If you are talking about the Centerplace at Edison, you do not have to worry. Why? I went over there one weekend and saw hundreds of buyers looking to buy, and some phases even sold out, not yet built.
The most important is that it is right next to Middlesex County College where Middlesex Academy of Science based, this new high school won #1 in NJ Science League Physics competition over hundreds of all other high school in 2007.
Besides, Edison is top 3 safest town in NJ, and most populated Indian township in the US, that is to say you shall get many more people moving in and housing will be getting crowd each year.
I know people renting out their 3br townhouse at Victoria Park for $2500+ http://victoriaparkatedison.blogspot.com/
If yours is new, you should be able to get more if you choose to move up to bigger home and just rent it.
I got lots of info about townhouse and condo market in the area, and when disclose some, people just decided to buy. e.g. I went to Rivendel yahoo group to join the debate of "buy or not to buy", and I was thrown with lots of news links trying to slash the price, but I countered by first hand real time sold info at Edison; I won the debate, and 18 members out of 44 said they were going to buy than rent.
I think your "friends" who scared you were because they watch too much TV and got scared by those who know nothing about Edison, including Greenspan.
Do you know how many Chinese coming to Edison want to buy? Why there are FOUR Chinese schools in Edison. If you know Chinese are the people who often BUY AND HOLD, you know Edison is a place very different than other place, may be another San Francisco.
San Francisco is #1 expensive in the US because so many Chinese families there just BUY AND HOLD. Another closer place is Highland Park near Edison, where most Jewish families also buy and hold, so Highland Park kind of expensive.
Late 2006, Lidia from Remax told me she got a 3br townhouse at Village Pointe http://villagepointeatedison.blogspot.com/
expiring could not sell, and I advised she hold consecutive open house in Thanksgiving time, and she sold it at 4th open house. Before hers sold, she sold other 8 units in the community, now it is almost sold out after dozens sold in 2007.
Why is that? because there are many BUYERS like you, but they are scared by the media, as soon as one went out to buy, his friends will all went out to buy. Also, many first time buyers renting in apartment do not know the area well to make quick decision. Many work long hours during weekdays in Wall St.
For example, one disagreed with me in 2006 saying his friend has unit at Traditions South Plainfield could not sell. So I just went check it out, I talked to dozens of residents to identify the prospective buyers come from Edison/Blueberry Village and Durham Woods, and get 1,000 message out to introduce Traditions at South Plainfield. dozens units sold in 2007, now almost sold out.
So, there are great demand in Edison area, people either buy or rent, once too many people rent, the apartment will be rented out, and rent will jump, so some matured tenants will buy. It is demand and supply.
So far, I have not seen any condo/townhouse can not sell, especially new ones if the owner get Jose 732 979-9100 to distribute 1,000 flyers to prospective buyer communities in Edison.
