Is my opinion that working one-on-one with a successful coach that understands how to get you into action and knows your market and knows your strengths and weaknesses, not group but 1 on 1, is the way to go.Group classes are generally very basic and mostly for motivational purposes but does nothing to get your business goingResearch Rich Poor Dad coaching here on BiggerPockets to get more insight as far as the value of their coaching for the money

Two big things to look into is the the leases and deferred maintenance.1) The leases and the strength of the tenants are important to look at.2) How long do you plan on keeping & have a exit plan.3) Location of property is always a important part too.  

Anyway, it's a mess and I don't have the strength to deal with these people.

This is very dependent on activity and the strength behind your offer.

There is no right/.wrong, better/worse only what each individual investor's preference, goals, and strengths are.

Each type of asset has its advantages and weaknesses, and having a mix enables the savvy investor to capitalize on each asset class's strengths and to diversify risk. 

Agree with @Jason Miller, take some amount of blended approach as both strategies have their strengths.

And sometimes the appearance of greater strength is what takes to get an offer accepted.In every state, there are bound to be quirks like that in the local RPA.

Certain people would have their strengths and a network of people know for repairs, etc.

You could easily apply more strength while you have it open by adding support as well.
