The area elementary schools in the Irvington area range from 4 to 8. So some are much better than others.
Overall, home sale do well (in a regular market) and some schools do well. So shop around to see which schools are better for you. There are many neighborhoods also, since I was born in Fremont and selling homes here for 23 years, I'm sure I can find the right house for you.
I would be happy to help.
