The accusatory tone is somewhat offensive and disruptive. 

I want to make sure that I post in the proper forums as not to be disruptive.

When looking at the house pay particular attention to the location of plumbing fixtures and any other lines (gas, electrical, ducting, etc) as they will be more costly to move than they would be with a basement.Additionally, if the building is older and has cast iron or copper DWV, you may want to have the lines scoped to ensure they are in good condition (as it can be a big, disruptive job to replace bad lines).

That's an amazing return without the work and life disruption.

The tenant has told me when I am on the phone or with a client it can be disruptive when she is with a client.I am sure the sound is going through the suspended ceiling space.

If your injection starts adding up to $200k for the 2, and let's say there is no further significant disruption once new tenants are settled, do the 2x returns EASILY total $10k net per year (ie. rule of thumb, are they grossing at least 10%/y)?  

I still keep my license since it's already active but don't have time to represent clients anymore.For a real estate investor it might be benefit for reasons @David Hutson had mentioned, but if you want to do real estate sales full time it seems to me the industry is changing very rapidly due to disruptive technologies and websites like Redfin, Zillow, etc., which I think will be a big challenge for new agents with no established client base. 

I think its an industry ripe for disruption.

Our tenants' lease in Fairhope #1 had another 8 months on it when we moved to the area, so we had planned to rent Fairhope #2 for a year and use the 4 month time frame between the end of their lease and the end of ours to make a few improvements to it so we wouldn't have to disrupt our lives while living in it. 

What you decide to do depends on a lot of factors including if you are using financing (may want to minimize disruptions to cash flow), if the current tenant is at market or below market rental rates and a whole host of factors, too many to list here.The one thing I would not do is ask the existing tenant and open ended question like "what would you like fixed?".
