Understanding Development Property Before Assessing Its Potential

1. What Is a Development Property?

In the 99DIG assessment context, a development property is a property being considered partly because of a proposed change, improvement, redevelopment, subdivision, construction or other future property use.

It may be vacant land, underused land, a property containing older improvements, or an existing site being considered for a different form or intensity of use.

The important point is that the development idea relates partly to a future condition rather than only to what physically exists today.

2. Development Land and Ordinary Property Are Not Always Assessed the Same Way

A completed property can often be described mainly through its existing land, buildings, use, condition and market context.

A development property introduces another layer: the proposed scheme.

That means the assessment may need to consider both the existing site and assumptions about a possible future project.

The more the assessment depends on something that has not yet happened, the more important it becomes to identify assumptions clearly.

3. Start with the Existing Property — Not the Proposed Project

A common mistake is to begin with an exciting development idea before properly understanding the land on which that idea depends.

99DIG should first build the existing property profile.

Useful information may include:

• property address;
• land name;
• lot and survey plan references where available;
• land extent;
• existing buildings;
• current use;
• road access;
• frontage;
• general site characteristics;
• administrative location; and
• map location.

4. Identify the Land Extent Carefully

Development ideas frequently depend on land area.

A difference in site extent can affect the scale of the concept, the amount of usable land, access arrangements and the financial assumptions built around the project.

Where reliable survey information is available, the user should enter the relevant extent rather than estimate it casually.

99DIG may accommodate locally familiar land measurements such as Acres, Roods and Perches where the relevant input is provided.

5. Site Shape Can Matter

Two parcels with the same total land area may not provide the same development context.

One may have a regular configuration while another may be narrow, irregular or divided by physical constraints.

Site shape can therefore be relevant when a development concept is being considered.

99DIG can record descriptive site information without claiming that a particular design will physically fit unless that has been separately established.

6. Road Frontage and Access Need Attention

Access is an important part of understanding a development site.

Useful factual information may include:

• type of access road;
• approximate road width where known;
• site frontage;
• direct or indirect access;
• existing vehicle access; and
• other observable access characteristics.

These details provide context, but the existence of physical access should not automatically be treated as confirmation that it satisfies every requirement of a proposed development.

7. Existing Buildings Should Not Be Ignored

Development property is not always vacant land.

A site may contain a house, commercial building, warehouse, incomplete structure or another improvement.

The development concept may retain, alter or remove those improvements.

99DIG should therefore record what currently exists separately from what the user proposes to do with it.

8. Understand the Current Use

Current use describes how the property is being used at the time of the assessment.

Examples could include:

• vacant land;
• residential use;
• commercial use;
• agricultural use;
• industrial use;
• mixed use; or
• another existing use.

Current use should remain separate from the user's proposed development.

9. Define the Proposed Development Clearly

Once the existing property is understood, the user can describe the proposed development scenario.

A useful description may identify:

• proposed property use;
• approximate number of units where relevant;
• proposed building area where known;
• proposed floors where relevant;
• parking assumptions;
• open-space assumptions;
• phasing where relevant; and
• other major elements of the concept.

10. Proposed Use Is an Assumption Until Confirmed

A landowner may believe that a site is suitable for apartments, shops, a hotel, offices, housing lots or another development.

That idea can be useful for preliminary assessment.

But the assessment should distinguish between:

11. Planning Potential Is Not Planning Approval

A development concept may appear physically attractive or commercially interesting without being formally approved.

The user should not interpret a 99DIG development assessment as confirmation of zoning, planning permission, subdivision approval, building approval, density, permitted use or another statutory matter.

Those matters should be confirmed separately with the relevant information and authority where required.

12. Map Information Provides Context, Not Approval

A map location can help identify the property and understand its surroundings.

It can support observations about accessibility, nearby development, distance and general geographic context.

A map should not, however, be used as proof of surveyed boundaries, ownership, planning permission or development rights.

13. Look at the Surrounding Development Pattern

The surrounding area can provide useful clues about the context in which a proposed project would operate.

A user may observe nearby:

• housing;
• apartments;
• commercial activity;
• industrial uses;
• tourism-related properties;
• agricultural land;
• public facilities;
• transport connections; or
• undeveloped land.

These observations can support market understanding, but surrounding development should not automatically be interpreted as permission to develop the subject property in the same way.

14. Identify Physical Site Constraints

Not every part of a site may necessarily contribute equally to a development concept.

Depending on the property, there may be physical characteristics that require further investigation.

Examples might include unusual terrain, drainage conditions, existing structures, access limitations or other site-specific features.

99DIG can record known observations while leaving specialist conclusions to the appropriate technical investigation.

15. Infrastructure Can Affect the Development Concept

A proposed development may depend on infrastructure and utility availability.

