Trying to decide between a townhome or a single-family house in Mountain View? You are not alone. The sticker price is only part of the story. The real difference shows up in monthly bills, long-term maintenance, and how the property fits your lifestyle. In this guide, you will see what truly drives total cost of ownership, how neighborhood location changes the math, and a simple framework to compare options side by side. Let’s dive in.
What drives true cost in Mountain View
Purchase price and financing
Townhomes often cost less than single-family homes because the land component is smaller. That gap can shrink in walkable areas near Castro Street, Caltrain, and major employers like Google or LinkedIn, where demand is strong. Financing can also differ. Some condo or townhome communities require project approval for certain loans, and some lenders may price those loans differently. Single-family purchases typically offer broader loan options with fewer eligibility hurdles.
Property taxes under Prop 13
California property taxes are based on your assessed value, typically near 1% plus parcel-specific assessments. Because single-family homes usually sell for more in absolute dollars, the annual tax bill is higher even though the rate is similar. Remodels, additions, and ADUs can trigger reassessment events that change future taxes.
HOA dues and special assessments
Most townhomes have HOAs. Dues help cover exterior maintenance, roofing, landscaping, common areas, and master insurance. Dues vary by age, amenities, and reserves. Older complexes near downtown can have aging infrastructure. Newer developments in places like North Whisman or Shoreline may have higher dues and healthier reserves. Special assessments can occur when reserves are not sufficient for big projects like roof replacement or seismic work.
Insurance realities
Townhome owners typically carry an HO-6 policy for interior coverage, while the HOA’s master policy covers the exterior and common areas. Single-family owners need full dwelling coverage (HO-3), which usually costs more. Earthquake coverage is optional and can be a significant add-on for both property types in the Bay Area.
Maintenance and replacements
With a single-family home, you are responsible for the whole structure, yard, fencing, and many capital items. A common rule of thumb is to budget about 1% of the home’s value per year for maintenance, adjusting for age and condition. Townhomes can reduce out-of-pocket maintenance because the HOA handles many exterior items, but those costs are embedded in dues and potential assessments.
Utilities and operating costs
Shared walls in townhomes can reduce heating and cooling demand, which helps monthly bills. Single-family homes often have higher water and landscaping costs due to private yards, along with exterior lighting and irrigation.
Parking, storage, and soft costs
Single-family homes usually offer a private garage and driveway with flexible guest parking. Townhomes may have assigned spaces and limited guest spots. If you value easy parking, tool storage, and workshop space, factor that into your decision along with the time you will spend on lawn care or coordinating HOA vendors.
Remodeling, ADUs, and flexibility
Single-family homes generally offer more freedom to remodel or add an ADU, subject to city rules. HOAs often set limits on exterior changes, and structural work can require approvals. While California made it easier to add ADUs, townhomes and condos still face HOA rules and shared-ownership constraints. If you plan to add living space or rental income, the single-family path is usually more straightforward.
Resale, liquidity, and appreciation
In high-demand areas with limited land, the larger land component in single-family properties can support stronger long-term appreciation. Townhomes near transit and major employers can perform well too, though they can be more sensitive to HOA health and shifts in buyer sentiment. Both property types share typical closing costs, while condo communities introduce occasional timeline risk if project-level issues arise.
Mountain View neighborhoods to compare
Downtown and Castro Street
Expect a higher concentration of condos and townhomes with strong demand for walkability and Caltrain access. Outdoor spaces are smaller, and parking can be tighter. Dues and special assessments vary by building age and reserves.
Cuesta Park, Waverly Park, and Old Mountain View
You will find many single-family homes on established lots with room to personalize and potential for additions. Maintenance, landscaping, and capital projects are larger responsibilities. Any major changes can affect tax assessments.
North Whisman and Shoreline West
These areas include newer developments with mixed property types and proximity to tech campuses and Shoreline Amphitheatre. Townhomes here may feature amenities and higher HOA dues, with stronger reserve positions.
Mountain View Hills and nearby pockets
Expect larger lots and single-family homes that come with increased landscape and exterior upkeep. Some parcels offer views. Budget for higher maintenance in line with property size and complexity.
East Whisman and Moffett Park area
A mix of townhomes and single-family homes with convenient access to corporate campuses. For buyers who prioritize commute time, this location can narrow the cost gap between property types.
Monthly comparison framework you can use
Build a simple apples-to-apples view before you shop. Start with the same down payment and rate for both options.
- Mortgage principal and interest
- Property tax estimate (assessed value multiplied by the local effective rate)
- HOA dues for townhomes
- Homeowners insurance (HO-3 for single-family vs HO-6 for townhome)
- Utilities (electric, gas, water, sewer, trash)
- Maintenance reserve (about 1% per year for single-family; townhome may be lower, with some costs built into HOA dues)
- Parking or permit costs if applicable
- Monthly reserve for potential HOA special assessments
Note on HOA dues: local townhome dues often fall into broad bands. Low can be around 200 to 400 dollars per month, mid can be around 400 to 800 dollars, and high can exceed 800 dollars depending on amenities and age. Confirm with actual HOA budgets and reserve studies.
The 5- and 10-year view
Monthly math tells part of the story. Long-term ownership includes bigger line items and exit costs.
- Add total monthly costs over 5 and 10 years.
- Include capital expenditures like roof, HVAC, exterior painting, landscaping, and driveway work. Single-family homes tend to have larger items.
- Subtract any potential rental income from an ADU if feasible.
- Account for transaction costs at sale.
- Model appreciation and equity outcomes under conservative assumptions. Single-family properties often benefit from land scarcity, while townhomes can appreciate strongly in sought-after locations near transit and employers.
When a townhome makes sense
- You value walkability to Castro Street or transit and want a shorter commute to major campuses.
- You prefer predictable exterior upkeep handled by an HOA and do not need a large private yard.
- You want a lower entry price than many single-family options and efficient interior space.
- You are comfortable reviewing HOA documents, reserves, and potential special assessment risk.
When a single-family home makes sense
- You want maximum control for remodeling, outdoor living, and potential ADU options.
- You prefer private parking, storage, and yard space.
- You are comfortable budgeting for full-structure maintenance and higher property tax in absolute dollars.
- You want a path that often supports stronger long-term appreciation due to the land component.
Questions to ask before you write an offer
For both property types
- What is the current assessed value and annual property tax bill?
- What capital improvements were completed, and when?
- What are the utility averages for the past 12 months?
Townhome and condo specifics
- Can you share the current HOA budget, reserve study, and recent meeting minutes?
- What does the master insurance policy cover, and what falls to the owner?
- Are there rental restrictions or pending litigation?
- Have there been special assessments in the past 5 years, or are any planned?
Single-family specifics
- Are there recorded easements, shared driveways, or CC&Rs that affect use?

Where to verify numbers
- Santa Clara County Assessor for parcel tax data and assessed value
- City of Mountain View Planning for ADU rules, zoning, and permits
- Lenders for loan options and condo project approvals
- Insurance brokers for HO-3, HO-6, and earthquake quotes
- Utility providers for rate schedules and usage estimates
- HOA documents for dues, reserves, and rules
Red flags that change total cost

- Structural issues or unclear maintenance responsibilities for shared elements
How nearby markets compare
Across the Bay Area, limited land tends to support single-family appreciation over long periods. In urban, transit-rich neighborhoods such as those found in Oakland and Berkeley, townhomes can perform well when demand for walkability is high, but they may be more sensitive to shifts in interest rates and project-level health. In Santa Clara and Mountain View, proximity to major employers can compress price gaps between townhomes and single-family homes, especially in areas that cut commute time.
