The average purchase loan in this country closed in 36.8 days in March 2026, the fastest pace since ICE Mortgage Technology began tracking the metric in 2019, according to the ICE Mortgage Monitor released May 11, 2026. Buried inside that headline is the number that should actually shape your decision: the typical purchase loan moved from application to rate lock in 11 days, then spent another 26 days between the lock and the closing table.
Almost nobody blows a rate lock because rates moved. They blow it because a condo questionnaire sat on somebody's desk.
Twenty-six days. That is the national picture, and it describes a market where the collateral is a house and the file runs in a straight line. If you are buying a condo in Miami-Dade, that number is not describing your deal.
What You're Actually Buying When You Lock
A rate lock is the lender committing to hold a specific rate and price for a set number of days while underwriting works your file. It has an expiration stamp on it. The moment you take it, the lender hedges that commitment in the secondary market against a delivery window, which is exactly why moving the window later costs money. Extension fees are not a penalty invented to annoy you. Somebody bought protection for a date you missed.
Your Loan Estimate tells you where you stand, and it is not ambiguous. Federal rule 12 CFR 1026.37(a)(13) requires page one to state whether the interest rate is locked and, if it is, the date and time the lock expires.
If the lock date and time are not printed on your Loan Estimate, you are not locked.
Read that box. A surprising number of buyers believe they are locked because a loan officer texted them something reassuring about rate. A text is not a lock. And if you were floating when your original Loan Estimate went out, and locking changes your points or lender credits, your lender owes you a revised Loan Estimate within three business days of the lock under 12 CFR 1026.19(e)(3)(iv)(D).
The Miami Condo Problem
Everywhere else, lock length is a rate strategy question. In Miami-Dade it is a document question, and the documents live with a property manager who does not work for you and has no reason to care about your closing date.
Condo project review is the choke point. Before your loan can close, an underwriter needs the association questionnaire, the operating budget, reserve documentation, a certificate showing the master insurance policy is in force, and a disclosure of any pending litigation. Five items, five separate humans, and no contractual obligation to any of them to be quick about it. A house has none of this. A house stands or falls on its own appraisal.
Florida then made those files considerably heavier. House Bill 913, passed in 2025, moved the initial structural integrity reserve study deadline from December 31, 2024 to December 31, 2025, and permits an association to complete the study alongside a milestone inspection due on or before December 31, 2026. Every association in the county has spent the last two years reserve-studying, re-budgeting and in plenty of cases assessing. Underwriters read those documents closely now, and a special assessment surfacing in week three of a 30 day lock is a real problem, not a formality.
Read that alongside the cash figure and Miami's contract culture starts to make sense. Realtor.com research covering the first half of 2025, cited by MIAMI REALTORS, ranked Miami first in the country for all-cash sales at 43 percent of deals. Cash buyers close in two weeks. Sellers who have been trained by cash buyers write 30 day contracts. Then a financed buyer signs one of those contracts on a condo and discovers that the building, not the borrower, sets the schedule.
A 30 day lock on a Miami condo is a bet that a property manager answers your questionnaire in two weeks.
If the building turns out to be ineligible for conventional financing entirely, the product changes and so does the timeline. Our non-warrantable condo loan guide covers what happens next, and condo versus house in Miami walks through the trade before you are under contract.
Lock Lengths, Honestly
| Lock length | Realistic for | Where it breaks |
|---|---|---|
| 15 days | A refinance already through underwriting with nothing left to discover | Rarely appropriate on a purchase. One document request eats the whole window. |
| 30 days | Single-family purchase, W-2 income, inspection came back clean | Appraisal reconsideration, an insurance binder that will not issue, a title surprise |
| 45 days | Most Miami condo purchases. This is the honest default. | Association slow on the questionnaire, or a special assessment nobody disclosed |
| 60 days | Older waterfront buildings, self-employed files, non-QM products | Litigation disclosure, milestone inspection findings, layered income documentation |
| Extended locks | New construction with a delivery date months out | Builder delay, and the gap between a temporary and a final certificate of occupancy |
Longer locks price worse. That is unavoidable, because the lender is hedging a longer exposure and charges you for the time. But the difference between a 30 and a 45 day lock is a known, small, quotable number you can decide about today. The cost of blowing a lock is unknown and gets decided by whatever the bond market does the week you run out of days. Trading a known small cost for an unknown one is a bad habit.
