Though the 40-50% number has been used in many examples in this board, I've yet to see any data that backs it up.

Realtors in my area tend to only provide MLS data, which is incomplete.

Some do, but to get title free and clear is a little extra work, time and money.I advise people that tax liens need to be looked at as a savings account that might end up in owning some property at a later time.That being said, John Beck is basically useless except for piqueing one's interest in tax liens.

I know of companies in PA grossing around 250k that is well off but companies in New York that are just getting by.2) The extra tax isn't going to come out of the business owner's pockets.

You have access to your data from anywhere.

However, when someone is able to buy a home and change their life, there is no better feeling in the world and it makes it all worth the extra effort.

Science teaches you how to analyze, problem solve and present data in an unbiased manner.

They simply take public data and merge it with MLS systems on a computer system.

Do you have any data about what comparable units actually sold for?

This is a moot point as the actual "extra" commission is typically so little after splits with the broker, and uncle sam.
