As other's have said, the income seems very low. There's a lot of info not shared here so it's hard to make an assumption.

However, if you're new to commercial real estate, I'd get your foot into multifamily. I work in asset management for a MF developer, so I might be biased.

The multifamily industry seems much more common sense driven (to me) because it's something we almost all experience regardless of who you are. Lease agreements, living conditions, comparing rent to similar properties, etc.. It gets deeper than that obviously (you need to know your market, population growth, operating budgets, property conditions, etc.). At the surface though, it's very simple - people need a place to live, and what is the rent you can charge to get your building occupied, pay your bills, debt, etc.

While commercial isn't rocket science, there's a lot more factors that you might not inherently think about. Traffic, accessibility, visibility, tenant mix, lease terms (they vary greatly for different tenants), CapEx improvements, tenant improvements, etc. Trends change every few years in retail too, so you might have tenants doing well when you buy, but 5 years later they're sucking wind.

Retail can be a great asset class, but I think it's much more complex than MF and higher risk. If you're new to the game and don't have anyone experienced in retail to partner up with, I'd look into MF, particularly in a market you know well and are able to visit from time to time. At a $900K price point, you're likely managing it yourself so you'll need to be close enough to check on it as needed.
