John Ronis holds California DRE 01846535 and handles both commercial and residential transactions through Coldwell Banker Realty from his Fuerte Drive office in La Mesa's Mt Helix area. His dual commercial-residential practice requires property and liability coverage coordination, a compliance step he manages with carriers such as Amanda Hammett - State Farm Insurance Agent for both owner-occupied and investment-property clients. Coverage spans La Mesa's 91941 ZIP from the Avocado Boulevard hillside corridor through the Grossmont Center retail zone and along Fletcher Parkway's mixed-use commercial frontage. Pre-sale roof assessments on aging commercial and residential inventory are routed through contractors such as Raindance Roof Company Inc to resolve inspection-flagged issues before buyer contingency periods begin. Highest-tier services include commercial lease-versus-buy analysis, triple-net lease negotiation with CAM reconciliation for retail tenants, and California Transfer Disclosure Statement compliance across San Diego County's overlapping municipal jurisdictions.
