I was having trouble lease a vacant space when a roofing company that bid on some of the repairs saw the space and asked about trading rent for roofing work plus some additional money on certain phases.  

china has new bank transfer system to compete with the SWIFT system so that they can get away from the dollar, supposed to be finished september 2015russia has been purchasing gold in record levels and trade agreements from other countries are now being done outside the US dollarJade Helm occuring now which ends this september on the 15th.

The ones that do are the ones that got in early (not because of the stock market but because they had the means to move the market), and even with a 30% drop, is still looking at a portfolio of 120% growth over the last year (I'm just talking about numbers based off the shanghai index).Of course the wrench in the works is the Chinese govt that has imposed all sorts of trading regulations to halt the fall of the market. what that is going to do to the situation, no one knows.

Sales info is generally public or can be obtained from a Realtor or website.  6-7-8-9-10 times rent and now they are trading at 15 so maybe the market is overpriced or maybe knowing market players are anticipating strong rent growth.  

Are you holding them long term, or plan to sell/trade in the future anyways (where 10 years is all you need)?

Once you own it, why trade it in for over priced properties?

This is a deal where I might be able to trade out of a few SFRs where my basis is $120k and I'd be buying for just about land value with room for expansion.

., but require the higher risk trades like roofing, carpentry, to carry their own policy. 

I took three years after High School to trade stocks with my father with no raging success or failure, just b/e.

One month's vacancy, with associated turn over/repair costs will equal about 2 years or better of the "discount", a good trade off.
