    Advisory review, not property sourcing or mortgage broking.

    Before offer, exchange or commitment

    What your independent purchase review can cover

    Send a property you have found, its asking price, rent evidence and proposed finance. We agree the questions, evidence, fee and written deliverables before starting. This is a second opinion on the purchase decision — not a listing service, building survey or legal clearance.

    Evidence and missing information

    Check price and rent assumptions against comparable evidence; record what is supplied, unverified or still needed from the seller, surveyor, solicitor or lender.

    Downside and cash commitment

    Separate gross rent from net income. Include voids, repairs, management, compliance, acquisition costs and finance sensitivity; identify the cash buffer needed if assumptions weaken.

    A written decision brief

    Set out the risks, assumptions, questions before commitment and conditions that could change the conclusion. Your agreed scope defines the analysis, exclusions and decision options.

    Bring the questions that could change your offer

    • Single-let: does net income still work after voids, repairs and a refinance?
    • HMO: are room rents, licence conditions, planning position and compliance costs evidenced?
    • Commercial or mixed use: what do lease terms, tenant covenant, breaks, capex and vacancy imply?
    • Portfolio: does this acquisition increase lender, location or tenant concentration?
    • Overseas: are FX, source-of-funds, ownership and UK/home-country tax questions coordinated before commitment?

    Scope first. Fee agreed. No promised return.

    Fees depend on the asset, documents, complexity and depth of review. Request a written scope, fixed deliverables, exclusions and fee before instructing. Missing information can limit conclusions; a review cannot remove market risk or guarantee a successful purchase.

    Solicitors handle legal diligence, surveyors assess condition, and appropriately qualified or authorised professionals provide tax and regulated financial or mortgage advice. We identify questions for those professionals, not replace them.

    Key facts

    • A portfolio is not the sum of its assets — it is the sum of its correlations.
    • The weakest assets in a portfolio are usually the ones bundled deliberately.
    • Compliance capex across a portfolio compounds: one EPC pathway per asset becomes a programme.
    • Debt maturity clustering is a portfolio-level risk that asset-level diligence never surfaces.
    • Share purchase versus asset purchase changes tax, liability inheritance and timetable materially.
    • Overseas entities acquiring UK property must be on the Register of Overseas Entities to be registered as proprietor.
    • Mandate scope, suitability, fees and specialist responsibilities are confirmed before instruction. No minimum capital threshold is published.

    Portfolio deals are sold on the blended yield. That blend is where the problems hide: the two assets carrying the concentration risk, the three with a compliance liability, and the refinancing window that lands on all of them at once. Portfolio diligence is a different exercise from doing asset diligence several times.

    What does portfolio-level due diligence add over asset-level review?

    Correlation. Asset diligence tells you each building is acceptable. Portfolio diligence tells you what happens when the same employer, the same city economy, the same lease expiry year or the same refinancing window affects several of them simultaneously. That is the exposure that turns a soft market into a forced sale.

    How do you verify the income across a portfolio?

    From the leases, not the schedule. Rent schedules are prepared by the vendor and reconcile to the marketing, not necessarily to the documents. We sample and reconcile: passing rent, review dates, breaks, incentives still running, service charge caps and irrecoverables, then rebuild the net income line.

    Should you buy the assets or the company?

    It changes tax, liability and timetable. A share purchase can carry a different SDLT position but inherits the company's history, including tax, employment, environmental and litigation exposure. An asset purchase leaves that behind but is usually slower and taxed differently. Both should be modelled before the structure is agreed.

    What is the most commonly missed portfolio risk?

    Debt maturity clustering. Several facilities maturing within the same short window force a simultaneous refinancing into whatever market exists then. Spread maturities, or price the risk of refinancing all of it at once at a materially higher cost.
