I don't think your house is representative of the US housing market. I once lived in an apartment in a 17th century masonry building in Alsace, and it didn't seem to give my landlord nearly as much grief as my parents' 1960s-era suburban home in Houston did to them.

Sure, just mentioning that it is possible to build a house that lasts a long time. There isn’t some law of nature that prevents it.

True, but houses like that are far more expensive to build today. I'm not sure you could "flip" a new home built with traditional masonry since it would require a larger upfront investment. (Edit to add: the normal American usage of "flip" (buying a degraded property, fixing it up, and reselling) is also not really applicable to houses in move-in-ready condition.)

The original construction costs will probably have been recouped after 370 years of continuous occupancy, though. :)
