How lenders count a school contract, summer work or overtime

How Oklahoma school staff and first responders' pay is counted for a mortgage: 10-month contracts, summer school, new hires, overtime and shift pay, and how extra hours affect OHFA's income limit.

The short version:

Base pay on a school contract is the easy part. Freddie Mac, which backs OHFA's conventional Gold loan, divides annual pay by 12 even if you're paid over 10 months. Summer school, overtime and extra shifts usually need a track record, often two years, and lenders lean toward the lower figure if earnings dropped. One Oklahoma twist: OHFA's income limit counts the gross income of everyone 18 and older in the home, so extra hours that help you qualify can also push you toward the cap.

Two different questions about your pay

When you apply with OHFA 4 Schools or Shield, your pay gets looked at twice, for opposite reasons:

Can you afford the loan? The lender wants as much stable income as it can document, to keep your debt-to-income ratio under OHFA's cap of 45%, or up to 50% at a 680 score on government loans.
Are you under OHFA's income limit? OHFA counts the annualized gross income of every household member 18 and older. Here, more income can work against you.

Keep both in mind as you read the rest.

School employees

Ten months of checks, twelve months of salary

Plenty of Oklahoma teachers and support staff get paid only during the school year. Freddie Mac's guide, which governs OHFA's Gold Freddie loan, tells lenders to take your annual gross pay and divide by 12. Its own example is monthly pay times 10, divided by 12. So a $4,200 check paid 10 times becomes $3,500 a month for qualifying.

How FHA, VA and USDA handle a 10-month schedule wasn't confirmed for this guide. Your lender confirms the method on those loans.

Contracts and new hires

Freddie Mac treats a renewable school contract as support that your income will continue, unless the lender knows something different. That helps teachers in their first few years.

If you've signed a contract but haven't started, Freddie allows income that starts after closing in two ways. One requires a start date no more than 90 days after closing, plus proof you have money to cover your payments and debts until then, plus one month. The other has no day limit but you must start before the loan is delivered to Freddie. Either way, the pay has to be salary or guaranteed hours. FHA's handbook has no offer-letter rule, though it lets recent graduates count school as part of their two-year history.

Summer school and extra duty

Freddie classifies summer school as seasonal or secondary work. It says a teacher's summer income with less than two years of history can still be justified. Coaching stipends, bus routes and other extra-duty pay aren't spelled out in the guides we reviewed, so ask your lender how they'll treat each one and bring the paperwork.

Police, firefighters and EMS

Overtime and callback pay

For many officers and firefighters, overtime is a big piece of take-home pay. Lenders will count it, but they want history and they discount drops:

Loan	History	How it's averaged
FHA (OHFA Gold Government)	2 years, or at least 1 year if steady and likely to continue	The lower of the 2-year average or the most recent year's average
Freddie Mac (OHFA Gold Freddie)	2 years, 12 months if justified	Recent years plus year-to-date; if it's dropping, year-to-date only. A drop over 10% needs more review.

Worked example

These numbers are illustrative. A Lawton firefighter earns base pay of $52,000 a year. Overtime was $11,000 in 2024 and $8,000 in 2025.

FHA's two-year average is $9,500. The most recent year is $8,000. FHA uses the lower, $8,000, or about $667 a month.
Qualifying income is about $5,000 a month: $4,333 base plus $667 overtime.
On Freddie Mac, the drop from $11,000 to $8,000 is over 10%, so the lender has to look harder at why and whether it has leveled off.

Now the other side. If his household is three people in Comanche County, OHFA's Gold limit is $104,300. His $60,000 is well under. But if his spouse earns $48,000, the household is at $108,000 and over the limit, even though overtime helped him qualify for the loan. Run the household math before you shop.

Shift differential

Night and weekend differentials aren't named as a separate income type in FHA's, Fannie Mae's or Freddie Mac's guides. Lenders generally treat them like other variable pay, but that's not confirmed, so ask your lender.

A second job

Plenty of first responders work security, teach CPR or pick up shifts at a second agency. FHA wants two uninterrupted years of part-time income before counting it. Freddie wants two years in most cases, with 12 months possible if justified.

Volunteer service and the Shield rate

OHFA Shield covers people serving a volunteer fire department and reserve or volunteer officers. Your volunteer service can make you eligible for the special rate, while your regular job provides the income. That's common in small towns, where the welder or the rancher also runs fire calls. A participating lender verifies the service.

State employees

OHFA also gives its special rate to people working for a State of Oklahoma agency. The same pay rules apply: steady salary is simple, while overtime, stipends and second jobs need history. If you're moving from one state agency to another in the same kind of work, tell your lender up front and bring both offer letters.

Gaps and job changes

FHA: after a gap of six months or more, current income can count if you've been back at work at least six months and had two years of work history before the gap.
Freddie Mac: expects two years "in most instances," but allows less with a written reason, such as returning to work after a long absence or coming straight out of school or training.
Moving between districts or departments in the same line of work generally isn't a problem. A career change gets more questions.

What to bring

Your current contract or offer letter, signed
Recent pay stubs showing year-to-date earnings
W-2s for the last two years
A written breakdown of base, overtime, extra duty and stipends, if your employer will provide one
Income for every adult 18+ in the household, for OHFA's limit

Then check your eligibility. A lender can tell you which of your pay counts and how close you are to your county's limit.

Questions people ask

How do lenders count a 10-month teacher salary?

Freddie Mac, which backs OHFA's Gold conventional loan, divides your annual gross pay by 12. For FHA, VA and USDA loans, your lender confirms the method.

Does overtime count for a mortgage?

Usually, with history. FHA wants two years, or at least one year if it's steady, and uses the lower of the two-year average or the latest year. Freddie Mac wants two years, sometimes 12 months, and looks closely at drops over 10%.

Does my overtime count toward OHFA's income limit?

Yes. OHFA counts the annualized gross income of everyone 18 and older in the home, so overtime and a spouse's income count toward your county's cap.

Can I buy before my new school contract starts?

Possibly. Freddie Mac allows salary that starts after closing, with a start date within 90 days and proof you can cover payments until then, among other options. FHA has no offer-letter rule.

Can volunteer firefighters get the OHFA Shield rate?

Yes. Shield includes people currently serving a volunteer fire department. Your regular job can provide the income.
