How St. Johns compares with Florida

A city-level home-value series is not available in the current dataset for St. Johns, so this page uses the $375,500 Florida benchmark and labels it as a statewide fallback. That figure keeps the payment examples grounded in published data, but it should not be read as a claim about the price of a particular St. Johns property. Local listings and an appraisal may differ materially.

Property-tax impact in St. Johns

Applying the 0.75% effective rate from county-level data for St. Johns County to the page's home-value benchmark produces about $2,820 per year, or $235 per month. The rate is 0.09 percentage points below the 0.84% median among the nearby cities on this page. The estimate is useful for budgeting, but a parcel's actual bill can change with assessed value, exemptions, and overlapping taxing districts.

Cash needed beyond the down payment

Closing costs are separate from the down payment. Using a planning range of 2% to 6% of the $375,500 benchmark adds approximately $7,510 to $22,530 before moving expenses and cash reserves. Combined with 5% down, that suggests roughly $26,285 to $41,305 in initial cash. At 20% down, the comparable range is $82,610 to $97,630. A lender's loan estimate and the selected property's prepaid taxes, insurance, and HOA charges will determine the actual amount.

Down payment choices at the St. Johns benchmark

These examples hold the $375,500 home-value benchmark, 6.75% planning rate, 30-year term, tax estimate, and insurance assumption constant. That isolates what changes when the down payment changes.

Methodology and limits

The home-value benchmark comes from the Zillow Home Value Index for August 2026 and is labeled as a statewide fallback. The 0.75% effective property-tax estimate uses county-level data for St. Johns County from 2024 owner-occupied housing data and is converted to monthly dollars against the same home-value benchmark. Nearby comparisons use representative coordinates and the same payment formula so the direction of the differences is easier to interpret.

Insurance is modeled at 0.35% of home value annually, conventional PMI at 1% annually below 20% down, and principal and interest at a 6.75% 30-year fixed planning rate. These are transparent comparison assumptions, not live quotes. Actual price, parcel taxes, insurance, HOA dues, closing costs, rate, APR, lender fees, and prepaid amounts can differ. This page does not provide financial, legal, lending, or real-estate advice.
