You can schedule a vacation, fly to the ships location, land, hop on board, and tour the coast of SE asia, for example, by luxury of cruise ship for a few weeks.

But consciously saying I am going to take a low rate of return believing that the property I am buying or the city I am buying will go up in value is not a smart investment strategy.I have not seen that per se in this forum, but the conversation has tilted as it usually does on this site to strategies that are more prevalent like SFH investing.No matter what the strategy is, it is always smart for investors with this kind of money to exercise patience, educate themselves on opportunities and invest in the way that they are most comfortable - IMO.

Lauderdale and Miami.As for someplace the SE is high I think it can be considered above average but I'm no expert in this field.

Texas and SE.

Let's suppose you had that income, in this case contributions to your Solo 401k plan can be made from earned SE income, you can not use your W2 income to contribute into Solo 401k. 

What's a good way to do that without getting "double taxed" (paying SE tax on after tax W2 money)?

@Chris Heeren - you are correct about getting hit with S/E, so if you have a of of properties and depreciate them correctly its possible.

You buy for cash flow, not appreciation or economic growth per se. 

In general, the SE valley has some better options (Chandler, Gilbert, Queen Creek, San Tan Valley). 

Personally for me, I would not get a turnkey company per se.
