Key Cost Drivers in San Marcos
What pushes budgets higher for San Marcos residents? Housing costs are the biggest factor, with the median rent for a one-bedroom apartment exceeding $1,800 in 2025. Families seeking a single-family home can expect to pay upwards of $2,500 per month in mortgage payments alone.
Utilities also eat up a sizable chunk of income, especially for larger households. With summer temperatures regularly topping 85°F, air conditioning is a must for most—and it doesn’t come cheap. Budget $150 to $300 per month for electricity in the hot months.
Transportation costs are another pain point. While central San Marcos is relatively walkable, most residents rely on their cars to get around. Expect to spend $300 or more per month on gas, maintenance, and car payments. Bus and rail fares in San Marcos can help trim these costs if you live and work along major routes.
