Most likely too new. Ask a lender how they are valued, as a stick built or like another atypical construction. That normally means they have to be valued by us, appraisers with like units, and few of them, means a lower than typical value. Maybe use some of the elements of this type in a typical stick build and that will not put it in the atypical place that makes them hard to value.
Hope that helps, atypical, is log home,dome homes, and Manufactured Home (you called mobile), and several others too long to note here.
Best to you.
