Size of the property does not really matter; the bats will work the whole neighborhood.
For bat houses, the bigger the better. If you want sufficient numbers to help with the insect population, you want a box big enough to attract females and pups. The males might use a smaller box but they don't roost in large numbers.
Here are the guidelines from Bat Conservation International (PDF Download)
They recommend 20" long x 14" wide at least (depth front to back is not as important, as there are partitions inside 3/4" to 1" apart, as many as will fit the depth you have.)
With that in mind, if I had to pick between the two you show, I'd go with the first Nature's Way model, because it has the bigger roosting chamber of the two, though it's actually still under the recommended size.
The rest of your questions regarding placement are addressed at the bat conservation site, too: http://www.batcon.org/resources/getting-...bat-houses
