Is real estate agent necessary for true value of a home

[Daniel Jones]

So I was driving for dollars in an up in coming (upscale) neighborhood and I came across a FSBO sign. I wrote down the address and did some research on the area and property and I also watched as many videos as possible to determine the offer I should present to them but I keep having trouble finding the value of the home, so I go with my current knowledge call and make an offer anyways and it turned out to be to low! Do I need a REA to give me the comps and value of the property to determine the ARV or is there another way I can do it on my own through other listing sites.?

@Chris Mason So I've learned Chris, but I will just stay persistent and hopefully come across a more motivated seller
