Buying in Loudoun County

The market here moves quickly, but speed is not a substitute for due diligence. What follows is what happened to us—not a prediction of what will happen to you—and why we changed how we hire inspectors and specialists.

Our first home: what we missed

Our first purchase in Loudoun County came with an inspector the selling agent brought in. We did not know enough to question that arrangement.

What the inspection left out

He missed quite a bit. One of the strangest things looking back was that he told us he could not inspect certain areas because they were outside the scope of the inspection or because he could not legally move things in the home. He did not even go into the main house crawl space, which would have shown that there was no moisture barrier and that moisture routinely entered the home through the floors. He also did not see that the crawl space contained an old water heater with evidence of fire damage and possible electrical issues. When he told us he could not inspect those things, we accepted those limits instead of pausing and hiring someone who worked for us.

Two outbuildings that never got real scrutiny

There were two separate structures on the property, and neither was properly inspected. After we moved in, neighbors told us they had gone up quickly—likely to make the listing more attractive. One was marketed with an extra bedroom and full bath. The bath was DIY and never worked for us without major leaks. When we filed claims tied to that work, the carrier treated much of it as bad construction or workmanship and would not cover the damage. Your policy language will vary. Ours was a hard lesson to read the exclusions.

Main house: roof, HVAC, and an inspector who was wrong

In the main house, the roof was leaking. However, since it had not rained in some time the leak was not going to be obvious to us for months. The HVAC was not merely end-of-life—it included builder-grade and leftover job-site parts in places, with sections well past twenty years. The inspector called the HVAC an “excellent system.” That was false. Our first real HVAC maintenance visit—about six months after closing—called everything out. By then we were six months beyond the ability to ask for concessions.

What was in the inspection photos but never acted on

Flag anything odd in the inspection photos. Someone had stuffed paper towels into HVAC intake vents, likely to wipe dust and make the system look cleaner than it was for open houses. The inspector photographed the paper towels but did not remove them. Over time, a towel migrated through the ductwork, clogged the system, and nearly destroyed the furnace. When the HVAC crew pulled it out, I recognized it from the report photos. I was surprised that the inspector had not removed it, but he took the rule that he could not touch anything very seriously.

Decks and dirt

This one bothers me the most now. Many people build decks on dirt, and as a buyer you need to know when that deck went in. When decks are built directly on dirt or with beams on dirt, they can rot within a decade or less. That means you may step right through the wood one day. On our first home purchase, no one flagged this for us. No one flagged that the buildings themselves, even the one with the bathroom, were also built directly on dirt. This led to major moisture problems in all the buildings and eventually cost us thousands to have the deck ripped out.

After we closed

We renovated heavily and lived through more than five water leaks, including one that destroyed all the hardwood floors. The lesson is that the inspector could have seen signs of shoddy work and warned us. Instead, the house was described to us as a great home. The reality was far different. It was a beautiful home, but it was not a perfect home. Many issues that should have been the seller's responsibility became ours once we closed.

Do not let the realtor hire your inspector

Do not let the realtor hire your inspector. You want someone you chose, who answers to you, and who has time to open what needs opening.

The inspection we still compare everything to

On a later fixer-upper, we hired our own inspector. He cost about $500 and spent several hours on site. He produced a long, specific report and walked us through what we would be taking on. The house looked beautiful; he still gave us the unfiltered version.

Walking away—mostly for air quality

We did not buy that house almost entirely because of air-quality concerns for our kids (and kids we hoped to have). We had contacted the EPA with questions before we offered; but the inspection report itself gave us all the information that we needed to know that we actually felt comfortable offering if not for the air quality.

Roof, pool, and HVAC: hire specialists

A general home inspector is not a roofer, pool contractor, or HVAC technician. They will not inspect pools for plumbing issues or HVAC systems for cracked compressors.

Roof

A roofing inspector or reputable roofer can walk the roof, check flashing and penetrations, and tell you if you are near a replacement cycle. General inspectors will not do this in my experience.

Pool

Pools are great, but some have liners, buried plumbing, equipment, and sometimes sketchy outdoor electric that feeds the system. Pool repairs are expensive. A liner alone might cost more than $5,000, and a crack in the basin of a concrete pool is a major repair. You want a pool company for this.

HVAC

Furnaces, heat pumps, and condensers have finite life and expensive replacement costs, especially with multiple zones. You want an experienced HVAC technician to inspect the system and check for refrigerant leaks. You can sometimes smell those leaks, and they can point to expensive repairs. You also want to know when the system was installed so you can estimate when it may need to be replaced. Heat pumps that run for both air conditioning and heat may only last around 10 years.

