Product
A home build budget planner built for the real financial side of building.
Plan the budget, funding, draws, and affordability in one place, then keep everything in sync as costs change.
The system
Tools that stay connected as the build moves.
Each part solves a specific problem. The value comes from keeping all four connected.
Budget
A budget that stays useful after the first bid arrives.
Most budget tools stop at the estimate. Groundbase keeps the number alive - contingency, real costs, and soft costs tracked as the project becomes real.
- Soft costs built in from the start - permits, design fees, utility hookups.
- Contingency tracked separately so you always know what real buffer you have left.
- Real costs from draws and change orders update your budget health automatically.
- Variance flagged early, before it compounds into a bigger problem.
Funding
Every source of money, in one view.
Equity, sale proceeds, reserves, and debt only make sense together. Groundbase keeps them in one view so you can see the real coverage picture.
- Equity from your current home sits alongside your construction loan.
- Cash reserves tracked so you know what's actually available vs. committed.
- When proceeds come in short, the gap shows up immediately - not at closing.
- Scenario switching to see how combinations of bad news stack up.
Tracking
Build activity tied to financial impact.
Every draw, vendor, and change order should explain what it means for the budget. Groundbase makes that connection automatic.
- Each draw linked to a funding source - loan, cash, or sale proceeds.
- Vendor and contract activity tied to budget line items.
- Change orders update budget health in real time.
- Status updates that carry their financial meaning with them.
Affordability
The finished-home payment, visible from day one.
Most people don't see the real finished-home payment until the build is almost done. By then it's too late to change anything. Groundbase keeps it visible the whole time.
- Finished monthly payment calculated from your actual budget - not a ballpark.
- DTI shown during construction and after, the numbers lenders actually use.
- Payment pressure updates when the budget or funding assumptions shift.
- Budget health and affordability in one view, not two separate spreadsheets.
