A Practical Mechanical Checklist Before Closing on a Distressed Property

Why the Mechanicals Deserve the First Look

Cosmetic problems on a distressed property are honest problems. Peeling paint, a dated kitchen, worn carpet — these announce themselves at the showing and can be priced from a photograph with reasonable accuracy. Mechanical systems behave differently. A furnace that fires on a mild afternoon tells you almost nothing about the condition of its heat exchanger. An electrical panel can look tidy while hiding a service that cannot carry modern loads. A drain that runs clear under low flow may still be half closed by decades of buildup. Investors who budget from the surface inward tend to meet the expensive surprises after closing, when the leverage is gone and the contractors are already on site.

Allen Spearman makes that case in a Realty Times article on why mechanical systems make or break a real estate rehab. His position, as the piece presents it, is that electrical panels, heating equipment, ductwork, and plumbing decide whether a project makes money, and that cosmetic budgets frequently mislead investors into the wrong conclusion. The article works through older housing stock — Philadelphia rowhomes among them — and the specific traps that come with it: undersized electrical service, HVAC decisions in buildings that have no ductwork at all, plumbing and drain due diligence, permits, and the discipline of pricing mechanical work before an offer goes in rather than after.

The background behind that argument is on the Allen Spearman About page. He is a Philadelphia business owner whose work spans HVAC and electrical contracting, property development, and commercial services. He is a master electrician and an HVAC technician and installer, and he owns and runs All HVAC and Electrical, LLC, founded in 2017, along with Spearman Properties, founded in 2004. Through Spearman Properties he has rehabilitated more than 100 properties in the region. Before any of that, he founded Restaurant Cleaning Services in 1998 after graduating from college, serving diners and restaurants in greater Philadelphia, and he earned a degree from Penn State University.

Electrical Service and Panel Capacity

Start at the meter and work backward into the house. The questions are simple even when the answers are not: what is the service amperage, what condition is the panel in, and what does the branch wiring look like once you get past the finished basement ceiling? In older housing stock you will encounter 60-amp services, fuse boxes, cloth-covered conductors, knob-and-tube runs buried in plaster, and receptacles with no equipment ground. You will also find double-tapped breakers, rust or water staining inside the enclosure, and panels from manufacturers whose breakers are difficult or impossible to source safely. Each of those is a line item, and some of them cascade.

A service upgrade is rarely just a panel swap. Bringing an older house up to a modern service can pull in a new meter, a new mast, a grounding electrode system, and repairs to whatever the electrician finds behind the drywall once the old enclosure comes off. Budget the cascade, not the panel. This is also the moment to think about load: adding central air, a heat pump, a tankless water heater, or an electric dryer to a house with marginal capacity can turn a small electrical allowance into a full service change.

Heating, Cooling, and the Ductwork Question

Philadelphia rowhomes and similar older buildings often have no ductwork whatsoever. Heat comes from radiators fed by a boiler, or from a gravity system that has been patched together over several decades, and cooling comes from window units. That is not a deal-breaker, but it does mean the mechanical budget depends on a design decision rather than a replacement decision. Ductless mini-splits, high-velocity systems that run through small chases, and conventional ductwork tucked into soffits and closets all solve the same problem at very different price points and with very different consequences for the floor plan.

Where ducts do exist, their condition matters as much as the equipment attached to them. Leaky, undersized, or disconnected duct runs can waste a large share of the capacity you are paying for, and sealing them is often cheaper than replacing the system. It is worth noting that he was the state’s first certified Aeroseal agent for duct sealing, work that sits squarely on the boundary between HVAC and building envelope. Whatever the approach, verify venting and combustion air before you commit. An orphaned water heater in a sealed mechanical closet or a chimney serving a boiler that no longer needs it are the kinds of details that fail inspection, and worse.

Plumbing, Drains, and Water Risk

Supply piping tells you a lot about how a house has been maintained. Galvanized steel that has narrowed internally, polybutylene, or a patchwork of copper and plastic spliced together over fifty years all point to future work. Check the main shutoff, test water pressure, look for corrosion at fittings and valve bodies, and note the age of the water heater. Slow leaks under sinks and behind walls rarely announce themselves during a fifteen-minute walkthrough, so look at ceilings below bathrooms and around the water heater pan.

Drains deserve their own pass. Run water at every fixture, including the laundry standpipe and any floor drain, and watch how quickly it clears. Cast iron waste lines in older basements can be scaled down to a fraction of their original diameter, and a sewer lateral may be cracked, root-intruded, or made of clay tile that has shifted. If there is any doubt, scope the line. A camera inspection is a small expense against the cost of excavating a front yard or replacing a basement floor.

Permits, Scope, and Pricing Before the Offer

Permits are the part of due diligence that investors most often skip, and they are the easiest thing for a seller to leave ambiguous. Ask specifically about open permits and unpermitted finished space. A basement bathroom or a converted porch that was never inspected can become your problem the moment you pull a permit for anything else, because the inspector will want to see the whole scope brought into compliance. Check what the local authority requires for a service change, a boiler replacement, or a new HVAC system, and build inspection time into the schedule rather than assuming it will fit.

The other discipline is pricing the mechanical work before the offer, not after. A written scope with model numbers, quantities, and allowances is worth far more than a verbal range, and it gives you a defensible basis for a reduced offer or a walk-away number. Investors who want that scope built by someone who has worked both trades can reach out through the Allen Spearman contact page, which is set up for project inquiries. Even if you use your own contractors, going through the exercise before the property is under contract keeps you from negotiating against yourself later.

A Walkthrough Sequence That Works

Order matters when you are walking a distressed property with a limited amount of daylight. Move from the largest systems down to the details, and photograph everything with the panel covers off where it is safe to do so. A workable sequence looks like this:

• Service and panel: amperage, brand, breaker types, grounding and bonding, meter and mast condition.
• Branch wiring: visible knob-and-tube, cloth-covered conductors, ungrounded receptacles, missing GFCI protection in kitchens and baths.
• Heat source: equipment age, model and serial numbers, venting and chimney, combustion air, and whether it actually produces heat.
• Cooling and distribution: existing duct size and condition, return paths, insulation, or the complete absence of ducts.
• Plumbing: supply material, main shutoff, water pressure, water heater age, corrosion at visible fittings.
• Drains: flow test at every fixture, accessible cleanouts, sewer lateral scope if anything looks questionable.
• Permits: open permits, unpermitted finished space, and any work that will require inspection before occupancy.

Two habits make that list pay off. The first is converting every observation into a dollar figure on the same day, while the details are still fresh — a vague note that the panel “needs work” will not survive contact with a spreadsheet. The second is treating the process as ongoing education rather than a one-time exercise. His public Allen Spearman profile is one place to follow the work as it develops, and regional contractors and investors also connect through his Allen Spearman Facebook profile. Neither substitute for a proper inspection, but both help you calibrate what a realistic mechanical budget looks like in this market.

Closing on a distressed property is ultimately a bet on numbers you cannot fully see. The mechanical checklist is how you shorten the list of unknowns before the bet is placed — service capacity, heat and cooling strategy, water and waste, permits, and a priced scope in hand. Do that work first, and the cosmetic decisions get much easier to make, because you already know what the house can afford.
