LOCATION & Appreciation: Distance from upcoming large projects?

[Andrew Bissada]

I am curious, when it comes to real estate investing and appreciation, if you know about a big project (e.g. a large company coming to your town), how far away from that can you be and still obtain the appreciation benefits from being near it?

What would be the difference between the following ranges (especially the first 4):

3 miles vs 6 miles vs 10 miles vs 12 miles vs 15 miles vs 20 miles ?

Would there likely be a significant difference between 3 and 6?

or 6 and 12?

or 3 and 12?
