Local market and labor

Most Naperville homeowners finance renovation projects with a mix of cash, home equity, and dealer financing.

Home equity options

Napervilles median home value of $450,000 means most homeowners with a few years of equity have $90,000 to $180,000 of tappable equity. HELOCs and home equity loans are typical funding sources for projects above $20,000. HELOC rates trend in the 8-9% range as of 2026.

Personal loans

For projects under $30,000, an unsecured personal loan often makes more sense than a HELOC because closing costs and timeline dont favor home equity for smaller jobs. Personal loan rates run 9-15% depending on credit.

Local rebates and incentives

ComEd offers rebates for ENERGY STAR-rated upgrades. Combined with federal IRA tax credits, total subsidies can reach $1,500-$5,000 on qualifying projects.

0% dealer financing

Cabinet manufacturers, window companies, and flooring retailers often promote 0% promotional financing for 12-24 months. Read the fine print — interest is typically deferred (not waived).
