That's partially true, but it depends on the bank.

I would hate to lose the lower rate loan and not be thrilled to give up the prop 13 savings.

Nashville sucks for house hacking as most of these properties can barley cashflow anything above a positive cap rate.

As a result, it seems the value is really just very long-term and if we sold it in the future, any repairs and taxes would cancel out much of the gains (depending, of course, on the pace of appreciation -- who knows what that'll be?). 

Seems like it is a market which is only for STR, and resale is also mostly dependent on that.However, the appreciation for the last 10 years has been significant.

My questions are:a) Is it worth paying that 15 year note off earlier with that interest rate?

My current mortgage payment is around 2700 with interest rate of 7.15

This would depend on local municipality requirements.

I know some experts on here expect a correction at some point, but with rental rates being near all-time highs, I think this makes the midwest extremely viable right now.Also, if you want to thing long, long term, check out some articles about climate refugee cities in the midwest and how they think they will be major factors as climate change gets worse and people start to leave areas negatively affected by climate change for a more stable climate.Truth!!

Depends on if crawlspace or slab...depends on if you can find a dependable plumber you trust.
