Budget Planning Tips for 2025
1. Add Contingency for Cost Increases
With ongoing material price volatility, budget an additional 15-20% contingency beyond your base construction estimate. This protects against mid-project cost increases and change orders.
2. Factor in Financing Costs
Construction loans typically cost 1-2% more than permanent mortgages. Budget for interest payments during the 6-12 month construction period, which can add $15,000-40,000 to your total project cost.
3. Don't Forget Soft Costs
Beyond construction, budget for temporary housing, storage, utilities during construction, and moving expenses. These "soft costs" typically add 5-10% to your total project budget.
Money-Saving Tips from the Pros
- • Choose the right contractor to avoid costly mistakes and delays
- • Lock in material prices early when possible
- • Consider value engineering to optimize your budget
