Right now, there are a lot of investors buying these properties with just over neutral cash flow in year one.

The Color of Law: A Forgotten History of How Our Government Segregated America by Richard Rothstein is a great book about how the housing market is not neutral. 

I would only do that if you are at least cash flow neutral while living basically free in one side. 

In this example, the Realtor can offer both of you to become a dual agent (more 'neutral') and once you two work out the price, the agent can be assists both in coordinating the transaction. 

It could take 5 years to where property would be cash neutral if a rental.  

That is, if a policy is facially neutral but causes a significant disparate (unequal; different) impact on one of the protected classes, then a person in that class has a cause of action.What happened next was issuance of the Office of the General Counsel Guidance on Application of Fair Housing Act Standards to the Use of Criminal Records by Providers of Housing and Real Estate-Related Transactions (HUD, April 4, 2016).

Eventually something will go wrong with the pump, the acid neutralizer, or the well itself.- when I asked about getting city water they told me it would be at least $2000 to get hooked up, plus I would have to officially close and seal the well for thousands more (instead of being able to keep both for zombie apocalypse).

But a legit bathroom that is permitted and has neutral finishings will always increase value.

Even then, cat piss was worse to deal with and the above + neutralizer on the concrete worked for it.

If you do everything else, you may be able to neutralize the duct odors until they burn off.
