What's the Difference Between ACORD 24 and ACORD 27 for Homes?
ACORD 24 is the evidence-of-insurance form lenders use for homes. ACORD 27 is an older version, now mostly replaced by the 28.

Your lender will tell you which form it wants, and that answer settles the question. Most lenders now ask for ACORD 25 or ACORD 24, which confirms your house is insured and lists the lender as a party with an interest in the property, called the mortgagee. ACORD 27 was built for manufactured homes and has largely been replaced by ACORD 28 for that purpose. If your closing paperwork names a specific form, pass that name to whoever is writing your policy rather than guessing which one applies to a regular single-family home.
The paperwork isn't the whole policy
Your lender's proof of insurance confirms a policy exists. It says nothing about dwelling coverage, deductibles, or what you pay each year. Those numbers vary by insurer, and comparing them before closing is worth the time.
Who actually fills out the ACORD form
You won't be the one typing in ACORD 24 or ACORD 27. The insurance agent or company writing your policy prepares it and sends it to your lender directly, or to the title company handling your closing. Your part is simpler than that. Get a policy in place, give the insurer your lender's name and mailing address or loan number, and confirm the lender got what it needed. Ask the agent to send you a copy too, so you know it went out and what it says.
A binder is a separate, short document that does similar work before the full policy exists. It states that coverage starts on a given date, names the dwelling amount and the lender, and holds until the actual policy documents are issued, usually within 60 to 90 days. Most lenders accept a binder at closing and expect the ACORD form or a full policy to follow soon after. If your closing is coming up fast, ask the insurer whether they can issue a binder right away rather than waiting on the formal form.
Timing matters more than the form number. Lenders typically want proof of insurance a few days before closing, not the morning of. If you're switching insurers or shopping quotes close to the date, tell every company you're talking to that you have a closing deadline. A policy that starts the wrong day, or a form sent to the wrong fax number or email at the lender, can hold up closing even when the coverage itself is fine.
Double check three things on whatever form gets sent. Your name has to match the title exactly. The property address needs to be correct. The lender's name and loan number should match what's on your closing paperwork. Errors here are common because the information passes through several hands, agent to insurer to lender, and a typo in any one of them can mean the lender treats the proof as incomplete. It's worth asking the agent to read the lender information back to you before they send it.
What to do if your closing date moves
Closing dates shift all the time, and the proof of insurance that was fine for next Tuesday might not work for three weeks from now if the policy's effective date doesn't match. If your closing gets pushed back, call the insurer before the old date passes. Most will adjust the start date on the policy and reissue the form without any trouble, but it has to be asked for. A lender comparing a binder's effective date against the actual closing date will flag a mismatch, even a mismatch of one day.
If closing moves earlier instead of later, the same problem runs the other way. You can't have a gap where the house is yours but no policy has started yet. Tell the agent the new date as soon as you know it, not the week of. Insurers can usually move an effective date up without much friction, but doing it the day before closing adds risk that something gets missed.
Rate locks and insurance timing sometimes collide in ways people don't expect. If your mortgage rate lock has an expiration date, that date and your insurance effective date should both be checked against the real closing date, not the one from a month ago that got written into early paperwork. It's easy for one of the three dates to get updated and the others to lag behind.
None of this requires you to understand the ACORD form itself in any depth. It requires keeping one date, the closing date, in front of everyone involved, the lender, the title company, and whoever is writing your policy. If you hear the date has changed from your real estate agent or the title company, pass that along to the insurer the same day. A quick phone call at that point is simpler than a stalled closing because the paperwork on file was for a date that no longer applies.
Before you sign anything
Check the effective date on your binder or policy against the actual closing date, not an earlier one from old paperwork. If they don't match, call the insurer now so what your lender receives is accurate.
