Q. I bought 12 acres of land 10 years ago for $83,000, built a house on a small part of that and have lived there for nine years. We are in the process of subdividing the land into 57 lots to sell. However, we have just been approached and offered $1.5 million for our land, excluding our house. Payment will be in 12 monthly installments. How much will we be looking at paying in capital gains tax?
