I don't leverage everything I have because A) I'm older, and mortality limits your ability to recover from downturns, and B) I don't have much interest in growing much beyond where I am, since leveraging then requires I take those funds and invest them in a smart manner - which takes work and effort. 

The biggest problem with the Core 4 concept in a place like Pittsburgh, where you're routinely dealing with 100-year-old housing stock and a poorly trained workforce sorely lacking in imported professional tradesman labor, is that your  No. 3 Contractor had better be No. 1 on your list and s/he had also better be both closer to a walking encyclopedia of historic building and renovation than a mere mortal, and also a solid rock of emotional stability and professionalism.

On the positive side, there's no overbuilding compared to the rest of the Riviera Maya and the island or at least part of it (hope you're on the right side) is less affected by the mortal enemy of tourism in the whole area, sargassum.

The bottom end of many of the cash flow markets are very very tough to deal with and out of state investors mortality rate for getting completely wiped out is quite high...

Perhaps it is fear of the unknown of what cancer is and the facing of one's potential mortality that got to me.  

Each year, the insurance company takes a little bit from the premium (or the cash value) and puts it into a pool to cover the expected mortality that year.Yes, the cost of insurance rises as you get older.
