If they won't sign the new lease then the correct answer is them leaving, which will surely be explosive, but you knew that already.Doing business with family is a lot like throwing yourself out of a moving car that you're driving.

Just closed on a C5 zoned property in Colorado Springs on a major street less than a mile from downtown (currently going through growth explosion) and 1 mi to Old Colorado City hub (very popular tourist destination), and a 1200 sq ft commercial workshop(detached) that I can build out a second (interior floor).

If I had a crystal ball to predict future explosive real estate markets, I sure wouldn't tell anyone else lol.With that being said, check migration stats to see who's going where.

Both are important.If you see a negative net migration over the last 10 years, it's probably a pass.If you see a positive net 10-year migration, but a decelerating rate of year-over-year in recent years, that's a sign that it's a maturing community, and till probably not have the same explosive growth it had previously had.Now, ALL that said, if you're talking about net-migration numbers in the single-digit thousands, you're probably looking at too small of a slice of the MSA.

My area has seen an explosion in rent prices and the demand for them is absurd, this is the main reason, why I am thinking about holding this piece instead of flipping it.

Given the explosion in demand on the long island housing market.

they usually don't leave the gas on with a leak because the danger is from gas accumulation starting a fire or resulting in an explosion.

That appreciation here has been nothing short of explosive as a region this year. 

My city has had an explosive year and price to rent ratios are not the most ideal at least from the small amount of properties I have analyzed.

This house had significant fire damage after a large gas explosion.
