10 Expensive Risks to Avoid as a Landlord

Louise Carr 24 August 2026

Being a landlord can be a rewarding investment, but it’s not without its risks. Many of the most costly issues landlords may face can be preventable with the right knowledge, preparation and protection in place.

Gallagher, the NRLA’s Landlords Insurance partner, highlights ten common (and often costly) risks, and how to avoid them.

1. Letting to the Wrong Tenant

Choosing the wrong tenant can lead to:

  • Rent arrears
  • Property damage
  • Costly eviction proceedings

Carrying out thorough referencing - including credit checks, affordability assessments and previous landlord references is essential.

Tip: Don’t rush to fill a void - long-term stability is more valuable than short-term occupancy.

2. Rent Arrears

Missed rent payments can quickly impact cash flow, particularly if you rely on rental income to cover mortgages or other costs.

Even reliable tenants can fall into difficulty unexpectedly.

How to mitigate:

  • Carry out affordability checks
  • Maintain open communication
  • Consider rent guarantee insurance to help protect your income

3. Failing to Keep Up with Legal Requirements

The regulatory landscape for landlords continues to evolve. Missing key obligations such as:

  • Right to Rent checks
  • Deposit protection
  • Gas and electrical safety compliance

can lead to fines, invalidated insurance, or difficulty regaining possession of the property.

Tip: Stay up to date with legislative changes and keep clear records of compliance.

4. Poor Property Maintenance

Delaying repairs can result in:

  • More severe (and expensive) damage
  • Tenant dissatisfaction
  • Increased void periods

Regular inspections and proactive maintenance can save money in the long run and help retain tenants.

5. Inadequate Insurance Cover

Standard landlord insurance may not cover:

  • Rent arrears
  • Legal costs
  • Tenant disputes

Without appropriate cover, landlords can face significant out-of-pocket expenses.

Consider:

  • Legal Expenses Insurance
  • Rent Guarantee Insurance

Reviewing policy terms regularly to ensure suitability

6. Void Periods

Empty properties mean lost income—while costs such as mortgages, insurance and maintenance still need to be paid.

Reduce the risk by:

  • Pricing rent competitively
  • Maintaining the property to a high standard
  • Building strong relationships with existing tenants to encourage renewals

7. Unrealistic Rent Pricing

Setting rent too high can:

  • Deter prospective tenants
  • Extend void periods
  • Increase the likelihood of arrears

While market conditions may justify increases, pricing must remain realistic and sustainable for tenants.

8. Poor Tenant Communication

Breakdowns in communication can escalate small issues into costly disputes.

Tenants expect:

  • Prompt responses
  • Clear communication
  • Professional handling of concerns

Tip: Establish clear communication channels and respond quickly to issues wherever possible.

9. Ignoring Early Warning Signs

Minor issues such as late rent payments or maintenance concerns can be early indicators of bigger problems.

Addressing concerns early can:

  • Prevent escalation
  • Reduce financial impact
  • Improve tenant relationships

10. Costly Legal Disputes

Regaining possession of a property or resolving disputes can be:

  • Time-consuming
  • Complex
  • Expensive

Legal costs can quickly add up, particularly if processes are delayed or challenged.

Mitigation:

  • Ensure full compliance with regulations
  • Keep detailed records
  • Consider legal expenses cover to support you if issues arise
