Conventional vs. FHA: Which Loan Is Easier to Get with a 600+ Score?

2. FHA Vs Conventional Loans: Minimum Credit Score Requirements For A Mortgage 

The most critical factor in deciding between a conventional mortgage vs FHA is your credit history. Your credit score acts as a gauge of your financial reliability.

When you ask, "Can I buy a house with a 600 credit score?", the answer is a resounding ‘yes.’  But, your score will heavily dictate which of these two loan avenues is actually open to you. 

The Minimum Credit Score For FHA Loan Approval

The minimum credit score for FHA loan approval is famously forgiving. 

According to HUD guidelines, you only need a FICO score of 580 to qualify for the maximum financing advantage (a 3.5% down payment).

If your score is between 500 and 579, you can still get an FHA loan, but you will be required to put down 10%.

Therefore, if you have a 600+ credit score, you easily clear the benchmark for an FHA loan's lowest down payment tier. This will be the path of least resistance for you when you want to get approved for a mortgage. 

The Minimum Credit Score For Conventional Mortgages

When it comes to the minimum credit score required to buy a house using a conventional loan, the standard benchmark has historically been 620.

Recently, Fannie Mae has shifted toward a more "holistic" underwriting approach that removes the hard 620 floor for certain loans; lenders can weigh factors like cash reserves and on-time rent payments.

However, in practical terms, most private lenders still enforce a strict 620 minimum overlay. A score of 600 will typically result in an automatic denial for a standard conventional loan.

3. Down Payment Differences: How Much Cash Do You Need?

Saving for a down payment is often the biggest hurdle for prospective homebuyers. Both FHA and conventional loans offer low-down-payment options, but the rules regarding who qualifies for these low rates differ greatly based on your credit score and homebuyer status.

FHA Loan Down Payment Rules

With a 600+ credit score, you qualify for the FHA's 3.5% minimum down payment. This means on a $300,000 home, you would only need to bring $10,500 to the closing table.

The FHA is incredibly flexible regarding where this money comes from. 100% of your down payment can come from a documented financial gift from a family member, employer, or approved charitable organization.

Conventional Loan Down Payment Rules

Conventional loans can go as low as a 3% down payment, but this is usually reserved for first-time homebuyers who meet strict income limits and have excellent credit scores (typically 620 to 670+). If you do not meet these criteria, a conventional loan will likely require a 5% to 10% down payment.

Given a 600 credit score, securing that coveted 3% conventional down payment is highly unlikely without major compensating factors. You may have to undertake credit repair for homebuyers’ to raise your credit score by 20-50 points to qualify for a conventional loan with lower down payment. 

4. Mortgage Insurance: PMI Vs MIP

Neither an FHA nor a standard low-down-payment conventional loan requires 20% down. So, lenders require borrowers to pay for mortgage insurance. This insurance protects the lender, not the borrower, in the event of a foreclosure. 

The way this insurance is structured, billed, and canceled is one of the most significant long-term differences between an FHA and a conventional loan.

FHA Mortgage Insurance Premiums (MIP)

FHA loans require two types of Mortgage Insurance Premiums (MIP).

First, there is an Upfront Mortgage Insurance Premium (UFMIP) equal to 1.75% of the base loan amount, which is usually rolled into the loan balance.

Second, there is an annual MIP paid monthly.

The major drawback of FHA MIP is that if you put less than 10% down, this insurance cannot be canceled. It remains for the entire life of the loan, unless you eventually refinance into a conventional loan.

Conventional Private Mortgage Insurance (PMI)

Conventional loans require Private Mortgage Insurance (PMI) if you put down less than 20%.

PMI costs vary wildly based on your credit score; a lower credit score means a much higher monthly PMI payment. However, the distinct advantage of conventional PMI is that it is not permanent.

Once you build up 20% equity in your home through payments or property appreciation, you can request to have the PMI removed. This will lower your monthly payment significantly.

5. Conventional Vs. FHA: Debt-To-Income (DTI) Ratios And Loan Limits

Your Debt-to-Income (DTI) ratio is a percentage that compares your total monthly debt payments to your gross monthly income. Lenders use this metric to ensure you aren't taking on more debt than you can manage.

When comparing an FHA vs conventional loan for someone with a 600 credit score, DTI flexibility often becomes the deciding factor in how much house you can actually buy.

FHA DTI Limits And Flexibility

FHA loans are remarkably generous with DTI ratios.

While the standard maximum DTI is 43%, borrowers with compensating factors (like stable employment or cash reserves) can often get approved with a DTI as high as 50% or even 57%.

This means you can carry more existing debt (like student loans or car payments) and still qualify for a sizable mortgage.

Conventional DTI Standards

Conventional loans are much stricter.

The standard DTI maximum is typically capped at 36% to 45%. If you have a credit score on the lower end, lenders will be highly hesitant to push your DTI toward that 45% upper limit.

If you have significant outstanding debts, a conventional loan will drastically reduce the amount of mortgage you are approved for compared to an FHA loan.

6. Property Requirements And Appraisals

Getting approved for the loan is only half the battle; the house you want to buy must also be approved. Both FHA and conventional loans require a home appraisal to confirm the property's value, but the stringency of the property inspections varies. 

If you are buying a "fixer-upper," you must pay close attention to these rules.

FHA Strict Property Standards

The FHA requires that a home be "Safe, Sound, and Secure."

FHA appraisers look for specific defects: peeling lead-based paint, damaged roofs, missing handrails, or faulty HVAC systems. If the appraiser flags these issues, the seller must repair them before the loan can close. 

Also, standard FHA loans can only be used to purchase a primary residence; you cannot use them for second homes or investment properties.

Conventional Loan Property Flexibility

Conventional loan appraisals are primarily focused on the financial value of the home rather than strict health and safety standards.

While they won't finance a home with severe structural failure, they are much more lenient on minor cosmetic or functional defects.

Also, you can use these loans to finance primary residences, vacation homes, and even rental investment properties.
