Actually the ones with a discharged bankruptcy are some of the best because they have almost zero debt and can more easily pay the rent.The ones you have to watch out for are the ones carrying a ton of debt barely treading water.One little thing goes wrong and and it will all fall like a ton of bricks.Now if they habitually filed bankruptcy that might say something.You can look up bankruptcies and history of people online using the national system.If they have little to no money for a deposit ,bad credit,and want to move in on the weekend and say they love the place without asking questions..........RUN

A UV vs corona discharge will definitely do the trick if you can find one to rent.

As the person in charge of the estate you will need to satisfy and discharge the debts by either negotiating with the creditors (both secured and unsecured), liquidating (selling) estate assets, borrowing or using your own resources (savings, selling assets or borrowing on your own property).As the sole bene (another hat you wear) you are destined to own whatever remains.

The sump pump discharge looked fine and was dumping about 10ft off the walls. 

An earlier post mentioned the fine for discharging refrigerant into the atmosphere; although you might not get caught, see link for some examples of enforcement:https://www.epa.gov/ozone-layer-protection/enforce...And intimate knowledge of electronics is not the same as intimate knowledge of the NEC - if you said you had the latter, doing your own wiring and breaker panel work would certainly make more sense.Where I am located, the electric power company will not turn power on for a building that had service disconnected for some long time without first having an independent third party electrical inspector sending paperwork to the electric company stating that the service line and existing meter and panel is safe - so this might be something you would want to become familiar with in case your electric company has a similar requirement.

, and then wreaking havoc on the Public Record by recording the wrong discharges or partial releases over the wrong properties.... 

Dehumidifier is good if you have a place for the water to automatically discharge. 

@Shez B.If the OP refinances the home after he has reached >20% equity, then he could discharge the high-ration mortgage and place a standard mortgage in its place.

Next need a list by tenant of any chemicals and how they are discharged by air, water, etc and their containment.  

If so, you can provide a payoff letter and let them know that you would OR pay the escrow company to record discharge of mortgage; after payoff has been received.Generally, it is not a good idea to send the orginal; that is a big risk.
