Why Most Investors Ignore Their Loan Terms—And How It Blindsides Them at Refi

You've underwritten the deal perfectly.
The rent is solid. Expenses are real. The market makes sense. You're ready to buy.
Then the lender sends the term sheet.
Most investors skim it and sign.
That's the mistake.
Your Loan Terms Are Your Underwriting
Your loan doesn't just affect your monthly payment—it dictates your exit strategy, your refi path, and whether you're stuck or flexible when the market shifts.
And almost nobody builds that into their underwriting model.
The deal only works if you can actually refinance on your timeline, at a stress-tested rate, without a penalty that blows up your math.
That means you need to know—before you sign—what the lender will actually allow you to do and when.
The Two Terms That Matter Most
1) The lockout period.
This is how long you have to hold the deal before you can refinance without paying a penalty.
Most loans have a 3-5 year lockout.
If your business plan calls for a refi at year 3 and you hit a 5-year lockout, you just extended your hold by two years you didn't budget for.
That extension costs you. In a flat market, it's just carry. In a declining market, it's death.
2) The defeasance clause.
Some loans require you to refinance into a new loan with the same lender when the lockout ends.
Others let you pay the loan off and walk away.
If rates spike and the lender won't refi you at a reasonable cost, a defeasance deal forces you to stay in a bad marriage.
You lose optionality. And optionality is what saves you when assumptions go wrong.
What Actually Happens
You model a 5-year hold with a year-5 refi at 5.5%.
You hit year 5. Rates are now 7%.
Your debt service went up 200+ basis points overnight.
Your exit cap is tighter. Your proceeds are lower. Your return swings hard negative.
Then you realize the lockout doesn't lift until year 5.5, and the lender wants a 1.5% prepayment penalty if you pay it off early.
You're trapped. You can't refi favorably. You can't pay it off. You're stuck carrying a deal that no longer makes sense.
How to Build Loan Terms Into Your Model
Start by asking the lender (or your broker) for the exact lockout end date and what prepayment penalties apply if you want to exit before that date.
Then build a refi scenario into your underwriting.
Stress the exit cap up 100 basis points from your year-5 assumption.
Run the math with a 6.5% refi rate instead of a 5.5% assumption.
See if the deal still pencils.
If it doesn't, you need a wider margin of safety on the entry price—or you walk away.
The Real Problem
Most investors don't do this because they think loan terms are "just legal stuff."
They're not. They're part of your financial structure.
A loan with a long lockout and a defeasance clause is a different investment than one with a 1-year call and a clean exit.
If you're pricing the deal the same way for both, you're taking on hidden risk without compensation.
The discipline to walk away from a deal with unfavorable loan terms is what makes your "yes" mean something.
