Keep Buying or Pay Down?

[Josiah Cooper]

Hello BP community! We are currently investing in multi-unit (4plex) properties that range anywhere from $60-120K. Our goal is to obtain 40 of these properties within 20 years and hold them. We obviously want to be as efficient as possible and get to our goal as fast as we can. My question is this: should we pay off a few properties up front to generate more capital for future investments or continue to buy units until our goal is achieved and then worry about paying the notes down? Thanks again for all of your input!
