<human>: Can you provide a brief rundown of the text in within 3 sentences?

Let me start out by saying that the house seemed like a steal for rent in Los Angeles.

The Landlord is an old lady who renovated the house to get it back into shape to be rented out. We looked through the place a few times while it was the process of renovation and before moving in. Each time we were there, we only saw the interior for a short amount of time. The landlord kept acting like she had somewhere pressing to be and any problems we pointed out was met with an assurance that it was going to be fixed.

Now we realize that she pretty much just sloppily threw a layer of paint up and installed the cheapest carpeting she could find. After we moved in, we were able to truly see the extent of damage hidden inside the house and we don't know if it's actually going to be habitable.

The gas company couldn't turn the gas on because of a leak and the water heater is a fire and carbon monoxide hazard with no proper ventilation.

The new locks installed on the doors were done above the old ones. The front door now has two door knobs and a hole where the original used to be. The back door only has one functioning deadbolt and a locking door knob meant for the interior. (No key hole. The type you can unlock with a paper clip)

Oh and the foundation looks riddled with wood rot.
<bot>: How do we ensure that the Landlord fixes critical issues as soon as possible? Should we hire a house inspector since we truly don't know the extent of problems in the house? What recourse do we have here?
