The contract my realtor sent required a response by 5p of the day it was sent (not sure if this is standard but that is what he did)Ask yourself what you can do to improve the building, raise rents, putting in coin-op washer/dryer, basement unit, etc.

New kitchens, bathrooms, interior/exterior paint, coin op laundry added to basement, driveway replacement What was the outcome?

On the other side of the coin, everything looks easy on paper.

Will coin operated washers and dryers be a turn off?  

I also own all my coin op machines because I can't seem too find a company that doesn't steal and I could write a novel about how nasty their contracts all are.

The flip side of the coin is many people will still want to be in walkable areas...especially the younger demographics and up-and-coming professionals.

This is what propelled the high stock prices, bit coin, and real estate. 

i would always prefer coin op if given the choice since its a little extra income.

I like this adage (though you need to build on it perhaps): "The best time to invest in real estate is always twenty years ago" Heard it recently on The Real Estate Guys podcast, but they didn't coin the term.

@Brandon Turner Turner coined the term "House Hacking" to describe using your personal residence as an investment property.Read this: http://www.biggerpockets.com/real-estate-investing Listen to the Bigger Pockets Podcast with @Joshua Dorkin and Brandon turner.I don't have an Apple device so I stream the episodes on my Android phone using the Stitcher app.
