That photo is from a newly renovated house here in Atlanta, that was just listed.So, obviously there are some rehabbers that think they're adding a gteat feature, but aren't thinking it through.

You need a good source for local landlord tenant laws, a  reserve account for the unexpected, setup a payment tracking system, find a handyman, set expectations with your tenant about what constitutes a valid emergency, have the tenants sign a "walk through" list with photos of the condition of the house, make sure they have renter's insurance, 

Photos in the comments if I figure out how to insert them. 

That photo shows the landlord is not doing what he is supposed to do.

In those days, if an appraiser could find as many as three truly comparable sales reflective of typical prices that were also arms-length, it was pretty much a miracle.Fast forward to today, where the MLS is on the internet, with interior photos of the property, with assessor data readily available, with GIS systems etc. etc.

You can always use prior photos from when it was vacant.

Apart from photos, I was thinking about having a letter from the real estate agent who listed the house 2 years ago (and who is re-listing it now) give me a letter stating that the damage from not watering was substantial from the last time he saw it.Thoughts?

Pictures - There should be an extensive gallery of photos, in HD, and not taken on a cell phone.

I set the expectation up front that the inspector will provide a full report and a detailed list with photos and video in addition to making himself available for questions. 

Are their listings detailed with good quality photos?
