@Jessica StevensonI am a Realtor and investor here in Jacksonville and I would say concrete block homes are very sturdy and a great buy given age of home compared to the wood frames/stucco that are more prone to termites.

What kind of company can reinforce it or brace to make it safe and sturdy to walk on and under?  

I tried to reason with them but they responded disrespectfully and refused to clean up or keep their dogs on the leash, they don't let the landlord in the house, the don't pay rent for the past 12 months (or just about), they don't move out and keep lying to police and the property owner that they will move out but instead they just had another baby, brought in the 3rd dog, took the sign "for rent" down which landlord put up, and seems like have no intention to move out what so ever!!!

Countertops I always like granite because it is so sturdy, you can even put hot things on it.Once I got done with the first BRRRR I just tried to make that process repeatable in every way.

It might just be to sturdy up the floor.

Also install bright motion-sensor spotlights all around the property that trip whenever someone stands on the corner (protect by placing in hard to reach locations, covered with sturdy wire mesh guards).

The neighborhood was perfect for what I was trying to do (affordable for me and up + coming) and this house had a lot of great original character with sturdy bones.

You can require the animal is leashed or in a carrier on common areas, in particular elevators, stairways, and hallways, unless doing so prevents the animal from performing it's task.

Further, you can also place "reasonable" restrictions on the animals, including the requirement of a recent veterinarian report on the health and vaccine status, with annual updates; must be spayed or neutered unless contraindicated by veterinarian; must be in a carrier or on a leash (unless this prevents them performing their service or task) in common areas, especially elevators, stairways, and other areas where people would be in confined spaces; must clean up after the animal properly in common areas; offensive odors must not emanate from the residence; aggressive or nuisance behavior (such as extended periods of barking NOT related to the service or task they provide) can be prohibited, and potentially grounds for removing the animal and/or the resident; animal must have a chip or collar with owner's identifying/contact information; must have appropriate city/county license if required locally; and photos of the animal for your records.A thorough and clear policy will deter many of those that are less than sincere from applying when they are made aware of the policy details early in the process...like at the viewing, and mention of the policy in ads.
