Mortgage Payment Splitting: Principal, Interest, Escrow, and Schedule E Reporting

Every rental property mortgage payment contains four components: principal, interest, tax escrow, and insurance escrow. The IRS cares about the split because only the interest portion is deductible on Schedule E. Principal is not an expense, it is equity paydown. Tax and insurance escrow are deductible, but on different lines than interest.

Most landlords either guess at the split (wrong), deduct the full PITI payment as interest (very wrong), or spend 20 minutes per property per month looking up the amortization schedule on their servicer's portal and manually calculating each component. Multiply that by 10 properties and you are spending hours on data entry that should be automatic.

These posts cover how mortgage payment splitting works, why it matters for accurate Schedule E reporting, how to read your amortization schedule, what happens when escrow amounts change mid-year, and how to track the split across a multi-property portfolio without logging into five different servicer portals every month.
