Realtors & Lenders in 250th-Anniversary Cities - July Housing Impact

I am writing a mortgage story on a look at housing markets in four of the nation's cities with a huge 250th anniversary celebration. I seek sources in real estate or mortgage lending in these major cities. What is the housing market like in this city? How’s inventory? Is it a buyer’s or seller’s market? Are the 250th anniversary celebrations affecting sales this July? Please send me a message if you have a source in mind. Thanks!
