Britton Falls by Del Webb in Fishers, Indiana is the Indianapolis metro's most established large-scale 55+ community — 1,050 homes, full resort amenity campus, and a well-developed resale market. The sales pitch is compelling. What's missing from the sales center presentation is the complete annual carrying cost picture beyond the home price and HOA fee.
This page builds the full cost stack for a Britton Falls purchase at three price points: $350,000 (entry resale), $425,000 (mid-market), and $525,000 (upper tier). All figures use verified Hamilton County tax rates and Indiana homestead deduction math.
The Base Numbers: Hamilton County Tax Math
Britton Falls is in Fishers, Hamilton County — Indiana's lowest county income tax jurisdiction (1.1%) among the five-county Indianapolis metro. Hamilton County's property tax rate runs approximately 1.10% of assessed value before Indiana's homestead deductions.
Indiana's homestead deduction reduces taxable assessed value by the lesser of 60% of assessed value or $48,000, plus a supplemental deduction of 37.5% of the first $600,000 of remaining assessed value. On a $425,000 home assessed at approximately $380,000, this typically yields a taxable assessed value of roughly $185,000–$210,000, depending on the specific assessment year and any assessment cap benefits.

The 10-Year True Cost Projection at $425,000
HOA fees in active adult communities have historically escalated 3–5% annually as communities age and amenity maintenance costs increase. Property taxes in Hamilton County have been relatively stable but do increase with assessment resets. This 10-year model assumes 3.5% HOA escalation and 2% property tax escalation annually.
| Year | HOA Fee | Property Tax | Insurance | Annual Total |
|---|---|---|---|---|
| Year 1 | $3,180 | $2,280 | $2,100 | ~$7,560 |
| Year 2 | $3,291 | $2,326 | $2,163 | ~$7,780 |
| Year 3 | $3,406 | $2,372 | $2,228 | ~$8,006 |
| Year 5 | $3,650 | $2,467 | $2,362 | ~$8,479 |
| Year 7 | $3,912 | $2,566 | $2,503 | ~$8,981 |
| Year 10 | $4,381 | $2,772 | $2,729 | ~$9,882 |
| 10-Year Total (HOA + Tax + Insurance only) | ~$84,000 | |||
Add maintenance + landscaping over 10 years
Adding a conservative $1,500/year landscaping and $4,000/year maintenance reserve (1% of $400K average value): an additional $55,000 over 10 years. Total 10-year carrying cost beyond mortgage: approximately $139,000 at the $425,000 price point.
Indiana Income Tax on Retirement Income: The Hamilton County Advantage
Britton Falls buyers in Hamilton County pay 1.1% county income tax on taxable retirement income — the lowest rate in the Indianapolis metro. On $70,000 in annual IRA/pension distributions, that's $770/year in county income tax. Compare this to a Marion County community at 2.02% ($1,414/year) — a $644/year difference that compounds over a 20-year retirement to $12,880 in additional tax (not accounting for income growth).
Social Security is fully exempt from Indiana state income tax and from all county income taxes, regardless of your location in Indiana. Military retirement is also fully exempt. The county income tax differential matters most for buyers drawing significantly from tax-deferred accounts.
Indiana's Over-65 Property Tax Circuit Breaker
Indiana's over-65 circuit breaker (SEA 1-2025) limits annual property tax increases to 2% for qualifying homeowners. To qualify: age 65+, the home is your primary residence, and adjusted gross income is $60,000 or below for single filers / $70,000 or below for joint filers. For qualifying Britton Falls residents, the circuit breaker prevents property tax from escalating faster than 2% annually regardless of assessment increases — meaningful protection in a rising Hamilton County market.
The new $150 flat tax credit (also from SEA 1-2025, effective 2026) applies automatically to qualifying homesteads. Application deadline is January 15 with the Hamilton County Auditor's office.
