We may work together to sort this out.

What sort of things should i be looking at, or focus on to make it appealing and enticing to renters?

Thats why I am asking hereWell, that usually indicates some sort of financial hanky-panky......not accusing your significant other of anything, but just saying........I mean, what other reason could there be for refusing to pay a tax guy a couple hundred bucks....?

You sift and sort the ones that are not an optimal fit right away to leave the precious time for those who are the ideal clients and give them high service.The ones mentioned brokers/agents are a dime a dozen might be doing business on cost only and who is the cheapest.

Someone not paying rent is not a covered Peril.If coverage for this exists, it would be in the insurance bonding market in some sort of form of a Performance Bond. 

I started because I wanted to build some sort of lasting empire, I chose Denver because I live here (that was my first big mistake), and I started with Mid-term Rentals but I really enjoy short term.

Just curious - what sort of rent can you get per room in a house there?

It's an opportunity to borrow money, sort of like a credit card.

Would that be possible to have a try before you buy sort of thing for the exclusive partnership? 

Real estate investing is definitely a solid way to reap the benefit of cash flow from an asset - I would recommend starting with a SFH and then working your way up to multifamily once you are confident and have a better idea of what you are doing - you could look into doing a HELOC or some other sort of refinance on your current home if you need proceeds for a down payment - I would highly recommend building a relationship with a lender who can help you with funds for the purchase of a rental.
