Great FallsLook closer. Live informed.

With a custom home or a larger parcel, the land and the systems deserve as much attention as the rooms. Build your comparison around the whole property.

01

Begin at the property line

Request a current survey or discuss whether one is needed. Review recorded easements, access, setbacks and the relationship between the house, driveway and neighboring land. A lawn or fence is not proof of a legal boundary. Confirm a proposed pool, addition or outbuilding with the appropriate professionals before treating it as feasible.

02

Water, septic and drainage

Determine which utility systems serve the particular address. Where a private well or septic system is present, obtain its records and use qualified specialists to assess condition, capacity and maintenance. Walk the site for grading and drainage questions. Consult Fairfax County’s onsite sewage and well-water resources for the applicable requirements.

03

Custom construction and operating costs

Large or highly customized homes can have multiple mechanical zones, extensive exterior materials and specialty equipment. Ask for service records and price out upkeep before committing to the property. Distinguish a cosmetic update from replacement of an aging system.

04

Find meaningful comparisons

A nearby sale may have a different lot, age, layout or degree of renovation. Review each comparison rather than averaging prices across a broad area. Unique amenities can be valuable for your own use without returning their original construction cost at resale.

05

Plan a deliberate showing

Leave enough time to inspect outbuildings, access and exterior conditions. Test the route to your daily destinations. If you are selling, assemble records early so buyers can understand the property’s features and maintenance responsibilities.

Bring these questions to your search.

  • Which utilities and private systems serve the home?
  • What recorded restrictions affect the land?
  • What specialist inspections are appropriate?
