How much does it cost to build a subdivision of houses on a large plot of land?
Let's think like a real estate developer. First you need to check with the zoning commission the restrictions for the area. Let's say that the plot is actually suitable for 10 homes. You buy the land. You also need to finance the build itself. If you don't have enough cash you need to acquire financing from banks and perhaps from other sources as well, because banks won't loan you the entire amount.  Next you need to divide the plot into 10 pieces, making sure that each piece has driveway access to the street and plan access to utilities (water/sewer/electricity/broadband/phone lines). Plan the size and position of each house. Get building approval. This is a process that can take some time, especially if they have follow-up questions. Get a builder to build the houses, including ground work and preparation for utilities. Get approval for the finished houses. A building inspector will check that the houses follow the permission and all laws and regulations that apply. This step can entail time and added cost.  Get a real estate agent to sell the new homes. Often, the selling process starts in the planning phase and early buyers are able to influence both the layout of the house and the finish. Your cost estimate included a profit of 140k for each house. From that a builder needs to subtract financing costs, real estate agent costs, any costs that you forgot to factor in, budget overdrafts, contingency costs, and salaries for your staff and yourself. I estimate the project time to 1.5-2 years. So, we have an $8M project with a gross profit of $1.4M (not including all costs). Net profit probably just a few hundred thousand. Or less.  Real estate developers with local knowledge would be able to make a much more accurate estimate on both time and cost. My guess is that they have, and since the plot hasn't sold in a while, either the price is at the upper end of what makes a profitable project or there are other restrictions that limit the number/size of homes that can be built on it.
