Market Knowledge - How to evaluate a market

[Bria Johnson]

Hello! I am so stuck on which websites I should use to fins my market research. I have used so many sites and still do not know which one is the most accurate for each metric I need. I would like this information for specific zip codes versus the state or the city. Please help me and tell me which website you use for each 1) Median Sales price for  specific amount of bedrooms/bathrooms (ie: median price of 3bd/2ba) 2)rental ranges 3)economic development - is it growing, declining, or stable? 4)Interest rates 5)market demand - buyer, seller, flat? 6) average age 7) avg DOM. Thanks in advance. It is overwhelming being a newbie. Any advice anyone can give about studying  a specific zip code will be so appreciated! THANK YOU!
