Buying or Selling a home with a private Well?

In the majority of real estate transactions, it is necessary to conduct a Coliform and E-Coli test to assess the quality of the water supply.
Additionally, they may also require lead, nitrates, and nitrites! To avoid any delays in your loan closing, ensure that you complete the necessary water testing in advance. Please consult your underwriter for the specific requirements of your loan, and feel free to reach out to us at 636.583.9288 if you have any questions.

🏠 Buying or Selling a Home with a Private Well? Read This! 💧

If you’re on a private well, keep in mind that different loans have different water testing requirements. FHA, VA, USDA, and conventional loans may all ask for specific tests before you can close.

We’ve seen it happen too many times—everything is ready for closing, and then the underwriter waits until the last minute to request a water test… which can delay your closing date.

At Franklin County Lab, we’re here to help you avoid the stress. We can get your testing done quickly so you stay on track.
