Then build firewalls between properties and businesses.

Some do well with it, others need to set up fire walls so they can focus and not be forced multitask.

I even dumped a few bags in the fire wall space between units in the attic.

“The way my realtor and I typically work is he knows I just want to hear numbers.”Do you believe this sets up some sort of firewall between you and you borrowers?

When they build them they need to make sure they build fire walls between units that go all the way to the roof.

Rehabbed and flipped it.Took it down to the studs, and then called in the Building Dept Inspector, and told him our plans.He agreed with everything that we wanted to do.As the work progressed, we had him come over to take a look, and he said, everything that we had done, was exactly the way he would have done it.We had to build a fire wall in the basement, because the garage was part of the basement.We thought that we had to put in a solid metal door, and he told us, that a solid wood door is legal.

There is also a brick parapet running through the middle that acts as a firewall between the four units (it is a quadplex).

Get a new PM who will act as a true firewall and also implement your goals and strategies.

For example: there can be no plastic pipe in plumbing, the walls between units must meet certain specifics to be a firewall, if it is forced air each unit will need its own furnace as units cannot share a return air duct, etc.  

If you get a lot of these or have high net worth you might want to think about a intermediary LLC to act as another firewall.
