Whatever you do, do not pay for Realty Trac!
Finding any homes under 300,000 in Cedar grove will be a challenge............there are more in that range in Parsippany, but not a huge amount.
Are you aware that short sales can be nightmare transactions, and not often the bargain some think they are? They can take months and months, and some never wind up closing.
Foreclosures are a bit easier to navigate as the bank has already taken over the home..........please know that all of those homes are sold strictly as is.
I hope you have a solid down payment and have been pre-approved for a loan.
I strongly suggest you find a local agent who can help you put this in perspective. There are not a lot of short sales and foreclosures in the areas you have identified, in your price range, so you may need help with this.
Feel free to call me!
