Florida Mortgage Income Requirements: How Lenders Calculate What You Earn
Lenders don't use your gross salary — they calculate "qualifying income," which can be higher or lower than what you actually make. Here's how it works.
Gross Income vs. Qualifying Income
Mortgage lenders calculate your qualifying income — not your take-home pay, not your gross salary, not what's in your bank account. Qualifying income is a standardized calculation based on your documented income sources, averaged over time according to Fannie Mae/Freddie Mac guidelines (for conventional) or HUD guidelines (for FHA).
Key point: Your qualifying income may be lower than your gross income if you have variable pay, recent job changes, or business deductions. It may also include income sources you didn't think to mention — rental income, alimony, pension, or investment distributions.
Income Types and How Each Is Calculated
Base Salary (W2)
The simplest case. Lenders use your current gross monthly salary, verified by recent pay stubs and 2 years of W2s. If your salary hasn't changed, they use the current figure. If it's increased, they use the current rate.
Hourly Wages
Current hourly rate × average weekly hours × 52 ÷ 12 = monthly income. If your hours vary, lenders use a 2-year YTD average from your pay stubs and W2s. Consistent 40 hours/week is treated like salary. Variable hours are averaged.
Overtime Income
Overtime must be documented for at least 2 years to be counted. Lenders calculate the average monthly overtime over 24 months. If your employer indicates overtime is "not guaranteed," it may be excluded. If overtime has declined year-over-year, lenders will typically use the declining year's figure (conservative approach).
Bonus Income
Same rules as overtime: 2-year documented history, likelihood of continuance, and the 2-year average is used. A first-year sign-on bonus doesn't count. An annual performance bonus averaged over 2 years typically does.
Commission Income
Commission is one of the most variable income types. Lenders calculate it as a 2-year average of commission income shown on W2s or 1099s. If your commission income is increasing, the higher recent figure may be used. If declining, expect the lower number. FL real estate agents, mortgage brokers, and salespeople frequently fall into this category.
| Income Type | Minimum History | How Calculated | Likely to Continue Required? |
|---|---|---|---|
| Base salary | Current (with W2 history) | Current monthly rate | Yes (VOE) |
| Hourly wages | Current + 2yr avg if variable | Current rate or 2yr avg | Yes |
| Overtime | 2 years | 24-month average | Yes |
| Bonus | 2 years | 24-month average | Yes |
| Commission | 2 years | 24-month average | Yes |
| Self-employment net income | 2 years | 2yr avg after add-backs | Yes (business viability) |
| Rental income | 2 years tax returns | 75% of gross rents minus expenses | Active lease required |
| Alimony / child support received | 6 months payment history | Monthly payment amount | Must continue 3+ years |
| Social Security / pension | Award letter / 1099-SSA | Monthly gross benefit | Non-taxable income grossed up 25% |
| Investment/dividend income | 2 years returns (Schedule B) | 2yr average | Account must still hold assets |
| Part-time second job | 2 years same employer | 2yr average | Yes (still working there) |
Rental Income: The Florida Opportunity
Florida's strong rental market means many buyers own investment or vacation properties. Rental income rules:
- Existing rentals: Lenders typically use 75% of gross rental income (Schedule E) minus PITIA (principal, interest, taxes, insurance, and HOA) on the rental. If the net is positive, it adds to your income. If negative (rental property costs more than it earns), it adds to your debt.
- Airbnb / short-term rental income: Most conventional lenders require 2 years of Schedule E history. Some non-QM programs accept 12 months of platform statements. Projected rents from a new STR purchase are rarely counted.
- Proposed rental on new investment property: Fannie Mae allows 75% of projected market rents (from an appraiser's rental schedule) to offset the new property's PITIA, but rules vary by program.
Non-Taxable Income: The Gross-Up
Social Security benefits, disability income, VA benefits, and some pension payments are non-taxable. Because these don't get taxed, mortgage lenders can "gross up" the income by 25% to make it comparable to taxable income for DTI calculations.
Example: $2,000/month in non-taxable disability income → grossed up to $2,500/month for mortgage qualification. This improves your qualifying power without changing your actual income.
Florida VA buyers: VA disability pay is non-taxable and grossed up. Combined with 0% down and no PMI, this often makes VA loans significantly easier to qualify for than their stated income suggests.
Income That Typically Does NOT Count
- Recent one-time bonuses (not 2-year history)
- Cash income not reported on tax returns
- Funds received from family members (gifts are assets, not income)
- Stock options/RSUs that haven't vested and been received
- Projected future income or raises
- Income from a second job held less than 2 years (in most cases)
- Gambling winnings (unless documented on tax returns for 2+ years as a profession)
Common mistake: Telling a lender about income you receive in cash that isn't on your tax returns. Lenders can only count documented income. Undocumented income can also raise compliance flags. If you have cash income, talk to a CPA about how to document it before applying.
How to Calculate Your Qualifying Income
A simplified example for a Florida buyer with mixed income:
That $6,300/month is what the lender uses for DTI calculations — not the $80,000/year salary alone.
