If memory serves, our vacancy got up to about 5% a few years ago, but very temporarily. 

Maybe there is a memory leak?

It's been a long time, so my memory is a little fuzzy, but it seems like we may have also offered a credit on their next month's rent to offset the higher cost of utilities during that time as well.

Here is a diagram to help you in the asset protection question:

People have short memories and think stuff like that will never happen again......personally I would never buy in those areas unless I'm flipping it and moving on.....no way would I buy a long term buy and hold there.I just sold my property in Kingwood.....flooded all around the neighborhood but not near my property...it was a stressful 2 weeks..... really don't want to do that again....dodged a big bullet with no flood insurance and I'm not counting on dodging mother nature again

BTW, this is all from memory, it's been a while and requirements change often.

The one that is 13, 125 Sq. feet is a corner lot located on the intersection of veteran's memorial Dr and Elm street, with a view of the river.

While there are fix & flip opportunities there, the market to a larger extent is very active between Memorial Day and Labor Day. 

A tenant called me the Friday night before Memorial weekend on an AC issue that I feel they should have known about the day before or at least earlier that day.

The hit jogged me just a little bit and added just a couple more things to my trauma list as a child. for the next couple of months i began having memory flashbacks to memories that as kid were suppressed.
