Flagstar is a hybrid retail bank and large mortgage servicer. The 2022 acquisition by New York Community Bancorp added complexity to the loss mitigation process — and most homeowners run into it without warning.
The "waterfall" is the order in which Flagstar reviews options when a borrower asks for help. Knowing the order — and what each option actually delivers — tells you what to ask for and what to push back on.
Spread arrears over 3–9 months. Conservative — Flagstar prefers documented stability.
Typically 3–6 months. Flagstar requires monthly check-in calls during the forbearance period.
Standard GSE Flex Mod for conventional loans; FHA-HAMP for FHA. Review takes 60–90 days from complete file.
Approved with proper hardship documentation. Flagstar requires HUD-1 review and 30 days of marketing time minimum.
Available after a documented short-sale attempt. Cash-for-keys relocation: $3,000–$10,000 typical.
Behind on payments or facing an auction? We buy houses in any condition, can stop the sale, and close on your timeline.

Every servicer has its own quirks. The patterns below are what trips up homeowners who try to navigate Flagstar alone.
Following the NYCB acquisition, document handling and decisioning timelines have stretched. Files that would have closed in 60 days are now averaging 90+. Submit early.
Flagstar services loans for hundreds of investors. Modification approval is gated by investor guidelines — often the same hardship gets a different answer depending on who owns the loan.
Flagstar's portal is older. Many borrowers cannot upload documents over 10MB. Splitting PDFs is required.
When foreclosure is referred to the law firm, Flagstar's customer-facing reps lose visibility. You must work directly with the foreclosure attorney named in the Notice of Default to confirm any postponement.
If a sale date has been scheduled, you have a narrow window to act. Here's the sequence we follow:
A first denial is not the end. Most successful modifications are approved on appeal or after a Notice of Error is filed under RESPA Section 6.
Probably not, if Flagstar was only servicing your loan. Flagstar Bank sold its mortgage servicing business to Mr. Cooper, and the sale closed on November 1, 2024. The deal included servicing rights and Flagstar's work as a subservicer for other lenders.
Since then, more changes followed:
The fastest way to know who has your loan today is your most recent statement or transfer letter.
A transfer changes who you pay and who you talk to. It does not change your loan terms, your interest rate, or the amount you owe. Federal law (RESPA Section 6 and Regulation X §1024.33) gives you these protections:
If you get a transfer letter while you are asking for help, save it, write down the date, and call the new servicer to confirm they have your full file.
Use the contact that matches the name on your latest statement. Here is what the servicers publish on their own sites:
| If your statement says | Official contact path |
|---|---|
| Mr. Cooper or Rocket | Mr. Cooper's page for transferred Flagstar customers directs you to sign in at Rocket.com or call (800) 4-ROCKET (Mon–Fri 8:30 a.m.–9 p.m. ET, Sat 9 a.m.–4 p.m. ET). |
| M&T Bank | M&T's Flagstar customer page lists 1-888-668-5353 for mortgage customers after the February 2025 transfer. |
| Flagstar | Use the phone number and address on your Flagstar statement. |
When you call, say the words "I need to apply for mortgage assistance" and ask for the application to be sent to you or started online. Write down the date, the name of the person, and any reference number.
Your monthly statement is the final word. The servicer name, phone number, and mailing address printed on your most recent statement or on a transfer letter are the ones that apply to your loan. Use those over any number you find online, including this page. Scammers often pose as servicers, so never pay a fee to anyone who promises to "save" your home (see foreclosure scams to avoid).
Whether your loan is now with Rocket, M&T, or still with Flagstar, the core package is usually the same.
| Document | Why they ask |
|---|---|
| Mortgage assistance application (often Fannie Mae/Freddie Mac Form 710 or the servicer's own form) | Your income, expenses, and what kind of help you want |
| Hardship letter or statement | What happened, when it started, and whether it is short-term or long-term |
| Proof of income (recent pay stubs, benefit award letters, or profit-and-loss statement if self-employed) | Shows what payment you can afford now |
| Recent bank statements (usually the last two) | Confirms income deposits and savings |
| Tax return and/or IRS Form 4506-C | Lets them verify income with the IRS |
| Hardship proof if it applies (divorce decree, death certificate, job-loss or transfer letter) | Backs up the reason you fell behind |

Flagstar sold its mortgage servicing business to Mr. Cooper in November 2024, and Rocket Companies bought Mr. Cooper in October 2025. Some Flagstar-serviced loans owned by Lakeview moved to M&T Bank in February 2025. Your latest statement or transfer letter shows who services your loan.
No. A servicing transfer changes who collects your payment and handles your account, not your interest rate, balance, or loan terms. The new servicer must follow your original loan documents.
Under Regulation X §1024.41(k), a pending assistance application must be passed to the new servicer, which must keep to the timelines that applied before the transfer. Call the new servicer to confirm they have your complete file.
For 60 days after the transfer, a payment sent on time to the old servicer cannot be treated as late. Contact the new servicer to make sure the payment was forwarded and applied.
Often yes, but time matters. Apply for assistance right away, and call a HUD-approved counselor at 1-800-569-4287 or a local foreclosure attorney. Our how to stop foreclosure guide explains the main options.
Most modifications we close were originally denied. Our team knows how to read the denial reason and structure the appeal. No upfront fees, ever.
