The Costs Rialto Homebuyers Forget to Budget For

by Amanda Zito

What costs do Rialto homebuyers sometimes forget to budget for?

Most buyers plan for the down payment, closing costs, and monthly mortgage payment.

But owning the home can come with a few other expenses that are easy to miss.

Things like supplemental property taxes, Mello-Roos or other special assessments, homeowners insurance, solar payments, HOA fees, utilities, and future repairs can all affect what a home really costs each month.

None of these costs are necessarily hidden. They are just easy to overlook when you're focused on finding a home, getting your offer accepted, and making it through escrow.

Here are some of the costs I tell Rialto buyers to look at before writing an offer.

Your Mortgage Payment Isn't the Whole Picture

Your lender will usually give you an estimated monthly payment that includes:

Principal and interest
Estimated property taxes
Estimated homeowners insurance
Mortgage insurance, if required

That's a good starting point.

But there may be other costs that aren't fully reflected in that first estimate, including:

Supplemental property taxes
Mello-Roos or other special assessments
Higher insurance costs
Solar lease or PPA payments
HOA dues or special assessments
Utilities
Maintenance and repairs

The goal isn't to scare you away from buying.

It's to make sure you know what you're walking into before you own the home.

Don't Forget the Supplemental Property Tax Bill

This is one of the biggest surprises I see with California homebuyers.

When you buy a home, the county reassesses the property based on your purchase price.

If the seller bought the home years ago, their assessed value may be much lower than what you paid.

The county can then send you a separate supplemental property tax bill for the difference.

For example, let's say the seller's assessed value was $250,000 and you buy the home for $550,000.

That's a $300,000 increase in assessed value.

At California's 1% base property tax rate, that difference alone could represent roughly $3,000 per year before additional local taxes and assessments are included.

Your actual supplemental bill will depend on when you close and the property's tax situation.

Why buyers get caught off guard

The bill may arrive several months after closing.

And it is usually mailed directly to you rather than automatically paid through your mortgage lender.

That means you could already be settled into the home when a separate tax bill suddenly arrives.

Your escrow or impound account can also be adjusted later if the lender originally estimated your property taxes using the seller's lower tax amount.

That could mean a higher monthly mortgage payment after your lender completes its escrow review.

What to do before you buy

Look at the property's current tax bill and estimate the taxes based on your expected purchase price.

San Bernardino County also offers tools for new homeowners to help estimate property taxes.

I would rather have a buyer plan for that expense before closing than be surprised by it later.

Check for Mello-Roos and Other Special Taxes

Property taxes aren't always just the basic 1%.

Some properties also have special taxes or assessments.

One you may hear about is Mello-Roos, also called a Community Facilities District or CFD.

These taxes are often used to help pay for infrastructure in newer communities, including things like:

Roads
Parks
Water and sewer systems
Other public improvements

The amount can vary from one neighborhood to another.

You may also see other charges on the property tax bill, such as landscape or lighting assessments.

How to check

Ask for the seller's current property tax bill and look at the entire bill — not just the total amount.

You can also look up the property with the county using the parcel number.

This is especially important because two homes with similar prices can have very different annual property tax bills.

Homeowners Insurance Can Change the Numbers

Homeowners insurance has become a much bigger part of the conversation for California buyers.

The cost can vary quite a bit depending on the exact property.

Two homes only a few miles apart may receive very different insurance quotes.

Things like the property's location, age, condition, roof, claims history, and fire-risk area can all matter.

Some homes may also need coverage through the California FAIR Plan.

But the FAIR Plan generally isn't the same as a traditional homeowners policy.

You may need an additional Difference in Conditions policy for coverage such as liability, theft, or certain types of water damage.

That can mean paying more than one insurance premium.

Earthquake coverage is also separate from a standard homeowners policy.

What I recommend

Get an actual insurance quote for the property while you're still in your inspection and contingency period.

Don't rely only on a general estimate.

You want to know what that specific home will cost to insure before you fully commit.

Utilities Can Vary Around Rialto

Your monthly utilities can also depend on where the home is located.

Not every property in and around Rialto has the same water provider, and different providers can have different rates.

Then there is electricity.

If you've lived in the Inland Empire, you already know how hard an air conditioner can work during the summer.

