A buy to let property can be a great way to generate rental income and build long-term value, but the upfront and ongoing costs can catch new landlords off guard. Before diving into the market, it’s crucial to understand the real financial outlay involved — not just the deposit and mortgage.

Here’s a breakdown of the typical costs you’ll need to budget for when purchasing and managing a buy to let property.

Initial Purchase Costs Buying an investment property comes with several upfront costs, some of which are unique to buy to let purchases:

  • Deposit: Most buy to let mortgages require a deposit of at least 20% to 25%. A larger deposit — say 40% — can help secure better interest rates and broader lender options.
  • Stamp duty: You’ll need to pay a 3% surcharge on top of standard stamp duty rates for additional properties. This can add thousands to your total cost, especially in areas like East Sussex where property values are rising.
  • Legal and valuation fees: These include solicitor fees, property surveys, and lender valuation costs. It’s sensible to budget at least £1,500 to £2,000 for these.

Ongoing Costs of Being a Landlord Beyond the purchase, being a landlord involves a number of recurring expenses. Planning for these helps ensure your investment remains profitable:

  • Mortgage repayments: These may be interest-only or repayment, depending on your lender and financial goals.
  • Letting agent fees: If you hire a letting agent to manage the property, expect to pay 8–15% of your monthly rent in fees.
  • Maintenance and repairs: Boilers break, appliances wear out, and tenants may cause damage. It’s wise to set aside a monthly maintenance fund — often around 10% of the rent.
  • Landlord insurance: This specialist cover protects against property damage, loss of rent, and liability. Costs vary depending on the property and level of cover but typically range from £150 to £300 annually.

Occasional or Unexpected Costs Some costs aren’t regular but can have a big impact if they arise:

  • Void periods: If your property sits empty between tenancies, you’ll need to cover the mortgage and other bills yourself.
  • Compliance costs: These include safety certificates, energy performance upgrades, or changes in licensing laws — all of which can come with short notice.

Final Thought: Plan with Realistic Numbers The most successful landlords are those who budget carefully and plan ahead. It’s not just about whether the rent covers the mortgage — it’s about building a cushion for the unexpected and staying compliant with changing rules.
