Focus energy on networking with their foreclosure or collections departments.

At your age and with your energy, your destined for greatness, keep going don't stop.

Honestly if it has drug activity and shootings near by you will have a tough time keeping it rented.You can make all the improvements you want to the inside but if the neighborhood stinks it won't ever rent for more in the future.If you wouldn't have your wife pick up the rent checks because of the area then I would pass.

For example, if I want to move from NYC to Denver, what is the fastest and most efficient way to learn the neighborhoods of Denver and surrounding areas?

It just needs some improving to make it look at little more modern.  

Since I only depreciated part of the total repair cost ($5500+$3000=$8500) from 2012 to 2014 what happens to the remaining amount that I did not get a chance to utilize yet since I sold the property before I fully depreciated the improvements?  

Energy prices went in the toilet and on and on.

I know I totally butchered the first few leads just getting used to the calls and questions but I have gotten quite a bit more efficient and confident in taking calls and talking to people about their property.

Is anyone familiar with an efficient way to determine which properties on the market for sale have no existing mortgages?  

Nor do I care to waste energy trying to figure it out.
