Speaking Background
    Construction Cost & Tax Depreciation Specialist

    Mark Kilroy.

    I explain why property succeeds or fails during the hold, when cash flow pressure shapes investor behaviour and housing supply outcomes over time.

    My work focuses on reducing that pressure so assets are held, not forced to exit.

    Where Property Outcomes Are Decided

    After purchase, most properties enter a period of cash flow pressure.

    This period, known as the hold, is where outcomes are quietly determined. Investors either stabilise and hold, or are forced to exit earlier than planned.

    When exits occur, rental supply is lost. When assets are held, supply is preserved.

    Housing outcomes are shaped here, not at purchase.

    The Kilroy Curve - Illustrating the holding gap in property investment

    How Property Outcomes Are Managed During the Hold Phase

    Most property strategies focus on buying well or selling at the right time.
    Very few focus on what happens in between.

    The Kilroy Curve shows when property outcomes diverge.
    The HOLD Strategy defines what to do during that period.

    The HOLD Strategy visual — four levers adjusted continuously during ownership

    The HOLD Strategy breaks the ownership phase into four practical decisions that investors must actively manage during ownership.

    These are not stages you complete once.
    They are levers you adjust continuously as conditions change.

    HHOLD

    Long-term ownership through market cycles. Avoiding forced decisions during periods of pressure or volatility.

    OOPTIMISE

    Improving cash flow, efficiency, and performance. Rent, costs, structure, and operational decisions all matter here.

    LLEVERAGE

    Using equity carefully and at the right time. Growth should be deliberate, not emotional or reactive.

    DDEFEND

    Protecting cash flow and reducing downside risk. Buffers, structures, and decisions made before problems appear.

    This is where most property outcomes are quietly decided.

    Apply for a HOLD Review

    An independent review of how your property is performing during the hold phase, and where the highest-impact adjustments sit today.

    The HOLD Strategy is the execution layer of the Kilroy Curve.

    Private Advisory

    For investors and business owners who already own property, I offer a private HOLD Review.

    This is a structured assessment of holding risk, cash flow pressure, and decision timing, designed to identify where assets are vulnerable during the holding phase and what matters next.

    It is not acquisition advice.
    It is not a sales conversation.

    It exists to create clarity before pressure forces decisions.

    Applications are reviewed before confirmation.

    Advising the advisors.

    I work with property investors, business owners, accountants, and professional advisors where construction cost accuracy, depreciation defensibility, and cash flow outcomes matter.

    Ready to make better holding decisions?

    Property outcomes are shaped during the hold, when pressure builds and decisions matter most. Clear advice on construction costs, depreciation, and cash flow helps investors and businesses hold assets longer and avoid forced exits.
