A better strategy from an education and finding interview guest standpoint is to listen to other podcasts and reach out to apartment investors who were interviewed. You know they are both apartment investors and willing to be interviewed.
Hey John - many of the people you want to interview have done interviews on podcasts already. If your goal is simply getting answers to the questions you listed, there is an easier approach. However, if you're looking to use this interview for content or build relationships with these people, then it may make sense to go down the path you're pursuing.
@John E. Best Real Estate Investing Advice Ever and the BiggerPockets podcasts would be good places to start.
