Put Finance in Place

If you are not going to pay cash for the project, the main funding options are to secure a construction loan which can be used to pay for your HebHome and its erection as well as site preparation works.  This may also be available to fund your land purchase.  Below is a useful site which provides an overview and guidance on construction loans.

Once the building is complete, you then transfer this construction loan into a more traditional mortgage.

Typically interest rates for construction loans are higher than for mortgages.  A key benefit of a HebHome is the quickness of its construction, allowing you to move to a cheaper mortgage much faster than under traditional build.
