Some common ones that come to mind in addition to a hot tub are a cedar sauna (gotta lean into that Minnesota sauna culture - check out Cedar and Stone out of Duluth for some really cool sauna ideas), snow shoes or cross country skis, or even just a nice outdoor firepit area with tons of firewood (you could also include complementary s'mores supplies for every reservation).  

Also depends on if you will ever want/need a roommate, one advantage of a 2bd is obviously if you are ever in pinch you can rent the 2nd bd, but if your pretty confident that’s not something you’ll do, I’d lean newer 1bd, not to mention that’s where the best deals are right now.

I would generally lean towards selling it and cashing out to reinvest in a better property.

I'm a fan of running lean, but you're one bad month away from borrowing for necessities.

If you want appreciation, identify markets with expanding industries, positive growth trends, and bright economic forecasts.Columbus, Ohio is a great market to consider if you're leaning towards that appreciation!

I wouldn't want to take the capital gains tax hit so personally I would lean towards a 1031 with a lower maintenance property. 

I'm leaning towards selling before I need to dump a bunch of money into the property, but I'm second guessing myself because I'm sitting at a 3.25% interest rate and cash flowing close to $1,000/month before reserves. 

We can always hedge our position in stock/stock index by placing order derivatives that would limit our downside.I am quite mastering this aspect and this is what makes me more convenience for index investing (not stock but index).In syndication we're literally on the mercy of GP (which hopefully a good guy) and the actual asset itself (hopefully they purchase the right asset without so many issues).

I would lean towards house hacking your first rental.

If the rents are low and it's difficult to fill, you'd be better off selling the property.The value of the property will continue to go up over time, so I'd lean towards holding, but you'll want to look at the market you are in before committing to a long-term cash-out refinance.
