Buy-to-Let Mortgages

First-time landlord guide

Legal obligations, insurance, tenant management, and common mistakes to avoid as a new landlord.

4 min readWritten by Ersan Hassan

Becoming a landlord for the first time is exciting, but there’s more to it than buying a property and finding a tenant. This guide covers everything a new landlord needs to know — from getting the right mortgage to understanding your legal responsibilities.

Can you get a buy-to-let mortgage as a first-time buyer?

Some lenders do offer buy-to-let mortgages to applicants who don’t already own a residential property, but options are more limited. Most mainstream BTL lenders require you to own (or be buying) your own home first.

If you’re a first-time buyer looking to go straight into buy-to-let, expect to need a larger deposit (often 25–30%), strong rental income projections, and evidence that you can afford both the BTL mortgage and your own housing costs.

Some lenders do offer buy-to-let mortgages to applicants who don’t already own a residential property, but your options will be more limited. Most mainstream BTL lenders require you to own (or be buying) your own home.

First-time buyer stamp duty

If you’re buying a BTL as your first ever property purchase, you won’t qualify for first-time buyer stamp duty relief — and you’ll pay the additional property surcharge (currently 5%). This is a significant extra cost to factor into your budget.

What costs should you budget for beyond the mortgage?

New landlords often underestimate the ongoing costs of property investment. Your mortgage payment is just the starting point.

Typical annual landlord costs

£300–£500
Landlord insurance
Buildings, contents, and liability cover
8–12%
Letting agent fees
Percentage of monthly rent for full management
1–2 months
Void periods
Budget for empty periods between tenants
£1,000–£2,000+
Maintenance & repairs
Boiler servicing, plumbing, decorating between tenancies

A good rule of thumb is to set aside 20–30% of rental income for ongoing costs, maintenance, and void periods. This ensures you’re not caught out when the boiler breaks or a tenant moves out unexpectedly.

How do you choose the right investment property?

The right property depends on your goals. Are you looking for steady rental income, long-term capital growth, or both? Location, property type, and tenant demand all play a role.

Research rental yields in different areas. Yield is calculated as the annual rent divided by the property’s value, expressed as a percentage. A 5–7% gross yield is generally considered good for a buy-to-let, though this varies by region.

Consider the type of tenant you want to attract. A two-bed flat near a university will suit students or young professionals; a three-bed semi near schools will attract families on longer tenancies. Each has different management requirements and turnover rates.

Setting up your tenancy properly

Getting the paperwork right from the start protects both you and your tenant.

  1. 01

    Use an assured shorthold tenancy (AST)

    The standard tenancy agreement in England and Wales. It gives both parties clear rights and obligations. Use a professionally drafted template or instruct a solicitor.

  2. 02

    Conduct thorough referencing

    Credit checks, employer references, and previous landlord references help you choose reliable tenants. Many letting agents offer referencing services.

  3. 03

    Create a detailed inventory

    Document the condition of the property with photos and descriptions before the tenant moves in. This protects you if there are disputes about the deposit at the end of the tenancy.

  4. 04

    Protect the deposit

    Register the deposit with a government-approved scheme (DPS, MyDeposits, or TDS) within 30 days and provide the prescribed information to the tenant.

  5. 05

    Provide required documents

    Give the tenant a copy of the EPC, gas safety certificate, the government’s How to Rent guide, and the deposit protection certificate before or at the start of the tenancy.

Common mistakes new landlords make

Learning from other landlords’ mistakes can save you time, money, and stress.

Underestimating costs

  • Not budgeting for void periods, maintenance, and tax
  • Forgetting about stamp duty surcharge and legal fees upfront
  • Relying on 100% occupancy to cover the mortgage

Skipping legal requirements

  • Not protecting deposits or providing prescribed information
  • Missing gas safety or electrical certificates
  • Using DIY tenancy agreements that don’t comply with current law

Inadequate insurance

  • Standard home insurance doesn’t cover rental properties
  • You need specialist landlord insurance including buildings, contents, and liability
  • Consider rent guarantee insurance if you’re relying on rental income

Emotional decisions

  • Buying a property you’d want to live in rather than what tenants want
  • Over-investing in finishes that don’t increase rent or value
  • Not treating the investment as a business
