Current conventional guidelines, updated from one source.
Four cards and three tables carry every figure a conventional file turns on, drawn from one source built on the agencies’ published guides: down payment, credit, mortgage insurance, ratios, then the leverage by occupancy, the seller-contribution caps, and the waiting periods after a credit event.
First-time buyer; 5% standard; 97% loan-to-value at the top
3% down is the first-time buyer’s entry point and 5% the standard one, both on a one-unit principal residence; second homes, two- to four-unit homes, and investment properties carry their own leverage limits, listed in the table below.
Priced on the score; no agency minimum with an automated approval
A 620 decision score opens the program on the wholesale side; the agencies set no minimum for an automated approval and 620 to 640 for manual underwriting by loan type. The strongest effect of the score is on cost, through loan-level adjustments and the mortgage insurance premium.
Required above 80% LTV; removed at 80% by request, 78% automatically
The insurance line in a conventional payment is a bridge, not a fixture: required above 80% loan-to-value, cancellable at 80% on request and 78% by law, and priced by the insurer on the score inside Fannie Mae’s published 0.58%–1.86% range. Twenty percent down skips it entirely.
With an automated approval; 36% to 45% on a manual file
Total debt against gross income, up to 50% on an automated approval and 36% to 45% on a manual file. The housing payment counted includes the mortgage insurance while it applies, which is why cancellation changes the ratio as well as the payment.
| 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 Chattanooga conventional file: leverage by occupancy and buyer, credit scoring that prices rather than gates, mortgage insurance that cancels, and ratios set by the automated finding. 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
Who the buyer is matters as much as what the home is. A first-time buyer, meaning no ownership interest in a home for three years, qualifies for the smallest down payment on a principal residence; a repeat buyer starts a little higher; and HomeReady, Home Possible, and HomeOne open the top leverage to buyers who meet their conditions.
Credit scores and automated underwriting
What the score does on a Chattanooga conventional file is set the cost. A lower score raises the loan-level adjustments and the insurance premium; a higher score lowers both. Manual underwriting, used when the automated system cannot approve the file, carries its own minimum score and tighter ratios.
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 Chattanooga 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 Chattanooga underwriter then verifies what the finding assumed.
A lender runs the same math on a Chattanooga 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 Chattanooga buyers borrow — and how a conforming loan fits.
Conventional loans are sized against a local market, and these are Chattanooga’s numbers from the U.S. Census Bureau: how many households own, what a typical home is worth, and what households earn. Together they set the scale of a typical down payment, loan, and insurance premium.
Read the figures as backdrop. Higher values mean a larger down payment in dollars and a larger insurance premium; lower values mean a payment that leaves more room under the ratio ceiling. The percentages do not move; what they amount to does.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct Chattanooga neighborhoods, distinct conventional files.
No single conventional file describes Chattanooga. The neighborhoods below differ in housing stock, price, occupancy mix, and the appraisal questions they raise, and each one shapes how a conforming loan is put together.
Two-to-four-unit homes
Owner occupancy of one unit sets the leverage on a Chattanooga multi-unit conventional loan; without it, the property is an investment purchase at the lower investment leverage. The appraisal reads every unit and the rents. Roughly 41,437 Chattanooga households own their homes on the latest Census estimate — 52% of all households, the pool a conventional purchase joins.
Established close-in neighborhoods
An older Chattanooga house is a routine conventional purchase; the appraisal is lighter on condition than a government appraisal, which is one reason buyers of older homes often choose this program. The value against the contract price is the usual question. Median household income in Chattanooga sits near $64,523 on the latest Census estimate.
Higher-value homes
A high-value Chattanooga purchase can still be a conforming loan when the loan amount fits under the county limit, and a high-cost county’s higher range extends that reach; above it, the jumbo program takes the file with its own leverage and reserves. About 48% of Chattanooga’s households rent — roughly 37,647 renter households on the latest Census estimate.
Newer infill and recent construction
New rows and recent infill in Chattanooga tend to appraise cleanly, which moves the question to the loan amount: a contract near the conforming limit is confirmed against the county figure before the offer, and a loan above it needs a larger down payment or the jumbo program. Chattanooga counts a population near 186K within the Chattanooga, TN-GA area.
Investor and second-home purchases
Chattanooga rentals and pied-à-terre purchases run on conventional loans because FHA and VA finance principal residences only: the investment and second-home leverage in the snapshot, reserves for each financed property, and adjustments for the occupancy. The median owner-occupied home value in Chattanooga runs near $283,200 on the latest Census estimate.
