A reasonably low-level character can get to Prantz quite easily through existing housing portals made available by various organizations.
Houses cannot be "moved" per se - the door that leads to the interior of the house can be changed to a different door, but it's not a trivial thing to do. Building a "new" house where there wasn't one before requires a module update, would be
extremely expensive, and may simply not be granted because of the hassle entailed in doing so.
Purchasing the farmhouse in the Hempstead fields is... well, I won't say "impossible", but we'll say that the bar to doing so would likely be a CDQ at
least, and being approved for such a CDQ may simply not happen. If it turns out to be possible, it would be significantly more costly than any house currently on the market.
Best bet as to finding houses is to go to every real estate office you can find. Given the desirability of housing, it can be scarce, but there's usually a place or two up for sale.
So, while you may chafe under Rael's rule, it may be the way to go, at least for now.
