My worries lie here; as you can see the property is out dated and ugly on the inside.

The complexity of turning a shell of a building, with what looks to be outdated mechanical systems and structural elements that most likely needs updating, as well as any city permit/planning elements are part of the equation that you have to consider if this is worth the risk.I know I will get flak from members of this forum.

I was even able to resell the outdated ones that came with the house and ended up nearly breaking even.

Some homeowners even rely on outdated autovaluations like Zillow's Zestimates for home values.

Maybe my version is outdated or maybe that just doesn't work here.While working on my business plan, I'm trying to create something basic that will allow me to have a template to follow.

The off white may be a very light member of the greige camp, but the other two I would call bone and...well, beige and not greige and not tan and not almond (note, I am color challenged but beige can be yellow or pink and while neutral, completely outdated due to undertone...my first and last quart of greige, used as asubtle accent wall, had a disappointing purple undertone.)  

If it produces more energy than it consumes then the building is Net positive - though Net Zero is too frequently used as a blanket term to cover both these cases.Ironically, Net Zero does not automatically imply higher energy efficiency - there are several examples of commercial buildings with large expanses of flat roofs (i.e. warehouse) which are net positive, despite the building itself being horribly inefficient.Building standards in North America are woefully outdated on matters of energy efficiency.  

I have used to search function and everything I have seen has either been outdated, blog topics or other new investors asking questions.

The home is in very good condition however ever it is very outdated.
