Should I consider refinancing to help decrease my monthly payment (my current rate is 6.41%), should I cut my losses and sell the property (which I’m hesitant to do bc I don’t expect to househack again), or is there any other route I can take?

Many people think that they can or should be able to cut out a realtor or broker based on their opinion of the level of effort they've made OR the fact that they went around their backs and tried to negotiate directly. 

No need to waste my time constantly replying to, "Is this still available?"

Pros could be: Clean water + tub for each guest; on a well, so no water waste concern; can make it design-y + cute; can be used winter (hot water) + summer (cool water); goes better with forest location of the home than a traditional hot tub might; will hold same number of guests as hot tub would (2 people in each tub).In researching I have seen some people on Airbnb have these checked in amenities as 'hot tub', some 'private hot tub'.

Seems like I have my work cut out for me.  

If you put it out there asking for a 3-5 year lease with a small business or startup in your mind, but H&R Block or Supercuts comes along asking for a 10 year NNN (& it's corporate) and agrees to the rent amount you requested, there's no reason not to entertain that, you got better than what you were expecting (there's a reason NNN properties, or ones with a few NNN tenants sprinkled in that are national chains, often sell for lower cap rates), it's not like taxes or hair cuts are going obsolete any time soon. 

Unless you're on the beach, i'd avoid the flip flops and board shorts, but Also I think most people get defenisve or put off by suits when they are knocking on someones door, so Business Casual, collard shirt if that is something you'd wear or a Clean- Non Graphic T (unless you had your own made), clean cut dark denim jeans -- and some clean shoes. 

Saw a $40k price cut and made offer next day for full asking price and asked for $10k towards closing costs.

We could get a new car and do something fun with the money but that would just be wasting the equity we have built up...bad idea.  

First the underwriting process was painful and a huge waste of my time.
