The Quick Read: An FHA cash-out refinance replaces your whole mortgage, so a locked-in first mortgage goes away the day it closes. A bank loan underwritten on full documentation can be built as a second lien that leaves the first mortgage alone, though some banks also offer a full replacement. The FHA route usually fits homeowners who value flexibility on credit and need one consolidated loan. The bank route usually fits those with strong, easily verified income who want to keep the loan they already have.
“Bank full documentation” is shorthand, not a HUD or CFPB program name. Here it means a bank or portfolio loan where the lender verifies your income, assets and debts in full. In practice that is most often a home equity loan or HELOC sitting behind your first mortgage, or a conventional cash-out refinance. Keep that definition in mind, because documentation type and lien structure are two separate choices. People tend to blur them.
The Honest Answer First
If your existing first mortgage is one you would hate to lose, the structure matters more than the brand of loan. An FHA cash-out cannot sit behind your first mortgage. It pays that mortgage off. If keeping the current terms is the main goal, the bank second-lien route is the natural fit, provided your income and credit verify cleanly.
If your credit has some dings, your debt load is heavier than a bank likes, or you want a single payment instead of two, FHA is often the more forgiving lane. You give up the existing first mortgage in exchange. Whether that trade makes sense depends on how far your current terms sit from what a new loan would carry, and that is a call to make with a full Loan Estimate in hand, not from a headline.
Side-by-Side
| Factor | FHA Cash-Out Refinance | Bank Full-Doc Loan |
|---|---|---|
| Effect on your first mortgage | Replaced by one new loan | Second lien keeps it; a bank cash-out replaces it |
| Maximum leverage | 80% LTV | Set by the bank, varies by product |
| Credit floor | Decision score of 580 or higher through the network | Often higher; varies by bank |
| Mortgage insurance | Upfront 1.75% plus annual premium | Depends on product; often none on a second lien |
| Occupancy | Principal residence you have owned and occupied 12 months | Usually primary residence; some banks allow more |
| Documentation | Income, employment and debts verified | Income, assets and debts verified in full |
| Number of payments | One | Two with a second lien; one with a bank cash-out |
Every figure above on the FHA side is subject to lender guidelines and full file review, and none of it is a commitment to lend.
What “Full Documentation” Actually Means
Full documentation means the lender verifies what it relies on to qualify you. Typical items are pay records, bank or asset statements, tax records where income requires them, and a credit report. FHA cash-out is not a low-doc program. Across the wholesale programs Lendmire places FHA files with, income and employment are verified like any other full-file loan. The idea that FHA asks for less paperwork usually comes from confusing it with the FHA Streamline, which has no appraisal and a limited credit review but only refinances an existing FHA loan.
One honest caveat for the bank side: a lender generally has to verify only the income it uses to qualify you, so a bonus or side job you leave out of the application does not have to be documented. That can shorten a file for a borrower with simple traditional employment income. It can also lengthen one for a self-employed borrower whose returns understate cash flow.
When FHA Cash-Out Is the Better Fit
FHA tends to win in a handful of situations.
Your credit is middling, not pristine. The programs Lendmire places FHA loans with start at a 580 decision score. Banks offering home equity products often set a higher floor, though each sets its own.
Your debt ratios run higher than a bank likes. The base FHA ratios are 31/43 (housing and total debt to income) with no compensating factors. Documented compensating factors can stretch that to 40/50 at the top tier, and the automated finding governs most files. That flexibility is real. It is not unlimited.
You want one payment. A cash-out refinance gives one new loan and one payment. A second lien adds a payment on top of the first.
You are also trying to replace something else. If your existing first mortgage carries terms you already want out of, such as an adjustable reset coming up, replacing it is the point, not the cost.
The equity cushion is there. FHA cash-out reaches 80% of the home’s value. HUD’s Handbook 4000.1 transmittal records that the cash-out cap was set at 80 percent. Any page still quoting 85 percent is out of date. That means you must keep at least 20% equity after the loan, and the cash you can take is whatever is left between your payoff and that cap.
What FHA costs, mechanically
FHA loans carry mortgage insurance in two parts. HUD explains that most FHA programs collect an upfront premium at closing and an annual premium paid in monthly installments. The upfront premium is 1.75% of the base loan, and it is typically financed into the balance. The annual premium runs between 0.15% and 0.75% of the balance, depending on term, loan amount and LTV. On a thirty-year loan above ninety percent LTV it lasts the full term. At or below ninety percent LTV, it ends after eleven years. A cash-out at 80% LTV falls in that lower bucket.
Those are program mechanics, not a price quote. Your Loan Estimate shows what applies to your file.
Eligibility tests that catch people
FHA cash-out is for principal residences only. The home generally must have been owned and occupied for 12 months before the case number is pulled. Mortgage payment history is reviewed, and a recent late payment can matter more here than on a bank file. A borrower who had a forbearance plan should expect the lender to look at whether it was completed and how payments have gone since. Ask the lender to confirm the exact payment-history standard in the current handbook, because lenders can add their own overlays.
