If its single family I wouldnt bother with a manager but 2 or 3+ tenants in same building I would consider it depending on how hands off you want to be on the tenant issues and how handy you are

Quote from @Luis Cerwin: I have a single family house in Detroit (I'm out of state) for past few years.

The newest outdoor is still advertising 1st month free as they haven't filled up, and I spoke with the climate controlled owner/builder yesterday (he's a pretty big REI in the area), and he made it sound like he hadn't leased a single climate controlled unit since they opened a few weeks ago.I recently purchased a 140x45 warehouse with low ceilings and had debated doing self storage, but my market seems very saturated.

Imagine if you had one single-family home.

In my experience apt. conversions from single family are more prone to noise transmission. 

I was more interested in Fix and Flips or maybe even rentals for single family properties.

Kyle  My father-in-law did this by creating a portfolio that is primarily debt-free single-family rentals in the city he lives in.

I singles out 3 routes, and due to funds limitations I can take only 1.1.

Not too concerned with rent/price ratio on single family homes since none of them are really going to cash flow a ton anyhow unless they are paid off.
