Ok, I have a few comments to add.
The first thing I noticed is the link colors - that pale brown is just TOO LIGHT, the contrast with the white background is not good. Some people with vision impairments may not even be able to see what those links actually say. Darken them up. Same goes for the paler gray text.
Jump menus are generally not a good idea, and definitely bad where search engines are concerned.
The right side column.. is that meant to be above the red line at the bottom of the header ? Just wondering.. if that's the way you meant it
Code.. you use a LOT of 'target=_parent".. you don't need it. The 'target' attribute is also deprecated in XHTML, and using it to open new windows is definitely frowned upon.
You're using PX for your font sizing. Doing so prevents IE users from scaling the text in their browser to something larger than the small size you have defined. Better to use either em or % for font sizing so you're not handcuffing IE users.
Since you're using DW to do the page, absolutely RESIST the urge to set font styling using the properties bar. You want all your styling to be inside your CSS file and not have 'class = stylexx" scattered throughout your document. On the Commercial Properties page, you have a style block stuck in the middle of a div !
Keeping ALL your styles in the CSS files prevents a whole LOT of maintenance nightmares, and you have a large site there.
Flash animation - you are using the <embed> tag, bad news for IE users (again). They will not even SEE your animation until they do the 2-click dance to 'activate' the active content. At the top of the HTML forum is a sticky that has a list of alternate methods to using the <embed> tag. I personally like SWFObject, but all of them are good alternatives.
Overall you did a nice job, I like the design and its reasonably well organized.
