Take my reply with a grain of salt...

The indoor malls that simply offered shopping and a food court are the ones dying off.I've seen some malls be demolished and replaced with high-density single family developments. 

There are some good food spots around here.

If it wasn't housing, food, or transportation, I didn't spend money on it. 

If these are even an average sized breed they can eat through a lot of food in a day/week/month.So the first thing is to get yourself financially stable.

I had a renter that rearranged all the furniture, left everything absolutely filthy, grease spilled all over the counters and oven, food spilled on the floors and table, trash left everywhere, etc.

Key: cleanliness, keeping food contained and not leaving pet food out, exclusion (blocking holes where rodents can enter), keeping vegetation away from the building.If it becomes a serious problem or infestation, then call in the pros.

That being said, we have an incomplete picture of your personal situation so please take this advice with a grain of salt.Good luck with your investing journey!

First of all @Diana Teng, have you ever gone to a restaurant and asked "is the food here worth buying?". 

When you are looking at estimated provided by the seller take them with a healthy grain of salt.
