Re: Multiple Websites vs One Website
You cant go wrong with a backup plan, that is if you have the time - one website can probuce more than some agents can handle (Not everyone is skilled in processing internet leads and managing a site) but I think its a great idea.
I have a few clients doing this - targeting either niche areas or different home niches
www.igotrealestate.com and www.lofts-of-minneapolis.com for instance. We get great traffic at the lofts site, and that is a perfect compliment to the main igot site.
As long as you are keeping your content unique, there is absolutely no problem from a SE perspective that I can foresee - and with more than one site, you are in a better position with regards to internet resources. You become a more appealing link partner, you have the option to test new practices on sites other than your main site for conversion or ranking and you can offer a different perspective on one site from the other and test what message works best for your market.
