing?
  • How does the ownership structure discussed with your tax and legal advisers affect the borrowing?
  • Will the property and intended tenancy fit mainstream buy-to-let criteria?
What determines lender fit

Understand your position and the position behind it.

Rent, ownership and property type shape the borrowing options. Your other assets, commitments, liquidity needs and plans help determine which structure fits. Explore how these considerations connect.

Your initial buy-to-let assessment is free and carries no obligation. We will understand the investment objective, assess the relevant factors and present appropriate solutions before you decide whether to engage us.
One property can raise several financing questions. A single property involving an SPV, overseas income or a capital-raising need can require as much thought as a larger portfolio. The circumstances determine the work involved.
Rent and stress testing Whether the rent supports the proposed loan

Lenders test the rent against a stressed interest payment rather than relying only on the pay rate.

  • Expected monthly rent and valuer confirmation
  • Interest cover ratio and stress rate
  • Tax position, product type and top slicing policy
Read the ICR guide
Ownership structure Personal, limited company or SPV borrowing

Ownership affects the financing as well as tax and legal considerations. We assess lender requirements alongside the structure discussed with your accountant and legal advisers.

  • Personal ownership versus a property SPV
  • Trading-company activity and SIC codes
  • Deposits, director loans and personal guarantees
Read the limited-company guide
Property and tenancy Whether the asset fits lender policy

The same rent can be treated differently according to property construction, tenant profile and intended use.

  • Single lets, HMOs, MUFBs and holiday lets
  • Licensing, planning, leases and commercial surroundings
  • Bricks-and-mortar versus investment valuation

Landlord and portfolio Experience, leverage and background assets

The lender may review the landlord's experience and every mortgaged rental property, not just the new application.

  • Aggregate loan-to-value and rental cover
  • Background mortgages, liquidity and credit
  • Business plan and future portfolio objectives

The Willow investment-finance process

Understand the position. Then structure the borrowing.

Your adviser brings the property and wider financial position together to develop the financing strategy. Our administration team supports the evidence, valuation, underwriting and progress to completion.

01

Understand your position

Discuss your objectives, rental and other income, ownership, existing borrowing and available assets. Establish the capital required, reserves to retain and future plans. This initial assessment is free, with no obligation.

02

Structure and recommend

Assess how the proposed debt fits your cash flow, ownership and wider plans. Compare financing structures, lender criteria, rental stress, costs and flexibility, then explain the appropriate solutions and every cost before you decide whether to proceed.

03

Apply and evidence

Present the full position clearly to the lender, support it with evidence, coordinate valuation and address underwriting questions.

04

Offer and complete

Coordinate with the lender and your solicitor, address offer conditions and keep the financing aligned with the transaction through to completion.

There is no charge for the initial conversation, assessment or presentation of appropriate solutions. Our fee only becomes payable if you choose to proceed, after all costs have been made clear.

What a proper landlord review covers

Make the borrowing work across your wider position.

A purchase or refinance can affect the capital available for your next acquisition, the reserves supporting your properties and the flexibility to sell or restructure later. We assess those connections before recommending the borrowing.

Where appropriate, and with your authority, we work alongside your accountant, tax adviser, wealth manager or solicitor. Their input helps us understand the implications for the financing, while they remain responsible for their specialist advice.

Frequently asked questions

Buy-to-let mortgage questions.

The answers are general guidance. Lender treatment varies according to the borrower, property, tenancy, portfolio and ownership structure.

Ask about your investment
Do you only work with large portfolios or wealthy investors?

No. Our focus is the complexity of the financing need. A single property involving company ownership, overseas income or connected borrowing can require careful structuring. Whether we can help depends on your circumstances and the available lending options.

Can Willow work with my accountant or tax adviser?

Yes. With your authority, we can coordinate with your existing advisers so the financing reflects the proposed ownership structure, company position and future plans. Willow assesses the borrowing; your tax, legal and investment advisers remain responsible for their specialist advice.

Do I need to choose a buy-to-let mortgage before speaking to Willow?

No. Start with the purchase, refinance or capital requirement you need to solve. We assess the property, income, ownership, existing debt and wider assets first. Where the need spans several properties or other assets, we consider the connected financing options before selecting a product or combination of facilities.

Is there a fee for the initial conversation and buy-to-let assessment?

No. Speaking with a Willow adviser, assessing the investment and presenting appropriate finance solutions are free and carry no obligation. We only charge if you decide to proceed, and we explain all costs before you engage us.

How much deposit is normally needed for buy-to-let?

Deposit requirements vary by lender, property and applicant, but buy-to-let usually requires more equity than a residential mortgage. Pricing and rental stress tests also change at different loan-to-value bands.

What is the buy-to-let rental stress test?

Lenders compare expected rent with a stressed interest payment using an interest cover ratio. The stress rate and required coverage vary by lender, tax position, product and borrowing structure.

Should I buy personally or through a limited company?

That decision has mortgage, tax, legal and administrative consequences. Willow can explain lending differences, but ownership should be agreed with appropriately qualified tax and legal advisers.

Can a first-time landlord obtain a buy-to-let mortgage?

Yes, although lender choice may be narrower. Some lenders also consider whether the applicant owns a residential property, has landlord experience and can support the borrowing outside the rent.

What is a portfolio landlord?

Many lenders treat applicants with four or more mortgaged buy-to-let properties as portfolio landlords. They may assess the whole portfolio, including aggregate leverage, rent, background mortgages and business plans.

Can Willow arrange finance for HMOs and multi-unit blocks?

Yes. These properties may require specialist lenders and additional assessment of planning, licensing, experience, valuation methodology and tenancy arrangements.

Can expats and overseas investors obtain UK buy-to-let finance?

Potentially. Nationality, residence, currency, income, UK credit history, deposit source and ownership structure can all affect lender choice.

Are buy-to-let mortgages regulated by the FCA?

Most business buy-to-let mortgages are not regulated in the same way as residential mortgages. Some consumer buy-to-let arrangements may fall within a different regulatory framework. Willow will explain the position relevant to the transaction.

Speak with a buy-to-let mortgage specialist

Tell us what you want your property borrowing to achieve.

Tell us what you are planning, what makes the financing complicated and when you need it. An outline of the property, rent, ownership, existing borrowing and capital needs is enough to begin. You do not need a product in mind or every document ready.

No fee. No obligation.

Understand your position-finance options before you commit.

Speaking with an adviser, assessing the investment and presenting appropriate solutions costs you nothing. You only pay us if you decide to proceed, after every cost has been explained.
