I am in the process of purchasing a mixed use commercial and residential building.

If you delead, and maintain the standard, you will be in the clear.Here's the law (emphasis added by me):460.100: Duty of Owner(s) of Residential Premises (B) Whenever any residential premises containing dangerous levels of lead in paint, plaster or other accessible structural material undergoes a change of ownership and as a result a child younger than six years old will become or will continue to be a resident therein, the new owner shall have 90 days after becoming the owner to obtain a Letter of Full Compliance or a Letter of Interim Control, except that if a child younger than six years old who is lead poisoned resides therein, the owner shall not be eligible for interim control, unless the Director grants a waiver pursuant to 105 CMR 460.100(A)(3).

Some areas allow residential to be used as office some do not. 

You can get some significant discount on rent and if you’re looking for commercial there are deals to be made but not residential..

In general, I would research and/or ask him or her the following:- Is the attorney a 'generalist', or do they focus on real estate, business, and realty business matters?

I do know that COVID has made people place a higher premium on where they live and on ownership, that lending rates are excellent and that banks are hungry for residential and MF opportunities because they are being really conservative with retail, office and hospitality/ground-up developments.

As a result, when I sell to a resident, I usually offer them a good discount off of retail price.
