Loan events

A loan is a history, not four numbers

Most tools store a mortgage as an amount, a rate, a term and a start date. Refinance, and you either overwrite it — losing every year of interest you actually paid — or you create a second asset and break the history in half. Neither is what happened.

An asset's loan history: a refinance and a recast on one timeline, with today's balance amortized from them
What it does

Refinance

A new balance, rate and term from a given date. Everything before it keeps the old schedule; everything after runs on the new one.

Recast

A lump sum against principal that re-amortizes the payment without changing the rate or the maturity.

Rate modification

A rate change on the same loan — an ARM adjusting, or a lender agreeing to something different.

A running balance

Today's balance is amortized from the original loan and every event since. It is not a number you keep up to date by hand.

How it works

Record the event

Date, balance, rate, term and a note, on the asset's loan history.

The schedule reforecasts

From that date forward, on the new terms. The years before it are untouched.

The metrics follow

DSCR, LTV and interest-rate risk all read the reforecast schedule, so they describe the loan you have now.

Questions
What happens when I refinance?
You record the refinance as an event on the loan, with its date, balance, rate and term. The amortization schedule reforecasts from that point rather than being overwritten, so the years before the refinance still show the interest you actually paid. Recasts and rate modifications work the same way.
Which performance metrics do you calculate?
DSCR, cap rate, LTV, NOI, ROI and cash-on-cash return, per asset and rolled up across the portfolio — plus cash-flow stability, vendor concentration and interest-rate risk. They are computed from your actual transactions and your actual loan terms, not from figures you type into a metrics screen. The performance suite is on Pro and up.
