What should be the Ideal Strategies in real estate?

What should be the Ideal Strategies in real estate?
I need to know about the Sales strategies, Marketing strategies and Leasing strategies (all separetely) in real estate market.
An interviewer asked this question to me few days ago. I had responded it positively also. But somewhere I feel, I could have been better answering this question. Hence, asking you all.
Seeking expert's answer. Thanks.
