Building an ADU is a nice way to add value but you won't get that funded by a lender. 

Just keep in mind that there are further steps you'll want to keep to minimize the possibility that your entity is ignored for this kind of personal liability (say, if you were the person who didn't properly clear snow, or if your finances and the LLC's are comingled).And I agree with @Chris Seveney, insurance may provide adequate protection based on what's available to you.

That will depend on the taxpayer's personal situation.

My wife and I plan to purchase a few properties ourselves, but with the lead generation strategies I’ll be implementing, I expect to come across more deals than we can personally handle.That’s where you come in!

Above just the assumption that it'd be far more of a corporate environment, I just don't think that would happen at a larger shop, at least not for quite awhile, and I do think I would generally be more at home with a smaller office of people (smaller being relative to multi-national, or coast-to-coast, I suppose).Personally speaking, do you find that you're in that type of environment with a boutique brokerage?

An ignorant person lacks knowledge or awareness.

Keep in mind that DSCR loans are how most investors have scaled. whether its residential DSCR or commercial DSCR at 5+ units. personally, i like them better. few reasons why:1. seasoning period is only like 10-30 days vs 60days going conventional2. seller max contributions DSCR is 3-6% where conventional its only 2% max3.

I would be very interested in the person’s contact information that does Pad split in this geographical area. :)

It's best to invest in a company/fund that does this for you.
