Options on property - are they halal or haram

I am looking to buy a call option to purchase a property from the ultimate seller at a specified price after a certain period of time. Once I option the property, my business partner seeks for a Development Approval from the city council, upon receiving that we revalue the property and on sell it at the revalued price to an ultimate buyer who might be a developer, or a construction company, or a hedge fund. We pay the owner of the property the specified price and keep the balance. Me and my partner then split the profits at are our agreed percentages.

Is this acceptable

Wa alaykum salaam,

Options on property acceptable unlike options on financial markets which are used as derivatives.

Allah knows best

Would this come lease option
