We had a similar situation with a second home we only used 4months a year. Between cost of capital and maintenance, it was $40k /year or $10k/month we used it. Sold it, invested the $$$, and we now rent. No stress!
Add up your annual maintenance, insurance,what you would get from a safe 10 year CD, and loss of equity per year. (Not to mention loss of sleep and stress you have). Use that to rent!
My recommendation based on listening, sell and rent!
(A rv, trailer, cabin, or motel) you have many stress free options!)
But in the end, do what you want, there is no wrong answer!
