Do you know your passive income goals for retirement? If not, I suggest you take some time to determine your needs. Based on your needs, you can decide what level of real estate investor you need to become.

I will have a military retirement during my golden years, so I don't require many real estate holdings. However, if you need a pension-like income, then buying an apartment building may be what you require.

The question is if it is better to own one apartment or multiple single-family homes? There are pros and cons to both, and inside I review a few reasons.

However, to truly determine your needs, I recommend reading more books to get super-smart on what time and income requirements best suit your retirement dreams. Passive income is incredible because you can have it your way—with the proper level of knowledge.
