Maybe you would all push against this and feel that it simply isn't worth the effort, but I think it's an interesting problem to work on.  

If you are looking for a more passive investment, a turnkey SFH may be a good option, as it will require less time and effort to manage.

So the following breakdown: Day 7- Courtesy "you need to pay your rent" notice goes up (both posted on door and regular mailed) *records are kept of mail date/location and photo evidence of notice posting*Day 14- "14 Day notice to Pay or Quit" goes up (posted on door and mailed both certified and regular) *records are kept of mail date/location and photo evidence of notice posting*Day 28- Eviction officially is filed with attorneyBy this time we hope that the tenant has made an effort to pay but if they are unwilling or will not communicate with us, we have no further choice but to bring legal action against the tenant(s).

That said, if you can fix and flip, why not do that as long as the net is worth the time and effort. 

I'm also looking for a property that can be functionally improved (with as little effort and risk as possible).For instance, I recently did a rehab on an 100+ year old house that had sat on the market because it was on a somewhat busy street, and it had a funky floorplan (but, because it was in a trendy, A neighborhood, I knew that the busy street wouldn't deter tenants...and I knew I could improve the floorplan). 

We will always make good faith efforts to continue to update our articles and resources.

Managing does require effort.  

The law usually says you can hold them liable for rent and other expenses until a new Tenant takes over, but you have to make a "good faith effort" to find a replacement.

I understand some people genuinely enjoy fixing properties and not everybody regrets it.  

No this is the wrong attitude, it takes time and effort and yes, many people do not continue, but those that do and put in the time and effort the reward will be avaiable
