US Retired couple looking to move to Netherlands

We have been to the Netherlands several times and are quite interested in moving there. We have been to Amsterdam, Rotterdam, Eindhoven, Olst, Maastricht, etc. and we particularly liked Eindhoven.

We have pensions for income and savings that would allow us to purchase a property ~€500K. We are both well educated (PhD and MBA) but we would not anticipate starting a business unless it is teaching English; we don’t know if there is a demand for that.

We understand that housing is difficult, cost of living is high and learning Dutch is necessary for citizenship. Are there any expats who have similar experience and/or anyone who can share knowledge about the process?

Thank you in advance!
