Some things I noticed.
- The H1 on the page is "BUY" and the second headline that actually includes "Apartments for sale in Lebanon" is an H3
- I would put apartments for sale in lebanon as the h1 instead of buy or at least change that line into an H2 and put "apartments for sale in lebanon" at the beginning of the line instead of at the end
- There are no internal sitelinks linking to that page using anchor text other than "Buy"
- Buy is really awful anchor text. Try to find other places on the site where you can interlink with at least slightly more relevant anchor text.
- Your domain authority is still pretty low. Work on getting that closer to 30.
- Almost all of the external links to that page are spammy directory links that are more likely to hurt you than help you. For example: http://www.dmozing.com/Business/Real_Estate/?p=23\. Clean these up.
- A somewhat legitimate link might be http://www.discoverlebanon.com/en/directory/index_v.Homes%20for%20sale_114.html
