I think the building might not be ready for occupancy. Maybe there is some holdup from a municipality, investor, contractor, fire inspection that is the cause of the real holdup. They really should just return your money but please remember, the person you dealt with also must deal with a large bureaucracy. Maybe the company she works for thinks everything is OK and they just had a series of bad tenants. When dealing with the company you need to remember that person has no incentive in telling you no. At the end of the day they just want a paycheck and will do whatever their bosses tell them to do, right or wrong.

I believe CoreLogic was spun off from First American.

You may want to see if you are eligible to file a claim with your renter's insurance policy.

As for CoreLogic, you will want to use all the debtor's rights laws at your disposal. All those credit reporting laws apply to them, maybe small claims court would be a good avenue. Small claims courts will usually squash any unruly practices of a landlord.

The large rental management companies can be difficult to worth with as a tenant. At the same time its easier for tenants because they have more tools at their disposal especially in collecting minimal amounts of security deposits and timely repairs. They can be difficult when trying to break a lease, return deposits, or charging misc/extra fees. Sometimes there is no way around it. You need to go into the situation understanding you will lose money.

A good rule of thumb is more amenities => more fees => more problems!
