The case at a glance

The challenge
The clients had recently moved to Australia, had not yet started new jobs and could not rely on rental income alone to satisfy the lender’s stress testing.
The recommendation
Use a specialist lender able to consider top-slicing once Australian employment commenced, alongside five-year fixed, interest-only buy-to-let facilities.
The intended benefit
Retain both UK investment properties, preserve monthly cash flow and keep the portfolio positioned for longer-term growth.
01 / The challenge

Good rental properties. A difficult moment to refinance.

The couple held dual UK and Australian citizenship and had recently relocated permanently to Australia. They wanted to keep two established UK investment properties as part of their long-term property strategy, but both existing fixed-rate mortgages were approaching their end dates.

Their preference was to refinance onto interest-only facilities so that more of the rental income could remain available for cash flow, liquidity and future investment rather than being used to reduce capital immediately.

  • No current Australian employment income The clients expected to return to well-paid professional roles, but they had not yet started new jobs. That meant there was no established overseas employed income to evidence at the point of advice.
  • Rental stress testing created a shortfall Both properties produced good rental income, yet the lender’s affordability calculation indicated that rent alone was unlikely to support the existing borrowing at the required level.
  • Overseas residence narrowed lender choice The combination of recent emigration, future foreign income and UK investment property required a lender comfortable assessing the full cross-border position rather than relying on a standard automated route.

The challenge was therefore not the quality of the properties themselves. It was finding a structure that could bridge the gap between strong underlying assets and an income position that was still in transition.

02 / The recommendation

Build the refinance around future income, rental cover and the right stress test.

Elizabeth identified a specialist lender prepared to consider the applications once the clients had commenced suitable employment in Australia. The lender could then assess surplus personal income alongside the properties’ rent through top-slicing rather than requiring the rental income to carry the full affordability calculation on its own.

  1. Wait for the required employment evidence

    The proposed lender route depended on the clients satisfying its minimum employment requirements after starting new roles in Australia.

  2. Use top-slicing where rent fell short

    Once eligible income could be evidenced, surplus personal earnings could supplement the rental shortfall within the lender’s affordability assessment.

  3. Use five-year fixed, interest-only facilities

    A five-year fixed structure was favoured because the lender’s stress testing was more supportive than on the shorter fixed option, while interest-only aligned with the clients’ cash-flow objective.

The recommendation described here was dependent on the clients commencing employment and satisfying the lender’s full underwriting requirements.

This approach avoided treating the absence of current employment as an automatic reason to abandon the refinance. Instead, it created a route that could become workable once the clients’ new Australian income was established and evidenced in the form required by the lender.

03 / Why this structure

Product choice affected borrowing capacity as well as payment certainty.

Two-year and five-year fixed products were considered. A shorter fix would have created an earlier opportunity to refinance again, but it also produced a more demanding affordability stress test with the lender under consideration. That reduced the borrowing capacity available for the existing loans.

The five-year fixed option therefore offered a stronger fit for this recommendation. It provided a longer period of payment certainty and, crucially, a stress-test treatment that was more compatible with the clients’ required borrowing.

Interest-only borrowing was also consistent with the investment objective because it keeps scheduled monthly payments lower than an equivalent capital-repayment mortgage. The capital balance does not reduce through those payments, however, so the outstanding debt remains due and a credible repayment strategy is essential.

Recommendation status

The strategy identified a lender route that could be pursued once the clients had started suitable employment in Australia and could evidence the income required for top-slicing.

04 / Beyond the mortgage

Protection and estate planning were part of the review.

The clients also wanted each borrower to be able to clear the outstanding mortgage debt if the other died during the mortgage term. Level life insurance was therefore recommended to match the interest-only borrowing, subject to insurer terms and underwriting.

The review also identified that their Wills had not been updated for many years despite the move overseas and continued ownership of UK assets. A separate cross-border estate-planning review was recommended so that the legal position could be considered by an appropriately qualified specialist. Willow’s role in this case was mortgage and protection advice, not legal or tax advice.

05 / Your questions

Understanding an expat buy-to-let refinance.

Can I remortgage a UK buy-to-let after moving overseas?

Potentially. Lender appetite varies according to country of residence, property type, rental coverage, income evidence, loan-to-value and the wider borrower profile. A recent move abroad can narrow the available options.

What is top-slicing in buy-to-let lending?

Top-slicing is an affordability approach where an eligible lender may use surplus personal income to support a rental shortfall. The exact calculation and acceptable income evidence depend on the lender.

Why can a five-year fixed rate help buy-to-let affordability?

Some lenders apply different stress-testing assumptions depending on the product selected. In this case, the five-year fixed option produced a more supportive affordability result than the shorter fixed alternative.

Does interest-only borrowing improve cash flow?

It can reduce scheduled monthly payments compared with an equivalent capital-repayment mortgage, which may help preserve cash flow. The trade-off is that the capital remains outstanding and must be repaid through an acceptable repayment strategy.

Can future overseas employment income be used immediately?

Not automatically. In this case, the proposed route depended on the clients commencing employment and meeting the lender’s evidence and minimum-employment requirements before the income could support affordability.

Your circumstances. Your next step.

Living overseas does not reduce a UK refinance to one affordability calculation.

If you are retaining UK investment property after moving abroad, the right route may depend on how the lender treats your residence, rental income, employment evidence, repayment basis and wider portfolio.

About this case study. Client details have been anonymised. This case describes advice and a proposed lending route; it does not state that the remortgages or protection were completed. Mortgage and insurance availability, criteria and terms depend on individual circumstances and underwriting.

Interest-only mortgages do not repay the capital balance through the monthly payments, so the outstanding capital must be repaid at the end of the term. Rental income can change and refinancing may not always be available on acceptable terms.

As a mortgage is secured against your home or property, it could be repossessed if you do not keep up the mortgage repayments. The Financial Conduct Authority does not regulate some forms of buy-to-let mortgages.
