LANDSHILOH · DEVELOPMENT AND INVESTMENT RESEARCH
A useful land development budget explains what is priced, what is estimated and what remains unknown. A contingency cannot make an incomplete scope complete. Build the base budget from a defined concept, then test uncertainties with the professionals responsible for the work.
Organize the full scope
Separate acquisition, investigations, design, applications, site work, utilities, construction, financing and holding costs as relevant. Ask each provider to identify inclusions, exclusions and assumptions. Track quote dates and the concept version used. Avoid placing an unpriced task in the contingency column simply because its scope has not yet been investigated.
Assign uncertainty to specific items
List the issues that could change cost: excavation conditions, drainage design, service routes, revised layouts or longer holding periods. Ask the appropriate team members how to investigate each issue and what range is supportable. Keep allowances, reserves and scenario changes clearly defined so costs are not omitted or counted twice. Do not select a universal contingency percentage without considering the project.
Test decision scenarios
Compare a base case with slower timing, higher site costs or a reduced usable area. Identify which changes would require redesign or a pause. Record the evidence behind estimates and who approves updates. The budget should support decisions at each stage rather than imply precision that early feasibility work cannot provide. Seek qualified financial advice for financing and investment decisions.
Working checklist
Use these headings in your parcel file. For each item, record the source, date, responsible reviewer, outstanding question and next action. Keep confirmed findings separate from estimates and assumptions.
- Complete cost categories
- Quote dates and exclusions
- Specific uncertainty register
- Scenario assumptions and decision limits
- Update and approval responsibilities
Practical example
A budget includes a road estimate but excludes a drainage crossing pending design. Calling the entire road fully priced would hide the gap. Show the quoted road scope, the unresolved crossing and the investigation needed to estimate it, then test the impact on the project before relying on a single total.
Illustrative scenario only; not a property listing, valuation or assurance of feasibility.
Common question
Can one contingency percentage cover every development unknown?
A percentage does not identify missing work or explain risk. Define the scope and uncertainties first, then discuss appropriate allowances and scenarios with the qualified project and financial team.
