C. R. Homes, based in Pahrump, has built approximately 60 custom homes since it was founded five years ago by the husband and wife team of Randy and Charlene Pasqualetto.  Its impressive growth rate can be partly attributed to location, since the population of Pahrump has doubled since 1995.  New residents, chiefly retirees from California, are drawn to the area by low land prices.  They can buy a 2,100-square-foot home on 1.25 acres in Pahrump for under $150,000, according to Charlene.  However, she stated, the real reason for C.R.'s success is referrals from satisfied customers.  "We have great subcontractors who help us build a reasonably-priced, quality product,"  she said.  "Clients are happy with their homes and recommend us to their friends."  Rapid growth has caused few problems for C.R. Homes, according to the Pasqualettos.  "Things can get hectic at times, but we're both very organized people.  We were also willing to put in extra hours if needed to get the job done."  said Charlene.  She also stressed the importance of self-discipline and fiscal responsibility.  "We had to remember that the construction industry is sporadic, and to plan for its 'boom-and-bust' cycles," she said.  The Pasqualettos foresee continued success, especially since many Las Vegas residents are looking to Pahrump as an alternative to an increasingly expensive and hectic life in the city.  "However,"  they said, "maintaining a growth rate over 1000 percent may be unrealistic.  It depends on what God wants.
