I would paint metal but am skeptical about longevity of paint on vinyl.

They can also help create policies and procedures for both employees and employers that are crucial to the longevity of the business.

I get Consumer Reports, but I've bought some stinker products using their advice - their problem is estimating longevity. 

Having a license gives you more tools on your tool belt and as long you continue learning as an agent and as an investor you will likely have more longevity in the business.

@Kyl May brick is definitely better for resale and for longevity, but I doubt it will make sense once you get the bids back.

In the cities where my houses are located, we have a large enough population base, diversity of employment and brick/block houses for longevity of investing. 

I'm due to replace my triplex roof, and I received quotes around $9k for shingles, but it was only $10-$12k for metal; so I'm leaning towards metal for longevity unless you guys tell me otherwise.

Longevity is nice but remember styles change.

The key to longevity is proper prep work and using the right kind of paint.
