PITI Estimation: Taxes, Insurance, HOA Without Guessing

Practical methods to estimate property taxes, homeowners insurance, mortgage insurance, and HOA dues for accurate front-end DTI.

Taxes

County mill rate × assessed value ÷ 12 for monthly estimate.
Use a buffer for reassessment after purchase.

Insurance

Get 2–3 quotes; older homes and weather risk areas skew higher.
Deductibles and coverage levels change premium — model a range.

Mortgage Insurance

Conventional PMI depends on LTV and credit — ask for a quote band.
FHA MIP is programmatic; use current tables to estimate.

HOA/Condo Dues

Use seller disclosures or contact the association for current dues and any special assessments.

State-by-State Starting Points (Educational)

High-tax areas: model 1.5–2% of value annually for taxes.
Low-tax areas: model 0.5–1% of value.
Insurance corridors (coast/wildfire): widen your premium range by 25–50%.

These are starting points; always get local quotes.

MI (PMI/MIP) Nuances

Conventional PMI may drop off when LTV reaches program thresholds.
FHA MIP duration varies by LTV and program year—account for this in long-term budgets.

HOA Dues & Special Assessments

Ask for the most recent budget and any planned special assessments.
Condo insurance master policy can affect your personal HO-6 premium.

New Construction & Reassessment Gotchas

First‑year taxes may be based on land only; year‑two reassessment can jump your escrow.
Budget an extra cushion for the second tax year.

Flood & Wind Considerations

Flood insurance (if required) adds to monthly; verify FEMA zone and elevation certificates.
Wind/hail deductibles and discounts (e.g., fortified roofs) can change premiums.

Utilities Reality Check

Ask sellers for 12‑month utility averages when possible.
Factor commute/parking costs for true affordability.

Seasonality in Utilities

Model summer/winter peaks separately; budget the higher of the two.
Old windows/insulation can dramatically change heating/cooling bills.

Insurance Discounts Checklist

Bundle auto/home, monitored alarms, newer roof, wind mitigation.
Raise/lower deductibles thoughtfully; confirm lender requirements.

Tax Appeals (High Level)

Check assessed vs. market value; appeal windows are time-limited.
Successful appeals can reduce escrow over time — not immediate.

PMI Removal Path

Track LTV; request PMI removal when you hit program thresholds.
Some servicers require a new appraisal; budget that cost.

HOA Reserve Studies

Ask for recent reserve studies; underfunded associations can mean higher special assessments later — plan your affordability around potential increases.

Exemptions & Occupancy Effects

Homestead exemptions can lower taxes for primary residences.
Non-owner-occupied properties may carry higher taxes/insurance.

Master Policy vs HO-6

Condo master policy covers shared structures; HO-6 covers interior/unit.
Review deductibles; special assessments can arise after claims.

Property Age & Materials

Older roofs, plumbing, or electric can increase premiums.
Wind/hail-resistant materials can lower insurance costs.

Insurance Coverage Glossary

Dwelling: Structure rebuild coverage.
Liability: Protection for injuries/claims.
Loss of Use: Temporary housing after a covered loss.

Hazard Zone Checks

Flood zone (FEMA), wildfire risk maps, wind zones.
Special hazards can add riders or separate policies.

Utility Estimation Tricks

Estimate by square footage, age, climate; ask for 12-month history if possible.
Electric vs gas heating shifts seasonal costs — model both.

HOA Document Pack to Request

Budget, reserve study, recent meeting minutes.
Master insurance certificate; special assessment history.
