I don't think any magistrate or court will make a landlord keep a relationship that presents harm to that person.

You can decide later to either become a better landlord in the future or do something else - no harm, no foul in either decision.

If as my rental portfolio grows, would it be a good idea to funnel more money into my workplace 401K and Roth IRA account?

Chances are I have bigger cajones than they do.At my previous company they established a "woman's legion" to meet monthly and promote woman specific issues in the workplace, and TBH it pissed me off.  

a situation where you cannot close is a disservice to a seller that is on market, and may harm them, all im saying is be carefull with the properties you are trying to wholesale, nothing against it, you just need a better strategy.  

I understand your concern with the pitbull breed, however if the dog is papered as certified as a service dog there should really be no risk of the dog harming anyone.

Having a background check does nothing to harm your criminal record or anything of the sorts, so why is he denying it? 

In other words I want no harm to come to the seller I just want the property!

And rightfully so.. so many wanna be investors with no money got into this stuff and really harmed many good americans.. its sad really. 

This, in my opinion does two things, 1, sets the standard and expectation that you are an amazing land lord, that has top notch service and has an elite property, and 2, it simultaneously sends the message that you demand the same from your tenants.Now obviously there's a risk you won't get the higher rent, but as long as your numbers work out at the lower market rents, theres no harm in trying to push them in my opinion.
