About Landmark Appraisal Company

Landmark Appraisal Company, a family owned, local Washington business for the past 35 years has been appraising residential homes, farms, vacant land, commercial property, including retail and industrial, multi-family buildings and estates.


We cover a 10-county area including, Franklin, Warren, Gasconade, Crawford, Montgomery, St. Charles, and parts of, St. Louis, Maries, Phelps and Jefferson.  


Our knowledge of the local area with its rolling hills, river properties, new and old subdivisions and growing commercial areas is extensive. Some of our clients include local banks, Bank of Washington, Peoples Bank, First Bank, Peoples Savings Bank, Heritage Community Bank and Citizens Bank.  We also do work for numerous mortgage companies, relocation specialists and lawyers including estate work. We have also done some MODOT work with the widening of Highway 100 from Washington to Interstate Highway 44 and the 185 extension in Sullivan, where many changes are anticipated in the near future.  

Property appraisals include:

  • Single Family Residential (existing and new construction)
  • Multi-family Residential
  • Condominiums
  • Vacant Land
  • Farms
  • Commercial / Industrial

Our Process

Our continued updating of technology has enabled us to send residential, commercial and land appraisals to our clients electronically or if you prefer, a hard copy. We do appraisals for local banks, lawyers, credit unions, and personals.  Our fees are competitive and our turn-around times reasonable.  


Our turnaround time varies and depends on our workload, however, we will do our best to accommodate your schedule.  We feel we do a “good” appraisal, not a fast, generic report. We do research through county records, obtain plats, specs and plans, deeds and call realtors or surveyors for other information if required.  


Call our office and talk to one of our appraisers and ask questions and we will do our best to give you the kind of appraisal YOU want.
