You most likely do not have a case for two reasons:1) First, the statute of limitations, or time to bring a lawsuit, in your state for a written agreement (like a loan agreement) is only 6 years; if the loan was taken out 7 years ago, you have waited too long, since once the statute of limitations has passed, you may no longer sue.2) Whether or not you were given good advice or the right loan for you or not, unless the loan officer and/or realtor misrepresented something material or important to you (such as the rate you'd pay; the structure of the loan (e.g. whether it was adjustable or not); the points or fees) or about you (e.g. lied about your income in helping you take out the loan), they did not do anything legally wrong: that is, if they truthfully disclosed all the critical information and you had the loan documents to review, you had the information you needed to make a decision as to whether you should take out the loan or not--having decided to take it out, you cannot now take action because, in retrospect, it was the wrong decision for you.
