I'd vote against refinancing into a higher rates unless it truly makes sense. 

If I could give it to zero ratings I would.

I get about an 85% hit rate.

You sit and you wait....With new construction waiting isn't as bad a renovation because your holding cost is around a 7% rate, where as a renovation you are probably on a hard money loan at 12-15%. 

Our rate is a 3.5% fixed with 27 years remaining.

I am patiently waiting for prices to drop for no other reason than the market stagnation due to high interest rates.

Currently at a 50%+ savings rate, making it work.

Instead, rates are increasing.   

We are currently trying to book high-season months 2-4 weeks prior to check-in because we see the highest rates this way.

Make sure to thoroughly research the real estate market in both states, taking into account things like property prices, rental demands, vacancy rates, possible appreciation, and income potential.
