Why outdated assumptions can reduce your borrowing power or derail your plans in today’s market.

The mortgage market has changed dramatically over the past few years. Interest rate movements, affordability recalculations, updated underwriting models, and shifting lender attitudes have transformed how applications are assessed. Yet despite these changes, many homeowners continue to base their decisions on myths—ideas that may have been true once, or perhaps never true at all, but persist through hearsay and old advice.


These misconceptions often cause people to delay moving, avoid remortgaging, or underestimate the options available to them. In our work at Willow Private Finance, we regularly encounter clients who believe they won’t qualify for a mortgage anymore, or that switching lenders is too difficult, or that their age, income structure, or past credit events automatically exclude them. In reality, the mortgage market offers far more flexibility, creativity, and lender diversity than most homeowners realise.


This article cuts through the noise and explains which myths to ignore when considering a home move or remortgage. For additional detail on related themes, you may find value in our articles on how underwriting has changed and five strategic reasons to remortgage this year beyond rate drops.


Market Context: Why Myths Persist


The financial headlines of recent years have contributed to widespread confusion. Interest rate volatility, tighter affordability models, and high-profile lender withdrawals have led many homeowners to assume the worst about their borrowing prospects. Furthermore, older guidance—some dating back to the pre-2014 Mortgage Market Review era—still circulates widely.


The reality is far more nuanced. Competition among lenders remains strong, private banks continue to expand their UK mortgage offering, and specialist lenders have become increasingly sophisticated. Underwriting remains detailed, but it is often more individualised and adaptable than borrowers expect.


At the same time, digital tools, automated affordability checks, and enhanced income modelling mean lenders can analyse cases more intelligently. These changes mean many long-held assumptions no longer apply, yet homeowners continue to make decisions based on outdated information.


Myth 1: “You Can’t Move Home or Remortgage After Rates Rise”


One of the most common myths is that once interest rates increase, homeowners should avoid moving or remortgaging altogether. This belief stems from the assumption that all new rates will inevitably be unaffordable or that existing lenders will not offer competitive terms.


While it is true that rates remain higher than historic lows, the market has stabilised significantly. Many lenders have repriced downward, competition between banks has increased, and affordability models have evolved. More importantly, mortgage strategy is not only about interest rates. It is also about:


  • leveraging equity
  • improving cash flow
  • consolidating debt
  • releasing capital for investment or renovation
  • restructuring repayment terms to suit long-term planning


We frequently support clients who initially feared moving or remortgaging, only to achieve a stronger financial position after restructuring their mortgage—whether through a strategic product switch, term extension, or interest-only arrangement aligned with long-term plans. .


Myth 2: “Your Age Automatically Limits Your Borrowing Power”


Age is often misunderstood in mortgages. Many borrowers believe that once they reach their 50s or 60s, lenders will restrict terms drastically or decline applications. In reality, term and age limits vary significantly between lenders, and private banks take an entirely different approach from mainstream institutions.


Borrowers with strong wealth profiles—such as pensions, investments, company shares, or property portfolios—often qualify for mortgage terms well beyond what they assumed was possible. Even high-street lenders frequently lend to age 70, 75, or 80, depending on income type and retirement planning.


The key determinant is not age itself, but the clarity of the long-term repayment strategy. Borrowers who can demonstrate pension income, investment income, business owner exit strategy, or asset-backed repayment often find they have far more options than expected.


Myth 3: “You Must Stay With Your Current Lender”


Product transfers are highly convenient and often attractive—but they are not always the best route. Many homeowners assume that switching lenders (a remortgage) is too complex or risky, or that new affordability assessments will prevent them from qualifying elsewhere.

In reality, remortgaging can offer significant advantages:


  • more competitive rates
  • interest-only or part-and-part structures
  • higher loan amounts
  • more favourable overpayment terms
  • capital raising for investment or renovation


For property owners looking to release funds—for example, to support children onto the property ladder, renovate their home, or boost an investment portfolio—switching lenders is often the most effective strategy.


Even borrowers with complex income patterns, international earnings, or self-employment find that whole-of-market lenders—including private banks—can offer tailored solutions far beyond what their current lender provides.


Myth 4: “Variable Income Makes Borrowing Impossible”


This myth is particularly persistent among self-employed individuals, company directors, consultants, entrepreneurs, and those paid through commission or bonuses. Many assume lenders will disregard variable income or treat it too conservatively to be useful.


While some high-street lenders do apply weighted averages or restrict certain income types, the broader market—including private banks—takes a much more holistic view. Bonus income, carried interest, dividends, director’s remuneration, profit share, international earnings, and investment income can all be considered with the right lender.


Furthermore, specialist lenders often focus on the forward-looking strength of a business or earnings trajectory rather than Just historical averages.


Borrowers with complex income often achieve significantly higher borrowing power by selecting a lender that understands their specific income structure—a service Willow Private Finance provides throughout the UK and internationally.


