Suggests for "Comp" software

[Mel Park]

Happy New Year all....

Curious if anyone can suggest the right software for figuring out comps.  Yes, I can guesstimate based on previous sales, etc --  but sometimes the same house in the same zip code - can sell for vastly different sums depending on what part of town it is.  Is there software that is mostly accurate for comps?

I'd like to buy a rehab home -- but want to get a pretty accurate read what the house is worth if made ready for sale.  Thanks
