I am house hacking, bought 2 single family primary homes in 9 months in Colorado, both with separate entrance basements and full kitchens down there (so essentially duplexes).

I am a 60 y/o man, I live in northern Colorado (Greeley) I need advice on how to proceed I currently have a primary home I also have a duplex (both mortgages), I want to improve cash flow and possibly purchase Investment properties, I can either refinance the duplex or take out a HELOC ($150,000 in equity), I can also roll over an IRA with approximately $300,000. 

May not be the most easy search, but depending on your market (we're in Denver and Colorado Springs), you might be able to find a home with 4br up and some kind of rental space downstairs.

I am living in Colorado Springs currently and have put in offers on close to 20 properties and have lost out the cash buyers every time.

We owned apartments in Colorado, Texas, Alabama and Arizona. 

I'll be working on a new development project here in Northern Colorado in the coming months.

For example, in Barcelona, that would be areas like Rubi or Terrassa. 

I rented an Airbnb in Colorado that had no AC, and no screens on the windows. 

I'm in Denver, Colorado and would appreciate any recommendations!!!

We work with a lot of Airbnb/STR investors in Colorado, and we definitely use AirDNA.
