For example, it is hard to achieve more than 10% net rental yield in any continental European country.

It is possible in most European countries the only problem is the RED tape here it is a killer and if anything happens were the renter is concerned it can take up to five years to get them out.

We have everything from inner city junk to multi million dollar private estates like most major metro areas.

I realise that you have California and Florida that matches Spain's climate, but the culture naturally is different here, and that's what makes it interesting.US citizens can of course invest here the same as any European.

It feels as is Europe has very different numbers.I would love to find people who can help me better understand the European and Dutch markets versus the US market to see what really works here.

@Greg Teamann Vacancy rate seems low - I suggest to use a minimum of 8% (unless you have landlording experience and have a make-ready team in place, capable of turning a house in matter of few days).Repairs depend on the age and condition of the house, and the rehab you put at the beginning. 8% sounds about right, if you took care already of most major mechanicals.

Maybe compare stocks to commodities or European stocks or Japanese stocks- something that is more similar in risk and in payout method.

@Sam Wydner The 1% rule doesn't apply in most major American metropolitans with population and job growth.

You might also check out San Luis Potosi and their waterfalls and Old World European sections.There are a lot of options out there. 

California is a negative cash flow state as is most major cities in the northeast are as well.
