Taking out a loan for an apartment runs along one of two tracks. If you need money to cover a security deposit, first and last month’s rent, or moving expenses, you’ll apply for a personal loan, with rates that typically range from about 7% to 36%. If you’re buying a condo or co-op, you’ll apply for a mortgage, which can require as little as 3% down on a conventional loan or 3.5% down on an FHA loan. Either path puts you through credit checks, income verification, and a set of federal disclosure rules built to protect you from surprises.
Which Loan You Actually Need
A personal loan is unsecured. You borrow a lump sum, repay it over a fixed term (usually two to seven years), and the lender has no collateral. Because the lender takes on more risk, interest rates run higher and approval leans heavily on your credit and income. This is the right product for renters who need cash to move in.
A mortgage is secured by the apartment itself, which is why rates are far lower. For apartment purchases, two mortgage types dominate. Conventional loans follow Fannie Mae or Freddie Mac guidelines. FHA loans are insured by the Federal Housing Administration and accept lower credit scores and smaller down payments, but they require mortgage insurance for the life of the loan if you put less than 10% down. Conventional loans give you more flexibility once you build equity; FHA loans give you an easier door to walk through at the start.
Credit, Income, and Employment Requirements
Credit Score
FHA loans have the clearest cutoffs. A FICO score of 580 or above qualifies you for the minimum 3.5% down payment. Scores between 500 and 579 still qualify but push the down payment to 10%. Below 500, FHA financing is off the table.
On the conventional side, Fannie Mae historically required a 620 minimum FICO. That changed in late 2025, when Fannie Mae removed the hard 620 floor for loans run through its automated underwriting system and let the system evaluate overall risk instead.1Fannie Mae. Selling Guide Announcement SEL-2025-09 Most individual lenders still set their own floors, so 620 is still what you’ll run into shopping around. Manually underwritten conventional loans continue to carry Fannie Mae’s eligibility-matrix minimums.
Personal loan lenders each set their own threshold. Expect to need somewhere around 580 to 620 for competitive rates.
Debt-to-Income Ratio
Your debt-to-income ratio compares your total monthly debt payments to your gross monthly income. Fannie Mae caps this at 36% for manually underwritten loans, with room up to 45% for borrowers with strong credit and cash reserves. Loans run through Fannie Mae’s automated system can be approved with ratios as high as 50%.2Fannie Mae. B3-6-02, Debt-to-Income Ratios The 43% figure that gets quoted everywhere came from a qualified mortgage rule the CFPB replaced in 2022, so treat it as a frequently cited number, not a universal ceiling.
Employment History
Fannie Mae recommends a two-year employment history, though income earned over a shorter period (no less than 12 months) may count if other factors offset the shorter track record.3Fannie Mae. Standards for Employment-Related Income You don’t need to have stayed at the same job. Moving between positions in the same field is fine as long as the pattern looks reliable.
Down Payment and Mortgage Insurance
Conventional loans allow down payments as low as 3% of the purchase price for qualifying borrowers. FHA loans require at least 3.5% with a 580-plus credit score, or 10% for scores between 500 and 579.
Putting less than 20% down on a conventional loan triggers private mortgage insurance (PMI). It protects the lender if you default and typically costs between 0.5% and 1.9% of your loan amount per year.4Fannie Mae. What to Know About Private Mortgage Insurance PMI doesn’t last forever. Federal law lets you request cancellation once your balance reaches 80% of the home’s original value, and your servicer must automatically terminate it at 78%, provided you’re current and have a good payment history.5Office of the Law Revision Counsel. 12 USC Ch. 49 – Homeowners Protection
FHA works differently. If you put less than 10% down, the mortgage insurance premium stays for the life of the loan.
Documents to Gather Before You Apply
Lenders verify your identity under federal anti-money-laundering rules, so you’ll need a valid government-issued photo ID. The lender will record your name, address, date of birth, and identification number as part of its customer identification program.6eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
Income documentation does the heavy lifting. If you’re a wage earner, expect to provide your two most recent W-2s and pay stubs covering at least the last 30 days. Self-employed borrowers typically submit two years of signed federal tax returns and any 1099s.
For a mortgage, add two months of statements for all checking, savings, and investment accounts.7Fannie Mae. Verification of Deposits and Assets Underwriters read these line by line for deposits that don’t match your paycheck. Anything unusual needs a paper trail. Money that has been in your accounts for at least 60 days is generally considered seasoned and won’t trigger questions. If a relative is gifting you down payment money, deposit it well before you apply and keep the gift letter on hand.
Personal loan applications are lighter. The same income verification applies, but there’s no asset documentation and no property paperwork because there’s no collateral.
Pre-Approval and the Application
Before you start apartment hunting, mortgage lenders offer two levels of preliminary review. A pre-qualification is a quick estimate from self-reported numbers, sometimes with a soft credit pull. It gives you a ballpark and little else. A pre-approval goes further: the lender pulls your credit, verifies income and assets, and issues a conditional commitment for a specific loan amount. Sellers and their agents treat the pre-approval letter as evidence you can actually close, and showing up without one in a competitive market puts you at a real disadvantage.
