Water and septic in Mohawk Valley
Assume private well and on-site septic unless you are told otherwise. That means the well log, the depth and flow rate, a current water test, and the county septic permit record all belong on your list before contingencies come off. Oregon also requires a seller to test a domestic well for arsenic, nitrates, and total coliform once an offer is accepted, so ask for those results. Septic permits for this area are held by Lane County, and the permitted capacity is tied to bedroom count, which matters if you plan to add on later.
What you can actually build in Mohawk Valley
Zoning does more work here than acreage does. Farm and forest zones in Lane County exist to keep working land working, and they put real limits on new dwellings, second homes for family, and some business uses. A dwelling right is verified through a land use application, not inferred from how many acres are on the listing. If your plan involves building anything, get the answer from Lane County planning in writing before your contingencies expire. Farm and forest zoning with real dwelling limits.
Floodplain and water, Mohawk Valley specifics
Water is part of the appeal here and part of the diligence. Check the FEMA maps for any parcel near a river, creek, or reservoir, because floodplain status affects insurance cost and sometimes what you can build. On the Corps reservoirs, levels are managed seasonally and drawn down for flood storage, so the shoreline you see in June is not the shoreline in October. If a water view or water access is part of why you want the property, look at it in two different seasons.
Insurance is an early question in Mohawk Valley
Wildfire risk affects insurance availability and price in this part of the county, and it is the item most likely to surprise a buyer late. Get a written quote during your inspection period rather than assuming coverage will be routine. It is also worth asking about defensible space around the structures, since it affects both your premium and your risk.
What Mohawk Valley is actually like to own in
This is genuinely rural property, not a subdivision with a view. You take on your own water and waste, longer drives for everything, and weather that occasionally takes the power out. In exchange you get room, quiet, and neighbors who show up with equipment when you need it. Most people who move out here would not go back. The ones who struggle are almost always the ones nobody told in advance.
