How strong is the demand for mid-term in Denver?

I have a w-2 income and own three properties, all long term rentals, that I've had for a few years.

After reflecting on a strategy someone used to buy 15 short-term rentals off-market in just 12 months, I thought of an idea.

Or you can go a DSCR route (sometimes with no seasoning) but the terms suck.

While I will still lose money on it in the long run, I'm at least breaking even on it monthly and no longer have the headache of it. 

Most investors I know in this class of RE don't last long.

I'd sell because you are reaching the time when you lose the cap gains exemption and that $24K would take over 2 years of renting to get back.I had a condo that I owned for a long time and I sold it despite it being paid off and having long term tenants. 

I think that term, "clean BRRRR."

Is your tenant month to month or in a long term lease?  

I live in an area where rent appreciate quite a bit so it will always make money long term.
