How does a VA loan actually work?

The VA does not lend the money, with rare exceptions. It guarantees a portion of the loan to the lender, and that guaranty is what lets a lender offer no down payment and skip mortgage insurance entirely. The rulebook lenders follow is the VA Lenders Handbook, VA Pamphlet 26-7, and it is worth understanding a few of its specifics before assuming you know how the program works — because a good share of what circulates as "VA rules" is actually one lender's caution.

Entitlement: the number that decides everything

Your Certificate of Eligibility shows how much entitlement you have available. Full entitlement — which describes most first-time users and anyone who has fully restored a prior use — removes the loan cap entirely. You are not held to a conforming loan amount the way conventional and FHA borrowers effectively are; the lender's qualification and the appraisal set the ceiling.

If you have used the benefit before and still have an active VA loan, you are working with remaining entitlement, and that is where the math gets specific. The entitlement page walks through full, remaining and second-tier entitlement, and the second-tier scenario covers the most common version of it: buying at a new duty station while the old house still carries a VA loan.

The funding fee

The funding fee is a one-time charge, financeable into the loan, that varies by down payment and by whether it is your first use of the benefit. Veterans receiving VA disability compensation are exempt from it entirely — a detail some buyers do not realize applies to them until the lender checks. The funding fee page covers the exemption rules and what happens when a rating lands mid-process. Percentages only: the fee schedule is set by statute and the dollar amount depends on your loan, so no figure on this site should be read as your number.

Occupancy

VA loans are for primary residences. That trips people up in markets with strong rental demand, but the handbook has more flexibility than the one-line rule suggests: a spouse can satisfy occupancy during a deployment, and two-to-four-unit properties are eligible as long as you occupy one unit. What you can do with the house after you move is its own question — see renting out your VA-financed home after a PCS.

The VA appraisal and Minimum Property Requirements

The VA requires its own appraisal, performed by a VA-assigned appraiser, that checks Minimum Property Requirements — similar in spirit to FHA's health-and-safety standard. In older housing stock this can surface issues a conventional appraisal would not flag, so it belongs in your offer strategy on older homes. What happens when the appraiser flags repairs, and what the Tidewater process actually means, is on the appraisal page.

Credit, income, and where the guideline ends

The VA Lenders Handbook sets no minimum credit score — lenders do, and their overlays commonly land in the high 500s to low 600s. What the VA does require is a residual-income test: a monthly cushion left over after housing and debt obligations, scaled by family size and region. That test is arguably a better predictor of a borrower's ability to pay than debt-to-income alone, and it is a large part of why VA loans perform as well as they do as a category.

The guideline is the floor, not the ceiling. Two lenders can look at the same file and reach different conclusions because one is applying the handbook and the other is applying its own overlay on top of it. Knowing which one you are hearing is most of what a loan officer brings to the table.

What the VA sets versus what the lender sets

Where to go from here

If you are active duty, a veteran, or a surviving spouse and have not run the VA math on a purchase, do it before assuming conventional is your only option. Start with the Certificate of Eligibility — it is the document every VA file begins with — and if you are moving on orders, the PCS Home Buying Guide covers timing, BAH and orders-as-income.
