In my home country, Khaled owned the building for landscaping purposes. he wants to travel to the USA. Khaled wanted to sell the building around (10000) . Khaled's friend asked me to buy the building, But he wants to buy lower price than Khaled wants. After two days, Khaled got a new offer from the online market more than my friend's offer by about a thousand. and then Kaled's friend texted him“I have accepted the building's price”. Therefore, Kaled sold the building for the new offer. Did two parties enter into a legal deal? did Khaled have the right to sell the building after his friend accepted the building's price?
