Too many times I have seen the most confounding electrical issues end up being due to some handy person's "repair", crossing the neutral over on a switched line when connecting to K&T, or worse.

Combine this with the once common practice of neutral side fusing and you can have defective, yet hot wires in your walls and ceiling.

I have found that the higher the class of property the more you will want to keep a neutral color because those tenants are very definitive in what they want.Also guys and gals, don't assume classes of tenants.

A P.H. neutral cleaner should be used with water as the weekly cleaner.

You can you passive losses to neutralize/eliminate passive income.

Title companies are supposed to be neutral.  

Student loan debt is neutral (most people can get tax breaks from the interest).  

@Jd Martin BP Landlords bandy the "professional tenant" dogma anytime a tenant holds you accountable for illegal activities.Your naked allegations don't hurt my feelings, and you can't and won't minimize or neutralize your liability.

I suggest getting a POBox or having it sent to another neutral location.

For oak floors (assuming solid hard wood and not laminate), I would let the Natures miracle soak into all the cracks so it seeps in where the pee is to neutralize those areas.
