Yes you can, here are a couple of links with reviews from a consumer standpoint on how that works, I have never used the services myself but I have looked into it before.Rock the ScoreRent ReportersRental KharmaRentTrackPayYourRent

I have things pretty dialed in, so it does not consume much time at all....maybe an hour a week?  

It would be a nightmare for the seller to have to give multiple 24-hour notices to enter tenants' apartments for people who are not serious about buying the property and it would be very time-consuming for the sellers, tenants and brokers.

This is obviously much more time consuming and likely that I'll be paying higher prices (since I'd be viewed as a retail customer).So I guess my question is, is it best to proceed by hiring all the subcontractors myself and finding a PM to oversee the rehab, or is there another way to proceed that I'm not seeing?

Splitting land into separate parcels is very expensive and time-consuming.

You can also consider other ideas like buying a high quality air filtration system or suggesting to the tenant that he consume edibles instead of smoking it.

Right now, the most stressful/time consuming part of this whole thing is arranging the cleaning, I’m nervous that one is going to get missed at some point, but I feel like I have to check the schedule daily to stay on top of it.  

Dave Ramsey and Robert Kiyosaki were both helpful for me as well in my journey to being debt-free (consumer debt), quitting a job I hated, and pursuing real estate to gain financial freedom. 

They make terrible, uneducated decisions that hurt the producers and favor the consumers.
