We analyse rental yields, tenant demand, and tax changes affecting Sussex landlords to help you make an informed decision. In this comprehensive guide our Sussex mortgage advisers break down everything you need to know.
Sussex Property Market Context
The Sussex property market in 2026 presents both challenges and opportunities. Average prices range from £320,000 in Crawley to £480,000 in Horsham, with the coastal cities of Brighton (£420,000) and Hove (£460,000) reflecting their desirability and London commuter demand. Understanding these local dynamics is essential to making the right mortgage decision.
Crawley (average £320,000) — Post-war new town housing with distinct neighbourhood identities. Fast london commuting via three bridges and gatwick airport employment. Offers 25–30% savings over Horsham and 40%+ over Brighton. Three Bridges properties command a premium for the 30-minute London Bridge service. Buy-to-let demand is strong from airport and tech corridor workers.
Worthing (average £350,000) — Victorian terraces, inter-war suburbs and regenerating seafront developments. Genuine value compared to brighton with improving amenities. Prices are 15–20% below Brighton equivalents, attracting priced-out coastal buyers. First-time buyer opportunities exist under £250,000 for flats. Buy-to-let yields of 5.5–6.5% outperform Brighton.
Brighton (average £420,000) — Regency terraces, modern seafront apartments and suburban family homes. Fast trains to london victoria in under an hour. First-time buyers face deposits of £60,000+ at 15% LTV. The rental yield of 5–6% supports buy-to-let demand. Conservation areas around The Lanes and Kemptown add purchase complexity requiring specialist lender knowledge.
Hove (average £460,000) — Grand victorian and edwardian architecture with wide tree-lined avenues. A quieter alternative to brighton with premium prices. Consistently commands a 5–10% premium over equivalent Brighton properties. Family homes with four-plus bedrooms in the Hove Park area regularly exceed £700,000.
Sussex Buy-to-Let Market Analysis
Sussex offers a compelling buy-to-let proposition driven by London commuter demand, two universities, Gatwick Airport employment and a strong domestic rental market. However, tax changes since 2017 mean that investment structure and mortgage product selection matter more than ever.
Rental Yields by Sussex Area
Brighton (5–6% gross yield) — Student lets near the universities achieve the highest yields. Professional lets in Kemptown and the city centre are strong. HMO opportunities in terraced streets off Lewes Road. High entry prices but consistent demand.
Worthing (5.5–6.5% gross yield) — Better yields than Brighton on lower entry prices. Growing demand from Brighton commuters and the town’s own economic regeneration. New-build flats in the town centre and period properties in Broadwater both let well.
Crawley (5.5–7% gross yield) — The highest yields in Sussex, driven by airport worker demand and affordable entry prices. Properties near Three Bridges station and in Broadfield offer the best returns. Strong demand from airline and logistics sector tenants who need proximity to Gatwick.
Horsham (4–5% gross yield) — Lower yields but stronger capital growth prospects. Premium tenant profile — families and professionals. Longer average tenancies mean lower void periods and management costs. Less volatile than student or short-let markets.
Tax Considerations for Sussex Landlords
Section 24 mortgage interest relief restriction means higher-rate taxpayers can no longer deduct mortgage interest from rental income before tax. Instead you receive a 20% tax credit. For a Sussex landlord with £1,500 monthly rent and £800 mortgage interest, the effective tax rate has increased significantly. This makes limited company structures worth considering for new purchases.
The 3% stamp duty surcharge on additional properties adds to acquisition costs. On a £300,000 Crawley buy-to-let, stamp duty is £14,000 rather than £5,000 for a residential purchase. Capital gains tax on disposal is 18% for basic rate and 28% for higher rate taxpayers. We factor all of these into our mortgage advice to ensure the numbers work for your specific situation.
Limited Company BTL in Sussex
Purchasing through a Special Purpose Vehicle (SPV) limited company allows full mortgage interest deduction against profits. Corporation tax at 25% may be lower than your personal marginal rate. Retained profits can fund future purchases without personal tax. However, limited company BTL mortgages typically carry higher rates (0.5–1% above personal BTL rates) and some lenders restrict them. We compare the full financial picture including tax savings versus higher mortgage costs to determine which structure is best for you.
Why Professional Mortgage Advice Matters
The difference between the right and wrong mortgage can be tens of thousands of pounds over the term. A 0.5% rate difference on a £350,000 mortgage amounts to over £25,000 across 25 years. Even a £100 per month saving adds up to £30,000 over the life of a typical mortgage. That is why professional whole-of-market advice — which costs you nothing — is one of the smartest financial decisions you can make.
A bank can only offer its own products. We compare mortgages from over 90 lenders including high street banks, building societies, specialist lenders and private banks. This regularly surfaces deals that borrowers would never find on their own — particularly for those with complex income, adverse credit or non-standard properties.
The Mortgage Application Process
Whether you are a first-time buyer, remortgaging or investing in buy-to-let, the process follows a similar pattern. Understanding what is involved helps you prepare properly and avoid delays.
Step 1 — Free consultation. Call 01273 907 234 to discuss your circumstances, goals and budget. We assess your income, outgoings, deposit and credit position. This typically takes 20–30 minutes and costs nothing.
Step 2 — Agreement in Principle. We obtain an AIP from the most suitable lender, confirming how much they are willing to lend. This strengthens your position with estate agents and sellers. We can typically arrange this within 24 hours.
Step 3 — Property search and offer. Armed with your AIP you search for properties knowing exactly what you can afford. When you find the right one and your offer is accepted, we move to full application.
Step 4 — Full application. We prepare and submit your application with all required documentation. The lender instructs a valuation of the property and assesses your application. This typically takes 3–5 weeks.
Step 5 — Formal offer. Once the lender is satisfied they issue a formal mortgage offer. Your solicitor reviews this alongside the property searches and contracts.
Step 6 — Completion. Contracts are exchanged, completion date is set, and you pick up the keys to your new Sussex home. We are available on 01273 907 234 throughout the entire process.

Making the Right Decision for Your Circumstances
Every mortgage decision involves trade-offs. A lower rate might come with higher fees. A longer fix gives more certainty but less flexibility. A higher deposit unlocks better rates but delays your purchase. The right answer depends entirely on your specific circumstances — your income stability, how long you plan to stay, your risk tolerance, and your wider financial goals.
This is precisely why professional mortgage advice exists. A comparison website can show you rates but it cannot assess which rate you will actually be approved for, whether the lender’s affordability model suits your income structure, or whether the product’s early repayment charges align with your plans. These are the questions that determine whether you get the right mortgage or merely a mortgage.
Sussex’s property market amplifies these considerations. A 0.3% rate difference that might save £50 per month in a cheaper area saves £100–£150 per month on Sussex property prices. Over a 5-year fix that is £6,000–£9,000. Over a 25-year term the saving is £30,000–£45,000. These are life-changing sums that justify spending 30 minutes on the phone with a qualified adviser.