Depending on the project, the user may consider available information relating to:

• road access;
• electricity;
• water;
• drainage;
• telecommunication access;
• wastewater arrangements; and
• other relevant services.

Presence near the site does not automatically confirm that capacity or connection will be available for the proposed project.

16. A Development Idea Needs a Market

A development concept may be physically imaginable but still needs users, buyers, tenants or another source of demand if it is intended as a commercial project.

The user should therefore ask who the proposed development is intended for.

A residential project may depend on buyers or tenants. A retail project may depend on occupiers and customers. A tourism project may depend on visitors.

17. Define the Proposed Development Product

A clearer development assessment requires more than the statement “build something on the land.”

The proposed product should be described as clearly as reasonably possible.

For example:

• number and type of residential units;
• approximate commercial floor area;
• number of proposed lots;
• proposed hotel rooms;
• warehouse area;
• office accommodation;
• mixed-use components; or
• another relevant development output.

18. Development Density Should Not Be Invented

Increasing the number of units may increase expected project income in a spreadsheet, but that does not prove that the site can support them.

The development scale entered into 99DIG should therefore reflect the user's actual scenario or available supporting information.

Unsupported density assumptions can distort both expected income and development cost calculations.

19. Understand the Development Timeline

Development does not happen instantly.

Time may be required for investigation, design, approvals, site preparation, construction, marketing, sales, leasing or other activities.

A preliminary development assessment should therefore consider the expected development period where relevant.

20. Development Cost Needs More Than One Number

A development budget is easier to understand when costs are organised into meaningful groups.

Depending on the project, preliminary cost information may include:

• site acquisition or land-related amount;
• site preparation;
• construction;
• infrastructure;
• professional and technical services;
• approval-related expenses;
• marketing;
• finance-related assumptions;
• holding costs;
• contingency assumptions; and
• other relevant project costs.

The exact cost structure depends on the project and information available.

21. Construction Cost Is Not Total Development Cost

Users can easily focus on the cost of the building itself.

A project may involve other expenditure before, during and after construction.

Therefore, using only a construction figure may create an incomplete development picture.

22. Contingency Is About Uncertainty

Development projects can encounter costs that were not precisely known at the beginning.

Where the user includes a contingency assumption, it should be shown clearly rather than hidden inside another cost item.

The amount should reflect the user's assessment information rather than an arbitrary figure inserted only to complete the calculation.

23. Expected Revenue Must Be Connected to the Proposed Product

Expected development income should arise from the actual development scenario being assessed.

For a project intended for sale, this may involve expected sale amounts for proposed units.

For a rental development, it may involve expected rental income.

For a mixed project, more than one income stream may be relevant.

99DIG should preserve the connection between the proposed product and the expected income assumption.

24. Expected Selling Price Is Not a Guaranteed Selling Price

Future units do not yet have completed future transactions.

The user may estimate potential selling amounts using available market information and assumptions, but those amounts remain uncertain.

Future market conditions may differ from the conditions observed when the assessment is prepared.

25. Use Relevant Market Information

Development market evidence should relate as closely as reasonably possible to the proposed product.

If the proposal is for apartments, unrelated bare-land advertisements do not explain the expected apartment selling market by themselves.

If the project involves commercial space, residential rents may not provide meaningful evidence of commercial occupation.

99DIG can organise different types of market information according to the part of the assessment they support.

26. Keep Current Evidence and Future Assumptions Separate

Development assessment often combines information from different time perspectives.

Mixing these categories can make a development result appear more certain than the underlying information supports.

27. Development Margin Needs Context

A user may want to understand the relationship between expected project income and expected project cost.

A development margin can help describe that relationship.

But a margin calculated from uncertain inputs remains dependent on those inputs.

If selling assumptions, costs or timing change, the resulting margin can also change.

28. A Positive Margin Does Not Automatically Mean “Proceed”

A numerical surplus can look attractive.

But the development decision may still depend on approval risk, construction uncertainty, market demand, finance, timing, site constraints and other factors.

29. Cash Flow Adds the Dimension of Time

Development costs and income rarely occur at exactly the same time.

Money may be committed during acquisition and construction, while income may arise later through sales, leasing or occupation.

A cash-flow view helps organise when those amounts are expected to occur.

This can provide more context than simply comparing one total cost with one total revenue figure.

30. Delay Can Change the Development Picture

If a project takes longer than expected, several assumptions may change.

Depending on the project, delay could affect:

• holding period;
• finance-related costs;
• construction prices;
• marketing period;
• sales timing;
• rental commencement; and
• overall project uncertainty.

Development time should therefore not be treated as a minor input.

31. Test What Happens When Costs Increase

A development assessment becomes more informative when the user can see how the result changes if an important assumption changes.

