Assessing Plumbing/water/sewer Risks for Older Home Rental Properties

Assessing Plumbing/water/sewer Risks for Older Home Rental Properties

Buffalo Grove, IL · Member since 2017 · 54 posts · 39 votes

I’m exploring rental properties in Milwaukee, Racine, Northwest Indiana, or Jackson, Tennessee, but I’m consistently stopped by the prospect of aging plumbing. Many of these homes still rely on galvanized interior pipes or retain a lead service line up to the house’s entry point, yet standard inspections rarely include a video scope of the water, sewer, or supply lines. My concern is that I could face an unexpected repair bill running into the thousands—something I want to avoid without becoming so selective that I miss out on solid deals.

Are lead water lines that terminate upon entry into the house really an issue (not throughout the house, just into the houses entry point)? If low water pressure suggests a blockage or corrosion, is it typically a straightforward fix—scope the line, replace the offending section, and move on at modest cost—or does it more often signal hidden piping issues behind walls that demand full repipes costing several thousand dollars? Likewise, what’s the likelihood that supply or sewer mains will require dedicated camera inspections—and that those inspections will reveal defects leading to major outlays? I understand conditions vary by locale; are these worst-case scenarios common enough to justify my caution, or am I overthinking what often proves to be manageable issues?

Living in Milwaukee myself, I feel that it is hard to judge what you will find with Milwaukee pipes. But I also feel like it is one of many things that could be a problem or could not be a problem that unless you are willing to pay to get it checked out ahead of time is going to be a gamble. But, I think generally, it is a risk you have to take. If a few thousand dollars more than you were hoping is going to tank the deal, it might not be a good enough deal in the first place. Because even if you get everything checked out, there is still always a chance a pipe will go, or an appliance will crap out, or some other endless list of unforeseeable problem will arise. You have to plan for what you can and give a little cushion for what you can't. But if you suspect something, then go ahead and pay for the inspection of it. Better safe than sorry.

    Nothing lasts forever. If you are buying 60-120 year old homes in Milwaukee you have to get comfortable with the fact that you will have to spend money on capex. Galvanized plumbing has a life expectancy of 40-60 years. On average, a house needs a full rehab every 30-50 years - everything from roof to bathrooms. Our approach is a full rehab which includes all plumbing lines, kitchens, bathrooms, flooring, doors, windows, often also roof, sometimes driveway, removing old trees etc - you can do it up front and all at once and then have a nice property to rent or you can piecemeal it over time. Thats why you can't afford to buy properties in areas that do not appreciate well - you need that gain to offset capex, otherwise you'll spend all of your cash flow and then some..

    You can scope sewer lines, but surprisingly, that is NOT industry standard in Milwaukee, so it will be an automatic red flag when you are making an offer on a competitive listing. And you can't scope supply lines, you just replace them. Lead supply lines are common on the East side, you can find more information on the city water website what that really means and what will be done about it.

    @Nicholas A.

    Great question—and you're not overthinking it. Lead service lines (even if only up to the house) can still pose long-term liability and may be flagged during resale or insurance underwriting. Low water pressure often points to corrosion in galvanized pipes, which can mean isolated fixes or a full repipe—it depends on accessibility and extent. Sewer line issues are common in older homes and a camera inspection is absolutely worth it; surprises here can be costly. Your caution is justified, but with proper due diligence (scope inspections, city line records, repair estimates), many of these risks are manageable and even negotiable in your offer.
