Current conventional guidelines, updated from one source.
The block below is the conforming rulebook reduced to the figures that decide a file, read from Lendmire’s single guideline source and refreshed on this page when the agencies or the wholesale overlays change: the down payment by buyer, the credit floor, the mortgage insurance threshold and its cancellation points, and the ratio maximums.
First-time buyer; 5% standard; 97% loan-to-value at the top
On a principal residence the down payment starts at 3% for a first-time buyer and 5% otherwise, the top leverage being 97% loan-to-value. Second homes and investment properties ask for more, as the leverage table shows, and the price of any leverage above 80% is mortgage insurance.
Priced on the score; no agency minimum with an automated approval
The wholesale programs behind these pages start at a 620 decision score. The agencies themselves set no minimum for an automated approval and ask for 620 on a manually underwritten fixed-rate loan and 640 on an adjustable; the score prices the loan and the insurance more than it gates them.
Required above 80% LTV; removed at 80% by request, 78% automatically
Private mortgage insurance applies above 80% loan-to-value. Fannie Mae’s 2022 figures put the annual cost in a range of 0.58%–1.86%, depending on the score and the leverage. It ends by request at 80% of the original value, automatically at 78%, and no later than the midpoint of the term.
With an automated approval; 36% to 45% on a manual file
An automated approval allows a total debt-to-income ratio up to 50%; a manually underwritten file is held to 36%, or 45% when credit score and reserves meet the agencies’ matrix. The ratio divides total housing payment plus other monthly obligations by gross income.
| Purpose | Occupancy and program | Maximum LTV |
|---|---|---|
| Purchase | One-unit principal residence, first-time buyer (fixed rate) | 97% |
| Purchase | One-unit principal residence, standard | 95% |
| Purchase | HomeReady / Home Possible (income limits apply) | 97% |
| Purchase | Two- to four-unit principal residence | 95% |
| Purchase | Second home | 90% |
| Purchase | Investment property, one unit | 85% |
| Purchase | Investment property, two to four units | 75% |
| Refinance | Limited cash-out (rate-and-term), one-unit principal residence | 95% |
| Refinance | Cash-out, one-unit principal residence | 80% |
| Refinance | Cash-out, two to four units, second home or investment | 75% |
| Combined LTV | Maximum contribution |
|---|---|
| above 90 percent | 3% of the sales price |
| 75.01 to 90 percent | 6% of the sales price |
| 75 percent or less | 9% of the sales price |
| investment property (any) | 2% of the sales price |
| Event | Waiting period |
|---|---|
| Chapter 7 or 11 bankruptcy | four years from discharge or dismissal (two years with documented extenuating circumstances) |
| Chapter 13 bankruptcy | two years from discharge; four years from dismissal (two with extenuating circumstances) |
| Multiple bankruptcy filings | five years when more than one filing within the past seven years |
| Foreclosure | seven years (three with extenuating circumstances, then limited to a principal residence or second home at 90 percent LTV, purchase or limited cash-out) |
| Deed-in-lieu, short sale or mortgage charge-off | four years (two with extenuating circumstances) |
Mortgage insurance: Fannie Mae reports that private mortgage insurance typically ranged from 0.58%–1.86% of the loan amount a year; the premium on a specific loan is priced by the insurer on the score, the leverage, and the coverage, and is never quoted here. Gifts from relatives may fund the entire down payment on a one-unit principal residence. HomeReady and Home Possible lend to 97% with income at or below 80% of the area median; HomeOne lends to the same leverage with a first-time buyer and no income limit.

What a conventional loan is — and how the file is qualified.
Four rules shape a Columbia conventional file: leverage by occupancy and buyer, credit scoring that prices rather than gates, mortgage insurance that cancels, and ratios set by the underwriting path. Each is explained below with the reason behind it.
For the program overview, see Lendmire’s conventional loan program, or the statewide guide at Conventional Loans in Tennessee; for the mortgage insurance cancellation rules, see the CFPB.
Leverage by occupancy and buyer
The down payment a Columbia buyer needs depends on three things: whether the home is a principal residence, a second home, or a rental; whether it is one unit or several; and whether the buyer counts as a first-time buyer. The snapshot table gives the answer for every combination the program allows.
Credit scores and automated underwriting
The automated system reads the score and the credit events together, and a derogatory event does not end eligibility; it starts a clock. Bankruptcies, foreclosures, short sales, and deed-in-lieu transfers each carry a waiting period in the agencies’ guides, shortened by documented extenuating circumstances, and the snapshot shows each one for a Columbia buyer.
