Old Mission Realty is the public-facing brand for Steven Green's San Diego real estate practice, operating under Protege Properties from a Fourth Avenue storefront two blocks from Balboa Park in Hillcrest. Listing prep on 1920s bungalows frequently uncovers moisture intrusion behind plaster walls, which Precision Mold Testing documents before the seller's pre-listing disclosure hits MLS. The practice covers buyer and seller representation across the 92103 corridor, with listings pulled from the San Diego MLS rather than siloed IDX feeds. Homeowners insurance binders on older wood-frame Craftsmans — which wildfire and earthquake surcharges make tricky — get placed through Belltown Insurance Group Inc. during the 21-day contingency window. The most complicated files involve pre-1940 homes with galvanized plumbing, knob-and-tube wiring, and deferred foundation issues that all need lender-mandated repairs negotiated before funding.
