Irrespective of whether you claimed it over the years or not.For the past I can't, unfortunately, tell you how to fix this and if it's even possible past the 3-year period during which you can amend your returns (which you probably should do together with a CPA) But what I would recommend is to file for an extension with the IRS so you have more time to have a CPA look into your situation rather than rush into a (mostlikely incorrect) filing.

So, after some incessant begging from me :):)--he agreed to give me 85K more, amend the original mortgage, pledge another free and clear house, and purchase another one with the proceeds.

But you could write an amendment / addendum to that contract adding in that contingency.  

I have a CPA that is pretty good and found us some money through an amendment to our previous taxes but he isn't the best with real estate.

Update on this post...I officially pulled out of the deal this morning after the HOA (even after allowing them an additional week to produce more records) failed to provide the full condo Declaration & Bylaws (just a couple of Amendments).

So far I'm torn btwn two:Offer less with a conversation about the repairs that are obviously needed before it's habitable.vsOffer near asking and then after my inspection "crunched the numbers and the repairs needed and need to amend my offer".My problem is im emotional about it because I want to live in it after some hardcore fixin'. 

I dont have a problem with this but I can't use his form to send in the offer I want to make, unless I add it as an amendment, which shouldn't really be that much of a problem.

I'm thinking I should amend my 1040 but I don't know what strategy to take.I made about $35k in interest from installment sales in 2010 and $18k in principle payments on the sales.I never file Schedule A.What should I do???

I would DEFINITELY renegotiate and sign an amendment to the current lease switching it to a month to month lease before listing the house for sale, which can be cancelled by you with 30 days notice.

I told her I had not and mentioned the reasons (above); I had not received an amended contract or an answer about the $1000 down.
