To the original poster, I am a former Fiserv employee, I left about 2 years ago. I have relocated 2 times due to my wife's job. I was WFH during my time at Fiserv (over 10 years) and am still WFH at my new job. We learned quite a bit from our first relocation. The major issue for us was around realtor fees and what you can get for a home in your new location. I agree with a lot of the other comments here, I would not recommend buying a home and I hope if you own a home Fiserv is paying the realtor fees for the sale.
The other major issue for us was the commute time for my wife. Her employer required 3 days in the office and she had about 45 minutes of commute each way. I would recommend renting and then you can give it a year or two and see if you like it. That way you could move again before your child starts school.
If I still worked at Fiserv, the only way they would get me to move would be for VP $$ and personally I would try to go to Texas or Atlanta before Jersey.
I hope it works out for you.
