Please correct me!

There is no specific time for the  engagement period but it usually lasts one year.
After the engagement party the process of dating and getting to know each other begin. There are two official feasts: The first one (invite people to eat). The groom invites the bride's family to his house for  lunch or dinner. Then the opposite happens; the bride invites the groom's family to her house. 
During this period the groom buys a house accompanied by his future wife.< (<font style="background-color: yellow;">I'm not sure if that is what you meant)</font> They also buy (alshabka); it's part of the dowry and it's basically a set of gold or more ( or more than one set of gold).
The bride goes shopping for the trousseau along with her mother and her sisters
When the engaged are ready and all prepararions too.  They schedule the wedding date.
