ramifications from out of state foreclosure....?

HELP! I own a condo in Weeki Wachee, Florida; purchased it 4 yrs. ago for 100,000; put 25,000 down and renovated and decorated it. I assumed I would be spending my senior winters there, but alas........My living circumstances have changed and I needed to purchase a home in New Jersey last year, couldn't find a job and can't afford both mortgages. (My primary residence has always been in NJ.) It was listed for rent but it didn't happen; it went on the market as short sale 4 months ago listed at 40,000; the bank countered at 44,000, deal fell through. I haven't paid the mortgage on the Fla. property for the past 4 months, but I've still been paying the maintenance fees and utilities. I can't even do that much more.....the balance of the morgage is 70,000. I need to know if I "walk away" would any attachments of liens be placed on my NJ property and/or any savings I have been living off.....no one seems to know for sure what will happen......can you help???
