Rate lock, Ginnie Mae and what actually sets your rate

A 221(d)(4) note rate is assembled from parts. Two of them are fixed by Ginnie Mae, one is set by the bond market on the day you lock, and one you choose.

Reviewed September 2026

The 221(d)(4) prices tightly because the loan becomes a government-guaranteed security. Understanding how that security is built tells you which parts of your rate are negotiable and which are not.

When you lock

The borrower locks after HUD issues the firm commitment and before initial endorsement. The sequence is not arbitrary: the firm commitment fixes the insured loan amount and terms, and that is what makes the loan securitizable and therefore priceable.

A good faith deposit is customary at lock — 0.50% is the figure generally quoted, though it is market practice rather than a HUD-published requirement. The MAP Guide addresses interest rate lock in its own section of Chapter 11, immediately after the section covering firm commitment issuance and extensions.

Remember the firm commitment carries a 60-day term. That is the window in which the lock, the closing preparation and initial endorsement all have to happen, which is why rate lock tends to concentrate at the front of it.

What security gets issued

A 221(d)(4) is endorsed for insurance of advances, which means the security is issued progressively as construction proceeds.

A useful distinction: “CL” pools carry the same rate on the construction and permanent security; “CS” pools have differing rates. Which structure your lender uses affects your construction-period cost.

This is also why cost certification sits on the critical path: final endorsement is what converts the construction certificates to the permanent security.

The spread you cannot negotiate

Ginnie Mae sets the servicing and guaranty layer by rule. For project loan pools:

ComponentAmount
Ginnie Mae guaranty fee13 basis points
Minimum servicing fee, exclusive of guaranty12 basis points
Minimum total spread, note rate over security rate25 basis points
Maximum without prior written Ginnie Mae approval50 basis points

So your note rate equals the Ginnie Mae security coupon plus somewhere between 25 and 50 basis points, plus the MIP — now a flat 0.25% across all FHA multifamily programs. The 25-basis-point floor is structural. The distance between 25 and 50 is where your lender’s servicing economics sit, and it is a fair question to ask about.

The spread you cannot control

The security’s own spread to Treasuries is set by the bond market on the day you lock. Investors in Ginnie Mae project loans price against prepayment risk — refinancing incentive, property appreciation, loan size, property type — and against call protection, default risk and underwriting tightness. The market convention prices at 15% CPJ: the project loan default curve plus a flat 15% CPR on voluntary prepayments after lockout.

Most certificates are securitized into multi-tranche REMICs with sequential-pay classes of roughly three to twelve year average lives. The securities carry an explicit full-faith-and-credit United States guarantee of timely principal and interest and a zero risk weighting for bank capital purposes — which is precisely why the execution prices where it does.

One quirk worth knowing: converted construction loan certificates have historically prepaid faster than certificates that began life as project loans, which investors price for.

The part you choose

Call protection is the genuine borrower decision. Prepayment terms are negotiable — a two-year lockout followed by a stepdown premium is a common structure. Longer and stronger call protection makes the security more attractive to investors and improves your coupon; it also constrains what you can do with the asset. That trade is yours to make and it is worth modelling against your actual hold period rather than accepting a default structure.

Why this site publishes no interest rate. Any rate quoted on a website is a snapshot of a bond market that moved before you read it, on a structure that may not be yours. Rate is a function of the day you lock, the call protection you choose and the servicing spread you negotiate. Get it quoted by a MAP-approved lender, for your deal, with the prepayment structure you actually want.

Putting it together

Four components, in descending order of how much influence you have over them: the call protection you choose; the servicing spread you negotiate within the 25-to-50 basis point band; the Ginnie Mae guaranty fee of 13 basis points and the 0.25% MIP, both fixed; and the bond market on lock day, which is nobody’s to control. Knowing which is which keeps the conversation with your lender on the parts that are actually open.
