Two ways to use the VA benefit
Run the numbers before you tour: pull current inventory from the Charleston Assumable List, check what your allowance buys with the BAH calculator, and keep the PCS timeline next to your underwriting calendar.
A VA loan can show up in your Charleston purchase two ways. You originate a new VA loan at today’s rate, or you assume the seller’s existing VA loan and keep that older rate. Both use the VA program. They are not the same deal.
I am a USAF veteran and a Charleston REALTOR. I work both paths. The right answer is math, not a slogan about “always assume.”
Side-by-side
Interest rate
Assume: you take the seller’s locked rate (often under 4% on this list). New VA: you get today’s VA purchase rate, which has been near the mid-6s depending on credit, points, and lender.
Cash at the table
Assume: you usually need to cover the equity gap (price minus remaining balance) with cash or a second loan. New VA: $0 down is still available for eligible buyers, so cash need is often lower up front.
Timeline
Assume: lender assumption review commonly runs 45–90 days. New VA: a clean purchase can close in a more typical 30–45 day window when the appraisal cooperates.
Seller entitlement
If a non-veteran assumes, the seller’s entitlement often stays tied to the loan. Sellers who need a full VA benefit on their next home care about this. We plan it before anyone signs.
Worked example (illustrative)
Home price $450,000. Remaining VA balance $380,000 at 2.875%. Equity gap about $70,000.
- Assume 2.875% on $380,000: principal and interest roughly $1,575/mo (30-year fixed amortization; taxes/insurance/HOA extra).
- New VA at 6.5% on $450,000 with $0 down: principal and interest roughly $2,844/mo before the funding fee is rolled in.
- Spread: about $1,270/mo on the note alone. Over five years that is real money - but only if you can fund the $70,000 gap without wrecking reserves.
Rates and fees move. Your lender runs the official numbers. This example is here so you know which questions to ask.
When assumption usually wins
- The assumed rate is at least ~1.5–2 points below a new VA quote after fees.
- You can cover the equity gap without draining emergency reserves.
- Your PCS or lease timeline can absorb a longer assumption underwrite.
- The home itself still passes VA Minimum Property Requirements and your inspection standards.
When a new VA loan is cleaner
- The equity gap is large and second-lien rates erase the monthly savings.
- You need speed (tight report date, short lease).
- The seller must restore entitlement for their next VA purchase and a non-veteran assumption would block that.
- You want $0 down and maximum cash flexibility for furniture, repairs, or dual housing.
What I do differently
I pull the assumable inventory, map it against your BAH and commute, and show both payment stacks before you write. If assumption wins, we structure the offer around lender assumption timelines. If a new VA loan wins, we still shop the list so you know what you walked away from.
