Electrical has aluminum wiring

[Bienes Raices]

I had my inspection yesterday and the inspector pointed out that aluminum wiring could be an issue with the insurance company. He suggested seeing if they would accept adding arc-fault protectors in order to write the policy. Since the house was built almost 40 years ago, there is no hiding it from the insurance company because they'll require a 4 point inspection. (besides, I wouldn't want something hazardous anyway with tenants living there).

I'm going to call my ins. agent Monday morning when they open to find out what the deal is, but I was wondering if anyone else has been through this, and what the outcome was--what changes did you have to make, did they want you to rewire the whole house, do you pay a higher insurance premium, etc. Thanks!
