How to Access Market Data

[Brad Fallon]

Hello BP, 

I am in the process of assessing several cities in my area in Maryland to figure out where I am likely to find the best ROI. Since I am not an agent, I do not have access to data on the MLS and am doing my best to find other ways to collect. A local Long & Foster in my area posted this document which shows a lot of the data that I am looking for including the number of units sold, the median sale price, and the months of supply figure. I would also like to find out the type of house that is selling and the property details including the number of bedrooms and baths. 

Is this data only available to obtain through the MLS? Or is there some other way for me to find this information and analyze multiple markets as I continue to search for deals?

Thank you!

Brad
