The one idea that explains most of the differences
A loan program is just a set of rules. Who may borrow, how little they can put down, and what it costs. The key split is that three of these four are government backed and one is not.
Government backed means an agency insures or guarantees the lender against loss if the loan goes bad. That safety net is what lets a lender say yes to a buyer they would otherwise decline, and the borrower pays for it through a fee or an insurance premium. FHA, VA, and USDA all work this way. Conventional does not. It follows the rules of Fannie Mae and Freddie Mac, the two companies that buy most home loans in this country and set the guidelines lenders write to. Those guidelines also cap the size of the loan, and what happens once a price runs past the conforming limit is a different conversation entirely. No agency stands behind your specific loan, so the qualifying bar tends to be higher and pricing leans harder on your credit and your down payment.
The short answer, in four lines
Eligible for VA: price that first. For an eligible buyer with little to put down it is often very hard to beat.
In a USDA eligible area and under the income cap: price USDA next. Zero down with a lighter annual fee is a strong combination.
Thinner credit or light savings, and neither of those applies: FHA is the on ramp.
Solid credit and some down payment saved: conventional is usually the default, and at 20 percent down or more it is generally the cheapest of the four.
The rest of this article is why those lines are true, and where they stop being true.
Conventional, the default when your credit is solid
Conventional is the workhorse for buyers with decent credit and a little savings. Down payments start lower than people expect: many first time buyer programs go as low as 3 percent, and 5 percent is common otherwise. You never needed 20 percent, and where that number came from and what the real minimums are is worth knowing before you spend three more years saving for it. What 20 percent gets you is the avoidance of mortgage insurance.
Below 20 percent you pay PMI, private mortgage insurance, a monthly premium that protects the lender if you stop paying. Here is what matters more than the monthly cost: borrower paid monthly PMI ends. Federal law lets you request removal once the balance reaches 80 percent of the home's original value, and it must come off automatically at 78 percent of that original value on the loan's amortization schedule. The amortization schedule is the payment by payment table showing how the balance falls over time. Owing 78 percent of the original value is the same thing as owning 22 percent outright.
Read the words original value carefully, because this is where most articles mislead people. The right is measured against what the home was worth when you bought it, so a rising market does not trigger it. Cancelling early on appreciation is a servicer option, not a right, and your servicer, meaning the company that collects your payment each month, commonly wants the balance down to 75 percent of a fresh appraised value and wants two to five years to have passed. Ask them their policy before you pay for an appraisal. Premiums themselves are priced off your credit score and your down payment, so the same loan amount can cost two buyers very different amounts. The cancellation rules have enough moving parts that how PMI works and how you actually get it off your payment deserves its own read.
FHA, the on ramp
FHA loans are insured by the Federal Housing Administration, a government agency inside the Department of Housing and Urban Development. It is an on ramp, and plenty of people with excellent credit take it on purpose, because it is the right tool for their file that year.
The bar is lower where it usually matters. You can put 3.5 percent down with a credit score of 580 or above, and between 500 and 579, 10 percent down may be possible. Individual lenders are free to require more than the agency does. FHA also tends to be more forgiving on debt to income, meaning the share of your gross monthly income already going to debt payments, and on past credit problems. If your ratio is the thing standing in your way, how debt to income sets your loan amount explains why the program you pick can move your price.
The trade is the insurance, called MIP, short for mortgage insurance premium. It comes in two parts: an upfront premium charged as a percentage of the base loan amount, usually financed rather than paid in cash, and an annual premium divided by twelve and added to your payment. Every one of these government programs charges an upfront fee and usually an annual premium. The exact percentages are set by the agency and revised from time to time, so look up the figures in force on the day you apply rather than trusting any article, including this one.
Now the catch nobody warns buyers about. If you put less than 10 percent down on an FHA loan, that annual MIP generally stays for the life of the loan. It does not fall off at 20 percent equity, and it does not fall off at 50 percent. Equity is the share of the home's value you own outright. The only ways out are to sell or to refinance into a different loan. That is not a reason to avoid FHA, it is a reason to go in with your eyes open. The program is often chosen deliberately, with a plan to refinance into conventional once credit and equity improve, and that plan depends on a future refinance being available and making sense. Nobody can promise you that.
VA, and the question every buyer should be asked
VA loans are guaranteed by the Department of Veterans Affairs and are available to eligible veterans, active duty service members, members of the National Guard and Reserves who meet service requirements, and some surviving spouses.
For buyers who are eligible, VA financing often compares very well, because it may allow no down payment and typically carries no monthly mortgage insurance at all. On a low down payment purchase that absence can be worth a couple hundred dollars a month against the alternatives. The right program still depends on your full picture. Conventional often wins for a buyer putting 20 percent or more down, and VA financing cannot be used for an investment property or a second home.
The zero down part depends on your entitlement, which is the dollar amount of the loan the VA will guarantee on your behalf. It is the size of the government's backing, not a cap on what you may borrow. A buyer with full entitlement generally has no purchase price limit for zero down purposes, while a buyer who still has a VA loan outstanding has reduced entitlement and may need a down payment. Your loan officer can pull your Certificate of Eligibility and tell you which case you are in. The Certificate of Eligibility is the VA's own document confirming that you qualify for the program and showing how much entitlement you have available.
