<p>All depends on where you live. Where I lived in NY, the largest house in the city (small city) was about 5,000 square feet. That was a mansion there but probably wouldn’t be considered one in other places.</p>
<p>6000+ or 8000+ or 10000+ square feet, depending on the quality of the interior.</p>
<p>High quality interior=6000+ would qualify as a mansion
Mediocre quality interior=8000+ would qualify as a mansion
Poor quality interior=10000+ would qualify</p>
<p>Where I live in TX nothing would be considered a mansion unless its 15000 sqft plus, I have about 5 or 6 friends with 10000sqft houses, mine is only about 3000 but the prices of houses is sooo much cheeper than anywhere else I’ve seen. It wouldn’t be unreasonalble to find a 7000-8000 sqft house for around a million buck. That being said about 5 miles from my house there is a 50,000 sqft mansion thats for sale for 42,000,000 big ones!!</p>
