Oklahoma conventional mortgage: limits, down payment math and the state rules

Oklahoma buyers using a conventional loan face the same three questions everywhere — how much down, what it costs each month, when mortgage insurance ends — with answers that depend on the state’s $210,000 median and 0.89% effective property tax. This page works them out, then covers the Oklahoma rules that touch the loan.

Conforming or jumbo in Oklahoma?

$832,750 is the ceiling on a conforming one-unit loan in Oklahoma for 2026. On the $210,000 median, a 20% down loan of $168,000 is 20% of the limit, comfortably conforming. Above the limit the loan is jumbo: typically a higher score, more reserves, a full appraisal and no automated-underwriting shortcuts. Every Oklahoma county is in the table below; see conforming loan limits and jumbo loans.

2026 conforming loan limits by county in Oklahoma

For 2026 the FHFA county list shows a single tier in Oklahoma: all 77 counties at the $832,750 baseline for one unit, $1,066,250 for two units, $1,288,800 for three and $1,601,750 for four. Above those figures a loan is jumbo, whatever the county.

Down payment and monthly payment, four ways

Worked at an illustrative 6.5% over 30 years on the $210,000 median. PMI uses order-of-magnitude annual rates by down payment; tax uses Oklahoma’s approximate 0.89% effective rate. Your county, score and insurer will move every column.

The 3% row assumes a program such as HomeReady or Home Possible; income limits apply. Compare with FHA at 3.5% down on the FHA vs conventional guide.

When PMI ends in Oklahoma

Under the Homeowners Protection Act, the 80% request point and the 78% automatic point are measured against the original value. The scheduled payments on the $199,500 5% down loan reach 80% after about 10 years and 4 months, on the $189,000 10% down loan after about 7 years and 11 months. Fannie Mae and Freddie Mac servicers also cancel on current value — typically 75% LTV after two years or 80% after five — which in a rising Oklahoma market can come sooner.

The Oklahoma closing: costs and who runs it

Oklahoma is an abstract state: an abstract company brings the abstract of title up to date, an attorney renders a title opinion on it, and a title company issues the policy and conducts the closing. The attorney’s role is the opinion, not the closing itself, which an escrow closer at the title company handles; Oklahoma is wet-funding. Abstract continuation and examination fees make Oklahoma title costs higher than a simple search, and the custom is for the seller to pay for the abstract update.

Oklahoma levies a mortgage tax under 68 O.S. § 1904 on the note, graduated by term and topping out at 10 cents per $100 of principal for mortgages of five years or longer, plus a small certification fee, and the county treasurer must stamp the mortgage as paid before the clerk will record it; the borrower customarily pays it. The documentary stamp tax of 75 cents per $500 falls on the deed and is paid by the seller. The mortgage tax is due again on a refinance. Oklahoma’s documentary stamp tax is $0.75 per $500 (0.15%), paid by the seller; there is no mortgage tax beyond a small mortgage registration fee.

Oklahoma buyer closing costs typically total 2% to 3% of a low price; abstract and title opinion practices persist in parts of the state alongside title insurance.

Prepayment, spouses and homestead in Oklahoma

Prepayment. Oklahoma’s Uniform Consumer Credit Code, title 14A, gives a consumer the right to prepay in full at any time, but first-lien residential mortgages are largely outside its rate and term limits, so a penalty on such a loan is governed by the note and by federal qualified-mortgage rules rather than a state ban. On a conforming loan the question is moot — the agencies do not accept penalties — but check a portfolio or jumbo note.

Spouses and title. Oklahoma is a separate-property state, so the non-borrowing spouse’s debts do not count in underwriting.

Homestead. Oklahoma has an unlimited-value homestead: article XII of the state constitution and 31 O.S. § 1 and § 2 protect a home of any value on up to one acre in town or 160 rural acres from general creditors, subject only to mortgages, taxes and liens for work or materials.

The complete state layer — licensing, predatory-lending limits, disclosures, foreclosure — is on mortgage laws in Oklahoma.

Frequently asked questions

What is the conforming loan limit in Oklahoma for 2026?

For 2026, $832,750 (one unit) in all 77 Oklahoma counties — the national baseline, with no county above it. The county table on this page lists the two-, three- and four-unit figures. Above the limit, the loan is jumbo and follows lender rules.

When can I cancel PMI on a conventional loan in Oklahoma?

Federal law, not Oklahoma law, sets the dates: request at 80% of original value, automatic at 78%, and in any case at the loan’s midpoint. On the median Oklahoma price with 5% down at an illustrative 6.5%, that is roughly 10 years and 4 months and 11 years and 3 months respectively if you only make the scheduled payment.

Does Oklahoma add anything to a conventional loan’s closing costs?

Oklahoma levies a mortgage tax under 68 O.S. § 1904 on the note, graduated by term and topping out at 10 cents per $100 of principal for mortgages of five years or longer, plus a small certification fee, and the county treasurer must stamp the mortgage as paid before the clerk will record it; the borrower customarily pays it. Oklahoma’s documentary stamp tax is $0.75 per $500 (0.15%), paid by the seller; there is no mortgage tax beyond a small mortgage registration fee. Oklahoma buyer closing costs typically total 2% to 3% of a low price; abstract and title opinion practices persist in parts of the state alongside title insurance.
