Tannu or Malna -- or whoever you are -- it's not necessary to change your name for each post.
Which location do YOU think will give you a random sample? Why? We'll be glad to comment on your answers.

Can you see any bias caused by any of the choices? In terms of home ownership, which would be most random? Do you know the definiton of random? In terms of the population, all subjects have an equal chance of being included in the sample. What population concerns you?
I hope this helps. Thanks for asking.

Most people in a street near an apartment complex are probably renters.
