San Diego’s rent-versus-own math favors patience: with 20% down, buyers need 23.3 yr to financially outperform renting under modeled conditions in the market.
The takeaway is planning horizon: shorter stays may not recoup closing costs, while longer ownership gives buyers more time to build equity.
Down payment strategy matters too: 20% down can help long-term finances, but it is not always the quickest breakeven path for buyers.
Smaller down payments preserve cash flexibility, but they can mean bigger mortgages, more interest, and mortgage insurance that adds buyer costs locally.
For San Diego renters seeking a financial edge, the model assumes unused down payment and closing-cost money gets invested, not simply spent.
