If you are planning on selling yourself you will always field a few bad potential leads to find quaified buyers.

Wouldn't be a bad thing to do this full time but taking one step at a time.

In fact even when you hear yes the terms that usually follow are so bad you are going to say no!

You don't want to be buying in a market that you have no clue what the good and bad areas are.

The concrete steps at my rental property have had a bad winter.

@Kris Benson is correct. 7 square feet per person is considered the industry standard for market equilibrium, less than that, the market is considered under supplied (good), more than that, the market is considered over supplied (bad).

Now that might not be a bad thing if I made enough so that I owed more than $7,683 in taxes this year, because it would just even out later.  

Too bad but that's the way it's currently set up and I don't see anything to indicate that that will change.

It's an SFR, roughly 100 years old, with a foundation that is in bad shape.

So selling and requiring a contingency with a floating closing date for you to find your replacement is not a bad thing to explore at all.
