MHP Tenant Site Lease Protections Are a Model Input

Published November 8, 2026

Fannie Mae has required Tenant Site Lease Protections (TSLPs) in the loan documents for 100% of site leases, implemented within 12 months of origination, since January 1, 2022 (per Fannie Mae's MHC Mortgage Loan job aid). Freddie Mac announced the same posture for all future manufactured housing community transactions on September 13, 2021, effective immediately (per the Freddie Mac press release). Most Mobile Home Park (MHP) models still treat tenant site lease protections as a closing checklist item for counsel. They are closer to a rent-timing covenant, and on an illustrative 120-lot park pushing lot rent $75, the timing is worth roughly $65K of year-1 Net Operating Income (NOI) and something on the order of $660K of coverage-sized proceeds.

What Tenant Site Lease Protections Actually Require

The two programs converge on substance and diverge on day counts. The table below reflects Fannie Mae's MHC Mortgage Loan job aid and Freddie Mac's published tenant-protections summary for manufactured housing communities, both of which trace back to the Duty to Serve framework at 12 CFR 1282.33. Program documents are revised periodically — verify the operative version with the agency lender.

Two mechanics matter more than the list. First, Fannie Mae permits implementation either by amending each site lease or by adding the protections to the community's rules and regulations where the lease incorporates them by reference, with a written certification of 100% compliance inside the first loan year. Second, the pricing incentive attached to the protections is tied to non-profit or government ownership, so a for-profit buyer generally carries the covenant without the corresponding pricing benefit. That asymmetry is easy to miss when a lender quote and a lease covenant arrive in the same term sheet.

Why the 30-Day Notice Is Not the Binding Constraint

Underwriters tend to read the 30-day notice line, conclude the rent push slips a month, and move on. The one-year renewable term is the heavier constraint. A park bought with month-to-month tenancies can, in an unregulated state, generally notice the whole community at once and have a new rent in place roughly 30 to 45 days after closing. The same park under tenant site lease protections has to move those tenancies onto annual terms inside the first loan year, and once a lot is on a one-year lease renewable at the resident's election, the rent on that lot generally moves at its own anniversary.

The practical result is that a community-wide push becomes a staggered roll-through. Anniversary dates land where the amendment program put them, not where the model wanted them, and the stabilized run rate arrives a year or more after closing rather than in month two. This is a timing effect, not a cap: nothing in either program limits how large the increase may be. It is also distinct from statutory lot-rent caps, which do limit magnitude — see rent control as the MHP due-diligence frontline for that layer.

A 120-Lot Worked Example

Assume an illustrative 120-lot, Tenant-Owned Homes (TOH) park, all lots currently month-to-month at about $450, market lot rent around $525, so a $75 per lot per month push. Financing is agency, sized against a 1.25x Debt Service Coverage Ratio (DSCR) floor, at an illustrative 6.9% coupon on 30-year amortization — roughly a 7.9% debt constant with the 10-year Treasury at 4.94% (Federal Reserve H.15 via FRED, October 30, 2026). The amendment program runs months one through three; notices go out and the increase lands on about 10 lots a month from month four onward.

The arithmetic is simple enough to check by hand. Nine monthly batches of about 10 lots, landing in months four through 12, capture 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 lot-months each, or roughly 450 lot-months against the 1,320 a day-one push would produce. At $75 a lot-month that is about $33.8K versus about $99K — a year-1 gap of roughly $65K. Figures are illustrative and vary with the actual anniversary distribution.

That gap does two things. It moves cash, which is a distribution question, and it moves underwritten year-1 NOI, which is a sizing question. At a 1.25x floor, roughly $65K of NOI supports about $52K of annual debt service, and at a 7.9% constant that is on the order of $660K of proceeds. Whether the gap actually costs proceeds depends on which year the lender underwrites — a point covered in more depth in MHP agency debt when coverage is the binding constraint.

The Sell-In-Place Window Extends the Lot Recovery Clock

The post-eviction sell-in-place right — 45 days under Fannie Mae's job aid, 30 days per Freddie Mac's announcement — is a small number attached to a line most models do not carry at all. An abandoned or evicted home does not become a rentable or sellable lot on the eviction date. The sequence runs eviction, then the resident's window to sell the home in place, then whatever the state's abandoned-title process requires, then the turn itself.

On a park where a handful of lots are working through that sequence, adding roughly a month to the front of each recovery pushes the lot back into revenue a month later, and the lot carries expense the whole time. That is the kind of line that turns a clean economic-occupancy assumption into an optimistic one — the lot-by-lot approach in MHP economic occupancy underwriting is where this shows up. For the underlying mechanics, see mobile home park underwriting.

The Assignment Right Cuts Across a Home Sell-Down

Business plans that convert Park-Owned Homes (POH) to tenant ownership generally assume the park controls the sales channel. The assignment and For Sale sign protections cut against that. A resident may sell the home in place, assign the site lease to the buyer for the unexpired term without unreasonable restraint subject to the borrower's screening criteria, and advertise on the lot — which means resident-to-resident sales compete with the park's own inventory at prices the park does not set.

The effect on the model is not the lot rent, which is captured either way, and this is the distinction drawn in park-owned versus tenant-owned homes. The effect is on the non-realty sales margin and the pace of the sell-down, both of which tend to be modeled as if the park were the only seller. Sizing that line conservatively, or carrying it as basis recovery rather than as profit, is the more defensible posture. Outcomes vary considerably by market and by how much resident-owned inventory is already for sale.

Where This Breaks

The honest counter-case is that for many parks this is close to immaterial. A community already on annual leases with staggered anniversaries, bought without a step-change rent plan, sees almost none of the year-1 drag described above — the roll-through is already the status quo. Parks in states whose manufactured-home tenancy statutes already require one-year renewable leases, longer notice, and sell-in-place rights are in the same position: the agency covenant restates state law and changes nothing in the model.

The proceeds figure is also softer than it looks. Agency sizing generally leans on trailing and stabilized figures rather than a single projected year-1 NOI, so a timing gap inside year one may not reduce proceeds at all; it may simply defer distributions and compress year-1 coverage. And the roll-through assumption itself is a guess about anniversary distribution — a park whose amendment program concentrates renewals in a few months behaves differently from the even 10-a-month pattern above. The direction of the effect is reliable; the magnitude is not. Figures here are illustrative rather than quoted terms, and current program requirements are worth verifying directly with the agency lender.

The Bottom Line

Tenant site lease protections are generally not a rent cap and not a deal killer. What they do is decouple the date a rent increase is decided from the date it reaches each lot, extend the clock on lots recovered through eviction, and hand residents a sales channel the park does not control. A model that pushes lot rent community-wide in month two, recovers abandoned lots on the eviction date, and treats the home sell-down as a park monopoly is overstating year 1 on three lines at once. Routing each protection to the line it touches — timing to the rent schedule, the recovery window to economic occupancy, the assignment right to the non-realty margin — makes the covenant a known quantity rather than a first-year surprise. The exit arithmetic that sits on top of it is covered in MHP exit value.
