I lost my rental.

I had found a rental for Jan- March 2014. When the rental agreement came in the mail it was a stock agreement used for long term rentals with a lot of stuff crossed out and the crossed out items were not initialed. I didn't think that was safe also it read weird with stuff crossed out that changed the meaning. Especially as the crossed out bits left parts that in some cases didn't make sense. So in typical me style instead of sending it back for initials, I added an addendum that clarified the crossed up sections. The landlord didn't like that so I guess they sent my check back. I am not at home but in Hawaii so I only found out when I emailed the landlord as I noticed it still showed available on 4 rent.
What should I have done?
