What Landlords Need to Know Ahead of the 19 March Rate Decision - Market Outlook, Limited Company Trends & Why Mortgage Brokers Still Beat AI

Published by Charlie Baker of Balanced Financial Services (BFS) & ELA Board member

The spring market is approaching with a palpable sense of anticipation. Until recently, many economists, lenders and market analysts had widely expected the Bank of England to deliver a base rate reduction on 19 March, triggering hopes of improved mortgage affordability for landlords, and we have already seen lenders adjusting deals in anticipation.

However, global uncertainty following the US - Iran conflict has shifted sentiment. Financial markets have become noticeably more cautious, and expectations for interest rate cuts could change rapidly as events unfold.

In this blog, we break down everything landlords need to know:

• What the 19 March rate decision may mean

• How geopolitical tensions might influence mortgage pricing

• Why the market had finally begun to stabilise

• The rapid rise of limited company ownership

• Why a skilled mortgage broker remains essential — even in the age of AI

• Where to find the latest landlord tools and resources via the BFS Buy‑to‑Let Hub

A Widely Expected Rate Cut – But Will It Happen?

For months, markets priced in a spring rate reduction. Inflation had stabilised, swap rates had calmed, and lenders were gradually adjusting fixed‑rate pricing downward.

But interest rate cuts rely on macroeconomic stability, and that stability has been disrupted

How the US–Iran war is influencing financial markets

Geopolitical events move markets quickly. In recent days we’ve seen:

• Increasing oil prices, raising inflationary pressure

• Rising global bond yields, directly influencing UK swap rates

• Central banks reassessing global risk, shifting expectations

If inflation expectations rise again, the Bank of England may take a more hawkish stance on 19 March, or hold again and delay reductions altogether.

What this means for landlords

Even if the base rate doesn’t fall immediately:

• Fixed‑rate pricing may still soften gradually

• Product availability is improving as lenders compete harder

• Innovation has increased, including new entrants to the BTL and SPV markets

• Lenders repeatedly tell us they have appetite to lend

For landlords with fixed products maturing in 2026, even marginal improvements could be valuable.

A Market Finally Stabilising

After the extreme rate volatility of 2022–23, the buy‑to‑let market entered 2024 with:

• More stable pricing patterns

• Reduced week‑to‑week volatility

• Increased product innovation

• More predictable underwriting

• Robust rental demand

This stabilisation has supported better cashflow forecasting and clearer acquisition strategies. But one trend has reshaped the market more than any other: The rise of limited company ownership.

Limited Company Ownership Is Now Becoming “The New Normal”

According to a recent Paragon study, limited company ownership has accelerated dramatically

1. Limited company ownership has surged across the UK

• 680,000 buy‑to‑let properties are now held in limited companies across England and Wales

• The number of BTL companies has quadrupled since 2016

• Over 400,000 BTL limited companies were recorded by February 2025

  
  

2. Most landlords now use SPVs or mixed structures

• Only 23% of landlords now hold properties solely in their personal name

• Two‑thirds have at least one SPV or limited company structure in place

• Younger landlords (25–34 age range) hold 57% of their portfolios in limited companies (Source – Paragon)

3. Taxation changes have driven the shift

The research confirms what many landlords feel acutely:

• Section 24 restrictions remain the single biggest driver, cited by 85% of landlords

• Corporation tax advantages motivate 62% of respondents

• Many incorporate for succession planning or separating business and personal finances

4. Limited company landlords are more growth‑minded

According to Paragon:

• 46% of landlords using limited companies plan to purchase more property versus 29% of individual‑name landlords

• Limited company landlords typically hold larger, higher‑value portfolios (13.7 properties on average versus 4.9)

• Higher profitability is more common among limited company landlords (91%) (Source – Paragon)

5. Incorporation isn’t always the right choice – individual circumstances matter

Considerations include:

• Capital Gains Tax (If moving existing personally owned properties)

• Taxation

• Cost of accountants

• Independent legal advice costs

• Stamp Duty

• Legal restructuring costs

• Slightly more complex product ranges for company lending

Professional guidance is essential.

Why Using a Mortgage Brokers still beat AI

With AI tools becoming increasingly accessible, some landlords (and brokers) are asking whether AI can replace broker advice.

The reality: AI can support — but it cannot replace an experienced mortgage broker.

Here’s why:

1. AI cannot interpret lender nuance

Buy‑to‑let underwriting in some cases is highly complex, especially for SPVs, layered companies, trading companies, HMOs, and multi‑unit blocks. Criteria differences between lenders can make or break a deal as one lenders perfect set up is another lenders policy decline, especially around:

• Minimum income thresholds

• Director/shareholder requirements

• ICR (Interest cover Ratio) calculations and stress tests

• Portfolio‑level exposure limits

AI can summarise published criteria, but it cannot negotiate with a lender, understand grey areas, or anticipate lender appetite.

2. AI cannot provide regulated mortgage advice

Only regulated professionals can:

• Recommend the most suitable product

• Assess long‑term financial implications

• Provide suitability letters

AI cannot take responsibility for the advice it gives. A broker can. Its important to note that most buy‑to‑let mortgages are not regulated — but brokers still assess suitability, risk, lender fit, and alignment with portfolio goals.

AI cannot take responsibility for its output

3. AI can't fight your case or decline

Good Brokers wont just accept lender declines - We are here to fight your corner. We:

• Challenge down valuations with comparable evidence or challenge inaccuracies

• Query incorrect underwriter decisions (It actually does happen)

• Provide additional reassurance to underwriting teams

• Address misunderstandings directly with lenders

• Seek reinstatement where possible

AI cannot speak to a lender or advocate on your behalf.

Why This Matters: Decline Data

AI‑generated estimates suggest that in the UK mortgage market (accuracy not guaranteed because its AI generated):

• DIP acceptance: 86%

• Application to completion: 65%

• Fallout: 35%

BFS Performance (Real Data, April 2024–April 2025)

83% of BFS‑submitted cases completed successfully.

A good broker significantly increases your chances of success

See the BFS - WHY USE A BROKER page where we go through in detail the reasons why using a mortgage broker could be very much worth your while: https://www.balancedfinancialservices.co.uk/why-use-a-broker

We also share insights on how to choose a broker - Of course we would like you to work with Balanced, but we don't suit everyone and sometimes we don't have capacity, so we also published our insiders guide on how to choose a broker https://www.balancedfinancialservices.co.uk/how-to-get-the-right-mortgage-broker

4. Real‑world market experience still wins

Brokers see daily what AI cannot:

• Which lenders have queue times

• Which lenders are tightening or loosening criteria

• What the chances of valuation or decline appeals are

• How lenders view non‑standard cases

• Which underwriters are accommodating unusual structures

This market information is invaluable in increasing the likelihood of a successful application resulting in a formal mortgage offer.

4. Human brokers build long‑term strategy & relationships

At BFS, we don’t simply source today’s cheapest rate - there are plenty of comparison sites that do that (although not all lenders will show on these sites). We:

• Consider longer term rate risk

• Assess your short & long term portfolio plans

• Help you problem solve and create a plan to get you to your objectives

• Help you plan purchases, reviewing properties for potential lender issues before you buy

• Recommend lenders who will support your own buy to let business plans

• Build refinance strategies years in advance ensuring that you are in a good place for portfolio growth

AI cannot replicate this strategic service.