Mortgage insurance that cancels
Twenty percent down means no mortgage insurance at all, and anything less means insurance for a while. The calculator on this page shows the Columbia payment with the estimated premium and the payment after it ends, along with the month on the amortization schedule when the request and automatic thresholds arrive.
Ratios, reserves, and the DU finding
The automated finding is the hinge of a conventional file: it reads the income, the assets, the credit, and the property, allows a total debt ratio up to the automated maximum, and names the reserves the file must show. A Columbia underwriter then verifies what the finding assumed.
A lender runs the same math on a Columbia file with one difference: the insurer’s actual premium replaces the estimate. The estimate here starts at the low end of the published range and is editable, because the real figure depends on the score and the leverage.
Where Columbia buyers borrow — and how a conforming loan fits.
These numbers are Columbia’s, not any one borrower’s: owner households, median home value, and household income from the U.S. Census Bureau. They give the scale of a typical purchase here; the score, the appraisal, and the household’s own income give the loan.
Citywide figures provide general market context, not an appraisal or an income calculation. Read the figures as ranges, not predictions. The lender appraises one home, documents one income, and lets the automated system read one credit file.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Columbia neighborhoods, distinct conventional files.
A Columbia condominium, a decades-old family house, and a second home are three different conventional files: different project reviews, different leverage, different reserves. The six submarkets below show the range.
Multi-unit conversions
Columbia’s converted two- and three-unit homes are conventional purchases at multi-unit leverage with the buyer in one unit, other-unit rent counted per agency rules, and part of the down payment from the buyer’s own funds over the threshold. Columbia is home to about 45K people.
Newer subdivisions on the bypass
The newer Columbia subdivisions out by the bypass appraise cleanly, and the system often offers value acceptance; the question is whether the ratio carries the higher price with the insurance added. Roughly 11,427 Columbia households own their homes on the latest Census estimate — 63% of all households, the pool a conventional purchase joins.
Rural-edge and acreage properties
Homes on larger lots around Columbia are conventional purchases when the use is residential; agricultural use puts the property outside the program, and the appraisal values the house and the land on comparable sales. About 37% of Columbia’s households rent — roughly 6,612 renter households on the latest Census estimate.
Everyday values and the first-time minimum
At Columbia’s price levels the conventional structure is at its most comfortable: a small down payment that may be a gift, a premium that ends on schedule, and a payment that typically leaves room under the ratio on a local income. The median owner-occupied home value in Columbia runs near $308,700 on the latest Census estimate.
In-town neighborhoods
In Columbia’s older neighborhoods the value report decides more than the condition report. A buyer at the first-time-buyer minimum pays insurance for a while; a buyer at twenty percent pays none. On a one-unit principal residence at Columbia’s median value, the first-time buyer’s minimum down payment comes to about $9,300 and the standard minimum to about $15,400 — before closing costs, and before the mortgage insurance that comes with either; a second home, a multi-unit home, or a rental starts higher, as the leverage table shows.
Manufactured homes
The agencies will buy a loan on a Columbia manufactured home that meets their requirements, confirmed by the appraisal; the leverage is set for the property type, and the insurance follows the leverage as it would on any conventional loan. Median household income in Columbia sits near $63,719 on the latest Census estimate.
What the program accepts is the same everywhere in Columbia: houses, warrantable condominiums, planned developments, manufactured homes that meet the agencies’ rules, two- to four-unit homes, second homes, and investment property, each at its own leverage. What it declines is the non-warrantable project and the loan above the conforming limit, which belong to other programs.
Four ways Columbia buyers put a conforming loan to work.
Columbia borrowers use conforming loans for reasons that repeat, from the first purchase at the first-time-buyer minimum to the refinance on a home with equity, and the cards below take up the ones that come up most often.
Buy a second home
A second home in Columbia is a conventional file with its own leverage and reserve rules: more down than a principal residence, the payment on the existing home counted in the ratio, and a property the owner occupies part of the year rather than rents full time.
Refinance or take cash out
A Columbia owner can refinance a conventional loan two ways: a limited cash-out refinance to the rate-and-term leverage in the snapshot, or a cash-out refinance to the lower cash-out leverage after the seasoning period, on a principal residence, second home, or rental at each occupancy’s own limit.
Buy a condominium in a warrantable project
A Columbia condominium is a conventional purchase when the project passes the agencies’ review: owner-occupancy mix, budget and reserves, litigation, commercial space, and ownership concentration. The dues enter the ratio, and the leverage follows the occupancy as it would on a house.
