But in general I focus on growth markets to maximize my return across the 5 ways investors make money in real estate: natural appreciation, forced appreciation, depreciation, principle pay down and cash flow.

The dumbest thing I’ve ever done was paying off my first two rentals and trying to pay off my primary.

Aside from grass roots networking, what technology can help me find pre-market deals?

These folks have higher paying jobs and many only need a rental for a year or two.

I would check the market conditions and calculate your numbers.

You'll find stuff on the market, you have to be fast.

usually off market, not on.

I'd research how much the rich people from NYC are paying and see what kind of houses they're staying in.

Anytime the government tries to control prices, like they do with insurance in California, the market will react. 

What I meant was avoid markets that are only cash flow markets.
