Just setup auto MLS email updates.  

What limits did they require you to have on your auto and home policies to get the umbrella?

There were some other little things that annoyed me in terms of completing the tenant profile, but those were minor.Having read the comments on Rent Redi, I thought I would get the auto accounting feature.

Or maybe they just get older, want to hustle/evict/etc less, and have more things in life on auto-pilot, or at least closer to it.

There are areas that I recommend in the Columbus market that I personally invest in like Old North, Old Town East/King Lincoln Bronze Ville, Merion Village, Driving Park, North Linden, Hungarian Village, Bexley, and North Hilltop.

You will have to put money to renovate and you won't generate any income, as these houses are in dying villages that have no economic activities and are very isolated and nobody visits.

For example, at Nordic Village or Attitash Mountain Village? 

That is what I have done in the past but it would be nice to have the tool take into account the max potential monthly revenue and % vacancy and have it auto calculate the management costs based on the revenue and the % management so you can run several scenarios. 

Some villages do an inspection when selling a unit and/or before being able to rent a unit out.  

I recommend getting a Realtor to auto email you new inventory daily and contact multiple property management companies to see if they have any clients selling soon or willing to sell.
