with the price of lumber and materials now, your house is worth at least a cool million. And I have no idea where or what it is.
Tue story: a few months ago, My cousin sold their house, bought another. The people they bought from were going to take the $ from selling the house and build a new house on another piece of property they owned. A few weeks later they came back and offered my cousin +$100K for their house, because it was going to cost them ~$300/sqft to build the house they had budgeted $200/sqft for.
