Self-Storage facilities around Hunstville. Saturated or growing ?

[Bharath Mun]

My partner and I are looking at self-storage facilities around HuntsVille area. I understand this asset class was hot few years ago. Is it too late to invest in this space ? 

I am mainly looking at outer areas such as Decatur, AL. On that point, I see Decatur population has ups & downs over past few years. Not sure what the reason was for the downward population until 2019. However, I see an uptick of numbers over past 2 years (assuming online census data is accurate).

Is it a good idea to buy commercial space such as storage facility in Decatur? If yes, any particular areas to absolutely avoid ?
