Common locations for supply lines to fail are where male threaded galvanized pipe is threaded into brass or copper valve and fitting bodies  (due to galvanic corrosion)  and hot water lines will rust up so badly as to start restricting water flow or begin leaking a decade or two before the cold side fails similarly.   

Anyone interested in STR needs to add regulatory acceptance to their due diligence.

If you want to have a body like Schwarzenegger, does it make sense to go ask the people with bodies like Pee-Wee how to do it???? 

Or other regulatory requirements?

When I dreamed of affluence circa 1991, it included the obligatory hot car (that I can buy a few times over now), lots of cheap women throwing themselves at me (my body would end up weighed down so deep in the Mon they'd never find it, I married a dangerous woman), and a lot of expensive stuff (me, a student of minimalism today).It also occurred to me that if my wife and I had kids, there was no way we could have asked them in 2017 to move into a leaking shack on the edge of a heroin ghetto, where a dude got shot just walking home in the alley out back in 2018, where the school system was ranked about as low as you can get for southwestern Pennsylvania (which is really saying something).

And, for many, it's a cycling action much like body builders do of growth, consolidation, growth, consolidation, evolving up along the way. 

Or like I have seen there are a lot of bad actors out there and you will have groups that do this with no intention of every paying on the sellers mortgage and will rip the rents until the houses are lost to foreclosure  when that starts to get acute and brought to main stream something could happen regulatory wise.

The highest multipliers tend to be in the cities with the largest amount of regulatory scrutiny. 

Correct me if I am wrong but Joe Schmoe with no experience and no education can call himself a financial advisor.There is no governing body that administers the term 'financial planner' so I put litte weight into that title / profession, whether it is fee based / non-fee based. 

We must also monitor regulatory changes, tax policies, zoning regulations, and environmental standards that may affect property values, development opportunities, and operational costs.
