That's what I am saying, they are just two people living in it, for me it feels they want to feel like millionaires and when they realize the cost of maintenance and other expenses for it, they might end up losing everything else they have. They could buy a super real nice house with half their money and save the rest for healthcare, savings, and other investments. I learned one should never put all their eggs on one basket.
In almost every part of North Carolina, a 4,200 square foot house can be purchased for less than $500,000. They very well might have done exactly what you said - bought "a super real nice house with half their money".
