Being a landlord isn’t just about collecting rent — it’s about protecting your investment, keeping tenants happy, and maximising profits. Unfortunately, many property owners make landlord mistakes that lead to financial loss, legal trouble, and unnecessary stress.

At Legacy Property Sales & Lettings, we work with landlords across Oxfordshire to spot and fix these errors before they become costly. Here are the 5 most common landlord mistakes and how to avoid them.


1. Skipping Tenant Screening

One of the most serious landlord mistakes is placing a tenant without proper checks. This can lead to late rent, property damage, or even eviction.

How to Avoid It:

  • Run credit checks

  • Take landlord and employer references

  • Complete Right to Rent verification

Tip: We use a thorough screening process to find reliable, long-term tenants.


2. Ignoring Routine Maintenance

Neglecting small repairs can cause bigger, costlier problems later.

How to Avoid It:

  • Schedule inspections every 6–12 months

  • Fix minor issues promptly

  • Keep maintenance records for compliance and value


3. Unclear Tenancy Agreements

Vague or incomplete agreements create confusion and increase the risk of disputes.

How to Avoid It:

  • Use a legally compliant Assured Shorthold Tenancy (AST)

  • Clearly outline tenant and landlord responsibilities

  • Include rent due dates, notice periods, and repair terms


4. Not Maximising Tax Reliefs

Missing out on allowable expenses is a common but avoidable landlord mistake.

How to Avoid It:

  • Claim mortgage interest, repairs, insurance, and agent fees

  • Keep organised receipts and records

  • Consult a property tax expert if needed


5. Overlooking Legal Changes

Laws change often — from EPC requirements to fire safety rules — and failing to comply can result in fines.

How to Avoid It:

  • Stay informed via gov.uk or the NRLA

  • Work with a letting agent who keeps you compliant