One useful scenario is an increase in development costs.

The purpose is not to predict that costs definitely will increase. It is to understand how sensitive the project may be if they do.

32. Test What Happens When Expected Income Falls

Another useful scenario is a reduction in expected selling or rental income.

If a relatively small change in income significantly changes the project outcome, that information may be important to the user.

Sensitivity testing helps reveal this relationship without claiming to predict the future.

33. Test What Happens When the Project Takes Longer

A third scenario can consider a longer project period.

This may help the user understand whether the assessment depends heavily on completing the project within a particular timeframe.

34. Consider Alternative Development Concepts

The first development idea is not necessarily the only possible scenario.

A user may want to compare a larger project with a smaller project, a sale-focused scheme with a rental-focused scheme, or another reasonable alternative.

99DIG can help organise scenarios, provided each one clearly states its own assumptions.

35. More Development Is Not Automatically Better Development

Increasing units, floor area or project scale may increase expected gross income in a calculation.

But a larger scheme may also involve higher cost, longer time, greater market exposure and additional uncertainty.

The assessment should therefore avoid assuming that the scenario with the largest gross income is automatically the strongest option.

36. Development Risk Should Be Visible

Development property contains uncertainty because the proposed outcome does not yet fully exist.

Depending on the project, relevant risks may relate to:

• planning or approval assumptions;
• site conditions;
• construction cost;
• construction period;
• market demand;
• selling or rental assumptions;
• finance;
• infrastructure;
• project delivery; and
• other property-specific circumstances.

Identifying risk does not mean that the project is unsuitable. It means recognising what could affect the expected outcome.

37. Unknown Information Should Not Be Invented

Development assessment can involve many inputs.

Some may not be known during an early-stage review.

If a planning parameter, construction figure, project duration or another important fact has not been established, the user should avoid presenting a guess as confirmed information.

38. A Simple 99DIG Development Assessment Journey

39. Do Not Read Only the Final Result

Development assessment contains more assumptions than many ordinary property assessments.

The user should therefore review the information behind the result.

Check whether the site extent, proposed development, development cost, expected income and timing assumptions reasonably reflect the scenario that was actually intended.

A precise-looking result does not make uncertain inputs certain.

40. What 99DIG Can Help With

Within the scope of a digital preliminary assessment, 99DIG can help users:

• organise existing site information;
• identify the development purpose;
• record a proposed development scenario;
• separate existing facts from future assumptions;
• organise relevant market information;
• record preliminary development costs;
• record expected development income;
• consider project timing;
• review selected development indicators;
• test alternative assumptions;
• identify information gaps; and
• produce a structured digital assessment output.

41. What 99DIG Does Not Confirm

A development assessment should maintain a clear boundary between digital analysis and matters requiring separate confirmation.

99DIG should not be interpreted as confirming:

• legal ownership;
• surveyed boundaries;
• planning permission;
• building approval;
• permitted density;
• subdivision approval;
• engineering suitability;
• structural feasibility;
• utility capacity;
• future selling prices;
• future rental income;
• project profitability; or
• completion of the proposed development.

42. Separate Professional Input May Still Be Required

A development project can involve several areas of specialist work.

Depending on the project and stage, separate input may be required from appropriate professionals or authorities in relation to matters such as planning, surveying, design, engineering, legal issues, costing, finance, taxation or formal property valuation.

99DIG does not need to replace these roles to provide useful preliminary digital assessment support.

43. Development Assessment Is Not a Feasibility Guarantee

A digital assessment may help a user understand whether a development concept appears worth investigating further.

It does not guarantee that the project is technically feasible, commercially successful or capable of obtaining the approvals required.

The result should therefore support the next decision rather than replace every investigation that may follow.

44. Final Development Review Checklist

Before relying on a 99DIG development assessment, the user can review:

• Is the correct property being assessed?
• Is the land extent reasonably supported?
• Are existing buildings recorded?
• Is current use correctly described?
• Is the proposed development clearly identified as proposed?
• Are planning assumptions separated from approvals?
• Is the proposed development product clearly described?
• Is relevant market information being used?
• Are expected selling or rental figures identified as assumptions?
• Are major development costs included?
• Has the expected development period been considered?
• Have important uncertainties been identified?
• Has sensitivity been considered?
• Are unknown facts still identified as unknown?

45. Final Thought

Development property is different because much of the decision can depend on something that does not yet exist.

That makes assumptions especially important.

A useful development assessment should show the existing property, describe the proposed project, organise market information, identify expected costs and income, consider time and make uncertainty visible.

99DIG is designed to bring those pieces together into a structured digital assessment that helps the user understand the proposed development scenario before making a larger decision.
