St. Johns County · Local mortgage guide
A growing county calls for a mortgage plan that sees the full picture.
Builder contracts, completion dates, incentives, CDD assessments, HOA dues and future property taxes can materially change the purchase. Bring them into the plan before you choose the loan.

- New construction timelines
- CDD, HOA and tax planning
- Move-up and jumbo buyers
Before the tour gets serious
Build the plan around the place.
St. Johns County stretches from coastal and historic communities to large master-planned developments and rural areas. Buyers may encounter builder contracts, community development district assessments, association dues, flood questions and property-tax changes after purchase.

The St. Johns County Property Appraiser provides a purchase-based tax estimator. Homestead exemption and Save Our Homes portability may affect eligible owners, but should not be assumed in a preapproval without support.
Coastal, Intracoastal and flood-prone locations may create different coverage needs than inland communities. Roof age, wind mitigation and construction details can also influence availability and cost.
Condo and townhome communities can differ in ownership structure. Project documents, insurance, budget, reserves and litigation may matter under the chosen loan program.

Rusty’s local mortgage perspective
A preapproval should prepare you for the property—not just produce a number.
In St. Johns County, the advertised payment and the real payment can be different once taxes, CDD assessments, HOA dues and insurance are included. I help buyers compare the full financing package and keep the builder timeline connected to the loan timeline.
I will help you understand what may affect the payment, what documents could be needed and which questions deserve answers before closing pressure begins.
Meet Rusty →Questions buyers ask
Local questions deserve useful answers.
What is a CDD?
A community development district may collect assessments that appear on the tax bill. The amount should be included in payment planning.
Why might my taxes be higher than the seller’s?
A sale can reset assessed value, and the seller may have exemptions or Save Our Homes benefits that do not transfer automatically.
Should I use the builder’s lender?
Compare the full financing package, including incentives, rate, fees, cash needed and long-term payment.
