Im curious I wanna know what can I do to profit on the rumors i been hearing of another economic crash.

It makes sense to focus on areas with strong fundamentals and, in particular, population and economic growth rates.You mentioned a few cities I hadnt explored before, so will be sure to check them out too! 

I found some good markets (growing. population, economic anchor, good school district, etc).

Relax and enjoy living in the greatest economic engine on the planet!

Aside from the looming economic correction, if you sell it in the future, depending on when, you'll be liable to capital gains tax.

But pragmatically these(1) are so few and far between that it's not necessarily economical for a lender to specialize in this the way landlord loans are one of my specialties.

You have to ask yourself if economics of buying a house vs renting for few more years until the housing market softens make sense.

I find this to be the safest and most economical use of my money.

Right now there are very little distressed assets, making this time in the economic cycle a difficult one to find great deals, and especially with foreclosures. 

Most people will define a good market as one with a strong job market(i.e big name employers that employ white collar jobs, as these create the most secondary employment), a growing population 10% or greater, low crime, economic engines, etc.
