I'd probably not operate the property as an LTR because with such little down (5%) at today's rates, it would be negatively cash flowing.For the investors who invest in Littleton and have a furnished rental, can you speak on what the MTR and STR demand is like?

Right, again.Always offer cash, worry about the leverage aspect later.

I have already analyzed my deal in the Rental property calculator, its coming out a negative COC ROI.

Speaking as both an investor and realtor based in FtL, these small MF are very difficult to get into at the moment due to excessively high pricing leading to negative cashflow if you plan to finance them. 

I have long term rentals but for many years I was only slightly cash flow positive and larger negative events put be back to break even and even a few negative years.Here is the upside and how I changed my mindset.

Just remember: most negative reviews are written by problematic tenants.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.

I am also researching lot of these aspect.

Being curious and accepting that you don't know everything is one of the most important and freeing aspects of investing. 

We thought keeping the old townhouse because it can generate positive cashflow or maybe a little negative cashflow if something needs to be fixed.
