Wood is porous and holds moisture so give everything lots of dry time; if you stick directly to unfinished wood, moisture will accumulate in the wood over time and ruin the wallpaper. I usually do a gesso layer before I stick my paper down.
If you have access to cutting tools then consider designing it with tabs so that assembly is easier.
A lot of people sell laser cut houses on etsy so there is a market for it, but if that's a high priority for you then I'm not interested in discussing further. I don't really care to give advice for someone to just make a product to sell, especially if they're getting into a hobby space just to market to it. If you want any more advice about building your own house then that's fine. I'm not sure why some people join a hobby just to quickly jump to ways to profit from it. You can just make a thing to enjoy yourself.
