Columbia, SC DSCR Rental Loan Deep Dive: Fort Jackson, USC, and the Midlands Market

Columbia sits at the center of South Carolina's Midlands region, and its rental demand runs on three engines that rarely slow down together: the University of South Carolina, Fort Jackson, and a state government workforce that anchors Richland and Lexington counties in good years and bad. For DSCR investors, that diversified demand base is the pitch. The underwriting reality is more specific, and it starts with a property tax rule that catches a lot of out-of-state buyers off guard.

The 6% assessment ratio that changes your PITIA

South Carolina assesses owner-occupied primary residences at 4% of fair market value for property tax purposes, but non-owner-occupied rentals — including every property you'll finance with a DSCR loan — get assessed at 6%. That's a 50% jump in the assessed base before millage rates even enter the picture. In Richland County, combined millage typically lands in the 300-400 mill range depending on the specific taxing district, which works out to an effective rate on a rental property of roughly 1.0-1.3% of fair market value annually, versus 0.6-0.8% you'd see on an owner-occupied home in the same neighborhood. On a $260,000 purchase, that's the difference between a $1,700 and a $3,000 annual tax bill, and it lands directly in your PITIA denominator. Skip this line item in your pro forma and your DSCR will come in lower than expected at closing, the same trap we flag in our broader DSCR ratio walkthrough.

Fort Jackson and the PCS rental cycle

Fort Jackson trains roughly half of all soldiers entering the Army each year, and that volume — plus the permanent-party staff, drill sergeants, and instructors stationed there — creates a rental base that turns over on a predictable military calendar rather than a seasonal one. PCS (permanent change of station) season runs heaviest May through August, which means listings near the post in Southeast Richland County and along the Fort Jackson Boulevard corridor lease fastest in early summer and can sit longer in the dead of winter. Lenders don't underwrite around military seasonality directly, but appraisers pulling 1007 rent comps in these submarkets should be sourcing from year-round lease data, not a single summer listing — worth confirming before you rely on the appraised rent to hit your coverage target.

USC and the Five Points rental economy

The University of South Carolina enrolls around 35,000 students, and the Five Points and Rosewood neighborhoods immediately south and east of campus run almost entirely on student and young-professional leases. These properties often carry higher gross rents per square foot than family rentals elsewhere in Columbia, but expect more wear, shorter average tenancy, and lenders who may want to see a signed lease or trailing rent roll rather than relying solely on the 1007 for a property with a clear student-rental use case. If you're assembling a small portfolio here, the same underwriting logic that applies to 2-4 unit properties is worth reviewing, since a lot of the Five Points inventory is older duplexes and triplexes rather than single-family stock.

Submarket breakdown

Columbia isn't one market. Northeast Richland and Lexington County's Chapin/Lake Murray corridor skew toward newer construction, owner-quality finishes, and tenants who are state employees or corporate relocations — lower cap rate, more stable coverage. Forest Acres and Shandon are established, walkable, higher-price-point neighborhoods with strong long-term tenant demand but thinner cash flow margins. Southeast Richland near Fort Jackson trades at a discount to the rest of the metro and produces some of the highest gross rent-to-price ratios in the city, which is where DSCR math tends to pencil best on a straight coverage basis — provided you've built the 6% tax assessment into the number rather than the 4% figure Zillow or a listing agent might quote you.

Running the numbers on a Southeast Richland purchase

Take a $215,000 duplex near Fort Jackson, financed at 75% LTV with a $161,250 loan at 8.125% on a 30-year fixed. Principal and interest runs about $1,196. Add property tax at the 6% investment assessment (roughly $210/month on this purchase price and a representative Richland millage rate), insurance around $140/month, and no HOA, and PITIA lands near $1,546. Two units renting at $1,050 and $975 combine for $2,025 in gross monthly rent, producing a DSCR of 1.31 — comfortably above the 1.20-1.25 minimum most DSCR lenders want for their best pricing tier. Run that same tax line at the owner-occupied 4% rate by mistake and you'd underestimate PITIA by roughly $70/month, enough to overstate your DSCR and get a nasty surprise at closing disclosure.

Rate, LTV, and lender fit for the Midlands

Expect a 7.5-9.25% rate range on a 30-year fixed DSCR loan in the Columbia market as of mid-2026, with pricing toward the lower end reserved for 700+ FICO borrowers with DSCR above 1.20 and LTV at or below 70%. Purchase LTV typically caps at 75-80%, cash-out refinances closer to 70-75%. Because Columbia is a secondary metro rather than a top-20 MSA, not every lender in the DSCR lender directory prices it identically — some non-QM shops apply a metro-tier adjustment to smaller markets, so it's worth quoting two or three lenders rather than assuming the rate you'd get in Charlotte or Atlanta carries over. South Carolina's broader lending environment, including its judicial foreclosure timeline and landlord-tenant statutes, is covered in our South Carolina DSCR overview.

How Columbia compares to the rest of the Palmetto State

Investors often cross-shop Columbia against South Carolina's other DSCR-active metros. Spartanburg, roughly ninety minutes northwest along I-26, offers a similar rent-to-price profile but leans more on manufacturing and logistics employment than institutional demand. Greenville, the state's fastest-appreciating metro, trades at a premium to both — worth a look at the Greenville market page if you're weighing entry points across the Upstate versus the Midlands. Columbia's advantage is diversification: university, military, and state government don't move in the same cycle, which is exactly the kind of demand stability that keeps a DSCR coverage ratio from swinging hard in a downturn.

Reserve and documentation expectations

Most lenders active in Columbia will want two to six months of PITIA in reserves depending on your credit tier and the property's DSCR, with the higher end applying to sub-1.0 or thin-coverage deals. Run any Southeast Richland or Five Points purchase through a DSCR calculator using the 6% investment assessment ratio, not the owner-occupied number a listing might show, before you make an offer — that single adjustment is the most common reason Columbia deals come in under projection at closing.
