Can You Get A Mortgage On A Home With A Well

Yes. When public water or sewer is not available, Fannie Mae expects community or private well and septic systems to serve the home.

Fannie Mae requires community or private well and septic facilities when public water and sewer are not available, and the owners must have the right to access them, which must stay viable on an ongoing basis. FHA accepts existing onsite systems when connecting to a public or community system is not feasible at a reasonable cost, as long as they work properly and meet local health department requirements.

FHA requires a well water test in certain cases, including new construction and when the appraiser reports a problem with the well or water. A third party must collect the sample, never the buyer or owner, and the report can be no more than 180 days old. The water quality must meet the rules of the local health authority. Planning repairs? See our FHA 203(k) renovation page.

For septic, the FHA appraiser looks for signs of failure and requires an inspection when they are readily observable. At least one VA program requires a septic inspection on new construction, when there is a sign of a problem, or in areas known for soil percolation problems. FHA does not accept water from springs, lakes, rivers, sand-point wells, artesian wells, or a mechanical chlorinator.

Wells And Septic Are Eligible

FHA, Fannie Mae, and at least one VA program finance homes with a private well or septic system when the program conditions are met.

Water Testing Rules

FHA requires a well test in cases like new construction or reported problems, and at least one VA program requires a well inspection on every VA loan type except IRRRLs.

Distance Rules

For an existing home on FHA, the well must be 50 feet from the septic tank, 100 feet from the drain field, and 10 feet from a property line next to a road or nonresidential land. Local rules win when they require more.

Shared Wells Can Work

FHA allows a shared well serving no more than four homes that cannot feasibly connect to public or community water, with a recorded agreement that binds future owners.

Septic Signs Of Failure

The FHA appraiser checks the septic system for signs of failure and requires an inspection if they are readily observable. If the septic is not enough and an off-site sewer is available, FHA requires connecting to it.

Repairs Can Be Financed

FHA 203(k) can pay for installing or repairing wells and septic systems, and at least one USDA repair program covers septic and water well work.
