I could not find the type of glue in the MSDS or much info on materials. Impressive factory and use of straw, however, low perm glues, foam, vapor barriers will not handle moisture well. If it is OSB/FOAM SIPs construction there will be issues at the seams. Crazy how the industry thinks glues, now to get air seals, will last the test of time.
IRC 2015 has strawbale code you build to it and have it inspected by the
local jurisdiction or hire a third party, or get an Engineers stamp. At that point the banks
should fund it but may want more down ( which should be on less than mainstream cost) since it is new or an "alternative" building material/method. Most banks just send out an inspector to make sure the money is being spent properly and don't get into the tech, especially if being built to code or stamped drawings.
Bag construction is basically
concrete per IRC code.
You can also get assumable loans to make selling easier.
Much of funding is how it is communicated, and how to negotiate creative financing. Check into hard money lenders too.
