The loan is non recourse, so I have no personal liability.  

I have quite a bit of debt that I am working on paying off (luckily it was loaned to me by a family member with no interest and no deadline).

You aren't touching anything on the Roaring Fork for almost any price, no matter the square footage.Location is king, because location equals desirability, and desirability translates into more rental demand, and in some cases, substantially more.  

Ease of working with owner = easier for you to cohost --- some owners micromanage and 2-3x the amount of work for you for no reason.

I have one lender that will go up to 85% but need 720 credit or better and 1.25 DSCR no rural areas

Well, this my opinion, if you like unpredictability, constant change and people/contractors with no regards to you or your property then "YES" flips and STRs are the way to go...LOL....I love it!!! 

Yes there are alternatives for both beige and 30 year loans for no US borrowers.

We built a single family home version of a 2 bed 1 bath with surface parking at cost with no profit all in with land for 175k in newark ohio, a suburb of columbus ohio. when we push that to 3 units and closer to the city for our build to rent model the numbers go way better. a 30k slab for a single family home is 30k, a 30k slab for a triplex is 10k a door. we designed a 2 bed 1 bath design at 668 sq ft and it's very good layout even I would live there, but I would never build anything that small again. there's no economies of scale. you need density and shared lines, resources, shared roof shared slab, shared windows, etc the cost goes way down.

I love being on the other side charging everything possible on a credit card but there’s no reason to accept them.
