# Mortgage Pre-Approval Checklist for Michigan Home Buyers By Kate Young (@kateyoung) · Published 2026-10-26 Canonical: https://voce.com/@kateyoung/mortgage-pre-approval-checklist-michigan-home-kcn6z5 --- A mortgage **pre-approval letter** tells sellers and agents how much a lender is generally willing to lend you, based on a real review of your finances — not numbers you typed into a calculator. For first-time buyers, it's the document that makes your offer competitive, and it requires proof of **income, assets, debt, and identity**. In a market like Bay City, where move-in-ready starter homes draw multiple offers, a pre-approval letter is what separates a serious buyer from a tire-kicker. Gather it once, correctly, and you'll move from application to house hunting in days instead of weeks. ## What documents do you need for mortgage pre-approval? Lenders ask for the same four categories of documents no matter where you buy: **identification, proof of income, asset statements, and a list of your debts**. As a Bay City REALTOR, I tell every first-time buyer the same thing: the paperwork is how the lender confirms your income and assets are real and stable — and it's what your file is judged on. Borrowers applying for pre-approval will likely need documents such as W-2s, bank statements, a credit report and tax returns ([Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements)) — though the exact list varies by lender and loan type. The paperwork exists to answer one question: can you actually afford this loan, and is the income that pays for it real and stable? Each document verifies a different part of that story. Document Category What Lenders Verify Why It Matters **Identification** Government-issued photo ID and Social Security number Confirms you're the person borrowing, not an identity thief **Income** Pay stubs, W-2s, tax returns, employer info Proves steady, sufficient earnings to cover the mortgage **Assets** Bank, investment, and retirement account statements Shows you have cash for the down payment, closing costs, and reserves **Debt** Credit cards, auto and student loans, other recurring payments Lets the lender calculate your debt-to-income ratio ## Proof of income: what shows you can make the payments Income documents are the heart of a pre-approval because they show the lender you earn enough to cover the mortgage every month. For a salaried employee, that means your **two most recent pay stubs, W-2s for the last two years, and your last two years of tax returns**, plus your employer's name and contact information ([Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements)). Lenders typically ask to see pay stubs from at least the last 30 days. Lenders love consistency in employment. If you've recently switched jobs, a move within the same industry at similar pay usually proceeds as expected, but a change in industry or pay structure may prompt a reassessment of your situation, according to [Rocket Mortgage](https://www.rocketmortgage.com/learn/mortgage-preapproval-checklist). ![A house-shaped keychain and a calculator resting on mortgage paperwork](https://images.unsplash.com/photo-1732812608429-67bd0ff463ae?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&ixid=M3w5Mzk0NDN8MHwxfHNlYXJjaHwyfHxtb3J0Z2FnZSUyMGRvY3VtZW50cyUyMGNoZWNrbGlzdCUyMGRlc2slMjBob3VzZSUyMGtleXMlMjBjYWxjdWxhdG9yfGVufDB8MHx8fDE3OTMwMzY0NjZ8MA&ixlib=rb-4.1.0&q=80&w=1200&h=630) **Self-employed buyers** face a longer paper trail. Because the lender has to verify income stability and how business income is treated on taxes, you'll generally need personal and business tax returns, a year-to-date profit-and-loss statement, a balance sheet, or business bank statements ([Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements)). A borrower whose income shows up on a 1099, a K-1, or a Schedule C must produce a year-to-date profit-and-loss statement signed and dated within 60 days of application, plus the most recent two business tax returns ([Fellowship Home Loans](https://fellowshiphomeloans.com/three-pre-approval-documents-buyers-always-forget)). #### Key Takeaways - Pre-approval is not final approval — the loan still goes through underwriting and appraisal before closing - Bring four categories of documents: income, assets, debt, and identification - The forgotten items — letter of explanation, gift letter, and P&L for the self-employed — delay the most files - Michigan's MSHDA MI Home Loan offers up to $10,000 in down payment assistance to qualifying first-time buyers ## Proof of assets: showing you have the cash to close Asset documents prove you have money saved for the down payment and closing costs, plus a cushion if your income is ever interrupted. You'll generally be asked for **checking and savings account statements for the last two months**, and lenders may also want to review statements from investment and retirement accounts like 401(k)s, IRAs, stocks, and bonds over the same period ([Rocket Mortgage](https://www.rocketmortgage.com/learn/mortgage-preapproval-checklist)). What the lender is really scrutinizing is the trend: a steady, growing balance reads as savings discipline, while a balance that dips into overdraft every month raises a flag about whether the mortgage payment will be affordable. Two months of statements lets the lender spot **large or unexplained deposits**. A deposit larger than 50% of your monthly income triggers a letter of explanation, and an undocumented source of funds can force the lender to reissue its Loan Estimate, restarting a waiting period that pushes your close back ([Fellowship Home Loans](https://fellowshiphomeloans.com/three-pre-approval-documents-buyers-always-forget)). That's why it pays to keep your money in one or two accounts during the process and to avoid moving large sums around right before you apply. ## Proof of debt: the numbers behind your debt-to-income ratio The debt list tells the lender how much of your income is already committed. Your **debt-to-income (DTI) ratio** compares your monthly debt payments to your gross monthly income — you add up all your monthly payments and divide by your income. The maximum allowed varies by loan type, and while it's possible to get a mortgage with a DTI as high as 50%, it's advisable to keep it below 36% ([Rocket Mortgage](https://www.rocketmortgage.com/learn/mortgage-preapproval-checklist)). Lenders scan this list less for the exact balances and more for the pattern: minimum-only credit card payments and a student loan that keeps growing tell a different story than debts being paid down steadily. You'll