Expert Guidance for Property Investors

Buying a rental property or expanding your portfolio can be highly rewarding — but buy-to-let mortgages come with specific rules, criteria, and risks. At Middleton Finance, I provide clear, expert guidance to help you make informed decisions, avoid costly mistakes, and structure your mortgage correctly from the outset.

Buy-to-Let Advice Tailored to Your Investment

No two property investors are the same. Whether you’re purchasing your first rental property or expanding an established portfolio, I tailor advice to your circumstances and long-term plans.

I regularly support landlords with:
• First-time buy-to-let purchases
• Remortgaging existing rental properties
• Portfolio landlord lending and expansion
• Interest-only vs repayment options
• Limited company vs personal ownership

UK Buy-to-Let Mortgage Requirements

Most buy-to-let lenders assess applications based on:

  • Deposit: Typically 25% of the property value
  • Rental income: Usually required to cover 125–145% of mortgage payments
  • Credit history: A satisfactory record with no recent serious issues


Some lenders also support first-time landlords or applicants with limited experience. I assess your position carefully and match you with lenders most likely to approve your application.

Portfolios, Limited Companies, and Tax Considerations

  • Many investors now purchase through a limited company, which can affect mortgage criteria, rates, and tax treatment
    • Portfolio lending rules can impact how many properties you can finance with certain lenders
    • Mortgage interest and rental income tax rules can significantly affect returns

Where appropriate, I work alongside accountants to ensure your mortgage structure supports your wider financial position.
