98% or even 99% is about as close to 100% as you'll get. There will always be a number of properties that sell without being listed on the net. They would generally be off market transactions or sold after being "just listed". It reminds me of restaurant ratings or even wine scoring. Some guides employ stars like the Red Michelin guide others rank the restaurant on a point scale out of 20. There is one point of view that a restaurant cannot ever achieve a perfect score thus the best score you can achieve is 19 always leaving room for the restaurant to innovate and theorectically do one better. Pierre Gagnaire, famous French chef and Former apprentice with other famous chef Paul Bocuse opened a restaurant in Saint-Etienne in 1992 for which he obtained an impressive 19.5/20 mark in the Gault-et-Millaz Guide and 3 stars in the Michelin Guide.

BTW - have you ever seen a wine given a perfect score 100/100 or would it justly deserve such an accolade ?

So there you have it - property listings online vis a vis restaurant guides.