Buy an investment property
A Columbia investor buying one to four units on a conventional loan puts down what the leverage table shows for investment property, documents agency-allowed rent toward qualifying, and holds reserves the finding requires per financed property. It is an individual agency loan under investment-property rules, not an investor DSCR loan.
Estimate the payment on a Columbia price before requesting a quote.
The program’s own math on your Columbia inputs: price less the down payment, amortized at the benchmark, with the insurance estimate added while the leverage is above the threshold and the escrows added throughout. The actual rate, premium, payment, and costs come in writing from a licensed loan officer.
Columbia conventional payment estimate
The defaults are a Columbia starting point, not your purchase: put in the real price, the real down payment, and the real escrows.
Editable benchmark: 7.28% as of October 1, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $310,000 price near Columbia’s median owner-occupied home value, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, property taxes and insurance estimated for Tennessee (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
Same buyer, three very different closings.
The score, the down payment available, VA eligibility, and the expected length of the loan decide which program wins. Here are the three, one next to the other.
Conventional, FHA, or VA.
This program offers a low down payment for first-time buyers, insurance set by the score and removed once the balance falls below the threshold, and no upfront premium on the monthly structure. Of the three programs compared here, it alone finances second homes and investment property. The cost is a credit standard that prices a weak score heavily.
FHA asks for a small minimum investment that a gift can cover, accepts a forgiving decision score, and charges an upfront premium plus an annual premium that lasts for the term at full leverage. For a Columbia buyer with a modest score it usually wins; for a strong score the conventional premium is smaller and temporary. See Lendmire’s FHA loan program.
VA beats conventional on the principal residence for nearly every eligible borrower; conventional beats VA on everything VA does not touch: second homes, rentals, and buyers without the certificate. The two often sit side by side in one Columbia household. See Lendmire’s VA loan program.
Choose by profile: a strong score and any down payment point to conventional; a modest score and a small down payment point to FHA; eligibility with full entitlement points to VA. A Columbia loan officer runs all three on the same numbers before recommending one. Above the conforming limit, see the jumbo loan program.
What to prepare for a Columbia scenario review.
Gather these before a Columbia review: the ordinary mortgage documents, plus the pieces that settle the first-time-buyer question and the occupancy.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the automated underwriting finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
When a Columbia conventional file surprises someone, the cause is usually one of these: a premium higher than expected, a score that priced differently than hoped, an appraisal under the price, a project that failed review, or a loan amount over the conforming limit.
Use these checks to keep the Columbia file clean and fundable.
Three things to settle before a Columbia review: how the mortgage insurance will be structured and when it ends, where the decision score lands and what it prices, and whether the property has any agency question attached.
- Plan the insurance: the premium is priced on the score and the leverage inside the published range.
- Confirm the score: the score sets the loan-level adjustments and the insurance premium more than it gates the loan.
- Mind the appraisal: a short value is paid in cash, renegotiated, or released under the contingency.
Mortgage insurance: how much, and until when
The premium on a Columbia loan can be paid monthly, paid by the lender in exchange for a different price, paid as a single premium at closing, or split. The monthly structure cancels under the federal rules, and the others are set by the lender. The calculator shows the monthly structure and the month the thresholds arrive on scheduled payments.
The score sets the cost
The decision score comes from the lender’s report, and with multiple borrowers the automated system uses the average of the median scores. On a Columbia conventional file the score rarely ends eligibility, but it sets the loan-level adjustments and insurance premium, so a few points can change monthly cost.
The appraisal and value acceptance
A conventional appraisal values the Columbia home and reports on condition without a HUD or VA property standard; the home must be safe, sound, and marketable. The automated system sometimes offers value acceptance or an appraisal waiver, in which case no appraisal is ordered and the file closes on the system’s valuation.
Occupancy and its leverage
Each occupancy has its own leverage limit and loan-level adjustments: a principal residence occupied within sixty days of closing reaches the top of the table, a second home is lower, an investment property lower still. A Columbia buyer who states one occupancy and uses another has misrepresented the loan.
Warrantable or not
Project review is the one property question that can take a Columbia condominium out of the program entirely. The lender collects the association’s questionnaire, budget, and insurance before the appraisal, and a buyer under contract should ask early how the project reads.
From a Columbia pre-approval to keys in hand.
Underneath, the Columbia process is any mortgage process; what makes it conventional is the automated finding, the project review where it applies, the leverage by occupancy, and the insurance threshold. Each step below says what happens and what the buyer does.
