Ever see “Mello-Roos” on a San Diego listing and wonder what it really means for your payment? You are not alone. Special taxes can be confusing when you are focused on neighborhoods, views, and floor plans. This guide breaks down what Mello-Roos is, how to spot it, what it might cost, and how it affects your mortgage so you can compare homes with confidence. Let’s dive in.
Mello-Roos basics in San Diego
Mello-Roos is a special tax created by a Community Facilities District, often called a CFD. Local agencies use CFDs to finance public infrastructure and sometimes services, such as roads, parks, schools, storm drains, and utilities. The district may issue bonds, and the parcels inside the CFD repay those bonds through a special tax.
This tax is separate from your regular property tax under Proposition 13. It sits on top of your ad valorem taxes and, in many cases, runs for a set period or until bonds are repaid. Some districts include built-in annual increases that follow a fixed percentage or a CPI-style adjustment, so the amount can escalate over time.
Across San Diego County, many newer master-planned communities formed CFDs to fund the amenities you see today. If you are comparing recently built neighborhoods, you are more likely to encounter Mello-Roos than in older, established coastal enclaves. Each district is unique, so avoid assumptions and verify for the specific property.
How to spot it on a property
Listing clues to watch
Look for terms like “Mello-Roos,” “CFD,” “special tax,” “community facilities district,” or “buyer to assume special tax.” Some listings will display an annual amount. Others say “see tax bill,” and some do not mention it at all. The absence of a note does not guarantee there is no CFD. Always double-check.
Records to confirm
- Current and prior year county property tax bills. These often show a separate line for a CFD or special tax if it is collected with the county bill.
- Preliminary title report or tax certificate. These typically disclose special taxes or assessments tied to the parcel.
- CFD formation documents and the Rate and Method of Apportionment, or RMA. The RMA explains how the tax is calculated, how it may increase, and whether there is a sunset.
- Bond or official CFD notices and any recorded Notices of Special Tax.
- HOA documents and CC&Rs, if applicable, to see whether there are related assessments.
Where to look locally
You can use the San Diego County Treasurer-Tax Collector’s property tax lookup to see bill line items if the special tax is collected on the county roll. Some jurisdictions bill separately, so you may also need to contact the city or the district’s administrator. Your title company and escrow officer can pull the tax certificate and help confirm whether a CFD applies.
What it may cost you
There is wide variation in San Diego. The size of the district, the amount of infrastructure financed, the number of parcels sharing costs, and the RMA’s methodology all affect the annual amount. Some districts levy a flat figure. Others use a formula more like a property-value or unit-size approach.
In practice, annual Mello-Roos charges commonly range from a few hundred dollars to several thousand dollars per year across the county. High-amenity or coastal-proximate master-planned areas can be toward the higher end depending on the district. Many RMAs include built-in annual increases, so it is important to confirm both today’s amount and the escalation schedule.
To compare homes, convert the annual figure to a monthly number by dividing by 12. For example, a $2,400 annual special tax adds $200 per month to your housing costs. A $1,800 annual amount adds $150 per month. Use that monthly figure side by side with HOA dues and other costs to make an apples-to-apples comparison.
It is also wise to ask about the lifecycle. Some districts have sunset dates or step-down schedules. Others continue until bonds are paid, and refundings or prepayments can change the path over time. The RMA and recent bond documents will show what to expect.
Impact on loans and payment
How lenders count it
Most loan programs treat Mello-Roos as a recurring housing expense that must be included in your qualifying payment. Lenders will take the documented annual amount and divide by 12 to add it to your monthly PITI. If the amount can vary, an underwriter may ask for the RMA or use the higher of the current levy or the next projected figure.
DTI and program eligibility
Because the special tax increases your monthly payment, it can reduce your maximum loan amount at a given debt-to-income ratio. This is true across conventional, FHA, and VA programs, though each has its own guidelines and some lenders apply additional documentation requirements. Your pre-approval should explicitly include any known Mello-Roos so you are shopping with accurate numbers.
Escrow and billing
Many special taxes appear directly on the county property tax bill. If yours does, your lender will usually escrow it with your monthly mortgage payment. Some districts bill separately through an agency, in which case you may pay it directly. Confirm with your lender and servicer how your CFD will be collected so there are no surprises.
Smart buyer checklist
Documents to collect
- Current county property tax bill and, if possible, last year’s bill
- Preliminary title report or tax certificate
- CFD formation documents and the RMA
- Bond documents or official notices about the district
- Any recorded Notices of Special Tax
- HOA documents and CC&Rs, if applicable

Questions for the listing side
- Is the property inside a CFD or subject to Mello-Roos? If yes, what is the current annual amount for this parcel?
- Is the tax on the county bill or billed separately? When is it due and how is it collected?
- Is there a fixed term or sunset date? Are there bonds outstanding that affect the timeline?
- What is the schedule for increases, such as CPI or fixed steps? Are prior years’ amounts available?
- Are any prepayments, redemptions, or refundings planned that could change the levy?
Questions for your lender
- How will this special tax be included in my qualifying payment and DTI?
- Will you escrow it with my mortgage payment, or will I pay it separately?
- What documentation do you need, such as the RMA or county bill?
- Will this change the maximum I can borrow, and by roughly how much based on the current amount?
- Do you require reserves or have any overlays if the tax is significant or variable?
Questions for title and escrow
- Does the preliminary title report show recorded CFD liens or special tax notices?
- If the tax is on the county bill, will escrow set up impounds correctly at closing?
Other practical questions
- Is the special tax deductible on my federal or state return? Tax treatment can be complex. Consult a tax professional for advice specific to your situation.
- How does Mello-Roos affect resale in this neighborhood? Ask your agent for comparable sales with similar special taxes to see the local market impact.
Common myths and clarifications
- Mello-Roos vs HOA fees. Mello-Roos is a government special tax tied to a parcel to repay public financing or fund services. HOA dues are private assessments for association amenities and maintenance. A property can have both.
- Proposition 13 and your base tax. Mello-Roos does not change your assessed value under Prop 13. It is an additional special tax layered on top of your ad valorem taxes.
- Prepayment and cancellation. Some districts allow full or partial prepayment to redeem bonds early, but not all do. The bond documents and RMA control the rules.
- Assumption on sale. The special tax stays with the property. When you buy, you will pay the levy going forward. It does not work like assuming a seller’s loan.
Buying workflow for coastal neighborhoods
- Before touring. Ask your agent to flag listings that note Mello-Roos or CFDs. For any serious contender, review the current tax bill early.
- Pre-approval. Get pre-approved with the specific special tax included in your payment. This keeps your search aligned with what you can comfortably qualify for.
- Offer stage. Include contingencies to verify the tax amount, escalation schedule, and collection method. Request the last two to three years of tax bills when available.
- Prior to closing. Confirm whether the tax will be escrowed, verify any upcoming increases, and ensure your lender has all required documents so your loan funds on time.
Bottom line for San Diego buyers
Mello-Roos is common in many newer San Diego communities and can be a fair trade-off for modern infrastructure and amenities. The key is clarity. Identify whether a CFD applies, confirm the exact amount and escalation, translate it to a monthly cost, and bake it into your loan strategy. With the right information, you can compare two great homes on equal footing and move forward with confidence.
