With the never-ending changes in our Real Estate Markets real estate professionals are starting to pay attention to the sound of new commission streams of income.

Terms that only the ’smart’ and ’numbers-oriented people Volgins use to determine if a Real Estate purchase is a "Good Deal", or not. A majority of the realtor brethren attended real estate school because they are excited and passionate about the promise of selling real estate and making a fantastic living. That being said "Times are a Changing." Even if you live in a Hot Market where residential real estate sells in 2-3 days there is an old approach to real estate that is growing faster by the day.....Residential Real Estate Investors.
