No — quotes are based on general inclusions and are not fixed until the following steps are completed:

Site Assessment ($5,000): Full survey, slope review, soil classification, and access check

The Site Assessment determines if your quoted install conditions are feasible or if additional costs may apply.

Once your Prelim and Site Assessment are complete, and final contract is issued, your price is fixed.

Valid for 60 days from issue

Includes manufacture, delivery, installation, and approvals

Subject to no changes in site or layout

Rural delivery, overlay reports, or slope issues may add cost — but these are quoted in advance during assessment.

Quotes clearly separate Expandify and builder charges to assist with budgeting and finance.

Do You Offer Finance?

Expandify doesn’t offer in-house finance but can refer you to brokers familiar with modular and secondary dwelling lending. 

Lenders may request your quote and council eligibility before issuing finance pre-approval.
