No, its a proven fact a good deal of the forum wants house-building.
Even going back to New Vegas people wanted to build there own house as a money sink.
I just hope that Hearthfire isn't plagued by the infamous Dawnguard bug, the one where vampires enter cities and go on an NPC killing spree. It would be annoying if several master vampires entered your home and killed your new family that you just spent hours adopting.
That isn't a bug its a feature, and incredibly annoying one I imagine but intentional. Now DLC can't interact with one another directly, unless you can build the house in a town where the vampire attacks already happen you wouldn't see vampires around your house. Dragons on the other hand are much more likely to be an issue.
