The #1 Mistake Landlords Make & How to Avoid It

09 December 2025.Long Lets

Let’s be honest: being a landlord isn’t always as simple as it sounds. Between tenants, maintenance, and ever-changing laws, things can get complicated fast. But most of the problems landlords run into come from one main issue:

They don’t treat their rental property like a business.

It’s an easy mistake to make - especially if you’re renting out a home you used to live in or you only have one property. But when decisions are made on instinct rather than process, problems tend to follow.

Here’s what happens when landlords slip into “casual mode":

1. Choosing the wrong tenant

Relying on a “good feeling” instead of proper referencing can lead to:

  • Late rent
  • Damage
  • Disputes
  • Stress

One solid referencing check can save months of hassle.

2. Falling behind on legal responsibilities

Landlord rules and regulations change often, especially now more than ever with the Renters Rights Bill coming into effect. Missing deposit protection deadlines, safety certificates, or the right paperwork can lead to fines - sometimes big ones!

3. Losing money without realising it

When you’re not running things like a business, it’s easy to miss:

  • Small maintenance issues
  • Tax allowances
  • Rent pricing changes
  • Ways to reduce void periods

All of these affect your bottom line.

4. Stress - lots of it

Without systems in place, everything becomes a last-minute fire to put out. A simple checklist or process can make managing a property feel a lot lighter.

How to Avoid the Mistake (Without Making Life Complicated)

Good news: treating your property like a business doesn’t mean becoming a corporate machine. It just means being organised and consistent.

Here’s how:

Use proper tenant referencing

Credit checks, income verification, and previous landlord references are essential.

Stay compliant

Keep up with safety certificates, deposit rules, and licensing.

Create simple processes

Things like:

  • How you handle repairs
  • How often you do inspections
  • How tenants report issues

 

These save time and avoid confusion.

Keep good records

Emails, receipts, inspection notes - everything should be easy to find when you need it.

Consider using a letting agent

Treating your rental like a simple, well-organised business is the key to avoiding stress and protecting your investment. And while you can manage it alone, you don’t have to.
The right agent will handle compliance, tenant checks, inspections, and day-to-day issues, making the whole experience much more hands-off.
