Don't forget to get a survey done. Before you purchase the lot, ask to see a recent survey or have one done to validate property lines and make sure other neighbours aren't already encroaching on the lot with access roads, fencing, or structures.
Don't let neighbours know of your plans. Don't get too friendly just yet. If the land you plan to build on has been enjoyed by nearby property owners for the view, for parking, or for recreation, your plans to build may be met with resistance.
Don't assume you can have property rezoned. Make sure you know the property zoning regulations for the property. If you are in a rural area and plan to have chickens or horses, make sure you know the property zoning regulations for the property. If you are in a rural area and plan to have chickens or horses, make sure that is permitted. Be wary of sellers who tell you that you can subdivide the land or build two homes on one lot, as this may not be the case.
Don't rely on a drive-by. You need to walk the property, no matter the size or your plans for its use. If you are buying multiple acres, don't assume that the topography is consistent throughout with no hidden problems. Things to check for include flood-prone areas, environmentally protected-animal dwellings, trash deposits and neighbours that are involved in activities that may affect your enjoyment of the property, such as dog kennels or shooting ranges.
