There are some things to consider with these types of rentals:
1. Tenants renting a single room are likely going to come and go more frequently so you should expect a higher turnover rate meaning more time and work finding new tenants.
2. Because a single room will be much cheaper than a typical apartment or home, you are likely going to have a larger portion of tenants being people who may have significant financial constraints, poor credit, eviction histories, and in general come with a little more "baggage". That isn't to say all tenants would be like that, just generalizing that at this income level of rental you will tend to attract tenants that demand more time and attention.
3. You mentioned you would live the property so that should make it easier, I would reconsider that it may actually be harder because it will be easier to come knock on your door and get you involved with any tenant disputes. In this case, distance would probably be helpful to let tenants work out disputes themselves like they should.
4. With more rooms comes more income potential. There will be more work to manage a property like this, but if done well you will likely have more cash flow potential.
All in all, it's not a bad type of investment and people need affordable places to live so the demand is there. You would just need to screen very well and be prepared to have a little more work to manage the property than say a single family home out in the suburbs.