Pre-approval
The first conversation settles the shape: whether the buyer counts as a first-time buyer, what leverage the occupancy allows, how much insurance the down payment carries, and whether conventional is the right program next to FHA and VA for the Columbia purchase.
Contract and appraisal
The Columbia contract sets the price and the contributions; the appraisal, or the system’s value acceptance, sets the value. Both feed the loan amount, and the lender confirms the project review and the conforming limit before underwriting begins.
Underwriting
Underwriting on a Columbia conventional file verifies the finding: the documents behind income and assets, the source of the down payment, the project review, and the insurance commitment for the leverage. Conditions are cleared and the approval is issued with its terms.
Closing
The Columbia closing applies the program’s structure: the insurance premium in the payment while it applies, the escrow account, and no upfront premium on the monthly structure. The buyer moves in within sixty days on a principal residence, and the servicer tracks the balance toward the cancellation thresholds.
A brokerage that prices the whole market.
Lendmire never lends. It reads a Columbia file against conventional, FHA, and VA, matches the program to the profile, and keeps the premium, the cost tier, and the conforming limit in front of the buyer before anything is signed.
Several programs, one set of numbers
The comparison printed on this page is run for real on every Columbia file: conventional with the insurer’s actual premium beside FHA with its premiums beside VA where eligibility exists, and the written terms follow from it.
The insurance explained before the offer
The insurance is the program’s cost and the cancellation rules are its advantage, and Lendmire explains both first rather than last: how much the premium is, which structure fits, and when it ends for a Columbia buyer at the price in hand.
Licensed, consumer-purpose, in writing
What this page shows are the agencies’ parameters and the wholesale overlays; what a specific Columbia loan gets is a written set of terms from a licensed loan officer after the review. Lendmire is a broker, never the lender.

Columbia conventional loan FAQs
The questions below come up on nearly every Columbia conventional conversation. The answers are general; the figures in the snapshot above are the program’s current parameters.
What is a conventional loan, and who is it for?
The general-purpose mortgage: conforming to the agencies’ guides, priced on the credit score, insured privately only while the leverage is above the threshold. It is the program most Columbia buyers compare first and, of the three compared here, the one that reaches a second home or an investment property.
How much do I need to put down on a conventional loan in Columbia?
It depends on who is buying and how the home will be used. A first-time buyer starts at the lowest figure in the snapshot, a repeat buyer slightly higher, and a Columbia second home or rental higher still. Twenty percent down removes mortgage insurance entirely.
What credit score do I need for a conventional loan?
The practical answer is the floor in the snapshot, and the useful answer is that every tier above it lowers the cost. A Columbia buyer with a modest score should run FHA beside conventional, because FHA prices its insurance by schedule rather than by score.
How does private mortgage insurance work, and when does it end?
Three dates matter: the month the balance reaches the request threshold, when the borrower can ask the servicer to drop the premium with a good payment history; the month it reaches the termination threshold, when the servicer must drop it; and the midpoint of the term, the final backstop. Twenty percent down means none of this applies.
What is the conforming loan limit in Columbia?
Ask a loan officer for the county’s current limit; it changes yearly and by unit count. Above it, a Columbia purchase is still possible with a larger down payment on a conforming loan or on a jumbo loan.
What debt-to-income ratio does a conventional loan allow?
It depends on the underwriting path. The snapshot shows the automated maximum and the manual pair; enter income in the calculator to see where a Columbia scenario lands against the automated figure.
Can I get a conventional loan after a bankruptcy or foreclosure?
Yes, once the waiting period in the snapshot table has run: each bankruptcy chapter, a foreclosure, a deed-in-lieu, and a short sale carry their own period, measured from discharge, dismissal, or the completion of the event, and several are shortened by documented extenuating circumstances. The periods are longer than FHA’s or VA’s.
Can the seller pay my closing costs on a conventional loan?
The seller may give up to the share of the price in the snapshot table for the combined loan-to-value. Anything above it lowers the price used to size the loan, and the seller may not fund the down payment.
Can the down payment be a gift?
It can, from an acceptable donor, for all of it on a one-unit principal residence; the donor must be a relative or similar, the letter must state no repayment is expected, and the transfer must be documented. Gifts may also fund closing costs and reserves.
What does the appraisal check on a conventional loan?
Value against the contract price, and condition against the lender’s standard of safe, sound, and marketable. Older Columbia homes draw condition notes more often; most are settled before closing.
A Columbia conventional loan sized to the price, the score, and the leverage.
A Columbia conventional purchase starts with three questions: the score, the down payment, and the occupancy. Lendmire answers them, prices the programs, and writes up the one that fits.
