Pulling comps

Hey all
After many months of learning, I’ve finally taken action and started marketing with a game plan.
My question is about pulling comps… Im not a licensed Realtor, so don’t have personal access to the MLS. What resource do you suggest being the best? The free ones I am currently using is realquest express, totalview real estate, zillow, and realtor.com to see similars that are listed.

Is there any resource that is worth paying for and which one?

Thanks!

Online comps are not a good way to evaluate true property value. Your best bet is get really friendly with an investor friendly agent to pull comps for you.

get to know an area really well, if you concentrate on a smaller geographical area you will have a pretty good idea what the house should be worth,of course still pull comps, you want to look at any comps in the area you are working as much as possible,the difference of buying on one side of a major street or the other could mean different schools (within the same school district) and could mean a difference of price,so even if your pulling comps you really need to know the area
