A new house was built and sold across the street for over 800k.The whole street is new expensive houses and my house is the ugly duckling. 

The building is located right on a main street in a small town 30 minutes north of Green Bay.

Quote from @Dan Hinz: My business partner and I are looking at buying a property in Akron, OH, but we aren't intimately familiar with the city yet (we both live in Florida).Other than virtually driving around on Google Maps Street View, does anyone have any suggestions on how to analyze specific areas and neighborhoods?

What's considered smart business in RE is called insider trading on Wall Street.

One street may be decent, while a block or two away can be very unsafe. 

On Wall Street, almost uniformly those with a "high" dividend such as most anything 7%+ would be considered, of stock price DECLINING over time, not appreciating.

.+  Across the street properties start at $400k.+  I am all in on my waterfront for around 600k and bring in about 50k income. 

An ADU is an Accessory Dwelling Unit -- specifically, a garage or other structure converted into a living space like a studio apartment.Houses can have one ADU and small multifamily property can have two ADUs (and more under certain circumstances).Here's an example deal, one I was exploring with a client recently:https://www.redfin.com/CA/Los-Angeles/624-N-Evergreen-Ave-90...This fourplex has two large garages, each of which can be converted into a studio apartment collecting $1600/month in rent (with plenty of off-street parking still available for tenants).

I've seen beautiful homes on google street view, only to drive it and see the house gone and fresh dirt. 

So if you are buying a house on a street where nobody lives and has been vacant for years it's going to be challenging to find someone who actually wants to live there.
