The postings on Trulia are not maintained as well as we would like; they can be ACTIVE, but they tend to be either SOLD or PENDING because the Market is going so fast now.
I like it when a Buyer ask to see the LISTINGS that meet their parameters; Price, Location, Bedrooms, Square footage, etc.
Then I e-mail them possibles and we can narrow down the choices.
Good luck and may God bless
Your best bet would be to work with a licensed realtor to obtain the most accurate information regarding these listings. I am a NYS licensed realtor in Staten Island and would be happy to help you if you'd like my assistance.
