I guess those huge houses have occupants. I don't like people building huge houses without future consideration.
Once the children decide to be on their own then the house becomes obsolete and relatively quiet
Most time the occupant even find it scaring to live in it alone with less companion around
I am always a advocate of maybe a three bed room house and wide compound.
Here big houses show off your wealth and prestige...If I was worth a lot of money no one would know. I'd live in a small house with a huge garden and drive my old car around...hehehe
Considering those big house, don't they pay taxes on it?
Unlike my country here where we don't pay tax on houses.
Another reason owning property in the US is we really don't own anything we have to pay taxes on... good observation @fadijio9
