Stay away from TRANSLATOR Plugins..OMG, some of my clients have lost customers because these plugins don’t translate the right way and in the translated language, something offensive is said..
If I were you, I would set-up a special page for this property and use the Google Translator tool for each language. Pick the top 10 languages in Europe you believe your property would sell in, write the ad copy in spanish and translate each page into the native language, from spanish, using this tool.
NONE of my clients have had issues with the translation of this tool. You are correct, even in non-difficult financial times, Real Estate, Insurance, SEO and Affiliate Marketing are some of the most competitive markets on the web.
