Yes, the Fort Collins market is very hot right now and our Cash on Cash Return On Investment is not the best out there, but you can still find deals where the overall return with cash flow, a reasonable 3% appreciation (not the crazy 8-10% per year we've been seeing), debt paydown and tax benefits should make you at least slightly cash flow positive with an overall return (not cash on cash) pushing 25%.
My two favorite strategies in Northern Colorado right now based partially on availability and ROI are Nomad and Lease Options.
Here's a chart showing some properties that are available and about 6 months of previous sales estimating cash on cash return on investment (just the cash flow part of the return) in Fort Collins for 3 bedroom homes. There are some data points in the 0-5% cash on cash return range with a couple outliers (that might be funky), but a large mass of the data is just not good cash flowing deals.
Hope that helps.