Myth 5: “Bad Credit in the Past Means You Can’t Remortgage or Move”


Many homeowners assume that historic credit issues—such as late payments, old defaults, or past arrangements—automatically disqualify them from mainstream lending. This is rarely true.


Lenders differentiate between:


  • one-off events
  • systemic issues
  • recency and severity
  • financial behaviour since the event


Underwriting is more nuanced than it was a decade ago. Borrowers with older credit events, or those who have since demonstrated strong financial conduct, often qualify for prime products. Even where specialist lenders are required, competitive rates remain accessible.


What matters most is early assessment. Clients who come to Willow Private Finance before applying are able to structure their case properly, avoid unnecessary declines, and target the lenders most likely to approve.


Myth 6: “You Can’t Move Home Until You Sell Your Current One”


This misconception prevents many people from securing their ideal property. In reality, homeowners have a range of options that allow them to move before selling, including:


  • regulated bridging finance
  • equity release from their existing property
  • private bank credit lines
  • short-term interest-only arrangements
  • let-to-buy structures


Buying before selling is increasingly common due to fragile chains and fast-moving markets. While the temporary second home Stamp Duty surcharge is a consideration, it can be reclaimed once the sale completes within 36 months.



Myth 7: “Interest-Only Mortgages Are Only for High-Net-Worth Borrowers”


Interest-only mortgages were once associated primarily with high-value lending and private banks. Today, they are widely available across the market—including mainstream lenders—for borrowers who meet certain criteria.


Interest-only can be highly effective for:


  • reducing monthly payments
  • managing cash flow
  • supporting retirement planning
  • aligning repayment with expected future assets (e.g., pensions, bonuses, equity sales)


The key is the repayment strategy. Borrowers with clear long-term plans often find interest-only an ideal structure, especially when paired with part-and-part arrangements.


What Happens When Myths Go Unchallenged


At Willow Private Finance, many of our most successful cases begin with clients who believed they had no options. Some thought their age prevented borrowing; others were convinced their variable income would be ignored; others avoided remortgaging for years due to fear of affordability checks.


Once their full financial profile is understood, these barriers often disappear. Clients secure higher borrowing, lower payments, improved loan structures, or access to private banking solutions they did not know existed.


The biggest risk homeowners face is not high rates or strict underwriting—but making decisions based on outdated or incorrect assumptions.

Frequently Asked Questions


Why have I been approved for a mortgage, but not for the amount I need?
This is known as an affordability shortfall. The lender is satisfied that you meet its basic lending criteria but has capped the maximum loan based on its affordability model. This often reflects stress testing, income treatment or expenditure assumptions rather than your actual ability to repay the mortgage.


What is an affordability shortfall?
An affordability shortfall occurs when a lender offers you a mortgage that is lower than the amount you need to complete your purchase or refinance. Rather than declining your application outright, the lender limits the loan size based on its own affordability calculations.


Why are affordability shortfalls more common?
Lenders continue to apply conservative affordability assessments, often stress testing mortgages at interest rates significantly higher than the actual product rate. Many also use standardised household expenditure models and apply stricter rules to variable, self-employed and overseas income than in previous years.


Can I borrow more by applying with a different lender?
Yes. Different lenders assess affordability in very different ways. Some are more flexible with bonuses, dividends, foreign income, retained profits, pensions or investment income. A borrower who falls short with one lender may qualify for the full borrowing requirement with another.


Do self-employed borrowers experience affordability shortfalls more often?
Frequently, yes. Many mainstream lenders average profits over several years, ignore retained company profits or place restrictions on dividend income. Specialist lenders can often assess self-employed income more holistically, depending on the circumstances.


Can high earners still fail affordability assessments?
Absolutely. High income alone does not guarantee maximum borrowing. If a significant proportion of earnings comes from bonuses, commission, carried interest, dividends or overseas income, some lenders may only recognise part of that income when calculating affordability.


Should I reduce my purchase price if I have an affordability shortfall?
Not necessarily. While reducing your budget is one option, it is often worth exploring alternative lenders or different mortgage structures first. A specialist broker may be able to identify lenders whose affordability models are better suited to your financial profile, allowing you to proceed without compromising on the property.


Can interest-only or longer mortgage terms help improve affordability?
Yes. In appropriate circumstances, longer mortgage terms, part interest-only structures or full interest-only mortgages supported by a credible repayment strategy can improve affordability. These options must be suitable for your circumstances and accepted by the lender.


Can asset-rich borrowers qualify even if their taxable income is relatively low?
Yes. Some private banks and specialist lenders assess a borrower's overall wealth, investment portfolio and liquidity rather than relying solely on earned income. This approach can be particularly beneficial for entrepreneurs, investors, retirees and family offices.


How can a specialist mortgage broker help overcome an affordability shortfall?
A specialist broker will assess why the affordability gap exists, identify lenders with more suitable underwriting criteria, restructure the application where appropriate and present your income in the strongest possible way. In many cases, this can bridge the affordability gap without requiring a larger deposit or a lower purchase price.
