Insurance will cover damage to their possessions, but you are talking about inability to use the apartment, not their possessions.Lack of water/sewer service means the apartment is uninhabitable.

@Carl W., first off you never state who should be paying for the damage? 

Mind you; there are no physical damage to the garage door itself.

Their choices are: 1) Take you to court, which if they didn't follow their own management contract, won't work out for them.2) Try to put a lien on your property, which you could sue them for damages and attorney fees.They sound very incompetent if they did work without your approval AND without upfront funds from you.

The damage by the outgoing tenant was not that extensive to warrant all the upgrades.

I am looking at a house that has suffered a lot of damage post foreclosure.  

This also allows for property owners to more easily write-off assets that get damaged/destroyed as the value of these assets is determined as part of the study.

Plus, even in that extreme circumstance, by fixing things timely it prevents additional damage and completes repairs BEFORE the unit is vacant making it faster to be rent ready for the next tenant. 7.

Also, I am scared a tenant cant damage the home and leave it unappealing for me to move into....and lasty, taxes or insurance can grow out of proportion leaving me not wanting to move their in the future. 

If the patio or walkway was damaged (ie large cracks or uneven), then you should fix it as it poses a trip hazard.
