I use DealCheck right now and it is extremely convenient for quickly evaluating properties.

Owning multiple properties in the same area or block can be a convenience in managing the properties.

You could look into submetering.The real question is how much are you willing to spend for convenience which varies person to person. 

They appreciate the peace of mind and convenience of having a professional showing their house for them.

Will it be that any one of you can do anything, for convenience sake?

Philadelphia is different in that it's in that convenient location in the middle of NYC, DC, Wilmington, and all of NJ.

The phone is there for my convenience not some insurance or window replacement solicitor's convenience. 6. 

If you want to absolve yourself of liability tell them that it is there for convenience but you won't repair or replace. 

Reading J Scott's book on rehab costs helped tremendously on being realistic with your numbers.Stayed frugal with lifestyle costs, kept wholesaling for around 2 years before buying a fix and flip, then rolled my profits from that into my first two rentals which were conveniently on two side by side lots and sold in one transaction. 

I also will not manage the properties that are not conveniently located.
