Rules of Thumbs for choosing a target market

Looking at a 100 pad park in the Midwest, it is located in a small town (1,500 people) but the MSA it is part of is 199,899 in population. BUT the population in the MSA is down by 4.2% since 2000 and the closest Walmart is over 15 miles away from park. Park is on City water & sewer. City itself doesn’t have any industry due to size. and its’ population is up by 0.5% since 2000.
I know there are a lot more items I can share, but based on the above would you purchase this park, if so why and if not why not.

Thanks in advance
