What the Article Covers

Three Systems That Shape Every Deal

Septic Systems: The Biggest Unknown

In many homes around Medina, septic systems are common and often misunderstood. Most are underground, age is not always obvious, and they can function fine right up until they do not.

Minor repair$2,000 - $5,000
Full replacement$15,000 - $25,000+
Pro Tip: Always include a contingency to pump the tank, inspect the system, and uncover the distribution box.

Wells: Your Water Source Matters

Private wells are common in rural and semi-rural parts of Western NY. Unlike public water, the homeowner is responsible for quality, maintenance, and equipment.

  • Water test results (bacteria and nitrate levels)
  • Water pressure and flow rate
  • Age and condition of pump, pressure tank, and filtration
Clean, reliable water builds buyer confidence. Questionable water creates hesitation—and renegotiation.

Inspections: Required vs. Smart

In New York State, septic and well inspections are not required by law. They are negotiated in the contract, requested by the buyer, and approved or denied by the seller.

  • Buyers: request these inspections specifically in the contract
  • Sellers: get ahead by testing before listing
  • Smoother inspections mean smoother closings
Key point: If you don’t ask, you likely won’t get it. Don’t assume it’s included.

Guidance for Buyers and Sellers

For Buyers

Protect Yourself Before You Commit

Know what you’re buying and what it’s going to cost you to own it.

  • Don’t assume systems are functioning properly
  • Don’t skip inspections just to win
  • Understand cost ranges before contract
  • Request septic pump + inspection + distribution box
  • Ask for well test results + equipment details

For Sellers

Get Ahead of the Problem

Pre-list inspections remove uncertainty and put you in control.

  • Schedule a pre-list septic inspection
  • Pump the tank and document condition
  • Run a well water test and keep results ready
  • Fix small issues before buyers use leverage
  • Documentation = stronger, cleaner offers
This often leads to stronger offers and fewer surprises.
