I do know about the digital thermostats that allow you to set minimums where they cannot go any cooler but then how do I make sure they are actually getting the oil in the tank so that heat is running?

I invested in a second property two years ago and making double digit ROI. 

However, there are unique penthouses, gardens, and villas with distinctive designs that are generating double-digit returns.

However, when the "correction" comes, and it will because it always does and we are close to the end of our UP CYCLE, property values could (and probably will) drop double digit percentages.

Both Denver and San Francisco had the highest double digit appreication in the last 12 months, with Dallas following closely at 9%.
