Example 1: www.homesforsale.com/homes-for-sale-boston-homes.html
www.homesforsale.com/homes-for-sale-atlanta-homes.html
www.homesforsale.com/homes-for-sale-new-york-homes.html

would this be the best way to incorporate keywords or should I do it this way:

Example 2: www.homesforsale.com/boston-homes.html
www.homesforsale.com/atlanta-homes.html

Question 2. If I want to target the keyword “Boston motorcycle” and that domain (www.bostonmotorcycle.com/net/org/etc) isn’t available is it better to buy the domain www.bostonmotorcycles.com or to go with www.mybostonmotorcycle.com or some other random prefix.

Which is best if I just want to target the term “boston motorcycle” not “boston motorcycles”?

All of the examples, keywords and domains in the above examples are made up. Thank very much for your advice and suggestions.