Instead of ongoing insurance there is a one time funding fee, set as a percentage of the loan, usually financeable, and varying with whether this is your first use and how much you put down. It is waived entirely for veterans receiving compensation for a service connected disability.
Which leads to the point I make constantly. Ask. Plenty of people do not realize a short enlistment, Guard or Reserve service, or surviving spouse status makes them eligible, and it costs nothing to find out.
USDA, the rural and suburban program people overlook
USDA loans are backed by the United States Department of Agriculture and aimed at buyers in eligible areas who fall under set income limits. Both filters surprise people, in opposite directions.
The geography is far broader than the word agriculture suggests. Eligible areas include small towns and the outer edges of metro areas nobody would call rural. Search for the USDA property eligibility map, type the address into it, and you have your answer in about a minute. Do not rule this out because you are not buying a farm.
The income limit catches more people. USDA sets maximum household incomes by area and household size, and it counts income from adults in the household even when they are not on the loan. Above the cap the program is simply unavailable.
Clear both filters and the terms are strong: zero down payment, a guarantee fee charged upfront and typically financed, and a smaller annual fee built into the payment. That annual fee is usually lighter than FHA's, and like the FHA premium on a low down payment file it generally lasts the life of the loan.
One 300,000 dollar house, five down payments, and a 5,066 dollar premium
These are example figures chosen to make the comparison visible, not quotes, not an offer, and not tied to any lender. Hold one house at 300,000 dollars and everything else steady, and the down payment moves like this. Conventional at 3 percent asks 9,000 dollars, and at 5 percent it asks 15,000 dollars. FHA at 3.5 percent asks 10,500 dollars. VA and USDA, for a buyer who clears their eligibility rules, ask nothing down at all. What any one of these programs will actually require of you depends on your own file and on the guidelines in force on the day you apply, which is why the figures above are a teaching tool rather than a menu.
Looked at that way the answer seems obvious. It is not, because cash to close is only the first line of the story.
Watch the FHA figure closely, because this is where most comparisons go wrong. The FHA buyer in this illustration wrote a 10,500 dollar check and owns about 1.8 percent of the home on day one. Here is the work behind that. The upfront premium is charged against the base loan amount, not against the purchase price. Put 10,500 dollars down on a 300,000 dollar house and the base loan is 289,500 dollars. Using an upfront premium of 1.75 percent purely as the illustrative figure, and remembering the agency revises it, 289,500 times 0.0175 is about 5,066 dollars. That gets financed on top, so the buyer starts out owing roughly 294,566 dollars against a house worth 300,000, and the sliver left over is that 1.8 percent.
Then the ongoing cost. Conventional with 9,000 down carries borrower paid monthly PMI, which ends on the schedule described earlier, a cost with a date attached. FHA with 10,500 down carries that 5,066 dollar premium plus an annual premium that, under 10 percent down, generally lasts as long as the loan. VA carries no monthly insurance and a one time fee that may be waived outright. USDA carries a small annual fee that also lasts the life of the loan.
So the lowest cash to close is not automatically the cheapest loan. Over five, seven, or ten years of ownership, an insurance premium that never goes away can easily outweigh the smaller down payment that got you in the door. Run the comparison over the time you expect to own the home, not over the closing table.
The myth: FHA is for bad credit and conventional is always better
Both halves are wrong. FHA is sometimes the right tool for a buyer with excellent credit, particularly when debt to income is tight or the file has a wrinkle conventional underwriting will not accept. And conventional is not automatically cheaper. Once you weigh the down payment difference, the PMI premium your credit earns, and how long you plan to stay, the ranking flips more often than people assume. Fit beats reputation. Ask which program is built for your situation, not which one sounds most respectable.
What to do next
Write down three facts about yourself.
One, your middle credit score. Lenders pull three and use the middle one, and if you do not know it, that is the first thing to find out. Why the middle score is the one that counts and how it prices your loan is the piece most buyers have backward.
Two, the most you can comfortably put down while still keeping a cushion in the bank after closing. Comfortably is doing real work in that sentence.
Three, whether you or your spouse served, and whether you are the surviving spouse of someone who did. Guard and Reserve service and short enlistments count more often than people expect, and eligibility is worth checking rather than assuming. While you are checking things, type the address you are shopping near into the USDA property eligibility map and see whether it comes back eligible. Both checks take minutes and both can change the picture entirely.
Those three facts point straight at your program, and they turn a loan officer's recommendation into something you can follow rather than something you have to trust. Before that conversation, see what the down payment itself is doing. Price the same house on the mortgage payment calculator at 3 percent down, at 5 percent, and at 20 percent, and watch how much of the change comes from the smaller loan and how much comes from the insurance you avoid.
For the loan officers reading this
That is the buyer's article. What follows is for the people taking the applications.
Program selection is where order takers and advisors separate. The cheapest cash to close can be the most expensive loan over five years once life of loan MIP is in the math, and most buyers cannot see that on their own. Put total cost over their expected holding period next to the down payment difference and let the comparison do the work. While you are there, calculate the FHA upfront premium against the base loan rather than the purchase price, because getting that wrong understates the balance your client walks out owing.
Teach the FHA now and refinance later path honestly. Say the risk out loud, that a future refinance depends on conditions nobody can promise, and the client will not feel misled later. And always ask about military service, of the borrower and the spouse. That question costs thirty seconds and occasionally changes somebody's entire purchase.
