LOS ANGELES (AP) — Former tennis champion Andre Agassi and a real estate venture capital firm have teamed up to form an investment fund to finance buildings for charter schools.

Agassi, who operates an award-winning charter school in Las Vegas, said Thursday the biggest impediment to charter school growth is finding adequate facilities to house students. Agassi’s partner in the fund is a $20 billion Los Angeles-based real estate investment firm, Canyon Capital Realty Advisers.