The full application comes next, usually through a digital portal. You’ll report gross monthly income (the total before taxes and withholdings) and list your existing debts so the lender can calculate your DTI.
On a mortgage application, the only fee a lender can charge you before delivering the Loan Estimate is a credit report fee, which is typically under $30.8Consumer Financial Protection Bureau. How Much Does It Cost to Receive a Loan Estimate? Application fees, appraisal charges, and the rest come later. If a lender pushes you to pay more upfront before you’ve seen the Loan Estimate, push back.
Electronic signatures carry the same legal weight as ink. Federal law says a contract or signature cannot be denied legal effect simply because it’s in electronic form, so signing through the lender’s online platform is binding.9Office of the Law Revision Counsel. 15 USC Ch. 96 – Electronic Signatures in Global and National Commerce
If your income or credit falls short, a co-signer can get the application approved. The co-signer takes on full legal responsibility for the debt. The lender can pursue them for the whole balance if you stop paying, and their credit absorbs any missed payments. Lenders will verify a co-signer’s income, assets, and credit as carefully as yours.
Underwriting and Appraisal
After submission, the underwriting team picks apart what you provided. They verify employment directly with your employer, match your deposits against your pay stubs, and flag inconsistencies. The review can take days or weeks. Expect follow-up requests, especially if your income is variable or your statements show anything unusual.
For a mortgage, the lender orders a professional appraisal. An independent appraiser visits the unit, evaluates its condition, compares it against recent sales of similar properties, and estimates market value. If the appraisal comes in below the purchase price, the lender won’t finance the full amount, and you’ll need to renegotiate with the seller, cover the gap in cash, or walk away.
Federal law entitles you to a copy of the appraisal report promptly after it’s completed, or at least three business days before closing, whichever comes first.10Consumer Financial Protection Bureau. Regulation B 1002.14 – Rules on Providing Appraisals and Other Valuations You get a copy whether or not the loan is approved.
Closing Costs and Fees
Mortgage closing costs typically run between 1.5% and 4.5% of the loan amount, with smaller loans landing at the higher end because many fees are fixed regardless of size. The total bundles the origination fee, appraisal, title insurance, recording fees, and prepaid items like homeowners insurance and property taxes.
Discount points are an optional cost that cuts your interest rate. One point costs 1% of your loan amount and usually drops your rate by about a quarter of a percentage point. Paying points pays off if you stay in the apartment long enough for the monthly savings to outrun the upfront cost.
Personal loan costs are simpler. Some lenders charge an origination fee (often 1% to 8% of the loan amount); others charge nothing upfront and build the cost into the rate. There are no appraisal, title, or recording fees.
Federal Protections to Lean On
Two mortgage disclosures do most of the consumer-protection work. Within three business days of receiving your application, the lender must deliver a Loan Estimate showing your estimated interest rate, monthly payment, closing costs, and other loan terms. Use it to compare offers from different lenders. At least three business days before closing, you must receive a Closing Disclosure showing the final terms and all costs. Read it against your Loan Estimate line by line. Certain changes to the APR, loan product, or the addition of a prepayment penalty after the Closing Disclosure is issued trigger a new three-day waiting period.11eCFR. 12 CFR 1026.19 – Certain Mortgage and Variable-Rate Transactions
If a lender denies your application, federal law requires written notice within 30 days of your completed application, and the notice must identify the specific reasons for the denial. Vague explanations don’t satisfy the rule.12Office of the Law Revision Counsel. 15 USC 1691 – Scope of Prohibition Use those reasons to decide what to fix before applying again.
Where to Apply
Traditional banks offer the full range of mortgage and personal loan products. Their underwriting tracks Fannie Mae and FHA guidelines closely, which suits borrowers with a straightforward financial profile. Credit unions often beat banks on rates because they operate as nonprofits and return surplus to members, and many have broadened membership well beyond their original employer or geographic base.
Online lenders and fintech platforms compete on speed. Automated systems can return pre-approval decisions in minutes, and some fund personal loans within a day or two of approval. The tradeoff is less hand-holding. If your application has complications like self-employment income, employment gaps, or unusual asset sources, a loan officer at a bank or credit union may work through those issues more effectively than an algorithm.
A Note on Taxes
If the loan is a mortgage on your primary residence, you can deduct mortgage interest on up to $750,000 of loan principal ($375,000 if married filing separately) when you itemize. For mortgages originating before December 16, 2017, the limit is $1 million.13Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction Personal loan interest is not deductible; the IRS treats it as nondeductible personal interest.14Internal Revenue Service. Topic No. 505, Interest Expense If you’re borrowing for a deposit or moving costs, keep the amount small and pay it off quickly.
