Hi Gravan,
Welcome to the site!
I believe you will find that Nicaragua is a very friendly place to live for you and your family.Since you have experience living in Cost Rica, you will have no problem here. The cost of living is much lower here, and the people are very friendly.
I have been coming here for 3 to 4 months each year since 1996, and will be permanent by the end of this year.
Do your homework and think for yourself. Do not listen to people who send you to sites such as puravidatravels to hear negative comments from people who are simply clueless.
Best of luck, and welcome to Nicaragua!
