Over-improved a house I thought I was going to live in long term

Long story short, I thought I was going to live in Grand Rapids long term so I bought a house for $450k and after some surprises and some impulsiveness I ended up spending $370k on renovations. 

Due to work and personal circumstances, I would like to leave and move to Chicago within the year.

Even though it truly is a beautiful and very unique modern home after the renovations, a real estate agent I’ve worked with before told me the house wouldn’t resell right now for more than $650k (even though the house is like 300 yards away from neighboring East Grand Rapids where homes like mine go for 30% more just because they are in EGR).

So I have an unrealized loss of $170k if I try and sell now which really isn’t an option. Based on appreciation trends in Grand Rapids, the house won’t appreciate to break even in like 6-8 years. I estimate I could rent it for $3,500/month which isn’t amazing but feels like the only option now.

I wanted to check with the community to see if this has happened to anyone else and maybe get some advice as I’m feeling really stupid. I very much appreciate everyone’s time and thank you very much in advance for.

Additional context: I paid for the house and renovations by getting a bridge loan from my parents. I’m planning on selling my Nashville condo next year and expect to be able to pay them back around 60% and pay the rest by taking out a mortgage. They’re not pressuring me to pay back until the Nashville condo is sold.