be asked for a list of fixed, recurring debts: credit cards, auto loans, student loans, personal loans, rent, and any child support or alimony you pay. The lender also pulls your **credit report** on its own once you give permission, and in many cases you'll need a credit score of at least 620 for a conventional mortgage pre-approval ([Rocket Mortgage](https://www.rocketmortgage.com/learn/mortgage-preapproval-checklist)). ## Identification and the paperwork buyers forget Identity documents are simple but non-negotiable: a **government-issued photo ID** like a driver's license or passport, plus your **Social Security number**. Some lenders also want to see the physical Social Security card to match the number against your ID ([Rocket Mortgage](https://www.rocketmortgage.com/learn/mortgage-preapproval-checklist)). Beyond the standard stack, three documents trip up more applications than any others. According to [Fellowship Home Loans](https://fellowshiphomeloans.com/three-pre-approval-documents-buyers-always-forget), roughly 60% of post-application stipulation requests come from these three: a **letter of explanation** (required for any inconsistency, like a 30-day late payment years ago, a job gap, or a large deposit), a **gift letter** with a paper trail (when family money funds your down payment), and a **year-to-date profit-and-loss statement** for self-employed borrowers. A gift letter must state the dollar amount, the relationship, and that no repayment is expected — and you pair it with a copy of the donor's bank statement and a deposit receipt from the day the funds landed ([Fellowship Home Loans](https://fellowshiphomeloans.com/three-pre-approval-documents-buyers-always-forget)). Verbal reassurances that a parent is helping don't count. ## Why Michigan's down payment programs change your paperwork If you're a first-time buyer, the documents you need may shift depending on the **Michigan State Housing Development Authority (MSHDA)** program you use. The flagship **MI Home Loan** is a 30-year fixed-rate mortgage for first-time home buyers that can be underwritten as a conventional, FHA, VA, or USDA loan, with a 640 minimum credit score and a maximum sale price of $566,355 ([ConsumerAffairs](https://www.consumeraffairs.com/finance/michigan-first-time-homebuyer-programs.html)). It pairs with the **MI 10K Down Payment Assistance** program, which provides up to $10,000 in an interest-free loan you can use toward your down payment, closing costs, or prepaid expenses ([ConsumerAffairs](https://www.consumeraffairs.com/finance/michigan-first-time-homebuyer-programs.html)). That down payment assistance can come as **gifted or borrowed funds**, which is exactly when the gift letter and its paper trail become essential. If a family member helps you, the lender needs a signed gift letter stating the amount, the relationship, and that no repayment is expected, plus proof the money left the donor's account ([Fellowship Home Loans](https://fellowshiphomeloans.com/three-pre-approval-documents-buyers-always-forget)). ![A model house and a calculator resting on a desk with paperwork](https://images.unsplash.com/photo-1775590766317-8fd3ef7d721c?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&ixid=M3w5Mzk0NDN8MHwxfHNlYXJjaHwzfHxtb3J0Z2FnZSUyMGRvY3VtZW50cyUyMGNoZWNrbGlzdCUyMGRlc2slMjBob3VzZSUyMGtleXMlMjBjYWxjdWxhdG9yfGVufDB8MHx8fDE3OTMwMzY0NjZ8MA&ixlib=rb-4.1.0&q=80&w=1200&h=630) Some MSHDA programs are **paused** while they wait for fresh funding — including the MSHDA Rate Relief Mortgage Program and the MSHDA First-Generation Down Payment Assistance Program ([ConsumerAffairs](https://www.consumeraffairs.com/finance/michigan-first-time-homebuyer-programs.html)). A local lender who works with MSHDA-approved programs can tell you what's currently open and what documentation your specific loan type requires, because the list genuinely changes by program. ## Your pre-approval checklist, ready to gather Here's the complete list to bring to your first lender conversation. This is a lot of paperwork the first time, but most of it is easy to pull from a payroll portal and your bank app. It matches the document categories lenders review — income, assets, debt, and identity — as [Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements) outlines for pre-approval, and each item verifies a different part of your ability to repay. 1. **Identification:** Government-issued photo ID and Social Security number (or card) 2. **Income:** Two most recent pay stubs, two years of W-2s, two years of tax returns, employer contact info 3. **Self-employed add-ons:** Two years of business tax returns and a year-to-date profit-and-loss statement 4. **Assets:** Two months of checking and savings statements, plus investment and retirement statements 5. **Debt:** List of credit cards, auto and student loans, and other monthly payments 6. **Rental history:** Landlord contact information and proof of on-time rent payments, if you rent 7. **Letter of explanation:** Written on anything that raises a question — a job gap, a large deposit, an old late payment 8. **Gift letter with paper trail:** Only if family funds part of your down payment The smartest move is to organize these into a single digital folder, named and dated, before you apply. Borrowers who arrive with a clean file save the underwriter a phone call and shave days off the timeline. ## What happens after pre-approval A pre-approval letter is a strong starting point, but it is **not a final loan offer**. After you make an offer and the property is under contract, the loan still goes through underwriting, an appraisal, a title review, and a fresh credit and employment check before closing ([Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements)). Your financial picture can change between pre-approval and closing, so don't open new credit, change jobs, or move large sums of money in the meantime. Pre-approval letters also **expire** — many are valid for a limited time, often 30 to 60 days, and may need to be refreshed ([Lower](https://www.lower.com/mortgages/mortgage-pre-approval-letter-requirements)). If yours lapses while you're still house hunting, you'll simply reissue it with updated documents. If you're starting this process in the Bay City area and want a local hand holding yours through it, I'd be glad to walk you through the paperwork and connect you with lenders who know the MSHDA programs inside out. Pre-approval feels like a mountain of forms, but it's really just your financial story told clearly, once, so a lender can say yes with confidence.
