Section 223(f) is a refinance and acquisition program, not a rehabilitation program. The line between the two is the substantial rehabilitation threshold: repair work that costs more than a stated amount per unit pushes the transaction out of 223(f) and into 221(d)(4), with its longer timeline, Davis-Bacon wage requirements and construction-period complexity.
That threshold is indexed. For 2026 the base figure is $20,406 per unit, set by Mortgagee Letter 2026-05 in May 2026. The 2025 figure was $19,948.
The field is anchored to $15,000. That was the base in the 2016 MAP Guide. Current lender guidelines and reference sites still publish $15,000, $15,536 and similar figures, which understates real repair capacity by roughly a third before the high-cost multiplier is even applied. We found no competitor site that mentions the annual indexing at all.
The base is only the start — apply the high-cost percentage
The per-unit threshold is multiplied by the high-cost percentage for the property's area, which is what makes the effective figure vary so widely by market. Mortgagee Letter 2026-05, effective January 1, 2026, sets those percentages:
| Area | Maximum increase | Resulting multiplier |
|---|---|---|
| Standard areas | up to 170% | 270% |
| Designated High Cost Areas | up to 215% | 315% |
| Alaska, Hawaii, Guam, U.S. Virgin Islands | — | capped at 405% |

The practical range is wide. In a standard-cost market the effective threshold is a multiple of the $20,406 base; in a high-cost coastal market it is meaningfully higher still. Before concluding that a repair scope is too large for 223(f), the threshold has to be computed for the actual property location — not quoted from a national figure.
What counts toward the aggregate
The test is not just hard construction cost. The aggregate figure includes the repairs themselves, the associated fees, and the completion assurance escrow. A scope that looks comfortably under the threshold on contractor pricing alone can breach it once those are added, which is a bad surprise late in an application.
Critical versus non-critical repairs
Repairs are identified by the Capital Needs Assessment and sorted by urgency. Critical repairs — life safety, code, accessibility, anything affecting habitability — must be completed before closing. Non-critical repairs are escrowed, typically at 120% of estimated cost, and must be completed within twelve months of closing.
That distinction drives the closing timeline more often than borrowers expect. A scope heavy in critical items means construction before closing, which means the rate lock has to be managed around work the borrower does not yet control.
When the scope is genuinely too large
If the aggregate exceeds the threshold, the path is 221(d)(4) substantial rehabilitation. That is a real program with real advantages — higher leverage against cost, and the ability to fund a gut renovation — but it is a different transaction: Davis-Bacon prevailing wages apply, the timeline lengthens considerably, and construction administration becomes part of the deal.
The decision is sometimes gameable at the margin. A scope just over the line can occasionally be re-sequenced, with some work done outside the FHA transaction and funded separately, keeping the insured refinance in 223(f). Whether that is worth doing depends on how much the deferred work costs to fund elsewhere, and it is a conversation to have with a MAP lender and the CNA provider early, not after the application is filed.
Separately, note that replacement reserves are a continuing obligation, not a one-time escrow. 223(f) requires an initial deposit set by the CNA plus an ongoing deposit of at least $250 per unit per year, with the CNA refreshed on a ten-year cycle.
