Electrical Problems in an older building

[Ann Tavsanli]

I bought a multifamily building and have run into a capital expense that was not on my radar and it was not on the inspection report. I had planned for things like the roof and painting, etc 

Apparently the electrical system on this property is under powered. Each unit has a 30 amp system which is not enough to handle AC units, appliances and today's resident usage. During the summer we are frequently dealing with popped circuit breakers and outlets going out, which is the result of an overdrawn system.

An electrician was called out and he wants to demo and install a completely new electrical system (2) new 20 amp gfi circuits in the kitchens, and (1) new 20 amp. gfi circuit in the bathrooms, of each unit and gave a proposal.

Have any of you had a similar experience. Did you install a new electrical system or do you know of another way to resolve this kind of problem? Looking for advice as this is very expensive.
