Complete Guide to Viewing Property in London: What Taiwan Buyers Need to Know

For many buyers from Taiwan, flying to the UK for property viewings is both time-consuming and logistically demanding. London’s property market moves fast, and the buying process differs significantly from what buyers are used to back home. Without thorough preparation, it’s easy to miss ideal opportunities — or, worse, discover hidden problems only after completing a purchase. IREIS Properties has been helping overseas Chinese buyers navigate the UK property market for years, and we know that every successful purchase begins long before you set foot in a viewing. This guide walks you through everything you need to know, from financial preparation and on-the-day viewing tips to due diligence and the most common mistakes overseas buyers make.

Plan Viewings in Advance

Quality properties in London often receive multiple offers within days of listing. Book viewings early and have your proof of funds ready so you can move quickly when the right property appears.

Commission a Qualified Surveyor

A Building Survey is a critical safeguard for overseas buyers. A professional surveyor will identify structural problems — damp, roof defects, subsidence — that are invisible to the untrained eye.

Understand Stamp Duty & Costs

UK Stamp Duty Land Tax (SDLT) applies on a tiered basis, and overseas buyers face additional surcharges. Use a stamp duty calculator before budgeting so there are no surprises.

Work with a Specialist Agent

IREIS Properties provides end-to-end bilingual support — from shortlisting properties and accompanying viewings to reviewing contracts — ensuring Taiwan buyers have expert guidance at every step.

Before You Travel: Financial Preparation and Document Checklist

One of the most common mistakes Taiwan buyers make is underestimating how quickly they’ll need to demonstrate financial readiness once in London. Estate agents in competitive areas routinely ask buyers to provide proof of funds — or a mortgage Agreement in Principle (AIP) — before accepting an offer. If you plan to buy with a mortgage, start the process at least six to eight weeks before your viewing trip. Overseas buyer mortgages require more documentation than standard UK residential mortgages, typically including: three months of payslips (or two years of company accounts for self-employed buyers), passport and proof of address, bank statements covering the past three to six months, and proof of tax residency in Taiwan.

Beyond the mortgage, you need a clear picture of your total purchase costs. In addition to the purchase price, budget for solicitor (conveyancing) fees, Land Registry fees, a Building Survey, and Stamp Duty Land Tax (SDLT). Because SDLT is calculated on a tiered basis and overseas buyers face an additional surcharge, we strongly recommend using our UK Stamp Duty Calculator to estimate your actual tax liability before locking in a budget. Getting this wrong at the planning stage can derail a purchase at the worst possible moment.

Before choosing target locations, do your area research. London’s zones vary enormously in rental yields, capital growth potential, transport links, and lifestyle offer. Taiwan buyers looking for a self-use property with investment upside often focus on Zone 2–3 Tube-connected areas such as Canary Wharf, Stratford, and Balham. For pure investors, cities like Manchester, Leeds, and Birmingham offer stronger rental yields. IREIS Properties advisers are well-versed in current market conditions across all these locations and can build you a targeted shortlist matched to your budget and objectives.

On the Day: What to Look for During a London Property Viewing

The moment you walk through the door, your inspection needs to go well beyond the décor. Many first-time overseas buyers are swayed by beautifully staged interiors and miss the structural details that will matter most over time.

Structure and Exterior

Examine the external walls for cracks, staining, or spalling brickwork. Check guttering, downpipes, and drains for rust or blockage. Victorian and Edwardian properties are particularly prone to rising damp and penetrating damp; check skirting boards and lower walls for white salt deposits or dark tide marks.

Internal Systems and Appliances

Test every light switch, socket, and tap. Ask about the age and service history of the boiler — UK combi boilers typically need replacing every 10–15 years and a failing unit represents a significant near-term cost. Check the property’s Energy Performance Certificate (EPC) rating; stricter EPC minimums for rental properties may affect lettability.

Neighbourhood and Amenities

Schedule viewings at two different times — a weekday daytime and a weekend evening — to assess noise levels and foot traffic. Walk the route to the nearest Tube or rail station. For buyers with school-age children, check Ofsted ratings for nearby schools. If you cannot travel in person, IREIS Properties offers a dedicated proxy viewing service: our UK-based advisers conduct a live video walkthrough and submit a detailed written report, so you have a complete picture of the property without leaving Taiwan.

After the Viewing: Due Diligence and Property Assessment

Once you’ve identified a property you want to pursue, resist the urge to make an offer before completing your due diligence. In the UK, offers are legally non-binding until contracts are exchanged. For the survey, choose a RICS HomeBuyer Report (Level 2) for modern homes or a full Building Survey (Level 3) for older properties. A good surveyor’s report identifies defects and provides ammunition for renegotiating the price if significant problems emerge.

Your solicitor handles Legal Authority searches, environmental searches, and water searches — uncovering development plans, flood risk, or contamination. For leasehold flats, scrutinise the lease length, ground rent terms, service charge history, and the management company’s reserve fund. If the lease has fewer than 80 years remaining, the cost of extension rises sharply and mortgage lenders may refuse to lend — address this before exchange.

Making an Offer, Exchanging Contracts, and Completing: Five Pitfalls to Avoid

In England, an accepted offer creates no legal obligation on either party until contracts are exchanged — meaning sellers can accept a higher offer even after agreeing to yours (known as “gazumping”), and you can withdraw without penalty, but any professional fees paid to date will not be refunded. Cross-reference asking prices with Land Registry sold prices for comparable properties in the same postcode for a more objective benchmark.

Leasehold flats with fewer than 80 years remaining become significantly harder to mortgage and sell. Legal fees, survey fees, mortgage arrangement fees, and currency exchange costs can add up to 3–5% of the purchase price on top of stamp duty — budget for this from the start. Taiwan buyers are also exposed to TWD/GBP exchange rate fluctuations; a forward contract with a specialist FX broker can lock in your rate and protect your budget. IREIS Properties can introduce you to trusted currency partners to help optimise your conversion timing and cost.
