One must also ask in addition to your pertinent questions, can the market bear putting the same price on a tiny house as it can with a large house? It's about perceived value. It's the same as anything "wedding". The price will go up just because the word "wedding" is there: wedding photography, wedding invitations, wedding catering.

With tiny houses, you're going to get the opposite effect of the price being lower because if of the "tiny" aspect.
