It will make an increased demand for those rentals near the airport where FedEx is expanding. 

If you've been in an airport in the last ten years, you've probably noticed a big increase in the number of people flying with animals.

My area may be popular for that as it is close to the airport and convention center.

If you need a ride to the airport, some bushes trimmed, sprinkler system installed, someone to meet interview potential tenants I want to be your guy! 

Oh and Grand Rapids has a pretty sizable airport.

I have done some research it ain't in the best area but its less then an hour from the airport there's lakes and other attractions around the property.

And if you are in country with some visa after they nail you they may escort you to the airport!

I figure that area might be solid not only because of proximity to Balboa park but close to airport downtown etc.. and walkable to lots of restaurants making it vacationer friendly even if not like PB, La Jolla etc. right on the beach...2) also, are there decent websites or services that can give one typical expected incomes nightly ?

Now I'm looking at places like Little Rock AR, Shrieveport LA, Tulsa OK, smaller places near an airport.  

The first is in northeast Birmingham, starting from the airport in the south up to Center Point and Pinson in the north.
