They figure this would pay for the increased number of code inspectors to set a regimen of inspections every 2-3 yrs.

You can also hire a home inspector or lender construction inspector to do the same thing for you. 

Also the inspectors sometimes make off the wall request that you need to address in order to get clear Certificate of Occupancy for your end buyer.    

And in my opinion the property should have been marketed as a fixer upper because it is selling at retail and needs major repair, as the inspector recommended the roof gets replaced. 

After ten days they finally sent an inspector out.  

You'll need a realtor, home inspector, lender, contractor, leasing company, and property manager at minimum.

The existing work is done correctly, but in Chicago the inspectors want everything to abide by overly strict Chicago code to the letter.

I had a degreed civil engineer inspector that was recommended to me.

The inspector, 2nd contractor, and 3rd contractor all advised me that the home does have a foundation issue because there were multiple visible branching of cracking through the bricks and sheetrock totaling the repairs value to ~$35k.

I'd be happy to refer a client to a financial adviser in the same way I'm willing to refer them to an insurance agent, mortgage broker, inspector, contractor, et al.
