Zero Point Loans is a San Diego mortgage brokerage at 4440 Twain Ave, Suite 101, in Grantville within the 92120 ZIP, founded by Michael Spirtos under corporate NMLS #1840597 and personal NMLS #691241. The firm originates FHA, VA, conventional, jumbo, USDA, down-payment-assistance, and construction loans through a broker model that shops multiple wholesale lenders to target the lowest available rate-and-fee combination for each borrower profile. Grantville property transactions involve pre-purchase inspections, title searches, and the exterior-maintenance clearances that escrow officers require before releasing funds, and corridor vendors such as All County Power Wash & Steam Cleaning, Inc. handle the surface preparation that seller concessions and lender-required repairs sometimes mandate before closing. Twain Avenue intersects Mission Gorge Road a block south of Mission San Diego de Alcala, placing the office at the geographic center of Grantville's commercial corridor where auto dealerships, breweries, and service businesses generate the employment base whose W-2 income drives mortgage qualification volumes. The digital mortgage platform streamlines document collection, e-signature execution, and automated underwriting submissions, compressing the span from application to conditional approval. The firm's product menu includes HECM reverse mortgages for homeowners sixty-two and older, a program segment that serves the 92120 ZIP's aging-in-place population concentrated between Allied Gardens and Del Cerro. SDSU student-housing investment purchases along the Mission Gorge and College Avenue corridors represent a secondary borrower segment, where rental-income projections factor into debt-to-income ratios on investor-grade conventional loans, and community-housing organizations such as Wesley House Student Residence Inc anchor the institutional rental stock that sets comparable-rent baselines for those appraisals. Construction-loan origination pairs the firm with Grantville-area general contractors pulling permits for additions, ADU builds, and full remodels — projects that require draw-schedule coordination between the lender, the borrower, and the building department.
