I previewed the site you mentioned. There are many foreclosures listed for my area. I cross referenced the listings on the site with the local MLS. There are a high percentage of discrepancies primarily due to the homes not being on the market any longer.
Though the prices and much of the details seem accurate there were homes listed on the site that I did not see on the website. I say this to encourage you to find an agent to work with who will help you meet your purchasing goals. Whether a purchase to reside in or an investment I encourage you to reach out to an agent from trulia to help you find foreclosed home. If you find the "deed holder" they will direct you to the listing agent to write up an offer. In that case you will end up using the seller's agent to purchase the home either way. So you're going to utilize an agent to purchase a home regardless.
A secondary question is why do you want foreclosed homes?... more
Your home was not sold to fnma, chase was the servicer of the loan and fnma was the investor. A bankrutpcy would do little but stall the process. IF you have documentation inidcating a workout was approved then you might be able to get your property back, but if no paper trail it is unlikley FNMA will entertain a workout. In NJ the foreclosure time frame is long and fnma will think you had a long enough time to reslove the issue.
