Some conduit outside and both of the 800 sqft units got a new panel, 5 in wall heaters, 2 fans, basic fixtures (not recessed lighting) and outlets to code.

I am currently investing in Cape May and Atlantic county.There are tons of ways to get involved and surround yourself with other investors that are doing it and doing it well.Kurt Kwart is an amazing resource that hosts investor panels as well.

Turns out the panel was old and not wired properly.

The finishing panels that go on the ends of the on-the-shelf are horribly cheap, the buildup is too thin and the self-adhesive is a joke.Considering the price difference, I won't go the off-the-shelf again unless we're talking some tiny section of counter that needs to be added, an island, etc.

bottom panel is a different shade of brown so I have to repaint the entire door unfortunately.    

@Michael Dang I used to work with MBCI in Houston on metal roof and panels for my projects, but it's been a while.

While most Net Zero buildings are energy efficient, perhaps even highly so in comparison to minimum building code requirements, there is nothing requiring them to anywhere new the efficiency level of a Passivhaus   .... this is why you will see odd things like warehouses with large rooftop solar installations being able to claim Net Zero.On the other hand, Passivhaus sets three metrics which a building must meet to be certified as Passivhaus compliant:  The building must have a heating and cooling demand of not more than 15 kWh/m2 (4,755 BTU/sq ft; 5.017 MJ/sq ft) per year  and a peak heat load of 10 W/m2.Total primary energy consumption (energy for heating, hot water and electricity) must not be more than 120 kWh/m2 (38,040 BTU/sq ft; 40.13 MJ/sq ft) per yearThe building must not leak more air than 0.6 times the house volume per hour (n50 ≤ 0.6 / hour) at 50 Pa (0.0073 psi) as tested by a blower door.Ironically, the research and pilot projects which fuelled what eventually became the Passivhaus standard was carried out in Saskatchewan as a National Research Council (NRC) project in the 1970s (the house is still in use today) and a similar project (Minnesota?)

Here is a part of the letter, I sent to the seller:The home inspection was completed on September 29th (please see attached) and the following issues were pointed out: 1.The wooden floor frame in the middle unit is deteriorating due to either prior water leak in the bathroom or due to moisture infiltration through the walls and foundation.2.There is evidence of significant settlement under the middle unit bathroom and north closet.3.The settlement of the floor and walls has also resulted in settlement of the roof frame above this area, ceiling shows cracks.4.There is an obvious depression on the roof – water is ponding on the roof above the middle unit, which adds excessive weight on the roof and potential for leaks.5.Asbestos containing material has been found.6.The current bedroom heat installations in the north and south units pose a safety hazard from carbon monoxide, fire and oxygen depletion.7.An electrician performing upgrades did not use ‘arc fault breakers’ in the north and south unit breaker panels, which is required by the national electrical code.8.Upgrades to the electrical system, promised by a real estate agent, have not been completed yet.

@GrantAndersonI recently did a lot of research into these "green" programs for solar, energy efficiency windows & doors, tankless water heaters, etc.  

Since all the mechanicals are in the basement it goes without saying that the furnace, water heater, and electrical panel will all need to be replaced.
