Well...two questions here......can you? and should you?
I presume you voluntarily purchased the rental home in 05? Bank did not force you to purchase the property? No one forced you? Your idea?
You voluntarily attended a closing and signed a mortgage and a note agreeing the terms of the mortgage?
The bank (yea the bank) wrote a check and someone received that money under the trems of the note and mortgage you signed agreeing to pay them back.
And now. You decide you dont want to do it anymore. Not your problem? The banks problem? Shouldnt have leant it to you in the first place?
Ok. Well that is an ethical question for you to deal with.
However, apparently you have the means to come up with 100k elsewhere so that you can move on. Stick the bank (and everyon else) with your decision to walk away....and use 100k to purchase something else....and not apply it to the shortage on your mortgage.
You are asking if you will get away with defrauding Wells Fargo. Since you are going to tell them that you cant come up with the funds at the short sale.
Thats what you are asking. Maybe you can get away with it. I hope you dont.
