Follow in the footsteps of many others who rapidly scaled up a portfolio of multiple houses, generating thousands of dollars per month in positive cashflow, all utilizing typical high-tech compensation resources like RSU's and bonuses. IMAGINE... Tapping into multiple sources of affordable, quality houses in attractive markets nationwide. Investing with instant cashflow from day one, with no rehabbing or waiting for rents to rise. Getting all the benefits of real estate as a true passive activity; no dealing with tenants or toilets! Being on the right side of inflation, and actually benefitting from it! Best of all, this can be achieved while working a demanding and successful career, using typical high-tech compensation resources like RSU's & bonuses.
