I hear you in terms of not putting a lot of stuff out about your personal/professional life on this site, I feel exactly the same way. Obviously you are an excellent communicator in your current profession, but I understand what you mean about developing some long-term sources of income. I’m assuming you’re somewhat middle aged so I get exactly where you’re coming from in terms of future income.
I was lucky enough to find someone, actually through my kids playing sports, a parent, that was already involved with rental properties. This person was already trustworthy, so I was able to build a limited partnership. This is mainly passive income, obviously the rental properties need to be managed, which I definitely don’t want to do, so that cuts into the income but not as much as you would think, especially when you are partnered with other people.
I also know people that have set enough money aside to buy condos that are in a reasonable price range and then turn around and rent those. There are a lot of people that are not in a position to buy, but have to rent. It’s a market that’s pretty hot right now. I suppose depending on where you live though.
