you need to get a general area, where you would feel comfortable driving to and from everyday. Family or Friends....ETC.
For $300k you have many options.
My first question is are you pre-approved for $300k??
If yes...then look up to $325..... if a house is over priced it will sit on the market for awhile and may eventually come down in price.
Keep Union County in Mind... its has many GREAT AREAS.... Exit 135-140 on Parkway.
You can find a GREAT HOUSE for that price range in Keniworth, Roselle Park and Union
All at exit 138-139
