I recently did 1/2 thick travertine in a small bathroom & regretted it as it did suffer hairline cracks regardless of the solid thick backerboard/cement base its just the nature of the stone & more likely the temperature extremes we had last winter.

There is no thickness left for any additional refinishing.  

That's why the returns always look so good on low priced properties, the increased risk that comes with more drama at that end of the market makes it attractive if you have a strong stomach, thick skin and like roller coasters...Certainly crunch the numbers on your prospect properties, but also overlay things like safety, quality of local schools and overall appearance of the neighborhood, (the things that responsible people care about).  

You need to grow really thick skin.

If you use 3/4" plywood, you'll have a strong, solid-feeling shelf that will look extremely thick from the trim tacked on the front.

There's this house in my neighborhood with thick vines taking it over Angkor Wat style.

I am very thick skinned and I learn a lot through what sometimes looks like arguing.

The shower drains through a thick layer of shells, that goes down the slope towards our garden (away from our house).

It did NOT smell like money.The clothing was piled so thick in the basement that I had to duck to walk around.It's plumbed for a bath but was being used as a work shop or something.

There are huge multifamily properties that were built back in the days with thick walls, flat roofs and high ceiling.
