@Chi SastryYou need to define "good market" Franklin TN for example is the best market in the entire world if you want to live there personally.

Moving on there was something that stuck with me while being here which was “Write your declaration of independence” meaning defining what will set YOU free. 

Here's how you can structure it:Contingency Clause: Include a clause in your offer that states the purchase is contingent upon securing a lease agreement with a tenant within a specified period.Time Frame: Define the time period within which you need to find a tenant.
