Ask a question about real estate and lot size in Alaska?
Someone who lives in Alaska or sell real estate in Alaska could help with this question. I live in Florida, but I am considering moving to Alaska (well – sounds weird, but let's continue.) I'm looking at houses on realtor.com in the vicinity Anchorage. It seems like even in cities like Eagle River and Willow, the lot size is small. I currently live on 1 acre and all lots in my neighborhood are 1 hectare. A quarter-acre lot is the smallest we got here. But the properties in the suburbs of Alaska have much much smaller – 1/10th of an acre – something thus. So – I think I'm missing something. There must be good reason for it. Or maybe I'm just looking in the wrong place. Because I have little / no knowledge real property in Alaska, I'm looking for some help. Thank you!
In Anchorage and the immediate area surrounding the lot size is so small, because the city literally has no other place to build. The area is surrounded by mountains and water so that the only way they can build more homes to reduce the lot size.
