What Are the Requirements for Landlords Applying for a Rental Property Mortgage in Scotland or London?

If you’re asking what are the requirements for landlords applying for a rental property mortgage in Scotland or London, you’re already ahead of many investors.

‍

Buy-to-let mortgages are not approved using simple checklists. They are approved based on lender-specific rules that vary by location, property type, ownership structure, and risk profile.

‍

This guide explains those requirements clearly, without jargon or generic advice.

‍

The Core Reality of Buy to Let Mortgage Requirements

‍

For landlords, lenders focus less on personal affordability and more on risk.

Risk is assessed through:

• The property itself
• The expected rental income
• The loan structure
• Your experience and financial stability

‍

This is why two landlords with identical deposits can receive very different outcomes.

‍

Minimum Deposit Requirements for Landlords

‍

Across Scotland and London, most lenders require:

‍

25% minimum deposit (75% LTV)

‍

Some lenders require 30% to 35% deposits for:

• Flats above commercial units
• Short-term lets
• First-time landlords
• Limited company purchases

‍

A larger deposit:

• Expands lender choice
• Makes stress testing easier
• Improves long-term flexibility

‍

This often matters more than chasing the lowest headline rate.

‍

Rental Income Requirements: The Biggest Deal Breaker

‍

Rental stress testing is the most common reason buy-to-let applications fail.

Lenders apply an Interest Coverage Ratio (ICR), meaning rent must exceed the mortgage payment by a set margin.

‍

Typical rules include:

• 125% ICR for basic-rate taxpayers
• 145% ICR for higher-rate taxpayers
• Stress testing at a notional interest rate

‍

Example:

If the stressed mortgage payment is £1,000 per month, required rent could be £1,250 to £1,450 per month.

This particularly affects buy to let affordability in London, where yields are often tighter.

‍

Scotland vs London: How Requirements Differ

‍

Scotland Buy to Let Requirements

‍

In Scotland, lenders consider:

• Home Report valuation
• Local authority rental demand
• Property construction type
• Short-term let restrictions

‍

Key nuance:

If the purchase price exceeds the Home Report valuation, lenders base lending on the lower valuation, not the price paid.

‍

This affects:

• Deposit size
• Rental stress testing
• Maximum borrowing

‍

This is critical for landlords buying in Glasgow, Edinburgh, and Ayrshire.

‍

London Buy to Let Requirements

‍

In London, lenders focus heavily on:

• Rental yield relative to property value
• Market volatility
• Portfolio exposure
• Personal income as back-up

‍

Even experienced landlords can be restricted if:

• Yields are low
• Stress tests fail
• Too much borrowing sits with one lender

‍

This is why buy to let lender selection in London is crucial.

‍

Does Landlord Experience Matter?

‍

Yes, but not always how investors expect.

‍

Lender categories include:

• First-time landlords – fewer lenders, higher deposits
• Experienced landlords – more flexibility
• Portfolio landlords (four or more properties) – additional scrutiny

‍

Portfolio landlords are often required to provide:

• Property schedules
• Rental income breakdowns
• Mortgage balances
• Portfolio stress tests

‍

Preparation matters more than income alone.

‍

Personal Income Requirements

‍

Although buy-to-let lending is rental-led, lenders still check:

• Personal income
• Employment stability
• Credit profile

Some lenders require:

‍

£25,000 minimum personal income

‍

Others waive this if rental coverage is strong.

Certain lenders allow top-slicing, using personal income to support rental shortfalls, but only with the correct structure.

‍

Limited Company Buy to Let Requirements

‍

Limited company buy-to-let (SPV) purchases are increasingly common.

Typical requirements include:

• Company set up solely for property
• Directors acting as personal guarantors
• Deposits of 25% to 30%
• Slightly higher fees in some cases

‍

Lenders assess:

• Director experience
• Company structure
• Future portfolio plans

‍

Comparison sites rarely explain these details.

This is where specialist limited company buy to let advice becomes essential.

‍

Property Types That Trigger Stricter Criteria

‍

Some properties face tougher lending rules:

• Flats above shops
• High-rise buildings
• Studio apartments
• New-build properties
• Short-term let or Airbnb use

‍

Even with strong finances, the wrong property can result in a decline.

‍

Credit History Requirements

‍

Lenders review:

• Missed payments
• Defaults
• CCJs
• Credit utilisation

‍

Minor historical issues may be acceptable.

Recent or unresolved issues can restrict lender choice.

The key is not perfect credit, but matching the right lender to the profile.

‍

Why Many Landlords Fail Without Advice

‍

Common mistakes include:

• Applying directly to one lender
• Assuming all lenders assess rent the same way
• Ignoring Scottish Home Report rules
• Structuring portfolios without foresight
• Focusing only on rates, not criteria

These mistakes can lead to:

• Declines
• Lost valuation fees
• Delays
• Reduced future borrowing power
