Hi. Need a help regarding strata tittle.

I would like to buy a house at kenari court. Im gonna be the 3rd owner of the house. The strata tittle is still under developer.

So the agent said its all up to developer either they want to change the strata tittle from developer directly to me. Or developer - current owner - me.

So, if the developer wanna change the strata tittle from developer - 1st owner - 2nd owner - me. Or is it developer - curent owner - me only? No need to change to every previous owner? How long it will take for me to get the key ya? One year maximum?

Thanks
