I know you're trying to keep costs down, but unfinished trim work and/or exposed plywood (especially on the $9k model) makes everything look incredibly cheap. Take a look at how similarly-priced RVs handle their interiors for comparison.
For $29k you can get something that you can drive and is generally furnished better (in a lot of municipalities these tiny houses need to be on wheels to skirt code violations anyway).
