Think the mortgage payment is the whole story? In Dublin, your true monthly cost also includes property taxes, potential Mello Roos special taxes, utilities, HOA dues, insurance, and a maintenance reserve. If you are budgeting for the East Bay, you want a clear, no‑surprise number. This guide walks you step by step through a Dublin‑specific worksheet, explains what to check on each property, and gives you a sample calculation. Let’s dive in.
What your all‑in monthly cost includes
Mortgage principal and interest (P&I)
Your base payment depends on your loan amount, interest rate, and term. Use your lender’s Loan Estimate or a trusted calculator to compute it. You can test numbers with the Fannie Mae mortgage calculator for a quick check of monthly P&I.
- Helpful tool: Try the Fannie Mae mortgage calculator to model P&I and amortization.
Property taxes in Dublin
California property tax starts with a 1 percent base on assessed value, plus voter‑approved rates and parcel charges. After a purchase, the assessed value usually resets close to your price, then can grow up to 2 percent per year. For planning, Dublin buyers often use a conservative 1.1 percent to 1.4 percent of purchase price until they confirm the parcel’s exact bill. See the Alameda County Assessor’s guidance on estimating taxes.

Expect a separate supplemental tax bill after closing if the new assessed value is higher than the seller’s. It prorates the difference for the rest of the fiscal year. The Assessor explains how this works and when it arrives.

Special taxes: Mello Roos and CFDs
Several Dublin neighborhoods sit inside Community Facilities Districts that levy an annual special tax. This can be hundreds or thousands per year and is parcel‑specific. Always check the current tax bill and the city’s CFD maps before you finalize your budget.
- Where to check: City of Dublin Community Facilities Districts
Homeowners insurance
Premiums vary by coverage level, age of home, and location. A common Bay Area planning range is about 1,000 to 1,500 dollars per year for a typical single‑family home, but quotes vary. Get two or three local quotes before you finalize your monthly number.

Mortgage insurance (if down payment is under 20 percent)
Conventional loans may require PMI, which often runs roughly 0.5 to 1.5 percent of the loan amount per year and is usually paid monthly. FHA loans charge an upfront and an annual mortgage insurance premium. Your lender will give you exact figures for your program.
- Overview: PMI ranges and factors
HOA dues
If the home is in an HOA, add the monthly dues. Condos and townhomes often have higher dues that cover amenities and exterior maintenance. Always request the HOA resale packet to confirm dues, reserves, and any pending special assessments.
Utilities and city services
Water and sewer service in Dublin is provided by DSRSD, which bills bimonthly. Convert those numbers to a monthly estimate for your budget. Solid waste service is provided by Amador Valley Industries through the City of Dublin. Electric and gas are through PG&E, and usage varies by household.
- DSRSD rates and calculators: Water and wastewater rates
- Trash and recycling: City of Dublin solid waste services
Maintenance and reserves
Plan a monthly set‑aside for upkeep and future repairs. A common starting point is 1 percent of purchase price per year, divided by 12. Newer homes may need less, older homes may need more. Fannie Mae offers tips on building a maintenance budget.

One‑time costs that affect affordability
Closing costs in California often average near 1 percent of the purchase price, though totals vary by loan and fees. You may also see county and city transfer taxes in Dublin. While these are not monthly, they impact your cash at closing and your overall plan.

Your Dublin all‑in worksheet
Gather these inputs
- Purchase price, down payment percent, and loan amount from your lender.
- Interest rate and term from your Loan Estimate.
- Property tax estimate or the exact parcel levies using the Alameda County Assessor’s tools.
- CFD/Mello Roos special tax amount from the current tax bill or the city’s CFD pages.
- Homeowners insurance annual premium from two or three quotes.
- HOA dues from the HOA resale packet, if applicable.
- Utilities: DSRSD water and sewer, trash service through the city’s provider, and your estimated PG&E usage.
- Monthly maintenance reserve, such as 1 percent of price per year divided by 12.
Calculate step by step
- Step A: Monthly P&I from the loan amount, rate, and term. Use your Loan Estimate or a trusted calculator like the Fannie Mae mortgage calculator.
- Step B: Monthly property tax. If you do not have the exact assessed value yet, plan on 1.1 to 1.4 percent of purchase price per year, then divide by 12. See the Assessor’s estimating guide.
- Step C: Monthly homeowners insurance. Take your quoted annual premium and divide by 12.
- Step D: Mortgage insurance, if required. Use your lender’s figure. If you need a placeholder, try 0.75 percent of the loan amount per year, divided by 12, then confirm with your lender. See PMI factors for context.
- Step E: HOA dues, if any.
- Step F: Utilities. Convert any bimonthly DSRSD bills to a monthly number. Add trash and your PG&E estimate. Use DSRSD rates and the City’s solid waste page as references.
- Step G: Maintenance reserve. Use your chosen annual percent divided by 12. For example, 1 percent per year.
- Step H: Add any other recurring items like landscape service or security.
- Step I: Sum Steps A through H to get your estimated all‑in monthly cost.
Example: plug in sample numbers
This example shows how the math stacks up. Replace every number with your lender quotes and the parcel’s actual bills.
- Purchase price: 1,200,000 dollars. Down payment: 20 percent. Loan: 960,000 dollars. 30‑year fixed at 6.5 percent gives P&I about 6,060 dollars per month.
- Property tax at 1.25 percent: about 15,000 dollars per year, or 1,250 dollars per month.
- Homeowners insurance: 1,200 dollars per year, or 100 dollars per month.
- HOA dues: 400 dollars per month.
- Utilities and trash: 300 dollars per month.
- Maintenance reserve at 1 percent: 12,000 dollars per year, or 1,000 dollars per month.
Estimated all‑in monthly cost: about 9,110 dollars per month.
Sensitivity check: If you use 1.1 percent for property tax instead of 1.25 percent, tax drops to about 1,100 dollars per month. At 1.4 percent, it rises to about 1,400 dollars per month. Plan a buffer for the first year’s supplemental assessment, and always verify any CFD special tax on the parcel.
