Housing is the biggest line item in most Silicon Valley budgets, and the Guptas are no exception. They’re looking for a 3-bedroom home with a bit of yard space for the kids. In Mountain View, the median price for a single-family home hovers around $2.1 million in 2025, while Sunnyvale comes in slightly lower at $1.9 million.

For a family like the Guptas, the lower home prices and rents in Sunnyvale could translate to significant savings over time. Young tech professionals, on the other hand, might prioritize Mountain View’s proximity to employers like Google, even if it means paying a premium on housing.

Utilities and Energy Expenses
Powering a home in Silicon Valley doesn’t come cheap, but Mountain View and Sunnyvale are relatively close in terms of utility costs. Residents in both cities can expect to pay around $250 per month for electricity, gas, water, and sewer for a typical 3-bedroom home.
Sunnyvale does have slightly lower electricity rates, thanks to the city’s municipal utility, Silicon Valley Power. Mountain View residents, meanwhile, are served by PG&E, which has somewhat higher rates but also offers more renewable energy options.
Families in larger or older homes may see higher utility bills, particularly for heating and cooling. Newer construction tends to be more energy-efficient, which can help keep costs in check.
🏆 Winner: Sunnyvale, but it’s close. The city’s municipal utility gives it a slight advantage.
Comparing Grocery and Food Costs
Feeding a family in Silicon Valley can add up quickly, as the Guptas are well aware. They’re budgeting around $1,200 per month for groceries and dining out. Prices for staples like milk, bread, and eggs are fairly consistent between Mountain View and Sunnyvale, with both cities hovering about 20% above the national average.
Where the cities differ is in the cost of dining out. Mountain View’s restaurant scene is a bit pricier, with an average meal for two running $80-$100 at a mid-range eatery. In Sunnyvale, a comparable meal might cost $70-$90.
Of course, savvy shoppers can find deals in both cities by comparing prices at different stores and farmers markets. Buying in bulk at stores like Costco can also help families like the Guptas stretch their grocery budget.
🏆 Winner: Sunnyvale, thanks to its slightly lower restaurant prices. But smart shopping can level the playing field.
Taxes and Fees in Mountain View vs. Sunnyvale

It’s also worth noting that some neighborhoods in both cities have additional assessments or HOA fees. These can vary widely, but tend to be more common in newer developments.
🏆 Winner: Sunnyvale. The lower UUT gives it a slight edge, but taxes are generally high in both cities.
