There is a huge learning curve when it comes to wholesaling so if you do commit to doing it you should approach it as a five-year learning curve (like any trade or profession) you will need to find a mentor who knows how to flip houses, evaluate renovation costs, evaluate after renovation value, evaluate as is value, find financing, negotiate with agents and resellers etc.  

If that was your intent then you also cannot do a 1031 exchange since the 1031 is allowed on real estate that is "held for productive use in business, trade, or for investment." 

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.  

The cost is immaterial relative to the consequences of mispricing the property.

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

You can get nice returns with relatively low risk.There are no tax consequences for the rollover and all investment gains and income will be sheltered from taxes just like any other retirement account.

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