Want to find out the estimated value on a property I plan to sell

[Lisa R.]

Hello – I will be in possession soon of a property that I plan to sell. Of course, I can see the estimated value on redfin, Zillow… But I think they are not taking into consideration the fact that the two homes on the property really just need to be torn down!  is there anyone on here who would be willing to give me their opinion? 
Thank you so much!
