Becoming a landlord can be a genuinely rewarding way to build long-term income and equity – but it’s not something to walk into lightly. Letting out a property involves real responsibility, ongoing effort, and a solid understanding of the numbers before you commit.
This guide walks through how landlords actually make money, how to judge whether a rental property is a good investment, what you’re legally required to do for your tenants, what rights you hold in return, and some practical tips to help you get off to a strong start.
How Much Money Can You Make as a Landlord?
Your profit as a landlord comes down to how much rent remains once you’ve covered expenses, mortgage repayments, and tax. Rental income is the main driver of profit, but there’s a second source too – if the property rises in value over time, your equity in it grows alongside it.
To work out your likely rental profit, look at your expected income after costs and tax, and check how much rent you’d need to generate to meet a buy-to-let lender’s affordability requirements.
Is Becoming a Landlord a Good Investment?
Two figures are worth understanding before you commit: rental yield and capitalisation rate.
Rental Yield
Rental yield tells you how much annual income a property generates relative to its value. It’s used both to assess mortgage affordability and to judge whether a rental investment is performing well.
Rental yield = annual rental income ÷ property value
A higher yield means you recoup your investment faster. As a benchmark, 10 percent is considered strong, and anywhere from 8 to 12 percent is a healthy range to aim for. Anything significantly above that is worth treating with caution, as it’s not typical.
Capitalisation Rate
Capitalisation rate measures the expected return on a property based on the income it’s likely to generate, and it’s commonly used to gauge how successful an investment property is likely to be.
Capitalisation rate = annual net operating income ÷ current market value
To calculate net operating income:
- Start with total rental income
- Subtract the costs of managing the property
- Subtract mortgage repayments
- Subtract tax owed on the income
- What’s left is your net operating income
As a buyer, a higher capitalisation rate is more attractive, since it points to stronger returns. Sellers tend to prefer a lower rate, as a high one can suggest they’re leaving money on the table – which is why capitalisation rate is also a useful tool for deciding when to sell.
What Are Your Obligations as a Landlord?
Taking on tenants means taking on legal and practical responsibilities toward their safety and wellbeing in your property.
As a landlord, you’re expected to:
- Remain reachable for your tenants, unless a letting agency is managing that relationship for you
- Hold buildings insurance covering risks like fire and flooding, and consider contents insurance too if the property is furnished
- Keep any furniture and appliances you provide in good working order
- Handle or arrange repairs, unless a letting agent is doing this for you
- Make sure the property meets required standards before a tenancy begins, including working smoke alarms and minimum energy performance standards
- Make reasonable adjustments for tenants with additional needs, under the Equality Act 2010
- Protect tenant deposits using a government-approved Tenancy Deposit Protection Scheme, something a letting agent will usually handle
- Keep all required paperwork current, including a gas safety certificate, tenancy agreement, and EPC, and stay aware of upcoming changes to EPC rules
Not everything falls on you, though. Tenants are responsible for:
- Arranging their own contents insurance
- Paying Council Tax
- Covering utility bills, unless you’ve agreed to include these in the rent
What Rights Do You Have as a Landlord?
Being a landlord isn’t only about obligations – you have rights too.
You’re entitled to:
- Receive rent on time, and pursue a legal eviction process if a tenant falls into unresolved arrears
- Increase rent at agreed points during a tenancy, provided the increase is justifiable and in line with local market rates
- Recover reasonable repair costs from tenants where damage is their responsibility
- Expect a tenant to abide by the terms set out in the tenancy agreement
You’re not entitled to:
- Enter the property whenever you choose – tenants must be given at least 24 hours’ notice, even for essential repairs
Practical Tips for New Landlords
1. Get your listing seen online. Most tenants search for rental properties online rather than any other way, and the vast majority use sites like Rightmove or Zoopla, with Rightmove holding the larger share of that traffic. A letting agent who advertises on these platforms gives your property the best chance of being seen quickly – some landlords have had properties let within 48 hours of listing.
2. Invest in good photography. Photos make a real difference to how a listing performs. A professional photographer knows how to use light and angles to show a property at its best, and with most people browsing listings on high-resolution screens, sharp, well-composed images matter more than ever.
3. Consider a featured listing. Paying for a featured spot on a major listings site keeps your property visible at the top of search results and can speed up how quickly you find a tenant, often with room for more photos too.
4. Reference every tenant properly. Before signing anyone, carry out thorough referencing – checking credit history, previous landlords, and current employment. A referencing company can handle this for you. It’s usually paid for by the tenant, though some landlords cover it themselves to make an offer more appealing.
5. Put a proper tenancy agreement in place. This is the legal contract between you and your tenant, and it’s essential for protecting your interests. Templates are available through gov.uk, or a letting agent can draft one for you. Deposits must, by law, be held in a government-approved protection scheme – something a good letting agent will set up alongside a standing order to keep rent payments on schedule.
6. Sort your Energy Performance Certificate. An EPC is a legal requirement before letting, and gives tenants an idea of likely energy costs. You cannot evict a tenant if you never provided one. Since April 2018, buy-to-let properties have generally needed a minimum EPC rating of E, and further changes require a rating of C or above for new tenancies from 2025, extending to existing tenancies by 2028.
7. Keep your gas safety certificate current. A Gas Safe registered engineer must check the property’s gas safety annually, with the renewal carried out within 28 days of the previous check. Working smoke and carbon monoxide alarms are equally important.
8. Think about rent protection insurance. Rent arrears are one of the biggest risks landlords face, and rent protection cover can help ensure your mortgage payments are still met if a tenant falls behind.
Becoming a landlord takes real commitment, but with the right preparation on both the financial and legal side, it can be a solid long-term investment. If you’re weighing up whether a buy-to-let mortgage makes sense for your situation, speaking with a mortgage adviser early on will help you understand what you can borrow and what it will cost.
