Should I be looking for a tax attorney, a real estate attorney, or a trust/estate attorney?

The client retained the services of a well known attorney who has a great record of winning these types of cases. 

Get advice from a landlord attorney.  

SEO, cold calling, networking, hitting up probate attorneys, hanging outside the funeral parlor..... ok maybe not that one but point is the strategies are all but endless AND THEY ALL REQUIRE WORK. 

Majority of mold complaints are tenants panicking and/or trying to get free rent out of their landlord.If they do get an attorney involved, their attorney will send you a written notice, which will lay out the issues and often tell you to give the letter to your insurance company.Don't bother with this, but you can discuss with your agent.When you or your PMC (or both) receive a legal notice of a case started, that's when you want to get your insurance company involved.Recommend you keep a record of all your communications with your PMC about this issue.

☝️Don't be cringy...That's literally what an attorney said on a recent REI Zoom.

Next is to start building a strong network of local contractors, property managers, agents, lenders, and attorneys—they’re key to keeping things moving smoothly.

I'm not an attorney, but here are some things to think about.

If we put what her husband did to the side (I would recommend that your friend consult an attorney for that) and assuming "made the HELOC go away" means to pay it off, then most certainly this makes sense. 

Always keep personal and business accounts separate, document all transactions, and consult a CPA or attorney to ensure compliance and maintain liability protection.This post does not create a CPA-Client relationship.
