So I have set up a few companies (a Coop, a non-profit and C-Corp, LTD, B.V.) in the Netherlands just for this purpose. You register yourself as a cofounder/owner of this company (free) and put $4500 in the company bank account. You now qualify for a working visa and can start roaming all over the EU.
I'm a little vague here, because I want to sell you all the advice and legal work to set all this up for $1000. You first get advice from all the other Americans I helped emigrate to Europe over the years. morphle at ziggo dot nl
Without my help it will cost you a few months, three visits to the Netherlands, setting up a company from scratch and hiring a notary, a lawyer and an expat fiscal tax lawyer for at least $19.000 all together.
Are you referring to DAFT? Isn't this only for NL though? Also don't you actually have to show that one of your companies is making money or they won't renew your visa after a year or so?
I must give the standard HN disclaimer though, I can't give legal advise in public, I can not give legal advise here without knowing your individual situation. Talk to you lawyer instead.
The whole point of the turnkey house+land+permits+visa+remote working+infrastructure package we make brochures, a community website and a Coop for is that you need legal support on top of the land buying, (off-grid) house building and electricity/fast internet, water recycling and remote working. We can't give legal advise in public, we can just warn you that is complicated.
