The FHA Energy Efficient Mortgage (EEM) is one of the least-used but genuinely useful features of FHA financing: it lets you roll the cost of qualifying energy improvements — new insulation, high-efficiency HVAC, better windows, air sealing — into your loan amount, rather than paying for them separately or skipping them because the cash isn't there at closing.
What EEM actually does
Instead of treating energy upgrades as a personal expense on top of the mortgage, EEM adds a defined cost-effective energy package to the loan amount. "Cost-effective" has a specific meaning under HUD Handbook 4000.1: the projected energy savings over the useful life of the improvement must equal or exceed the cost of the improvement, as determined by the required energy assessment.
EEM is available with FHA purchase loans (203(b)) and with FHA refinances, and can be layered with a 203(k) rehabilitation loan for borrowers doing structural work at the same time.
The cap formula
The maximum dollar amount that can be added to the loan for energy improvements is the lesser of:
- 5% of the property's value
- 115% of the median area home price (for the relevant area)
- 150% of the FHA conforming loan limit for the area
| Formula input | Example figure | Resulting cap |
|---|---|---|
| 5% of property value | Home valued at $320,000 | $16,000 |
| 115% of median area price | Median area price $300,000 | $345,000 |
| 150% of area FHA loan limit | Area limit $420,000 | $630,000 |
| Amount financeable | Lesser of the three | $16,000 |
Illustration only — actual caps depend on your specific property value, county median price, and current FHA loan limit. In this example, the 5% of value rule is the binding constraint even though the other two ceilings are far higher, which is typical — the value-based cap is usually what limits the EEM package in practice.
The required home energy assessment
Before the improvement package is finalized, a qualified assessor must conduct a home energy assessment of the property. This assessment:
- Identifies specific improvements (insulation, air sealing, duct sealing, high-efficiency HVAC, windows, water heating, etc.)
- Estimates the energy savings and useful life of each improvement
- Determines which improvements meet the cost-effectiveness test — savings must equal or exceed cost over the improvement's life
- Produces the documentation the lender uses to set the final EEM add-on amount
Only improvements that pass the cost-effectiveness test can be financed under EEM; a borrower can't simply pick a wish list of upgrades and expect the full amount approved.
Combining EEM with 203(b) or 203(k)
- With a 203(b) standard purchase: the EEM package is added on top of the base 203(b) loan amount, covering appliances, systems, and envelope upgrades identified by the assessment.
- With a 203(k) rehabilitation loan: EEM improvements can be included alongside structural repairs and renovations financed through 203(k), letting one loan cover both a leaking roof and a new high-efficiency furnace, for example. See our 203(k) consultant guide for how the consultant, work write-up, and draw process function on that side of the loan.
Combining programs adds documentation — you'll be working with both a 203(k) consultant (if applicable) and an energy assessor — so build extra time into your purchase or refinance timeline.
FHA Solar and Wind Technologies
Separate from the standard EEM cost-effective package, FHA's Solar and Wind Technologies provisions allow the cost of a solar or wind energy system to be included in the FHA-insured mortgage under specific program conditions. This is typically evaluated alongside or in conjunction with EEM improvements rather than as a completely standalone product, and lender familiarity with this feature varies — not every lender processes solar/wind financing routinely, so confirm capability early if this is central to your plan.
Checklist: pursuing an FHA EEM
- [ ] Confirm your lender originates and processes FHA EEM loans (not all do routinely)
- [ ] Schedule a home energy assessment with a qualified assessor
- [ ] Review the assessment's list of cost-effective improvements
- [ ] Calculate the three cap figures (5% of value, 115% of median area price, 150% of loan limit) and identify the lesser
- [ ] Decide whether structural repairs also need a 203(k), separate from EEM
- [ ] Ask whether a solar or wind system needs its own program track
- [ ] Confirm how the EEM add-on affects your total loan amount, MIP, and monthly payment using the MIP calculator
Why this matters beyond the loan amount
Financing energy improvements at mortgage-rate interest, amortized over the loan term, is typically far cheaper than financing the same improvements on a credit card or personal loan — and it lets a buyer address efficiency issues (an aging furnace, poor insulation) that a standard FHA appraisal wouldn't necessarily flag as a Minimum Property Requirement issue but that materially affect the home's ongoing cost to own. Review the full purchase-eligibility picture at /requirements before assuming EEM changes your baseline qualifying standards — it doesn't; it only changes how much you can finance and what for.
