When to cash-out refi?

[Ryan H.]

In July of 2022, I purchased a SFH and obtained a 30-year fixed @ 6.75%. The property appraised for $30k more than the purchase price before improvements, and I then added a new roof, new AC, new carpet and flooring upstairs, a washer and dryer, and a bunch of general repairs. I'd like to pull cash out at some point to continue investing, and would also like a lower interest rate.

When would be an appropriate time to consider a cash-out refi?
