If you get traveling nurses, a lot of them work at night and sleep in the day. 

Assuming I had the experience, I would only buy a place with structural issues if I had 1) an experienced and trusted structural engineer telling me a clear, and verifiable explanation of the cause(s) of the problem and a viable and affordable solution, 2) trusted and experienced tradespeople who would be implementing the solution (carpenter, mason, etc.) confirming with me that they could fix the issue (with 90% or higher confidence that the issue could be resolved within budget), and 3) confirmation from city inspectors that the issue (and an inability to fix the issue) would not result in condemnation/revocation of occupancy permits. ...and even then, I'd only proceed if I had the cash reserves to ride out a major series of unexpected problems (e.g.; time overruns, budget overruns, unexpected revocation of occupancy permits from the city, etc.) 

While the market in Denver seems to be solid, and everything I find in my research seems to confirm that, I'm unsure of what the rental market is like and for what demographics (family, students, traveling nurses).

Hi all, I want to purchase a duplex to start my travel hacking journey.  

We travel for work and though it would be our “true” home, we wouldn’t be there often.

You could likely mirror the model in other markets that require transient workers such as traveling nurses or those working in the oil and construction fields. 

It just seems hard for these sites to get enough travelers using them, unless you have a property targeting a very niche tenant type that uses a specific website to find housing. 

The median sale price has risen to $650,000, an 11.11% increase that reflects the undeniable allure of Palm Beach living.What's more, 48.8% of these sales were paid in cash—a clear sign of strong buyer confidence and a testament to the value of these homes.

I live outside of Winnipeg, but would be willing to travel for meetups.
