So if it is less than that, I try to outsource these tasks to someone (including realtors) so I can work on other tasks. 

I do understand that YMMV, that only a lawyer can answer these, but this could also be a jumping off point for anybody else interested in this topic as the rest of the Internet is pretty lacking.

I have the opportunity to make my units lead-free and one of the tasks on my list is to install radiator covers.

In an effort to focus my energy on the right tasks, I am hiring a VA to take on the more medial tasks that have been eating at my time.

Most MLS listings are also available on the Internet at sites such as www.realtor.com, thus allowing home buyers to research what's for sale on their own.

let's call these low cost marketing ideas...since you have to invest something...I.e. paying for your phone/internet.1. 

I don't use the Microsoft Internet Browser. 

Forget about Yelp, Angie’s List or Task Rabbit, I’ve only been able to find competent contractors by word of mouth.

I asked them why they never respond to my calls and emails about the section 8 people dealing drugs out of the house across the street, with dozens of people living there (every neighbor hates them) but they have time to troll the internet looking for landlords to sign up....Pathetic joke, our government...

Scorps have some odd other rules as well involving health insurance, vehicle expense ect so talk to a CPA or EA or someone who's not on the internet first as well.
