** Morningstar cuts fair value estimate for Australia's Waypoint REIT WPR.AX by 4% to A$2.7/share

** The investment research firm says cut is based on higher long-term capex estimates as the Retail REIT rehabilitates and redevelops its portfolio of petrol stations at a 'faster-than-expected' rate

** Says co's long-term outlook 'challenging' and made worse by the Iran war - high fuel prices and fears of shortages to accelerate electric vehicle penetration and reduce petrol station usage

** Morningstar, however, notes co's medium-term outlook to surprise the market due to solid rent growth on lease renewals, interest rate hedging protection against rising rates and solid demand from second-tier service station operators

** YTD, WPR down 8.6% as of stock's last close
