How it works

Here's how Groundbase works.

An owner-build involves income, debts, equity, a construction loan, a draw schedule, change orders, and a permanent payment — all moving at once, all connected. Groundbase is built to hold all of it together so the financial picture stays clear while the project is still in motion.

01

Starting point

The build has to fit inside what the finances can support.

Most owner-builders start with a build number and sort out the financing later. Groundbase starts the other way. Income, debt, cash, and current-home equity come first — because DTI sets the ceiling before any construction cost enters the picture.

Strong post-build position. Your permanent mortgage keeps monthly obligations manageable with healthy budget room.

02

Project setup

Turn the project into a number the finances can work around.

Construction cost is one line. Soft costs, contingency, and allowances are the rest — and most owner-builders don't see the full cost until they're already committed.

03

Build tracking

The build moves. Every draw and change order moves with it.

Once construction starts, the financial picture is not a document anymore — it's a running ledger. Every draw that closes, every change order that gets approved, lands in one place.

Risk monitoring

When the cushion shrinks, you need to know before the lender does.

Overages stack. Groundbase watches the gap between the plan and what is actually happening — how much contingency is left, how far the cost has moved, whether there is a funding shortfall — and gives you the real project health signal.

Full picture

Does the project work? Here is where you find out.

Groundbase keeps a running view of the complete picture: where all the money is coming from, what the finished payment will be, how much cash will be left after close, and what is most likely to change the outcome.

Watch now

Window package change order adds $18,600 to the projected cost.

Current funding leaves a remaining gap of about $30,000 if nothing else changes.

Finished monthly payment is still workable, but no longer comfortably loose.

Common questions

Questions about how Groundbase works

Setup, timing, data connections, and what the tool actually does during an active build.

What it adds up to

One financial picture. From first numbers to finished home.

No spreadsheet holds all of this together. Groundbase does — and it stays current while the project is still moving, not just at the start when everything is still clean.
