I use the term "I" loosely because I had a lot of help.But that's ancient history. 

please don't dredge up ancient threads to respond to?

Found a guy who does a lot of hotels, but the guy looks ancient.

maybe its some sort of ancient philosophical exercise

If electrical is the ancient knob and tube, it may or may not be in need of work in the future.The duplex I am living in now was built in 1880, but all plumbing and electrical had been updated in the last decade so those systems are as good as in a new build.

You'll find a lot of multis built in the late 1890s to the 1930s and those come with all the usual physical plant precautions - knob & tube, cedar pilings, ancient plumbing, etc.RPR is a good tool, but more than that, I'd be looking at Trulia's crime heat maps and MLS rental histories. 

The owners usually slam crappy tenants in and then claim the property is stable after 1 year etc. with minimal repairs and the expensive stuff to replace is ancient.

We have all kinds of proof of change in our planet, from underwater cities, to ancient tropical plants found in the ice on Antartica.

In the ensuing loathsome political rise of the political entity Golden Dawn, an "alt-right" Greek political party with quite conspicuous roots in National Socialism, not even a neo-Nazi but a fully recognizable NAZI party, I was forced to come to some fundamentally ugly realizations about money and power, realizations I had done my best to avoid thinking about my entire life.

My wife wants to retire to a boutique hotel on a Greek island, maybe 20-25 guests.
