Off-plan or completed: which purchase suits your timetable?

Two apartments can look similar on a website and ask very different things of a buyer. One is finished: you may be able to inspect the actual layout and see how the building works. The other is off-plan or under construction: you are assessing drawings, specifications, a developer and a future completion. Price alone does not tell you which is a better fit.

Begin with your own timetable. If you need potential rental income in the near term, a completed, lettable home may be more relevant, although occupancy and rent still need checking. If you can wait and want to choose from plans before completion, off-plan may suit you, provided your finances can accommodate delays and the contract is properly reviewed.

What a completed building lets you check

You can stand in the actual apartment, assess daylight, noise, storage, finishes and the view. Ask about building management, service charges, maintenance and any existing tenancy. A property described as ‘completed’ is not automatically tenanted, and a tenant in place is not a promise they will remain. Verify the rental position, tenancy documents and running costs rather than assuming an immediate return.

Waterhouse Gardens is a completed Salboy development in our current selection. Its status offers a different starting point from an apartment that is still being built. Ask which exact units are available, whether they are tenanted, and what their actual income and expenses are. Avoid transferring a general scheme-level claim to an individual unit.

What off-plan asks you to evaluate

The HomeOwners Alliance off-plan guide sets out risks around changes and delays. You need to understand what is included in the agreed price, how the deposit is protected, what happens if completion slips and whether finance will still be available then. Your own solicitor should check the legal documents; an artist’s impression is not a contract.

Obsidian is an under-construction scheme, while Trafford Waters has a later expected completion. Different timelines change how long capital is committed before a property can potentially produce rent. A forecast of capital growth during construction is a possibility, not an entitlement; values could also disappoint. Compare the purchase price with relevant completed stock and account for taxes, borrowing, service charges and possible void periods.

The difference is not just ‘risk versus safety’

A finished apartment still faces tenant demand, repairs, management and resale risk. An off-plan contract adds developer and construction questions, but may offer a broader choice of units while the building is being marketed. Some buyers prefer to inspect a finished home; others are comfortable analysing plans in detail. Neither choice is automatically more sophisticated.

Think about how much certainty your own circumstances require. Will you need a mortgage at completion? Could you cover a later-than-expected handover? Do you want to see the exact view and finish before paying? Are you comfortable waiting for a first tenant? Your answers should determine which stock to consider, not an unqualified claim that one category ‘outperforms’ another.

A like-for-like comparison records the actual unit price, specification and all transaction costs; the expected completion or availability date; independently checked rental comparables; and the current building costs. Add a pessimistic scenario for a delayed letting or unforeseen expense. The difference between a glossy gross yield and net cash remaining after costs can be material.

A choice grounded in your plans

If completed stock is your priority, focus on inspectable units and their tenancy documents. If off-plan suits your horizon, focus on contractual protections and the developer’s delivery information. Ask for the current unit-specific position in either case. Our developments list makes the stage and named developer of each scheme clear; contact the team if you want to compare an available completed apartment with an off-plan alternative.

Remember the exit, too

Imagine needing to sell earlier than expected. A completed apartment offers buyers something they can inspect, but its price will still depend on the prevailing market and the building’s costs. An off-plan contract may restrict assignment or resale before completion; ask your solicitor rather than assuming you can simply pass on the reservation. Your own investment horizon should be long enough to accommodate uncertainty without relying on a quick exit.

If buying with a partner or using a mortgage, make sure both understand when cash must be available and what happens if circumstances change. The apparent discount of one unit to another is only meaningful after adjusting for delivery stage, specification, location and all costs. Ask for current written terms for each unit, not general claims about off-plan or completed property as categories.

Neither route removes market risk. A completed apartment can reveal its condition but still face empty periods or unexpected repairs. An off-plan apartment can offer a particular floor or layout but requires confidence in future delivery. Put both on a conservative cash-flow model with an allowance for voids and costs, then obtain professional advice on the assumptions that matter most to you.
