If you opened your Tempe tax notice or your mortgage statement and saw a surprise, you are not alone. Property values and tax bills can shift, and that change often flows straight into your escrow. You want to know what drives the numbers and what you can do about them. In this guide, you’ll learn how Arizona’s LPV and FCV work, how property class affects taxes, and why your mortgage escrow changes from year to year. Let’s dive in.
Full Cash Value, or FCV, is the assessor’s estimate of market value. Think of it as what a property would likely sell for in the open market. FCV can change more noticeably from year to year as sales, renovations, or new construction shift the local market.
Limited Property Value, or LPV, is an assessed value that uses state rules to limit how fast the taxable value grows. LPV is often the value local taxing districts use when calculating many parts of the property tax bill. LPV usually moves more slowly than FCV.
Arizona separates the market value from the taxable value to reduce sudden jumps in tax bills when prices spike. You might see FCV rise quickly in a hot market while LPV increases at a controlled pace. Since many levies use LPV, your taxes and escrow often track that limited value rather than the full market number.
Look at your annual Maricopa County assessor notice for both FCV and LPV, along with the property class code. Note year‑over‑year percentage changes. Any large change in these figures, or a class change, can affect your tax bill and your escrow.
Your property’s class reflects its use, such as primary residence, residential rental, commercial, or vacant land. Class matters because different rules and tax allocations can apply to different categories. Maricopa County publishes class codes on each parcel record.
An owner‑occupied home can be treated differently than a rental for certain valuations or exemptions, depending on local rules. A home that is converted from primary residence to rental, or the other way around, can be reclassified. Reclassification can change the taxable base, which can increase or decrease your property tax bill and, in turn, your escrow payment.
Class can change when the use changes or when the county updates records. Triggers include a change in mailing address, permits for remodeling, use information reported by the owner, or an inspection by the assessor. Class changes appear on the assessor’s annual notice and typically apply in the next tax cycle.
Most lenders include an escrow line in your monthly payment to cover property taxes and homeowner’s insurance. Each year your lender runs an escrow analysis to compare expected taxes and insurance for the coming year to your current escrow balance. If expected costs rise, your monthly escrow usually goes up. If costs fall, your payment can go down or you might receive a refund.
Federal rules require an annual analysis and allow lenders to hold a cushion, often up to two months of expected disbursements. This cushion helps cover timing differences when bills come due and can make the monthly escrow a bit higher than a straight 12‑month average. Lenders must notify you of changes, shortages, or surpluses.
Escrow changes are usually driven by one or more of the following:
Which value affects your escrow depends on how local taxing districts compute each line on your bill. Many levies in Maricopa County use LPV, while some references to FCV can appear in specific calculations or appeals. Your lender bases escrow on what they expect to pay in the coming cycle, so your next analysis should reflect the latest bill and values.
You might consider an appeal if FCV looks materially higher than recent comparable sales or if LPV jumps and the market data does not support it. You should also act if the property class appears incorrect, such as a rental code on a home you occupy as your primary residence. Appeals have deadlines and evidence requirements, so review the assessor’s instructions and prepare supporting documents.
Expect an annual escrow analysis from your lender. Major county valuation changes typically show up on the annual notice first, then flow into the next tax cycle and your next escrow review. If Tempe market values rise or your property’s use changes, plan for a possible increase in taxes and escrow.
