Conventional Loan and FHA Loan Together

The Short Answer: Yes, But With Conditions

Lenders allow borrowers to carry multiple mortgages simultaneously. Many homeowners do this when they refinance, take out a second mortgage, or purchase investment properties. The key requirement is that your total debt—including both loans—must fall within the lender's debt-to-income limits.

Most conventional lenders cap debt-to-income ratios at 43 to 50 percent. FHA loans allow up to 56.99 percent in some cases. If you already have a conventional loan, that payment counts toward your debt total when you apply for the FHA loan, and vice versa.

Understanding Debt-to-Income Ratios with Multiple Loans

Your debt-to-income ratio (DTI) is the percentage of your gross monthly income that goes toward debt payments. Lenders calculate DTI by dividing your total monthly debt obligations by your gross monthly income.

When you apply for a second mortgage—whether conventional or FHA—the lender includes the payment for the first mortgage in this calculation. This is called "stacking" your debt obligations.

Example: If you earn $5,000 per month and your first mortgage payment is $1,200, your DTI just from that loan is 24 percent. If you want to add an FHA loan with a $600 payment, your total DTI jumps to 36 percent ($1,800 divided by $5,000). The second lender will see this 36 percent ratio and must approve the FHA loan based on that combined debt load.

Lender Requirements for Multiple Mortgages

Different lenders have different policies about stacking mortgages. Here are the common requirements:

Debt-to-Income Caps

• Conventional loans: Most lenders approve up to 43 percent DTI with standard underwriting. Some allow 45 to 50 percent with compensating factors (like a large down payment or strong credit score).
• FHA loans: FHA approves up to 43 percent DTI as standard, but allows up to 56.99 percent with strong compensating factors.

Credit Score Requirements

When you carry multiple loans, lenders scrutinize your credit more carefully. You'll typically need a score of 620 or higher for FHA loans and 620 to 680 for conventional loans, depending on the lender's risk tolerance with stacked debt.

Loan-to-Value Ratios

If you're financing multiple properties, each loan has its own loan-to-value (LTV) requirement. A second mortgage on a cash-out refinance or home equity line of credit will have higher LTV limits (often 80 to 90 percent) than a purchase mortgage.

Cash Reserve Requirements

Some lenders require borrowers with multiple mortgages to maintain cash reserves equal to two months of payments for all properties. This shows the lender you can handle the obligation if income drops temporarily.

Primary Residence vs. Investment Property

Whether your mortgages are on the same property or different properties affects how lenders evaluate your application.

Same Property (Refinance + Second Mortgage)

If you refinance your primary residence with an FHA loan and also carry a conventional home equity line of credit, both payments count toward your DTI. The lender underwriting the new loan will verify the existing obligation and factor it into the approval decision.

Different Properties

If you own a primary residence with a conventional mortgage and want to buy an investment property with an FHA loan, the situation is different. FHA loans typically cannot be used for investment properties—they're restricted to owner-occupied primary residences, second homes, or investment condos in certain cases. However, you can stack a conventional purchase loan on an investment property with an existing conventional mortgage on your primary residence.

How to Qualify for Multiple Mortgages

Step 1: Know Your Current Debt Obligations

Pull your credit report and list all monthly debt payments: car loans, student loans, credit card minimums, and existing mortgage payments. This gives you your starting DTI.

Step 2: Calculate Your Gross Monthly Income

Include W-2 wages, self-employment income, rental income, and other verifiable sources. Lenders typically average income over two years for self-employed borrowers.

Step 3: Determine Your Target DTI

Subtract your existing DTI from the lender's maximum (43 percent for conventional, up to 56.99 percent for FHA). This is your available DTI for a new loan payment.

Step 4: Calculate Your Affordable Payment

Multiply your available DTI by your gross monthly income. For example, if you have 15 percent DTI available and earn $5,000 per month, you can afford a $750 new mortgage payment (15 percent of $5,000).

Step 5: Get Pre-Approved

Submit a pre-approval application to the lender. You'll need to disclose all existing mortgages and debts. The lender will verify everything through a credit pull and document review.

Common Scenarios: Having Both Loan Types

Scenario 1: FHA Loan First, Then Conventional

You bought your home with an FHA loan and now want to refinance with a conventional mortgage to remove mortgage insurance. This is common after building equity. The new conventional lender will check your FHA payment history and factor it into underwriting. Once you refinance, you'll no longer have the FHA loan.

Scenario 2: Conventional Loan First, Then FHA

You own a home with a conventional mortgage and want to buy a second property. Since FHA loans are for primary residences, you cannot use an FHA loan to purchase an investment property. You'd need a conventional or portfolio loan for a second investment property. However, if you're buying a new primary residence and keeping the conventional mortgage on your old home as a rental, some lenders may approve an FHA loan on the new property if your DTI allows.

Scenario 3: Simultaneous Applications

It's unusual but possible to apply for both a conventional and FHA loan at the same time if you're purchasing two properties. However, you must disclose this to both lenders. The loan applications will be contingent on each other, and both lenders will factor in the other loan's payment when evaluating your debt-to-income ratio.

Red Flags Lenders Watch

When reviewing applications for multiple mortgages, lenders look for warning signs:

• Recent late payments on existing mortgages or credit obligations
• High credit card balances relative to credit limits (above 30 percent utilization)
• New credit inquiries or recently opened accounts (suggests financial stress)
• Frequent job changes or gaps in employment history
• Unstable income or declining earnings over time
• Down payment from a gift without a gift letter
• Insufficient reserves or savings after closing

Frequently Asked Questions

Can I have an FHA loan and a conventional loan on the same house?

Yes, but only if they serve different purposes. For example, you could have an FHA mortgage and a conventional home equity line of credit (HELOC) on the same property. However, you cannot have two purchase mortgages on one house. If you refinance, the new loan replaces the old one.

Do both loans show up on my credit report and DTI calculation?

Yes. Both mortgages appear on your credit report and both payments count toward your debt-to-income ratio when you apply for additional credit. This is true whether the loans are on the same property or different properties.

What's the maximum DTI if I have both conventional and FHA loans?

If you're applying for a new conventional loan with existing FHA debt, the lender will use the conventional maximum (typically 43 to 50 percent). If you're applying for FHA with existing conventional debt, FHA allows up to 56.99 percent DTI with compensating factors. The new lender's guidelines apply to the decision.

Can I use an FHA loan to buy a rental property if I have a conventional mortgage on my primary residence?

No. FHA loans are only for owner-occupied primary residences, second homes, or certain investment condos. You cannot use an FHA loan for a pure investment property, even if you have sufficient income and DTI. You would need a conventional or portfolio loan for a rental.

Will removing an FHA loan help me qualify for a conventional loan?

Yes. If you refinance an FHA loan with a conventional mortgage, you eliminate one monthly debt obligation from your DTI calculation. This frees up room in your DTI ratio and may allow you to qualify for additional credit or larger loans in the future.

Bottom Line

You can hold both a conventional mortgage and an FHA loan simultaneously, but your total debt must fit within lender guidelines. The key factor is your debt-to-income ratio. By managing your existing debts carefully, maintaining strong credit, and having sufficient income, you can qualify for multiple mortgages.

If you're considering a second mortgage or refinance, start by calculating your DTI and speaking with a loan officer about your options. Each lender has different policies, and some are more flexible with stacked debt than others.
