Why become a landlord?

Becoming a landlord might appeal to anyone with a spare room, access to additional properties, or someone looking to expand their existing property portfolio. It’s a common way to earn extra income, either as a supplementary source, or as a full-time occupation for some.  

Growth of the private rental sector

Up until the 1980s, the private rental sector was in steady decline. The introduction of the Right to Buy scheme allowed council tenants to purchase council homes from local authorities, with little new housing built to replace them.

As a result, traditional social housing decreased by 1.4 million over the next few decades, and private rentals grew to dominate the UK rental market. Between 2000 and 2022, private renting tripled.

Challenges in today's market

As the private rental market has grown, landlords today face new challenges. Factors like global events and domestic politics can affect interest and mortgage rates, leading to higher costs for both homeowners and landlords.

Tax changes in the UK, such as the reduction of mortgage interest tax relief, have also placed additional financial strain on landlords, making it harder to offset costs.

While some landlords have been forced to sell up their properties, others have passed on the cost to tenants. In April 2024, rents increased by almost 9% year on year – the highest ever recorded.  

Getting started

There’s a lot more to becoming a landlord than simply collecting rent. There’s legislation, responsibility, expenses and costs at play too.

What’s more, simply converting mortgage costs into higher rent isn’t always a viable option – as your tenants may not be able to afford it. How and when landlords increase rent could also be subject to future Government policy.

Let’s go through the considerations you need to take step by step.

Choosing the right property

The first step to becoming a landlord is finding the right property. You may have a house already that you want to rent out, or perhaps you have the cash available to invest in a new property.

Either way, there are a few factors to consider before your tenants can sign on the dotted line.

Financial considerations as a landlord

While being a landlord can bring money in, it also comes with a range of associated costs. Like any business, there are a variety of incomings and outgoings that you’ll need to manage and prioritise accordingly. These include:

1. Choosing a buy to let mortgage

2. Paying tax

3. Setting rent

4. Landlord expenses and fees

5. Understanding rental yield

1. Choosing a buy to let mortgage

buy to let mortgage is for people looking to buy a property with the intent of renting it out. It has borrowing limits and the deposit requirements are different from regular residential mortgages. Some also often offer longer loan terms.

With NatWest, you'll need to have at least 25% of the property purchase price as a deposit. We offer both interest-only and capital and interest mortgage options, with terms of up to 35 years, depending on your eligibility.

 

2. Paying tax

Other outgoings you’ll have to consider when becoming a landlord are taxes and further property fees. As you’ll be self-employed, it’s important that you fully understand what needs paying, how much and when.

3. Setting rent

When deciding what rent to charge, consider the research you carried out when choosing your property.

Compare local prices, considering factors like location, size, condition, and amenities. Aim for a fair price that covers your costs while staying competitive.

4. Landlord expenses and fees

Besides considering the bigger picture numbers – like tax, for example, there are smaller costs to consider when becoming a landlord.

5. Understanding rental yield

Rental yield is a calculation of how much you can expect to make on your buy to let property or properties.

It’s important to calculate so you can work out how much you’re expecting to earn against your expected outgoings.

It can give you a valuable insight into whether certain properties are likely to be profitable, and where you might need to consider making changes.

Finding tenants for your rental property

You’ll need to consider the type of tenants you want in your property, and how you might go about attracting them. 

 

  • Families: Is it a larger property with multiple bedrooms and child-friendly amenities close by? Think schools, parks and recreational facilities.

 

  • Couples and working professionals: Two-bed city-centre apartments are often prime for these types of tenants. They’re looking for good travel links and direct access to local amenities.

 

  • Students and groups: You may want to focus on renting to students and groups if your property has multiple rooms, large facilities and is in a prime university location.

 

You’ll then need to decide how you want to find these tenants and advertise your properties. Generally, you have two options when looking to do this.

Arranging privately

There are a number of ways you can advertise your homes and find the right tenants independently. For example, by uploading listings to online property sites, where potential renters can filter by their preferences.

You could also turn to social media, with some platforms like Facebook Marketplace offering another way to advertise rental properties.

Using an agency

Letting agencies – and individual agents – can also help you advertise and find the right renters, but keep in mind that this will come at a cost. They are especially useful if you own multiple properties, as the admin can be a lot to keep on top of.

You can approach online letting agents, who will upload your properties to both their and third-party sites. There are also street letting agents, who actively showcase properties in high street branches.

Responsibilities of a landlord

When you become a landlord, your main responsibility will be to provide a safe and pleasant environment in which your tenants can live or work.

The safety and wellbeing of the occupiers of your properties should be your number one priority. As a start, you should make sure that:

  • your properties do not present any health hazards (such as mould and asbestos)
  • you have all the relevant electrical, fire and gas safety certificates
  • all electrical and gas equipment is installed and maintained correctly
  • your properties have all the correct fire and carbon monoxide alarms fitted
  • your tenants’ deposits are protected by an official Government protection scheme
  • you provide your tenant with all the necessary renting information (for example, a How to Rent checklist)
  • you undertake all the necessary health and safety inspections, as regulated by the Housing Health and Safety Regulating System (HHSRS).

Managing your rental property

Similar to advertising your property and finding your tenants, you can choose to manage your property as an individual landlord or hire an agency.

The latter helps manage your properties on your behalf and acts as an intermediary between you and your tenants.

Depending on the type of agent you pay for, they can help manage:

  • setting and collecting rent
  • managing tenant references and credit checks
  • contracts and tenancy agreements
  • general property management and maintenance
  • property inspections
  • moving tenants in.

If you have multiple properties, hiring a letting agent might be a good idea. It can help free up your time so you can focus on managing your business.

Letting agents are also incredibly experienced so, if you’re new to becoming a landlord, they can provide a valuable helping hand.

Tips for being a good landlord

A good tenant-landlord relationship is key to the longevity and profitability of your rental. Building a rapport with people can help encourage long-term tenancies, with renters you trust.

 

With this in mind, there are a number of ways you can stay proactive in maintaining these relationships.

Be responsive and reliable

Your tenants are your first priority. Show this by responding to any issues as soon as you’re able.

Being a reliable landlord means providing effective tenant care and efficient solutions in a timely manner.

Fix, repair and maintain

As the owner of the property, it’s your responsibility to maintain it. Accidents happen, as do general wear-and-tear and equipment malfunctions.

At the end of the day, your property is the tenant’s home. Care for it like you'd care for your own home.

Be flexible and understanding

Sometimes unforeseen circumstances can arise, such as missed rent payments or accidental damage to your property.

If this happens, renters might briefly rely on you to be flexible and understanding.
