Part of this, in honesty, is from Bigger Pockets since every podcasts preach the same product (multi-family that you can do cosmetic rehabs as your first property that you can house hack).

A couple notes that I am sure have factored into the agent's communication routine.

You have moving costs, and most homeowners spend time and money bringing it up to their tastes/desires, even if its minor cosmetics or furniture.Add to those costs the need to ensure your rental unit(s) are in rentable condition and that you will need to have funds available to bring the unit(s) up to rental condition when you have a vacancy.

In terms of rehab work nothing major, ideally cosmetics (flooring, appliances etc etc) 

The property manager will handle both routine and emergency maintenance, take care of routine inspections, and manage any situations where conflict resolution is required.

If it is livable and the work is all cosmetic, FHA wouldn't be a terrible option. 

Then look for a good deal, like a cosmetically run down duplex in a medium to good area, get into it cheap, do the rehab yourself or hire out to handyman when its above your head, rent, and repeat.

Extensive gut/total remodel or quick cosmetic lipstick on a pig deal.

Then he went out and moved my stuff from the storage unit into my side of the duplex, installed blinds for me on both sides (he didn't trust a tenant to do it, probably smart), then walked both sides and found a few issues and put a work order in for me (small cosmetic stuff), and then he mailed me the keys and closing documents in a box with a bunch of my mom's homemade cookies.

It needs a lot of work, basically everything cosmetic except kitchen cabinets.2.
