Pair that with the job and population growth and you cannot afford to invest anywhere else.

@Willie Taylor There are lots of different ways - direct mail, door knock, bandit signs, your website paired with Google adwords, Facebook ads, word of mouth, networking, wholesalers, other investors who may pass on properties that don't work for them.

I also decided only to purchase places where historical currency valuations for the USD are to my advantage. 

Whatever the bank accepts as currency, fine!

You will spend an hour going to the store to try on a pair of $100 shoes, spend the time and effort when you are spending $25-$50k.

All this paired with the financials will help you make a good decision.If you would like to connect; my wife and I would be more then happy to talk with you and your husband more about this!

Since I live in Italy I could not afford a high risk, A travel to the US could cost me thousand dollars.Since the US real estate is not my core business, a lower ROI and having an asset in foreign currency is fine for me. 

My personality type pairs well with someone who is reliable, focused, and great at planning.Ok great.

A house is not currency.

When you consider the 5 currencies, you will spend at least one of them to get another.
