I know that Alabama’s unemployment rate drops to historic low.

You’ll want to review historical occupancy for both sides.

Other things to consider: Look at historicals, is it at an all time in terms of occupancy?

Some keep the water in landlord's name and build it into the rent based on historic usage, and hope that water consumption is not too excessive over the historic usage.

This one took some research, and many lesser men have failed to connect the historical dots.

I have heard from many commercial contacts that some of the markets are soft and couple that with rising rates, I personally would prefer to leverage my residential properties as those rates are still historically low and you can fix the rates. 

One property has a commerical space in the front that historically has been used as a take-out food stand, which could be profitable. 

In addition, Seattle has pretty good historical appreciation which can help with ROI. 

Historically the longer term would favor Cali generally ( major cities). 

As for historic data you can upload that into Quickbooks so you don’t lose it and it will give you the ability to track year over year profit.
