Where does an investor learn if a certain area of town is "hot" for rentals?

I currently own 2 rental units (Each are 2/1) in a college town. 

Hi, I am a newbie investor looking for my first investment. how is the rental market in west George town, liberty hill area.

A call to a town building department, or an internet search should answer that for you.2) I have found The Journal of Light Construction to be an excellent source of information.

I have saved a ton and am ready to purchase my first short term rental, most likely out of town.

Purchase price: $10,000 Bought the Mobile home as-is from an out-of-town person whose parents, unfortunately, had just passed.

But, this is a small town in the country and this happens to be in my Sister's neighborhood which doesn't happen very often. 

Banks won't lend on it like traditional investment properties and often times unless it is agricultural or recreational, there will be limited income generated by the property until you sell it or develop on it.

In the Vegas area, if you're going multi family it's going to be in not the best parts of town.
