Also not at all what OP is asking @Ryan Nolan This is only an issue if you're audited. 

You will want to use a real estate attorney who does commercial and multifamily, a good property manager as they will help with due diligence and lease audits etc. inspectors that do multifamily and surveyor.Check out https://joefairless.com/ and get his book and theres also tons of info on multifamily due diligence.

Well a friend was audited by the IRS BECAUSE OF WHAT THE CPA advised them to do.

You could do a Loan Audit which could entitle you to money damages and / or a new lower rate loan.

Some custodians are more prone to internal audit from the IRS than others.

Ask whatever company that does it if audit by Government is covered in price paid for the report etc.

They just send us an agreement stating that we must not raise rent after the energy audit.

These manufacturers go through two independent audits a year by MBMA for their engineering and manufacturing practices. 

Figure this:20% of the purchase price2% of total loan amountAnywhere from 1200 - 1500 hard closing costsFigure 800 for the appraisal and then the CDA (which is the in-house audit of the appraisal)Figure you'll make 3 - 6 debt payments while the work is being done. 

@Anthony WickIn our practice we don't execute anything based on "The IRS would never know" - they don't know a lot of things that they could only find if you were under audit.
