I just sold a 13.6 acre lot in Jefferson, MD. There are some land listings available. One I know of in Potomac is about 2 acres and is priced at around $1,000,000. But other areas have different prices. If you give me a call, I would be happy to talk about your goals and help you devise a strategy to achieve them. My services are generally free to buyers, so there is no risk on your part. Let me know if I can help and we can get you the information you are looking for right away.

The first step is to work with a realtor who has real-time access to active land/lot properties for sale. I can email you land/lot listings once you contact me.
Some sites don't include unimproved lots, so you should have an agent setup a search for you. Here's a link of all available lots (sorted by lot size) in Potomac with at least 2 acres:
Hope that helps. Building is quite an endeavor. Finding and buying the right lot is just the first step of many. This process can take years, and obtaining financing is more of a challenge now than it was several years ago. Good luck.
