Renting out 2 beds in a 3/1.5 - getting from 25% to 0% mortgage?

[Kenneth Westervelt]

Bought a house last month for 285k in the suburbs of Denver. Looking at various rooms for rent in the area, it looks as if fair market rent this year will lower my cost down to roughly 25% of the mortgage.  In a perfect world, getting down to 0% or even -25% would be grand but I don't see that happening until at least 5 years down the road.  It will take probably at least that long for inflation and demand to shift to that point.

What strategies have you used to accelerate the process towards getting tenants to pay the entire mortgage? Is such a thing even feasible?
