I would recommend getting a pre-approval from a mortgage Lender and from a local credit union to see all your options. 

DSCR is a better option if you want to move quickly once you get your FHA back because if you refinance into conventional with primary residence pricing, you will need to live there for 6 months after.I would make sure that you get a side-by-side comparison between rates, fees, APR, closing costs, etc. to determine which product is best for you.

Ski/snowboard in te winter months or enjoy the river/ hiking in the summer months.

I am looking into taking a pre-licensing course online in pursuit of the North Carolina Provisional brokerage license.

Had a wholesaler reach out to me about a pre-foreclosure that goes to auction on the 10th.

How do I go about getting a pre approval low interest rate loan?  

I've been putting off STR due to the ease of the LTR model but would I be better off investing the money in a STR property through winter (ski area) to at least pay for itself plus gain the equity then re-evaluate in spring?

I have a duplex in which we lived for over two years within the past five years (Dec 2016-Apr 2019) and also a primary residence in which we have lived for over two of the past five years (Apr 2019-present).If I’m reading the capital gains tax rules correctly, only my current primary residence can be exempt.  

My PR has a 2.5 APR.

The reason I ask is if it's a pure investment -- and being close to Denver for personal reasons isn't important -- you could also consider some of the mountain areas in the front range that aren't ski areas.
