Home Buying
When you're buying a home in Fresno, the purchase price and mortgage payment are only part of the financial picture. Property taxes are another ongoing cost that should be included when planning your monthly housing budget.
California property taxes can be a little different from what buyers may expect, especially because of Proposition 13 and the way properties are reassessed after a purchase. Understanding how Fresno County property taxes work before you buy can help you avoid surprises later.
A common misconception is that property taxes are simply based on what a home is currently worth on the market.
In California, Proposition 13 generally establishes a property's base year value when it changes ownership. Fresno County explains that the purchase price is generally presumed to represent the property's fair market value at the time of purchase, although certain circumstances can affect the assessment.
That new assessed value becomes an important starting point for your future property taxes.
California's general property tax levy is limited to 1% of assessed value. However, your actual Fresno County property tax bill can be higher because additional voter approved bonds, special assessments, and other local charges may apply.
That's why buyers should avoid estimating their future tax bill by simply multiplying the purchase price by exactly 1%.
The actual amount can vary from property to property.
One of the most important things for Fresno homebuyers to understand is Proposition 13.
After the property's base year value is established, the assessed value generally cannot increase by more than 2% per year, although there are exceptions. If the property changes ownership or certain new construction is completed, reassessment can occur.
This means your future assessed value isn't necessarily going to rise at the same rate as the home's market value.
This is particularly important when purchasing a Fresno or Clovis home.
When a property changes ownership, the Fresno County Assessor generally reassesses it to determine its new fair market value. In most residential purchases, the entire property is subject to reassessment unless an exclusion applies.
This is why looking at the seller's current property tax bill doesn't necessarily tell you exactly what your taxes will be after closing.
The seller may have owned the property for many years and have a much lower assessed value than the value established by your purchase.
Another potential surprise for first time buyers is the supplemental property tax bill.
After a purchase, Fresno County may issue a supplemental assessment based on the difference between the property's previous assessed value and its newly established value. The supplemental taxes are prorated for the portion of the fiscal year remaining after the ownership change.
Importantly, a supplemental tax bill is in addition to your regular annual property tax bill.
If you have an impound or escrow account with your lender, don't automatically assume the lender will pay a supplemental bill. Fresno County specifically advises homeowners to contact their lender to determine who is responsible.
If the home will be your principal residence, you may qualify for California's Homeowners' Exemption.
The exemption can reduce the assessed value by $7,000. It isn't simply an automatic reduction for every property owner, so eligible homeowners should make sure they complete the appropriate application.
For supplemental assessments, Fresno County notes that eligible homeowners may also qualify, but specific filing deadlines apply.
When evaluating a Fresno home, don't rely solely on an online estimate.
Ask to review the property's current tax information and look at the different components of the bill. Fresno County notes that property tax bills can include the general countywide tax, bonds, special assessments, and other charges.
This is particularly important when comparing homes in different neighborhoods or developments because additional assessments can vary.
Property taxes aren't only affected by buying a home.
Certain new construction and substantial improvements can result in reassessment. Fresno County specifically identifies additions such as rooms, pools, and garages as examples that may require reappraisal, depending on the circumstances.
So if you're buying a home and planning a major renovation, addition, or other improvement, it's worth understanding how that work could affect the property's assessed value.
When determining what you can comfortably afford, look beyond the mortgage principal and interest.
Your overall housing budget may include:
• Mortgage principal and interest
• Property taxes
• Homeowners insurance
• HOA dues, if applicable
• Utilities
• Maintenance and repairs
• Special assessments
Adding these expenses together gives you a much clearer picture of the actual cost of owning a Fresno home.
Two homes that look similar and sell for similar prices can still have different tax situations because of differences in assessed value, special assessments, bonds, exemptions, or other charges.
That's another reason buyers should review the specific property rather than relying on a general Fresno property tax estimate.
Before purchasing a home, consider asking:
What is the current assessed value?
What are the property's current annual taxes?
Are there special assessments or additional charges?
Could a supplemental tax bill be issued after closing?
Will I qualify for the Homeowners' Exemption?
Will planned improvements potentially affect the assessed value?
Understanding these details before you buy can make your financial planning much more predictable.
Property taxes are an important part of the true cost of homeownership in Fresno. Proposition 13 provides a framework for how California properties are assessed and limits many annual increases, but a purchase can trigger reassessment and potentially result in supplemental taxes.
At Sawatsky Real Estate Associates - Cygnus Estates, we encourage buyers to look at the complete financial picture when evaluating a home.
