Investing in property: opportunities and challenges
Buy to let can be a great way to generate income and build long-term wealth, but arranging the right mortgage is often more complex than a standard residential loan. Deposit requirements are higher, affordability is assessed differently, and lenders all have their own criteria.
Without clear advice, it’s easy to overpay or miss out on products that could improve your return.
Why some landlords pay more than they should
Many investors stay with their current lender out of convenience or apply without understanding how buy to let mortgages are assessed. This can lead to: -
- Paying more interest than necessary
- Being limited to fewer lenders or products
- Struggling to expand a portfolio because criteria aren’t met
- Surprises when rental income alone doesn’t cover affordability checks
The wrong mortgage doesn’t just reduce your profits, it can actually cost you money. Higher rates, unsuitable terms, or tax-inefficient structures can all eat into returns and turn what should be a sound investment into a financial drain. In some cases, making the wrong choice can lead to very expensive long-term mistakes.
That’s why getting expert advice is crucial. An experienced adviser makes sure you avoid these pitfalls and helps structure your mortgage in a way that supports your investment, rather than undermining it.

How I help landlords and investors
I’m Toby Keate, independent adviser at Taylor James Financial Services. I’ve helped many landlords, from first-time investors to experienced portfolio owners, secure the right buy to let mortgage.
Here’s what I do:
- Understand your goals — whether you want rental income, long-term growth, or to build a portfolio.
- Assess borrowing options — looking at deposit levels, rental calculations, and whether topslicing (using personal income to support affordability) might apply.
- Whole-of-market search — exploring a wide range of lenders to find competitive deals that fit your circumstances.
- Explain your choices clearly — whether interest-only or repayment, limited company or personal name.
- Guide you through the process — from application to offer, so your investment plans stay on track.

Key points landlords should know
- Deposit requirements: Most lenders want around 25% deposit, though some will accept 20%. Bigger deposits usually mean better rates, and increased cash flow.
- Affordability checks: Lenders often expect rental income to cover 125%–145% of the mortgage payment.
- Income requirements: Some lenders set a minimum personal income (often around £25,000), while others rely mainly on the property’s rent.
- Property ownership: If you already own property, lenders will check how your existing mortgages are managed.
- Structure options: Mortgages can be taken personally or via a limited company, each has different tax and lending implications.
