As far as what to look for in your purchase -- location, age, sq footage, lot size, future city infrastructure development or redevelopment, potential rental rates (near hospital to rent to medical staff), are you looking for cash flow are you looking for appreciation....etc ... etc... 

Do any of these groups use the Meet-up format, record session topics for those unable to travel to meeting sites, by using YouTube, Ustream or Skype like technology?

I will be super busy with work and travel while I am living in Denver, could I hire a property manager from the beginning for even when I'm living in the duplex?  

For a landlord who self manages, what happens when you are out of town for vacation or travel for work, or whatever? 

I am currently a project manager on a year-long Electronic Medical Record implementation at a local hospital.My not-so-long-term plan is to stop trading time for money, and I have therefore started learning about various ways to build up passive income.

I was traveling with a potential partner.

Very lucrative business in luxury vacation rentals. 43 million is the number of rental units in the United States alone $85 billion is the value of the vacation rental industry.92% of travelers want the option to book rentals online. 53% of travelers with income > than $125,000 prefer vacation homes to traditional hotels.

They wanted me to take positions that would include a lot more travel and prestige in the company but the $ per hour when all said and done is lower. 

If things beyond your control were going on, like medical problems, being late once is better understood.And, Welcome to BP!  

I am traveling right now but will PM you next week if that is ok.