Condominiums and townhomes
Townhomes in Chattanooga finance like houses when they are fee simple and like condominiums when they are organized as one; the lender settles which before the appraisal, and the leverage follows the occupancy either way. On a home at Chattanooga’s median value, the first-time buyer’s minimum down payment comes to about $8,500 and the standard minimum to about $14,200 — before closing costs, and before the mortgage insurance that comes with either.
Each Chattanooga submarket has its own property story, and the appraisal and the project review are where that story is told. The leverage limits, the cancellation rules, and the automated finding are the constants.
Four ways Chattanooga buyers put a conforming loan to work.
Because the agencies buy loans on principal residences, second homes, and investment property alike, the conventional loan is a program a Chattanooga household can use for every home it owns. Four examples follow.
Buy a condominium in a warrantable project
The condominium file adds the project review to the house file. Once a Chattanooga project clears it, the first-time buyer’s minimum, the insurance rules, and the ratio ceiling are exactly what they would be on a single-family home.
Buy with twenty percent down and no insurance
The move-up Chattanooga buyer selling one home and bringing twenty percent to the next usually lands here: no mortgage insurance, the strongest cost tier the score earns, and a loan the automated system approves on the equity brought forward.
Buy a first home at the first-time-buyer minimum
For a Chattanooga first purchase, the conventional route pairs the agencies’ lowest down payment with insurance that cancels and no upfront premium; the file is qualified on the score, the ratio, the reserves, and the automated finding, and a family gift may fund the whole down payment.
Buy an investment property
The rental purchase is inside the conventional program at a lower leverage than a principal residence: a Chattanooga buyer uses the agencies’ rules for counting rental income, shows reserves for every property financed, and accepts loan-level adjustments that reflect the occupancy.
Estimate the payment on a Chattanooga price before requesting a quote.
Before you ask for a quote, size the payment yourself: the Chattanooga price, the down payment, the term, the benchmark rate, the insurance estimate, and the escrows go in, and the thresholds and the ratio ceiling come from the same guideline source as the block above. The result is an estimate, the rate is a published market average, and the insurance figure is an editable estimate inside Fannie Mae’s published range.

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.

Same buyer, three very different closings.
Choosing among conventional, FHA, and VA in Chattanooga is really choosing an insurance structure and a credit standard at the same time. Each is laid out below with the buyer it fits.
Conventional, FHA, or VA.
The program’s strengths are the cancellable insurance, the breadth of occupancies, and a cost structure that rewards a strong score; its weakness is the same structure applied to a weak one. A Chattanooga buyer with a strong score usually pays less each month here than on FHA.
Where conventional prices the score, FHA prices by schedule. FHA fits the buyer whose score would be priced heavily on a conventional loan, or who needs the ratio ladder’s room; it rarely wins for a Chattanooga buyer with strong credit and a down payment above the minimum. 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 Chattanooga 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 Chattanooga 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 Chattanooga scenario review.
The paperwork is the standard mortgage set, with the automated finding deciding how much of it the file actually needs; here is what a Chattanooga scenario review typically draws on.
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.
What moves a Chattanooga file most often: the insurance and its cancellation, the score and the cost it sets, the appraisal, the condominium review, the conforming limit, the ratio and the reserves, the occupancy rule, and the seasoning after a credit event.
Use these checks to keep the Chattanooga file clean and fundable.
Three things to settle before a Chattanooga 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: it cancels on request at the request threshold and automatically at the termination threshold.
- Confirm the score: the score sets the loan-level adjustments and the insurance premium more than it gates the loan.
- Check the limit: ask a loan officer for the current figure in the county.
Mortgage insurance: how much, and until when
Cancellation on request needs a good payment history, no subordinate liens, and no decline in value; automatic termination needs only that the loan be current. A Chattanooga owner whose home has gained value may also ask the servicer to recognize the current value under its own rules, which is a servicer decision rather than a program right.
The score sets the cost
The decision score is read from the lender’s report, and with more than one borrower the automated system uses the average of the median scores. On a Chattanooga conventional file the score rarely ends eligibility, but it sets the loan-level adjustments and the insurance premium, so a difference of a few points can change the monthly cost.
The conforming limit
Conforming loans are capped by county and by unit count, with higher limits in high-cost areas, and the figures are reset each year by the FHFA. A Chattanooga purchase whose loan would run above the limit either brings a larger down payment to fit under it or moves to the jumbo program; a Lendmire loan officer confirms the current limit for the county.
