One way or another, they are building their net worth.Building net worth is how you may possibly retire with fewer worries.

As far as fewer doors and same $ goes...

Relative to surrounding areas, there are substantially fewer distressed owners, landlords, elderly couples, etc. who are motivated to sell.  

With most older people they at some point become a danger to both themselves and others in regards to stove and fire issues.I would tell the family that you will either terminate or she will need to provide a letter from her doctor confirming her competency to live alone.

Another item would be your office location that is not only convenient but has fewer distractions.You can locate your office in your living place if you can close it and not be distracted by personal things.  

You will have much fewer options then.

However after my risk tolerance grew and my business got to the point where I could weather the storm of an extended vacancy period I realized that I like the commercial (retail/office) side much better and over the long haul the commercial (retail/office) units seem to have fewer months of lost rent then their residential counterparts.Let's look at a hypothetical 10 year hold period.Scenario A: You own a commercial space and it sits empty for 24 months.

@Rick Santasiere, @Kevin Hunter thank you, I have set up an LLC for my remodeling company a couple years ago, and I thought that it might be the same steps to form a LLC, or rather fewer steps than I had to take, IE. visit the Consumer Protection Office in Hartford, notify your town hall, and obtain the proper licenses.
