Investors & landlords

OK, so the original loan was taken out in 2014 for right under $1m.  It was refied multiple times, recently in 2019 and 2020.  The outstanding balance has gone down.  So in 2014, my limit was up to $1m, but now that I refinanced in 2019 and 2020, am I still at the $1m limit or does the refinance cause me to be at the $750k limit?
