You can get a decent piece of property for about $20,000 without a house on it. Then build it to your liking. I am thinking 50k to build a decent house. Depends where you are looking but I am looking in a beach town and the lots are small. My brother in law just bought a lot which is 360 sq meters (about 60x120) for 15K. I am trying to stick to a budget of about 30K, but you can buy complete houses for between 125-200K and some of them are amazing!
