Rudy purchased a $7\mathrm{.}5\%$ coupon rate bond one year ago for its face value of $$100.$ He bought the bond just after the coupon date. Yesterday the bond paid its annual coupon. The bond currently has $19$ years until maturity and has a yield to maturity of $7\mathrm{.}253\%.$ If Rudy sells the bond today, then what is his return for the last year?