An older home with:

Older windows
Limited insulation
Older HVAC equipment
Leaky ductwork

may cost more to cool than a newer or more energy-efficient home.

A simple thing to ask for

Ask the seller if they can provide approximately 12 months of utility bills.

One or two months won't tell you much.

A full year gives you a better look at what the home costs during the hottest part of the summer too.

Solar: Owned, Leased, or Financed?

I see this one confuse buyers all the time.

A listing may simply say:

"Home has solar."

But that doesn't tell you enough.

You need to know how the solar is owned.

Owned solar

If the solar panels are owned outright and included with the home, there may be no separate monthly solar payment.

Leased solar or PPA

If the solar is leased or under a power purchase agreement, there may be a monthly payment that transfers to the buyer.

You may also need to qualify with the solar company.

Some agreements last many years and may include increases in the payment over time.

Financed solar

The seller may still have a solar loan attached to the system.

There could also be a PACE assessment tied to the property tax bill.

These issues usually need to be addressed during the transaction.

What to ask for

Don't stop at the seller's disclosure.

Ask for the actual solar agreement.

Look for:

Current monthly payment
Years remaining
Possible annual increases
Transfer requirements
Payoff information

You want to understand the agreement before removing your contingencies.

HOA Dues Aren't Always the Only HOA Cost

Some Rialto condos, townhomes, and communities have homeowners associations.

The regular monthly HOA dues are usually easy to find.

But you should also pay attention to the financial health of the HOA.

If the association doesn't have enough money in reserves, large repairs may lead to a special assessment.

That could mean an additional payment on top of your normal HOA dues.

During your review period, look at documents such as:

HOA budget
Reserve study
Recent meeting minutes
Pending or planned special assessments

The monthly HOA fee is only one part of the picture.

Older Homes Need a Maintenance Budget

Rialto has many homes that were built decades ago.

That isn't necessarily a negative.

Older homes can have great layouts, larger lots, mature neighborhoods, and plenty of character.

But older homes also tend to have older systems.

Before you buy, pay attention to the age and condition of things like:

Roof
HVAC system
Water heater
Plumbing
Sewer line
Pool equipment
Fencing and block walls

Some homeowners use around 1% of the home's value per year as a rough starting point for maintenance.

I wouldn't treat that as a hard rule.

A five-year-old home and a fifty-year-old home can have completely different maintenance needs.

Instead, use your home inspection to start building a realistic picture of what may need to be repaired or replaced over the next few years.

For older homes, a sewer camera inspection may also be worth considering.

How to Figure Out the Real Monthly Cost Before You Offer

Before writing an offer on a Rialto home, I like buyers to look beyond the mortgage payment.

Try to estimate:

Principal and interest
Property taxes based on your expected purchase price
Mello-Roos or other special assessments
Homeowners insurance for the actual property
HOA dues, if any
Solar payments, if any
Average utilities
A realistic maintenance budget

And don't forget to set aside money for the supplemental property tax bill.

Once you put everything together, you get a much better idea of what the home will actually cost to own.

And that's the number that matters.

If it still fits comfortably within your budget, great.

If it doesn't, it's much better to find that out before you buy than six months after you move in.

Frequently Asked Questions

When will I receive a supplemental property tax bill after buying in San Bernardino County?

It can take several months after closing.

The bill is generally mailed directly to the property owner, so don't assume your mortgage company will automatically take care of it.

When it arrives, contact your loan servicer if you're unsure how it should be handled.

Is Mello-Roos included in my mortgage payment?

It may be included if you have an impound account and your lender is collecting for the property's taxes.

But the important question is whether your lender's original estimate included the correct amount.

Review the property's current tax bill so you know what special taxes or assessments are attached to the home.

Do I have to take over the seller's solar lease?

Not necessarily.

Depending on the contract and negotiations, the buyer may assume the solar agreement or the seller may need to pay it off.

This is why reviewing the solar contract early in escrow is so important.

Know What the Home Really Costs Before You Buy

The purchase price is only the starting point.

A home may look affordable based on the mortgage payment alone, but taxes, insurance, solar, utilities, HOA fees, and maintenance can change the monthly picture.

Before you write an offer, take a little extra time to look at the whole cost of owning the home.

It can save you from some very expensive surprises later.
