First it’s an unrealistic story in the modern economy and serves as an analogy for the workaholic and fatal pursuit of growth for the sake of growth.

I agree black looks more modern 

I as the owner of the house had two choices: a) rip up all the floors and replace the bad system with a new one or B), get the most massive, modern, A/C heating system I could have never afforded.

Look for markets with good economic/demographic trends and diverse, modern economies and industries.

I use a local branch of Farmers here in Colorado to insure my business with a general and professional liability policy but I use American Modern Insurance for the property I own to replace my homeowners policy. 

But in the 5,000 history of modern humanity housing has been there. 

They can provide a modern and fresh look to your units, attracting potential tenants.Fresh coat of paint: Hiring a painter to give the units a fresh coat of paint is an excellent idea.

What I typically look for is something with good bones - structure is sturdy, roof is in good condition with many years remaining life, there are modernized plumbing and electrical systems.

This would be a good option if you're looking to buy a place to do value add via major renovations on and really modernize. 

A small unit upstairs in a modern build would not be an issue bbut most two families are not set up that way.
