Most agents can show you a house. Siamak Kalhor can tell you whether the land under it will let you build the next one. A licensed California Realtor (CA DRE #00908799), Siamak leads the Napa Valley practice of K2 Investment, Inc. — and he brings something to the table most Napa agents cannot: he lives in the valley, and he has personally built houses here.
That difference matters because in Napa County, the house is rarely the hard part. The land is. Hillside ordinances, the Agricultural Preserve, well yield and water rights, septic feasibility, fire-hazard mapping, access easements and the county permit process decide what a parcel is actually worth — and a buyer who learns those answers after closing has paid tuition instead of a price. Siamak evaluates land the way a builder does, because he has been the builder: soils before square footage, water before views, entitlement before emotion.
What he works on
Land to develop. Raw and improved parcels for buyers who intend to build — feasibility-first analysis of zoning, water, septic, access and fire mapping, drawing on the county process he has been through personally. K2's free Parcel Finder tool, which reads county parcel, zoning, FEMA flood and fire-hazard layers for any California address, grew directly out of this practice.
Estate and equestrian property. Homes where acreage, outbuildings, pasture and privacy carry the value — the current offerings at 90 Longhorn Ridge Road and 95 Longhorn Ridge Road, a 78-acre equestrian estate across three parcels, are representative of the work.
Vineyard-potential land. Parcels where planting is possible — and honest counsel about where it is not, in a county whose agricultural and hillside protections are the strictest in California.
The K2 connection
K2 Investment, Inc. was founded in 1994 by Siamak’s brother, Bobak Kalhor (Broker of Record, CA DRE #01198998), and has operated as a boutique brokerage ever since — Downtown Los Angeles commercial on one side, Napa Valley estate and land on the other, with the same principle on both: the person you call is the person who does the work. For Napa questions, that person is Siamak.
