Thinking about snapping up a $250,000 house but not sure whether your credit score will let you in the door? You’re not alone. Lenders use a handful of numbers to decide if they’ll hand you a mortgage, and the credit score is the headline act. Below we break down exactly what score you need, how it shapes your loan terms, and what you can do right now to tip the odds in your favor.
What lenders consider “good enough” for a $250k mortgage
In the United States, most banks and mortgage companies follow the guidelines set by the major credit bureaus-Equifax, Experian, and TransUnion. The FICO® scoring model still dominates, ranging from 300 to 850. Roughly speaking, here’s how the bands translate to mortgage eligibility:
- Excellent (720‑850): Almost any loan program will welcome you, often with the best interest rates.
- Very Good (690‑719): Conventional loans are a safe bet, and you’ll still see competitive rates.
- Good (620‑689): You’ll likely qualify for government‑backed loans (FHA, VA) but may face higher rates on conventional financing.
- Fair to Poor (300‑619): Options shrink dramatically; you may need a larger down payment or a co‑signer, and rates can jump sharply.
For a $250,000 home, most buyers aim for a credit score of at least 620 if they’re leaning on FHA or VA loans, and a minimum of 660‑680 for a conventional loan that doesn’t require private mortgage insurance (PMI).
How the $250,000 price tag changes the numbers
The purchase price sets the ceiling for two key figures: the loan amount and the required down payment. Lenders usually want a loan‑to‑value (LTV) ratio of 80% or lower for a conventional loan without PMI. That means:
- Loan amount = 80% of $250,000 = $200,000
- Down payment = $50,000 (20% of the price)
If you can’t muster a 20% down payment, you’ll either pay PMI or look to a program that allows a higher LTV, like an FHA loan that can go up to 96.5% LTV (only 3.5% down). However, FHA loans come with a mandatory mortgage insurance premium (MIP) that stays for the life of the loan unless you refinance.

Loan programs and their minimum credit scores
Below is a quick snapshot of the most common loan types and the credit score thresholds lenders typically enforce for a $250k purchase.
Loan Type | Minimum Credit Score | Typical Down Payment | Notes on Rates |
---|---|---|---|
Conventional a loan not insured by the government | 660‑720 (better rates at 720+) | 5%‑20% (PMI required under 20%) | Rates drop ~0.25% for every 20‑point score increase above 720 |
FHA Federal Housing Administration loan | 620 (640+ for 30‑yr fixed) | 3.5% (can be gifted) | Higher base rate; MIP adds 0.5%‑1.0% APR |
VA Veterans Affairs loan for eligible service members | 580 (no down payment required) | 0% (funding fee applies) | Often the lowest rates; no PMI |
USDA Rural development loan | 640 (some lenders accept 620) | 0% (subject to income‑area eligibility) | Rates comparable to FHA; limited to rural locations |
Why your credit score shapes the interest rate (and monthly payment)
The mortgage rate you lock in directly influences how much you’ll pay each month. As a rule of thumb, a 20‑point increase in credit score can shave roughly 0.15%‑0.25% off the APR. Let’s see a quick example:
- Loan amount: $200,000 (80% LTV)
- Scenario A - Score 680: 4.75% APR, 30‑year fixed → $1,044 monthly principal & interest.
- Scenario B - Score 720: 4.25% APR → $985 monthly principal & interest.
That $59 difference adds up to over $2,100 in savings over the life of the loan. The gap widens if you’re borrowing more (e.g., a 90% LTV loan) or if rates rise market‑wide.
Other underwriting factors that matter alongside the score
Even with a perfect credit score, lenders look at three extra boxes before saying “yes.”
- Debt‑to‑Income Ratio (DTI) total monthly debt payments divided by gross monthly income - most lenders cap DTI at 43%, though some programs stretch to 50% with strong compensating factors.
- Employment History stable job for at least two years - gig‑workers may need additional documentation.
- Loan‑to‑Value (LTV) ratio of loan amount to home appraised value - lower LTV equals lower risk, which can offset a middling score.
When you line up a solid DTI, steady job, and a modest LTV, lenders can be more forgiving on the credit score.

Steps to boost your credit score before applying
If you’re sitting at 620‑650 and want to move into the “good‑rate” zone, here’s a pragmatic checklist you can start today:
- Check your credit reports. Pull free reports from annualcreditreport.com and dispute any errors-one wrong late payment can shave 30‑50 points.
- Pay down revolving balances. Aim for a credit utilization under 30%, ideally under 10% for the fastest score lift.
- Avoid new credit inquiries. Each hard pull can dip the score by 5‑10 points and stays on the file for two years.
- Set up automatic payments. Consistently on‑time payments are the biggest driver of score growth.
- Keep old accounts open. Length of credit history matters; closing a decade‑old card can hurt.
Following these steps for three to six months can often push a score 30‑50 points upward-enough to shave a quarter point off the rate.

Ideal Credit Score | 720+ (best rates) |

Frequently Asked Questions
What is the cheapest way to finance a $250,000 home?
For most buyers, a VA loan (if you’re eligible) or a well‑priced conventional loan with a 20% down payment will give the lowest overall cost because they avoid both PMI and the government‑backed loan fees.
Can I buy a $250,000 house with a credit score under 600?
It’s very tough. You’d need a large cash reserve for a 30%‑plus down payment, a very low DTI, and possibly a private lender willing to charge a high rate. Most traditional lenders won’t approve under 600.
How long does it take for a credit score improvement to show up?
Most credit bureaus update scores every 30‑45 days. If you’ve paid down balances and cleared errors, you’ll likely see a bump within two to three billing cycles.
Do I need a higher score for a 30‑year loan versus a 15‑year loan?
Lenders view shorter‑term loans as lower risk, so a 15‑year mortgage may accept slightly lower scores (e.g., 640) and still offer competitive rates.
Will a co‑signer help me qualify with a lower credit score?
Yes. A co‑signer with a strong credit profile can boost your application, but the lender will still evaluate the combined DTI and may require the co‑signer’s income documentation.
