It's nor clear to me what exactly are your research interests, so I guess it will be hard for anyone to answer it effectively.
When I see asset pricing, I usually associate it with the valuation of financial assets like shares of a company. In my classes related to asset pricing, I think I never saw it applied to real estate. However, it CAN be associated with things real estate too, even if it's not the most typical application. It is probably a very interesting area with several research gaps.
If you are interested in the financial side of real estate, I think Finance would be the area of specialization. But remember that several specializations may study real estate from different points of view (Economics, Accounting, Marketing, Engineering, Architecture etc). So, what do you want to know about real estate?
So, my suggestion is that you look for academic papers and articles which are a match to your specific interests in real estate. Then, check the authors of those papers and see if they are from the department of Finance or some other department. Then, you will be able to tell which journals, professors, departments, and schools are expected to be better able to help you in your research interests.
