DT America Realty & Mtg Inc operates a combined San Diego real estate brokerage and mortgage origination office in College Area at 5227 El Cajon Blvd in the 92115 ZIP. The firm, also known as TranAmerica Realty & Mortgage, holds DRE# 01896136 under broker Denny Tran, who specializes in single-family residence and income-property transactions. Property-tax planning for investment-property buyers and 1031-exchange sellers coordinates with local preparers including Pelayo Tax Service on El Cajon Blvd for annual Schedule E filings and depreciation-schedule setup. El Cajon Boulevard's commercial corridor runs east-west through College Area with direct access to SDSU's campus, and the office sits in the stretch of the boulevard that serves a mix of residential clients, international dining, and student-adjacent services. The mortgage division originates conventional, FHA, and VA loans in-house, allowing buyers to pair property search and financing through a single point of contact—an efficiency that compresses the pre-approval-to-close timeline on purchase transactions. Tran's brokerage handles listing preparation, MLS syndication, buyer showings, offer negotiation, and escrow management for properties in College Area, Allied Gardens, Grantville, and the broader 92120 market. Income-property analysis covers gross rent multiplier, cap-rate benchmarking, and cash-on-cash return modeling for two-to-four-unit residential investment acquisitions that qualify for conventional financing. Rekeying and lockbox management on closed transactions and new rental turnovers routes through Lock Techs for master-key system installation and smart-lock upgrades on multi-unit properties. The dual brokerage-and-lending structure carries separate DRE oversight for real estate sales and mortgage origination, with loan disclosures, good-faith estimates, and closing documents processed under California's Real Property Loan Law.