Buying preconstruction changes the math again, and our new construction guide for Miami buyers covers extended lock structures and delivery-date risk in detail.
Extensions, and Who Actually Pays
Extension pricing is a fraction of a point on the loan amount, charged per day or in blocks, and it gets steeper the further you push. Most people meet this pricing for the first time on the day they need it, which is the worst possible negotiating position. Ask for the schedule in writing when you lock.
Then there is the fairness question, which is not a legal question at all. Nothing entitles you to make the seller pay for a delay their association caused. But nothing stops you from asking, either, and the ask lands very differently when it comes with a paper trail. If you requested the condo questionnaire on day two and the management company took eighteen days, put that in writing at day ten, not at day twenty-nine. Extension costs get absorbed as a seller credit far more often than buyers expect, and essentially never when the request arrives as a surprise the day before closing.
Float-Downs Sound Better Than They Are
A float-down lets you capture a lower rate if the market improves while you are locked. It sounds like free insurance. It is neither free nor, most of the time, worth it.
The cost is either priced into your lock up front or charged when you exercise, and almost every float-down requires the market to move by a minimum threshold before the option activates at all. On a 30 or 45 day window, paying for an option that only pays off after a meaningful move is a lottery ticket with a fee attached. Read the trigger. Read the exercise window. If your loan officer cannot state both numbers without going to check, that is your answer.
The ordinary tool for capturing a real rate improvement is a refinance later, and it has the advantage of being a decision you make with actual information rather than a bet you place in advance. Our guides on when refinancing is worth it and rate and term refinancing cover the math.
The Two Clocks People Confuse
Your lock clock and your federal disclosure clock are separate, and they do not move together. Confusing them is how a file that was fine on Tuesday closes the following Monday.
Under 12 CFR 1026.19(f)(1)(ii)(A) you must receive the Closing Disclosure at least three business days before consummation. Under 12 CFR 1026.19(f)(2)(ii), a fresh three business day waiting period starts over if any of three things happen: the annual percentage rate becomes inaccurate, the loan product changes, or a prepayment penalty is added.
That first trigger is the one that touches rate locks. A re-lock at different pricing can move your APR. For a regular transaction the APR is treated as accurate within one-eighth of one percentage point under 12 CFR 1026.22(a)(2), so a modest change costs you nothing and a larger one costs you three business days you did not budget.
A re-lock that moves your APR beyond one-eighth of a point can add three business days to your closing.
Nobody mentions this until the day it happens. Ask the question before you agree to a re-lock, especially if your lock expiration and your contract closing date are sitting within three days of each other. They should not be.
When It Expires Anyway
Most lenders re-lock an expired commitment at worst-case pricing: the worse of your original rate or the current market. The asymmetry is deliberate and it is not negotiable at most shops. Rates fell while your file sat? You do not get the improvement. Rates rose? That is yours. Some lenders also impose a cooling-off period before an expired lock can be re-priced at market at all.
The Week Before You Lock
- Request the condo questionnaire the day you go under contract, not the day the underwriter asks for it. This one habit saves more locks than anything else on this list.
- Ask the association three things in writing: is a special assessment pending, is there active litigation, and when were the milestone inspection and reserve study completed.
- Bind insurance early. South Florida carriers are not fast, wind and flood coverage may come from separate policies, and a binder that will not issue stops a closing cold. Our Miami homeowners insurance guide covers what actually gets covered.
- Get the extension fee schedule and any float-down terms in writing, before you need either one.
- Compare your contract financing contingency date against your lock expiration date. If they land on the same day, you have no room at all.
- If your income is self-employed, commission-based or documented through bank statements, add days. Those files ask more questions and every question is a round trip.
Do the front half of this before you write an offer and you will lock with real information. Our Pre-Qualification guide covers what to have ready, the Miami appraisal guide explains the step most likely to add days in the middle, and the closing costs guide shows where extension fees land on your final numbers. Buying in a high-rise market like Brickell makes every one of these steps more consequential, because nearly all of the inventory is condo.
Lock length is not a market call. It is an honest estimate of how long the slowest person in your transaction takes to answer an email. In Miami-Dade, that person usually manages a condo building.
