1-room flat with bedroom, balcony and Thames view, Greenwich Peninsula

B2 is the worst grade in the rating scheme and means that work is needed on the external wall. In this situation, lenders regularly require a costed and funded remediation plan with fixed dates before they will commit. The listing itself refers to a Letter of Assurance that the bank will want to see. How to check: before any reservation, request the complete EWS1 form, the Letter of Assurance, the current Fire Risk Appraisal of External Walls, the remediation resolution with a cost breakdown, funding source and timetable, and written confirmation of who bears the costs. In parallel, submit a mortgage agreement in principle to at least three lenders with exactly these documents. Whether and to what extent purchasers are covered here by cost-protection rules must be clarified with a solicitor in the country before purchase.

384,40 £ a month equates to around 92 £ per m² a year, assuming roughly 50 m². A directly comparable property from the same housing association on the peninsula is 338,01 £, and a further comparable property in Greenwich is 226,71 £. Over ten years, the difference to the cheaper comparable property alone adds up to a five-figure sum. In addition, there is no information at all on the reserve fund balance, past top-up demands, or approved works. How to check: request the last three years' service charge accounts, the current budget, the reserve fund balance, and the minutes of the last leaseholder or resident meeting, together with written confirmation of any planned one-off charges. The standing of the building's finances and the question of outstanding contributions from the previous owner should be established here before purchase; the legal position on this should be checked in the country.

Under size, the listing only refers buyers to the agent. Without a floor area, the price per square metre cannot be calculated, and that is exactly what decides whether 375.000 £ is reasonable. Between 45 and 58 m², at the same price, there is a difference of more than 2.000 £ per m². How to check: ask the agent in writing for the usable floor area, additionally pull the floor area recorded in the EPC register, and measure the property yourself at the viewing. Do not make an offer without a reliable floor area.

115 years remaining is unproblematic and well above the threshold at which lenders become uneasy. What is a burden is the 100 £ ground rent a year, because a comparable property in the area has a 250-year term and modern leases often manage without any significant ground rent. How to check: read the full lease, in particular the clause on increasing the ground rent, the service charge apportionment, and any consent requirements on resale or letting. A current title register, which should be obtained before purchase, shows what obligations follow from the register.

The listing claims a good energy rating but states neither a letter grade nor a figure. With communal heating, it is also the heat network's tariff that decides the actual costs, not the efficiency of the flat alone. How to check: request the EPC with its issue date and rating, additionally search the public register by address, and inspect the heating bills for the last two years. What energy-related obligations apply here for owners and landlords should be checked in the country before completion.

The same flat is simultaneously offered as a 25 per cent share for 93.750 £. That grosses the full price up to 375.000 £, but it is not market evidence, because shared ownership and outright ownership have different groups of buyers and price levels. At the same time, a property that is permanently also marketed as a share narrows the circle of future resale buyers. The fact that the seller's contact details are only released after registration delays the document review. How to check: clarify in writing whether, on an outright purchase, the housing association's pre-emption, consent or resale clauses apply.

The Thames-front position on the peninsula lies in a tidally influenced area that is protected by the barrier and the river walls; the residual risk of the defences failing remains and is asked about by insurers and lenders. The flat on the first floor is in this respect considerably better placed than a ground-floor unit. How to check: pull up the official flood map for the address, and check the building's insurance policy for flood cover and the excess. The official maps shown in the dossier can be called up directly at the property via the layers icon at the top right of the location map.

For the Greenwich Peninsula area, a price analysis based on official price paid data shows a change of around minus 5.5 per cent over the last twelve months, and around minus 6.3 per cent for flats. Anyone buying at the top of the range today bears the risk of not being able to sell at break-even in two to three years, especially once purchase costs and selling costs are added. How to check: before making an offer, pull the actual achieved sale prices for one-bedroom units in the same postcode area from the official price paid database and base your own offer on them.

The listing is silent on Stamp Duty Land Tax. At a purchase price of this size, that is a noticeable sum which arises in addition to solicitor's, surveyor's and Land Registry fees and changes the equity planning. How to check: have the tax liability calculated using the official calculator for the planned purchase price and your own status, and build it into the budget before making an offer.
