Does This House Have Mello-Roos?

Why check before the offer, not after

A lender counts Mello-Roos as part of your monthly housing cost, along with the mortgage payment. It comes out of the same budget, so it changes the price you can afford. At a $150,000 household income, each $100 a month of special tax lowers the price you qualify for by roughly $15,000 on a conventional loan. The affordability guide for $150,000 shows the full calculation. Knowing the figure first lets you price your offer around it.

1. Run the address through a free report

The fastest check: enter the address into sounding. It reads the county's special-assessments data for that parcel and puts any Mello-Roos into the monthly cost, next to the property tax, insurance and loan payment for each loan program.

2. Look the parcel up on the county portal

San Diego County publishes a Special Assessments portal that lists the special taxes and assessments on a parcel. You search by Assessor's Parcel Number (APN), which appears on the seller's tax bill and in most listing details. The Assessor's Mello-Roos page walks through the lookup step by step. The county also keeps a list of its active Community Facilities Districts, useful for seeing which agencies levy them and who administers each.

3. Read the seller's current tax bill

Ask the listing agent for the seller's most recent property tax bill. Mello-Roos charges appear as their own lines, separate from the base property tax, with the district's name and contact information, according to the City of San Diego's CFD FAQ. The bill shows what the seller paid this year. It does not show how the tax changes over time, which is the next step.

4. Check the disclosures once you are in escrow

Forming a CFD records a Notice of Special Tax Lien against every parcel in it, so the preliminary title report flags it. Separately, California Civil Code § 1102.6b requires the seller to make a good-faith effort to give you a notice of the special tax. Read both closely: they usually arrive after your offer is accepted, so treat them as confirmation of what steps 1 to 3 already told you.

Questions to ask once you find one

• How much, and how fast does it grow? Each district sets a formula, its Rate and Method of Apportionment, with a defined maximum tax and annual increase.
• When do the bonds pay off? A district a few years from payoff is a very different cost from one that issued bonds recently.
• Does anything continue after payoff? Some districts keep a smaller levy for maintenance or services after the bonds are retired.

The district named on the tax bill can answer all three. For background on how these districts work, see what Mello-Roos is and Mello-Roos by community.