Occupancy and its leverage
Each occupancy has its own leverage limit and its own loan-level adjustments: a principal residence occupied within sixty days of closing reaches the top of the table, a second home sits lower, and an investment property lower still. A Chattanooga buyer who states one occupancy and uses another has misrepresented the loan.
Warrantable or not
A Chattanooga condominium is a conventional purchase when the project passes the agencies’ review: owner-occupancy mix, budget and reserves, litigation, commercial space, single-entity ownership, and insurance. A project that fails is non-warrantable and outside the conforming program; a portfolio lender may still finance it on other terms.
From a Chattanooga pre-approval to keys in hand.
Underneath, the Chattanooga 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
Start with the score, the income, the down payment, and the occupancy. A Lendmire loan officer runs the automated system, confirms the leverage and the insurance for the down payment chosen, checks the loan against the conforming limit, compares the structure with FHA and VA on the same numbers, and provides the terms in writing.
Contract and appraisal
With the contract signed, the lender orders the appraisal, or accepts the value the automated system offers where a waiver applies. Seller contributions are checked against the cap for the leverage, and a condominium’s project documents are collected for review before the file moves on.
Underwriting
The underwriter verifies what the automated finding assumed: the income, the assets and reserves, the credit and any seasoning, the occupancy, and the property. A manual file follows the lower ratio pair instead. Conditions are issued, documented, and cleared before the approval is final.
Closing
The Chattanooga closing applies the program’s structure: the insurance premium in the payment while it applies, the escrow account, and no upfront premium. 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.
The case for a brokerage on a conventional loan is candor with numbers: the same file priced across programs, the insurance premium and its cancellation month stated outright, the leverage checked against the occupancy, and the terms in writing.
Several programs, one set of numbers
A lender with one rate sheet sells that sheet; a brokerage with several can say which fits. For a Chattanooga buyer with a strong score that is usually a conventional loan on the program whose cost is lowest for that file; for a modest score it may be FHA, and the arithmetic decides.
The insurance explained before the offer
The premium and its exit are decided by the leverage and the score, and a buyer should know both before signing a contract. Lendmire states the structure for the Chattanooga purchase, shows the payment before and after cancellation, and explains the request and automatic thresholds.
Licensed, consumer-purpose, in writing
Lendmire carries the license for the state the Chattanooga home is in, delivers the disclosures a consumer mortgage requires, and commits the terms to paper. The program figures on this page are read from one guideline source built on the agencies’ published guides.

Chattanooga conventional loan FAQs
Plain answers to the questions Chattanooga buyers ask most about conventional loans, in the order they usually ask them.
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 Chattanooga 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 Chattanooga?
A small share of the price for a first-time buyer, a little more for a repeat buyer, and twenty percent to skip the insurance. On a Chattanooga home at the median value the market section shows what the minimums come to in dollars.
What credit score do I need for a conventional loan?
A conventional loan prices credit rather than simply gating it. The practical floor is the wholesale overlay in the snapshot; the agencies’ own minimum applies only to manual underwriting. Above the floor, the premium and the loan-level adjustments fall as the score rises.
How does private mortgage insurance work, and when does it end?
The premium is a percentage of the loan a year, divided into the monthly payment, and it is set by the insurer on the score and the leverage rather than by a government schedule. It cancels: by request at the request threshold, automatically at the termination threshold, and no later than the midpoint of the term.
What is the conforming loan limit in Chattanooga?
There is a county limit, revised annually, and some counties carry a high-balance range above the standard figure. The loan officer confirms the current limit at pre-approval; above it, the jumbo program takes the file.
How does a conventional refinance work?
A conventional refinance has its own rows in the leverage table, below the purchase rows. The limited cash-out version changes the loan’s terms; the cash-out version borrows against equity and generally needs six months of ownership first.
What does the appraisal check on a conventional loan?
It confirms what the home is worth and that it is acceptable collateral. Waivers and value acceptance, where the system offers them, replace the appraisal and its fee; otherwise a licensed appraiser values the home on comparable sales.
Can I take cash out with a conventional refinance?
Yes, at the leverage in the snapshot for the occupancy, after the seasoning period. The cash-out loan carries its own loan-level adjustments, and the loan-to-value decides whether mortgage insurance applies to the new loan.
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.
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.
Buy in Chattanooga with a low down payment and insurance that ends.
A Chattanooga 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.
