However, the previous owner hadn't touched the apartments in years (not even a fresh coat of paint...he had inherited the property and the tenants) and everything needed to be replaced. 

Right now the asset is new and fresh.

There will be some days that the tenant will want to get some fresh air into the house.

Now start fresh with you getting new inspection, deposit and rent.If they don't agree, give them a 5 day notice and prepare for eviction.

We have had maintenance complaints all year about various things that we were told would be fixed before we moved in (including a musty smell, screens so we could get fresh air into the house, etc) - all have not been fixed nearly a year later.

I just plan on going in, revamping the place to my standards and starting fresh!!

I think it's weird this program recommended this person as a great riskMedical debts can be more forgive-able, but my problem with this tenant is that they could still file bankruptcy and include any debt to you in that BK.Personally, I'd rather take a freshly discharged Chapter 7 BK over someone with a couple of 25K bad debts. 

From experience I know that military moves are fast paced and stressful so I did a few things to ease their transition;Made sure they left Illinois with keys already in hand even though their lease wasn't officially started so they wouldn't have to go to a hotel or wait to link up with my agent for keys if they arrived at odd hours.Left Directv hooked up and operational so they could keep the kids entertained during unloading.Sent a large fresh fruit and snacks basket from Wine Country Gifts so they could have something immediately coming off of road trip food.Left them some furniture so they wouldn't have to get everything unloaded right away just to have a place to sit and relax after a long trip.Left them recommendations for the best vet in the area in case they had problems with their pets upon arrival.Just little things that I hope made for a little less stressful day 1.

On the upside, while the tenants may have to deal with being the first one to get cable, they are getting the advantages of a freshly renovated apartment.

Oh, and just to add to the negative red flag category - separations or fresh divorces.  99.9999% of these will not stay long and will likely break the lease and likely will also cause drama.
