Brokers love pitching buy-to-let properties as easy "passive income." But the truth is, the space between what they promise and what you actually sign as paperwork is where they earn their commissions.
Here are three common lines you will hear in London and Dubai, along with the real UK and UAE rules. Remember: The two markets (the UK and the UAE) run on completely different legal systems, so do not mix up their tax or property laws.
Lie #1: The numbers work themselves
UK Reality: Two hidden costs quickly eat into your profits.
- Stamp Duty Surcharge: Since October 31, 2024, buying an extra property comes with a 5% extra tax rate. Unlike regular home buyers, you pay this 5% extra on the entire purchase price even the portion under £125,000. For a £300,000 buy-to-let property, you are looking at around £20,000 in Stamp Duty Land Tax (SDLT) before you've spent a penny on the property itself.
- Mortgage Interest Taxes (Section 24 - Finance Act 2015): Individual landlords can no longer write off mortgage interest as a business expense. Instead, you get a flat 20% tax credit. If you are in a higher tax bracket (40% or 45%), you actually end up losing money on the interest portion of your payments. Many brokers suggest setting up a limited company (SPV) to get full interest relief, but doing this means losing first-time buyer perks, and properties over £500,000 can face a flat 17% SDLT rate.
UAE Reality:
- It’s true that Dubai does not charge income tax on rent or capital gains tax for individual owners. So that part of the pitch is true.
- What brokers gloss over are service charges. Mandatory RERA-regulated service charges (tracked through the Mollak system) usually take away 15% to 25% of your total rental income.
- A Business Bay apartment advertised with a 7.1% gross yield often drops to around 5.7% net once you pay the service charge. Plus, these charges increase by 3% to 6% every year. Always look up the official DLD/RERA service charge index for the specific building and do not trust community averages.
Lie #2: Guaranteed yield
UAE reality:
- "Guaranteed ROI" is just a marketing term for off-plan property launches, not a legal promise.
- Actual rent prices are set by the RERA Rental Index, which puts a cap on how much you can raise rent for existing tenants. The index was updated in 2026 specifically to make return projections more realistic.
- Most "guaranteed" offers are just developers paying you back a portion of your own money over 2–3 years out of the original purchase price. Always ask what happens to your return once that fixed period ends.
UK reality:
- UK brokers rarely say "guaranteed," but they will quote high gross yield numbers that ignore real costs like letting agent fees (usually 10%–15% of rent), local council landlord licenses, and "void periods" (months when the property sits empty).
- Always ask for the net yield after factoring in SDLT, current mortgage interest rates, management fees, and energy efficiency (EPC) compliance costs.
Lie #3: You can sell or evict whenever you need to
UK Reality:
- The eviction system completely changed on May 1, 2026, under the Renters' Rights Act. "No-fault" evictions (Section 21), which let landlords kick out tenants without a reason—were completely abolished.
- All tenancies are now open-ended. To get your property back, you must go through the courts using specific Section 8 grounds (like unpaid rent, wanting to sell, or moving in yourself) and give proper notice.
- Handing out an invalid Section 21 notice can cost you a local council fine of up to £7,000. If a broker claims evictions are quick and easy, they are referencing rules that no longer exist.
UAE Reality:
- Selling is not always seamless either. If you have unpaid service charges, the Mollak system flags your title deed, blocking you from selling or refinancing until the debt is paid.
Additionally, updated rules require sale money to go directly to the person named on the title deed, not to someone holding a Power of Attorney to stop property fraud. Hence, selling is still completely doable, but ensure you check for unpaid service charges as that part is just as critical as checking out your tenant.
The Bottom Line
These sales pitches sound convincing because there is a kernel of truth in them. Dubai really has zero income tax, flyers do show high gross yields, and eviction processes do exist.
What gets left out is the tax surcharges, the loss of interest write-offs, the ongoing service charges, and the strict legal notice periods. Always demand net figures from your broker and ask them to show you the exact laws backing up their claims.
The difference between a good investment and an expensive surprise often lies in the costs, taxes, regulations and assumptions that don't make it into the sales pitch.
