Dan provided knowledge on purchasing and financing houses, the rental market in NYC, and the long-term viability of each unit we viewed. He also taught me the technical aspects of renting units in a building that you are living in and helped me set up leases. Due to his advice, expertise, and coaching, I was able to progress from looking for the simplest and easiest condo I could purchase anywhere in NYC/BK to purchasing a four-unit brownstone in Park Slope that I will keep forever and live in it and/or be able to rent and make a profit. Dan guided me to the optimal house, in the optimal location, with the optimal long-term investment potential.
