California Equity Conversion Guide — Buying in Boise

What Bay Area and Southern California home equity buys in the Treasure Valley — the math by scenario

Why California Buyers Drive the Boise 55+ Market

The Boise 55+ market is substantially shaped by California equity conversion. Bay Area and SoCal buyers selling homes purchased in the 1990s and 2000s are arriving with $500,000–$1,200,000 in net proceeds after agent fees and closing costs. Trilogy Valor starts at $356,000. Cadence at Bainbridge runs $500,000–$700,000. Willowbrook runs $300,000–$400,000. The arithmetic is not subtle.

What makes Boise different from other California equity destinations: Idaho’s retirement income deduction eliminates income tax for most retirees, the homestead exemption cuts property tax significantly, and homeowners insurance in high desert Idaho runs $1,200–$2,100/year — a fraction of California coastal rates. The annual savings compound on top of the equity banking.

What to Watch Out For

California’s Proposition 13 has likely kept your current property tax well below market rate for many years. Your Idaho tax bill will be based on current Idaho assessed value — not what you paid for your California home decades ago. On a $550,000 Ada County home, expect approximately $3,230/year after the homestead exemption. This is far less than current California rates on comparable values — but it may be higher than what you have been paying under Prop 13 on a home you bought in 1998.

California capital gains on the home sale: Federal law excludes $250,000 (single) or $500,000 (married) of gain from primary residence sale. Above those thresholds, federal capital gains tax applies. California also taxes capital gains as ordinary income — consult your CPA before closing on your California home.
