The contract determines who carries price risk, how allowances move, what evidence supports draws, and when the budget changes.
Understand where the risk sits
A fixed-price contract generally gives the borrower a stated contract amount for an agreed scope. The details matter: allowances, exclusions, escalation clauses, site conditions, owner changes, and work outside the contract can still move the final cost. The label is not a substitute for reading the risk language.
A cost-plus contract generally passes actual project costs through to the owner and adds a builder fee. That structure can provide transparency and flexibility, but it requires disciplined estimates, reporting, approvals, and contingency. The construction file still needs a financeable budget.
Find the numbers that are allowed to move
Review every allowance and ask what selection it is meant to cover, whether labor is included, what happens when the selection exceeds the allowance, and how the difference is paid. Identify deposits required before work is complete and confirm whether the draw process can support them.
Then review exclusions. Landscaping, appliances, utility extensions, engineering, soil work, retaining walls, pools, flatwork, and owner-purchased materials often sit outside the obvious house price. An excluded cost is still a project cost.
Make the contract and budget tell the same story
The lender budget, signed contract, plans, specifications, and appraisal should describe one project. If the contract includes a scope that the budget omits—or the plans show features the contract excludes—the inconsistency will eventually surface.
Before signing, have the appropriate legal and construction professionals review the agreement. Financing review can identify budget and draw implications, but it is not a substitute for legal advice about the contract.