Septic

Most buyers already know to bring in a septic company to inspect and pump tanks. I am including septic here because the same logic should apply to the other major systems above.

DIY work, bad construction, and insurance

Look for signs of bad construction. It will not be covered by insurance. Carriers often deny or sharply limit claims they attribute to faulty workmanship, long-term leaks, or neglected maintenance. Language depends on your carrier and state—read your policy or ask your agent—but assume you may be the one paying when construction is the root cause.

Wood on soil

Decks, posts, or outbuildings sitting on dirt will absolutely trap moisture. Failures can show up on the order of years, not decades.

DIY plumbing

Odd routing, mixed materials, and hidden joints can leak slowly into framing. Wood will rot, and you usually will not see it until the damage is widespread.

Electrical red flags

Panels that look hacked, breakers that do not match the labels, crowded neutrals or double-tapping, extension cords used as permanent wiring, or pond pumps tied into sketchy boxes—all reasons to get a licensed electrician involved before you rely on listing photos.

Rushed cosmetic cover-ups and closing-room pressure

Fresh paint, new caulk, or quick patches can hide stains or soft wood until after closing. Probe, smell for mildew, and read the inspection report line by line—especially in basements, under sinks, and along exterior trim.

When we tried to hold the seller to real repairs

I was not completely unprepared: I asked that rot I could see be replaced by a certified home-improvement contractor. The sellers had a friend paint over it instead. At closing they threatened to sue if we backed out. Your contract is your safest leverage—get what you need in writing while you still have negotiating room. In a competitive market you may not win every concession, and some risk will still land on you as the new owner; but the goal is to limit your risks as much as possible.

Visit the town and price major replacements

Before you offer, visit the neighborhood outside the single showing window: traffic is a huge consideration, so think of how loud it will be in the backyard or your commute, and also what services are local. Then do local pricing homework—what would a full roof replacement and a full HVAC replacement (or two zones) cost with reputable contractors in that zip code, not a national average from an article. If the roof or HVAC failed tomorrow, could you absorb it without wrecking your budget? If not, your offer or contingencies need to reflect that risk.

Our second home: Frederick County and another agent-hired inspector

After the good fixer-upper inspection, we still slipped: on what became our second home in Frederick County, the realtor hired the inspector and I did not catch it in time. The report was light—a few cosmetic notes around things like the fridge and otherwise “a great house.”

What failed early and what it cost

We over-offered in a competitive market; with a proper inspection and specialists we likely could have negotiated some of that back—the fixes were not small. The deck failed (wood on dirt, rotted). HVAC zones failed within about two years—tens of thousands of dollars each time, and urgent because humidity and equipment failure can damage the house and because carriers may have expectations about how you maintain systems. The pool liner was failing and pool plumbing was cracked. A small pond had DIY electrical tied into the pool equipment in an unsafe way. Moving in and immediately absorbing roughly $30,000 in hits—and needing two HVAC replacements right away to prevent further damage—is not a position you want to be in.

What we budget for now in Virginia

We shop our own inspectors and specialists even when it adds hundreds or a couple thousand dollars during the due-diligence window after we are under contract. That is usually when pressure eases: you have an accepted offer and can breathe while the right people dig in. The upside is peace of mind, leverage for repairs and credits, or permission to walk. None of this replaces your contract, your agent, or local law; it is what we wish someone had spelled out before our first offer.

Realtors are hit or miss

We have had some great agents. One agent we worked with did an excellent job marketing homes. The lesson we learned is that the experience is hit or miss. Some realtors pay close attention to details, and others focus too much on getting to closing.

Lenders are also hit or miss

Not everything our realtors did was bad - in certain ways they were excellent. One of those ways with with our lender. We have friends that are real estate agents and they advised us of a specific lender to use. So we reached out and got a quote and WOW. The closing costs were insane. When our actual realtor heard he went and got his lender to give us a quote and it was a better rate, same term, and like one quarter of the closing costs.

Frequently Asked Questions

Is Loudoun County a competitive housing market?

Yes. The rush usually peaks before your offer is accepted. Once you are under contract, you have a due-diligence window—use it to hire your own inspector and specialists without skipping steps.

Should the buyer hire the home inspector?

Yes. Do not let the agent hire the inspector unchecked. When the agent hired ours, the inspection was shallow and expensive problems showed up after closing. When we hired our own on a fixer-upper, we got a four-hour, detailed report and walked away when the risk was too high.

Do we need separate roof, pool, and HVAC inspections?

A general inspection is a start, not a substitute for tradespeople who see those failures every week. A general inspector may not find bad pool liners or cracked coolant lines, and both can point to thousands of dollars in repairs.
