Most first-time buyers spend months preparing for closing day, but the 90 days that follow can be the most financially precarious. According to Armadillo, a home warranty company that leverages modern claims data, the highest volume of system failures—including HVAC, plumbing, and water heater issues—occurs within the first three months after a buyer moves in. This timing is not coincidental, and for buyers who have just depleted their savings on a down payment, it can be genuinely damaging.
When a home is sold, all of its systems are inherited by the new owner. Many of these systems may have sat unused for months, especially if the property was vacant during the sale. An HVAC unit not tested under real conditions, a water heater that sat idle, or plumbing that hasn't been fully pressurized can fail quickly once a new household begins using them at full capacity. Matan Slagter, founder and CEO of Armadillo, notes that their data shows plumbing, water, and electrical issues cluster around move-in at rates higher than any other point in a homeowner's tenure, a reality many buyers do not expect.
The financial impact is compounded by the timing. A buyer who stretched to cover a down payment is also facing their first mortgage payment, utility setup, and moving costs. An HVAC replacement that can exceed $10,000, or a water heater failure costing $2,000 or more, is not a manageable surprise in that window.
Home inspections are a standard part of the buying process, but they have limitations. An inspector checking an HVAC system in summer cannot meaningfully test the heating side, and one in winter faces the same issue with cooling. Inspectors can note what they see, but they cannot simulate a year of wear. Slagter explains that Armadillo's position is that if something wasn't flagged in the inspection report and fails after move-in, the reasonable assumption is that the buyer could not have known, and the breakdown is covered. However, disputes often arise when buyers fail to read their inspection reports carefully, file claims on documented issues, and are surprised when coverage is denied. The takeaway for buyers is to read the full inspection report before closing, not just the summary, and ensure that any flagged issues are either repaired by the seller or documented as addressed before a home warranty kicks in.
According to Armadillo's claims data, the systems that fail most often in the first months after purchase are HVAC systems, water heaters, and plumbing. HVAC failures often occur when buyers move in during one season and don't test the opposite function until weather forces it—for example, closing in June and discovering the heat doesn't work in November. Water heaters degrade over time and are often near end-of-life in older homes; while inspectors can note age, age alone doesn't disqualify coverage if the unit was functional at inspection. Plumbing issues can range from slow leaks not visible at inspection to pipes that fail under the load of a new, fully occupied household.
A home warranty doesn't prevent breakdowns, but it removes the financial shock from the timing. Buyers with coverage in place before moving in can file a claim, choose whether to use Armadillo's network of vetted technicians or bring their own, and resolve the issue without depleting remaining savings. Armadillo is one of the few companies that offers both options upfront, a model detailed at armadillo.one. This customer-choice technician model means buyers who already have a trusted plumber or HVAC tech aren't forced to use a stranger from a dispatch network. This flexibility is one reason the company carries a 4.7-star Google rating in an industry that averages two to three stars.
For first-time buyers, the post-closing window is when a home warranty earns its value most clearly. The math is straightforward: a few hundred dollars in annual coverage versus a potential five-figure repair bill at a moment when there is little cash to absorb it. As the data from Armadillo shows, the first 90 days are a critical period that buyers should plan for just as meticulously as the closing itself.
