Hey Sameer,
Can you be a little more specific as to what you are looking for. Also, stating extension, traffic prefrence, and language would be helpful as right now most domainers ( given the budget) would need to know those facts to be a lil more helpful.

This doesn't make sense... 'real estate' itself is 2 words. Otherwise the only domain that fits your criteria is 'Realty.com', in which case you should just directly offer the owner a few million bucks
