Identify the permit jurisdiction before searching. Outside Rockville and Gaithersburg, Montgomery County's Department of Permitting Services is generally the starting point for residential building and electrical records. Those cities issue their own permits, and plumbing may run through WSSC or the applicable city authority. Search additions, decks, finished basements, accessory structures, HVAC changes, wells, septic systems, and historic-property work in the correct system. Keep permit numbers, inspection results, plans, contractor invoices, and photographs together. If a record is unclear, ask what remains open before treating a portal entry as final approval.
Water and land records deserve a separate pass. County guidance explains that many activities within a regulated floodplain district need review, and rural or low-density properties may have private wells or onsite sewage systems. Gather any floodplain study, elevation information, septic inspection, well record, drainage correspondence, insurance claim, and repair invoice. A mapped floodplain does not prove that water entered the house, and a working septic system does not answer whether its permit file matches the current use. Describe what is known and keep the unknowns visible.
Then compare the work each sale route asks of you. A listing may involve permit closeout, private-system inspections, cleanup, contractor scheduling, repeated access, and continued taxes, insurance, utilities, and loan payments. A written as-is proposal may reduce some of that preparation, but review the price, inspections, cancellation rights, title conditions, costs you would pay, closing date, and possession terms. If the property is inherited, rented, or owned by several people, confirm authority and access early. The practical choice is the one whose cost, paperwork, and timing fit what you can realistically manage.
