Ironically, in the local currency of Bolivares, the value of the car went up over time.What are the best hard assets? 

If you know and are really confident in SFRs verse Multifamily go that route for the first one hit some bumps to iron out the challenges you'll have in being a landlord then move into multifamily.

You've asked an ironic question. 

And you can light a gas stove with a bbq lighter (for cooking, not heating/burning the house)If the house is all electric, well you need to bring the “power plant” to the house to run anything...Oh, interestingly some people dont like gas stoves.

If I have 12 feet of cast iron plumbing, would you replace it or line it?

Thank you Saint Cloud huh.... lol, well, ironically that would be myself and 2 others both of which are operating their own non-syndicated fund and will not allow any other in on their deals, they cover every aspect of it. 

It is not like land is in some high demand where it sells quickly and dealing with land is a very specialized field since there are thousands of issues that need to be ironed out before a lot sells e.g. nobody wants to buy a lot where you can't build what you want on the lot because the last blue butterfly in the world lives in a bush on the lot, or the lot is on an earthquake fault, or there is the county will not let you build a structure on the lot more than 10 feet tall, or you cannot cut down a 100-year old tree right where you want your building to go and the list goes on and on.

EDIT:  Let me add that I also look at the age of the property, trying to stay with properties built in the late 70s or later to avoid issues with lead base paint and cast iron plumbing.  

If it's cast iron drains then I'd check for leaks. 

Mow your own lawn, change your oil, iron your shirts, bathe your dogs.