Inherited homes carry a special rule set. HUD’s archived refinance guidance shows an inheritance carve-out to the ownership test, and a free-and-clear home can also be cashed out.
County loan limits apply to FHA loans and change every year. Check the limit for your county before assuming a larger balance fits.
When the Bank Full-Doc Route Is the Better Fit
The bank route wins when the thing you most want to protect is the first mortgage.
You are locked in for a good reason. A CFPB consumer guide on using home equity explains the structural difference: a cash-out refinance replaces your loan, so your rate and terms change, while a home equity loan is a second mortgage with its own monthly payment. If your current terms are well below what a new loan would carry, leaving them alone can be worth the second payment.
Your income is simple and strong. A salaried borrower with clean pay records and solid credit often moves through a bank file with little friction. The bank’s pricing for strong files can beat FHA’s, since there is no mortgage insurance layer on many second-lien products.
You only need part of your equity. A smaller, targeted draw, such as a kitchen or a roof, may not justify refinancing a whole balance. A second lien sizes to the need.
You can tolerate a variable payment or a draw structure. HELOCs often carry variable payments. That suits a short project with a known payoff. It is a poor fit for someone who needs payment certainty.
The risks both routes share
Neither product is free money. The CFPB’s HELOC brochure warns that falling behind could mean losing your home, and that holds just as much for a cash-out refinance. The CFPB also notes that cash-out loans are usually repaid over 30 years, so the balance falls more slowly than on a shorter loan you may already be paying down. Restarting the clock is a cost even when the payment looks lower.
Key Terms Defined
Full documentation: a loan file where the lender verifies the income, assets and debts it relies on with third-party records.
Cash-out refinance: a new mortgage that pays off the old one and gives you part of your equity in cash.
Second lien: a loan secured by your home that sits behind your first mortgage, leaving the first untouched.
Upfront mortgage insurance premium: the one-time FHA premium, 1.75% of the base loan, usually financed.
Locked-in homeowner: an owner who holds an existing first mortgage with terms they do not want to give up.
A Simple Test for the Trade
Skip the abstract debate and walk through four questions.
1. What do you need the money for, and how much? A large, one-time need leans toward replacing the loan. A smaller or staged need leans toward a second lien.
2. How different are your current first-mortgage terms from a new loan’s? The wider the gap in your favor, the more the second-lien route protects you. Ask for a Loan Estimate on each path and compare them as complete packages, including closing costs and mortgage insurance, not by one number.
3. Would you pass a bank’s income review today? If your traditional personal-income documentation understates what you earn or your pay is irregular, a bank file may stall. FHA’s wider ratio room may carry you further. Self-employed borrowers should note that documentation type and lien structure still stay separate decisions.
4. Would doing neither be fine? Waiting, borrowing less, or paying for the project from savings is a legitimate answer. Equity is not an obligation to use.
If you work through those and the answer is still close, that is a genuine toss-up, and a side-by-side Loan Estimate comparison is the right tiebreaker.
Document Readiness
Gather these before you talk to any lender. Both paths use most of the list.
- Recent pay records and proof of employment, or business records if self-employed
- Bank and asset statements for the period requested
- Current mortgage statement and homeowners insurance
- Property tax information
- Identification and, for FHA, proof of owner occupancy history
- Documentation of any past forbearance, divorce or large credit event
A Balanced Verdict
Neither path is better in general. FHA cash-out buys flexibility on credit and ratios and gives you a single new loan, at the price of replacing your first mortgage and carrying FHA mortgage insurance. The bank full-doc route can preserve the first mortgage and often avoids mortgage insurance, at the price of a stricter income and credit review and, with a second lien, two payments.
Use the FHA cash-out refinance program when replacing the loan is acceptable or even the goal. Lean toward the bank second lien when your current loan is the asset you most want to protect and your file verifies cleanly. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Frequently Asked Questions
Can I keep my low-rate first mortgage and still use FHA?
Not through an FHA cash-out refinance, because it pays off your existing first mortgage and replaces it. If you want to keep the first loan, a separate second lien from a bank is the usual structure. Whether a particular second lender will sit behind your existing loan is that lender’s decision.
Is FHA cash-out easier because it needs less documentation?
No. FHA cash-out still verifies income, employment and debts. What FHA often offers is more room on credit and debt ratios, which is different from less paperwork. The low-documentation reputation belongs to the FHA Streamline, which only applies to existing FHA loans.
How much equity can I take out with FHA?
FHA cash-out reaches 80% of the home’s value, so you must keep at least 20% equity after closing. The home generally must have been owned and occupied for 12 months before the case number. Final amounts depend on the appraisal, your payoff and county loan limits.
Does FHA mortgage insurance ever go away on a cash-out?
Sometimes. On a thirty-year loan at or below ninety percent LTV, the annual premium ends after eleven years. Above ninety percent it lasts the term. The upfront premium of 1.75% is typically financed into the loan. Your Loan Estimate shows how it applies.
What if my income does not look right on paper?
Then the full-documentation question needs attention before you apply. Irregular or self-employed income can fail a standard review even when you earn well.
