It doesn't help when they can go to Trade-a-plane and find asking
prices up in the stratosphere for similar planes and with my luck
they'd find one that was a prize winner at Oshkosh worth twice mine.

I'm building a Glasair 3 myself, and tactic I've seen used by a lot of
homebuilders is to not name the aircraft what the kit maker calls it.
Being the builder, and building 51% or more of it, you are free to
name it anything you want to call it. Calling it a Glasair just helps
the state out in figuring out what it's worth. I guess I'm lucky in
that in my state, they don't actually go out and inspect a homebuilt
at the airport, Mich. sounds a lot more agressive in that area. But we
pay a yearly personal property tax on cars and planes, boats, ect..
And I've heard is the 3rd highest in the country for PPT. (SC).
Homebuilts aren't so easy to set a value on, and states that go after
them for tax money are especially greedy. Some builders never plan to
sell them for fear of liability, so in those cases, the resale is hard
to put a value on.
