Decision guide

Check the property before you spend on plans

Use the lot, funding, rent-cap and servicing screens to decide whether the next step should be design work, a builder conversation or more research.

  • Check the address
  • Compare funding agreements
  • Confirm the rent math
  • Budget the hidden costs

Compare Scope Before Price

Confirm whether drawings, permits, utilities, grading, access, finishes, taxes and contingency are included, excluded or allowances.

Check Commercial Terms

Compare payment schedule, change-order rules, warranty, insurance, site assumptions, completion definition and responsibility for permit corrections.

Resolve Property Risk First

A polished quote cannot solve an unverified zoning, servicing, drainage, tree or access issue. Keep those conditions visible in the contract conversation.

FAQ

Common questions, answered plainly

Should I choose the lowest ARU quote?
