Many here have given you some good advice. You would think that buying a lot would be a simple issue. But, alas, you need to exercise caution and consult with an attorney that specializes in real estate matters. Discuss with your attorney your intended use of the property as zoning can restrict what you intend to do or build. You attorney will also make sure the title is free of liens, encroachments and encumbrances. For example, does the neighbor's garage sit 2 feet onto your property. Are fences properly placed. Your attorney may also want to order a survey to confirm these issues.
Make sure you physically inspect the property. A while back I had a client come to me after he had bought a city lot in Chicago site unseen in an auction. When he actually took a look at the lot he discovered that it had been used for some time as a dumping ground for several dozen junk cars. Unfortunately, he bore the responsibility for clearing the lot. Also, check to see if there have been other types of dumping. Be wary of unmarked barels or industrial or construction waste. These may be signs that the property is environmentally contaminated.
As suggested by others here, once you own the lot you become the responsible party for securing the lot, keeping the grass mowed, keeping it free of debris and for preventing against dangerous conditions. These are just some of the considerations that you should take into account before buying. Hope all work out well for you.
