$142 is the average. $75 per square foot is the low, and $234 is the high. I ran a market analysis for homes built in 2017 and generated some averages.
If you are thinking about building a home, be careful. You must know which builders are financially strong, and which ones are running on thin ice. I recently gave my opinion to a customer on a builder I had concerns about. They decided to go with another recommendation. 1 month later the builder I was concerned about went under, and now are facing a dozen angry customers with homes that will not be finished, and contractors looking at them for payment. I referred a better builder, and the customer is happy, and thankful for my experience. One mistake can put you at risk of losing money and being stuck with an unfinished home. And if you engage them unrepresented, you better under stand the fine details of our Florida contracts, or you may find yourself at a big disadvantage.
Most customers don't realize that they can have me and Re/Max represent them for free. Builders have a commission built in to their costs, and plan to pay a Buyer's agent. You may think they will give you a better deal if you go direct, but really, they will just keep the entire commission and still give you the same deal they offer everyone. They will then work in the best interest of the builder. They can not require that you use their agent, lender, or insurance company to get a better deal. They can suggest it, but not require it. That would be an ethics violation.
Anyone wanting to build a home, call me. I will help you negotiate a better price, review your contracts, explain construction loans (I wrote hundreds of construction loans as a lender for 13 years), and protect you while you pay me nothing. It is foolish not to me work for you at no cost to you. My customers always win, and never get taken advantage of.
