I was never an aggressive trader and mostly went into bonds and insured securities. 

For ex. if there are 3 people living in a SFR, it can be written into the lease that the tenants pay the owner $50/month for water/sewer for the first person living there and another $25 for each additional person (or something along those lines).Hope this helps!

For ex: If I get 3 individual properties, I was thinking on partnering with 1 person each on each property to only have to split it two ways.

There is a lot of talk about figuring out where Whole Foods, Trader Joe's, Starbucks, etc are opening up new locations, which would give an indication about up-and-coming neighborhoods. 1.

not sure US would have a tax on that CPA would know.. just use forex exchange and wire the dough

I can’t rent it out on RV Trader or a similar site because I won’t be home to manage it. 

We live exactly one mile from the beach, trader Joe's and a bunch of other stores in the surrounding area, gym, Michael's, new whole foods ECT that we can walk too...

Having said all of that, I think we're in a state of stagnation and not many investments will work out that well, unless you're a trader and you can move in and out of positions quickly.

Larry Goins' How to Be a Real Estate Day Trader is a great read for those interested in wholesaling.

If you have an interest in taking advantage of these common fluctuations then open up a Forex Trading account and trade the spread over longer periods of time (ie. 3/6/12/18/24 months)- not daily.
