Mortgage Interest Deduction Married filing separately

[CGR_2020]

My spouse and I purchased our main home in 2015 and sold it in 2019. The mortgage balance < $500,000.

We then bought a (new) main home in 2019 and the mortgage balance > $500,000.

For the 2019 tax year, if I file as 'married filing separately' with itemized deductions, am I eligible to deduct 50% of the total mortgage interest paid in 2019?

I'm not clear on how to interpret the $375,000 limit if married filing separately.

Help/guidance appreciated!

If you are married filing separately, you may divide your mortgage interest and property taxes in any way that seems convenient to you.  However, the maximum indebtedness that qualifies for the mortgage interest deduction is $750,000 between the two of you.
