What is AI manufactured housing agency debt DSCR loan sizing? AI manufactured housing agency debt DSCR loan sizing is the use of artificial intelligence to estimate how large a Fannie Mae or Freddie Mac loan a manufactured housing community can support, by running the same debt service coverage ratio (DSCR), debt yield, and loan-to-value (LTV) tests the agencies use, against current rates and the property's trailing income. Agency debt is the most attractive capital in the manufactured housing world, offering long terms, non-recourse structures, and high leverage, but the proceeds you actually get are governed by hard sizing rules. AI lets you estimate those proceeds in minutes before you ever call a lender. For the wider context, see our guide to AI manufactured housing community management.
Key Takeaways
- AI agency debt sizing estimates MHC loan proceeds by running DSCR, debt yield, and LTV tests against current agency terms, so you know your likely loan amount before applying.
- Fannie Mae and Freddie Mac typically require a minimum DSCR around 1.25x and allow up to 80% LTV on purchases and 75% on refinances for qualifying communities.
- Most agency MHC programs require a minimum number of pad sites, commonly 50, so very small parks may need a different capital source.
- Freddie Mac has required tenant site lease protections on all new MHC loans since late 2021, and AI can check a community's leases against those requirements.
- Whichever of DSCR, debt yield, or LTV produces the smallest loan is the binding constraint, and AI identifies it instantly so you size to reality, not to hope.
Why Agency Debt Is the Prize in Manufactured Housing
Manufactured housing communities, often called mobile home parks, are one of the few asset classes where Fannie Mae and Freddie Mac actively lend through their Duty to Serve mandate. That matters because agency debt usually carries lower rates, longer terms, and non-recourse structures that local banks rarely match. The catch is that agency loans are sized by formula, not by relationship. The lender computes the maximum loan three ways and takes the lowest. If you assume bank-style flexibility and budget for proceeds the agency formula will not deliver, you can blow up a deal at the closing table. AI removes that risk by replicating the sizing math up front, which is why it belongs alongside AI capital planning in any MHC acquisition workflow.
The Three Tests That Size an Agency Loan
Agency loan sizing comes down to three constraints. AI computes all three from the community's trailing twelve month financials and the current rate, then reports the binding one.
- DSCR test: The loan must keep NOI at or above a multiple of annual debt service, commonly 1.25x for fixed-rate agency loans. Proceeds are capped at the amount whose debt service equals NOI divided by 1.25. A higher rate raises debt service and lowers the supportable loan.
- Debt yield test: NOI divided by the loan amount must meet the agency floor. Because debt yield ignores the rate, it often becomes the binding constraint in a higher-rate market. At a 9% floor, $450,000 of NOI supports a $5,000,000 loan.
- LTV test: The loan cannot exceed a percentage of appraised value, up to 80% on purchases and 75% on refinances for qualifying communities, with lower ceilings in smaller or pre-review markets.
According to the Fannie Mae Multifamily Guide, DSCR and LTV are calculated on defined terms that AI can apply consistently across every deal you screen. The output is a single sentence you can act on: your supportable loan is roughly X dollars, constrained by debt yield, at the current rate.
Here is the math in practice. Suppose a 120-pad community produces $600,000 of agency-eligible NOI after stripping out park-owned home income. At a 1.25x DSCR and a 6.5% rate on a 30-year amortization, the supportable loan is the amount whose annual debt service equals $480,000, which pencils near $6,300,000. At a 9% debt yield floor, the cap is $600,000 divided by 0.09, or about $6,670,000. If 75% LTV on a $9,000,000 value allows $6,750,000, then DSCR is the binding constraint and your realistic proceeds are about $6,300,000, not the $6,750,000 the LTV ceiling alone implied. That $450,000 difference is exactly the kind of gap that derails a deal when an owner budgets off the LTV number. AI surfaces the binding test instantly, so you negotiate, structure, and reserve capital against the real proceeds figure. The AI Consulting Network builds these agency sizing calculators for manufactured housing operators so the proceeds estimate is ready before the first lender call.
What Makes MHC Agency Sizing Different
Manufactured housing has its own quirks that change the sizing math, and AI can account for each. The first is income mix. A community that owns and rents many of its homes earns park-owned home income, which agencies discount or exclude because it behaves more like a business than real estate. AI can strip park-owned home income out of NOI to estimate the agency-eligible figure, which is often lower than the owner expects. The second is pad count. Most agency MHC programs require a minimum number of pad sites, commonly 50, so a 28-pad park may not qualify for standard agency execution at all. The third is condition and infrastructure, since aging water, sewer, and electrical systems can trigger larger replacement reserves that reduce net proceeds. For a deeper look at how condition flows into value, see our work on AI manufactured housing valuation.
Tenant Protections and Loan Eligibility
Since late 2021, Freddie Mac has required tenant site lease protections on all new manufactured housing community loans, and Fannie Mae offers similar incentives under the Federal Housing Finance Agency Duty to Serve framework. These protections include one-year renewable leases, 30-day written notice of rent increases, a grace period for late payments, the right of a resident to sell their home in place, and at least 60-day notice of a community sale or closure. This is not optional fine print, it is an eligibility gate: if your leases do not conform, the loan does not close as quoted. AI can scan a community's existing lease forms against the required protections and flag the gaps before you apply, turning a potential closing surprise into a pre-application checklist. The Federal Housing Finance Agency documents how these requirements support both residents and the broader agency lending program.
The AI Sizing Workflow
- Step 1, normalize the income: Feed the AI the trailing twelve month operating statement and ask it to separate lot rent from park-owned home income, then compute agency-eligible NOI.
- Step 2, set current terms: Provide the current agency rate, the relevant minimum DSCR, the debt yield floor, and the LTV ceiling for the market type.
- Step 3, run all three tests: Have the AI compute supportable proceeds under DSCR, debt yield, and LTV, and report the binding constraint.
- Step 4, check eligibility gates: Confirm pad count meets the program minimum and scan the leases against the required tenant protections.
- Step 5, stress test: Re-run the sizing at a higher rate and a lower NOI to see how fragile the proceeds are before you commit.

Frequently Asked Questions
Q: What DSCR do Fannie Mae and Freddie Mac require for MHC loans?
A: A minimum DSCR around 1.25x is standard for fixed-rate agency loans on qualifying manufactured housing communities, though the exact figure varies by program, market type, and whether the loan carries an interest-only period. Floating-rate and full interest-only structures often require a higher coverage ratio.
Q: How much can I borrow against an MHC through the agencies?
A: Up to roughly 80% LTV on a purchase and 75% on a refinance for qualifying communities, but the binding limit is usually whichever of DSCR, debt yield, or LTV produces the smallest loan. In a higher-rate market, the debt yield floor frequently caps proceeds below the LTV ceiling.
Q: Does my park need a minimum number of sites for agency debt?
A: Most agency manufactured housing programs require a minimum number of pad sites, commonly 50. Smaller communities may not qualify for standard agency execution and often turn to small-balance programs, local banks, or credit unions instead.
Q: Why does AI strip out park-owned home income when sizing agency debt?
A: Agencies treat income from homes the community owns and rents as business income rather than real estate income, so they discount or exclude it from NOI for sizing. AI separates lot rent from park-owned home income to estimate the agency-eligible NOI, which gives a far more realistic proceeds figure.
Q: Do I have to offer tenant lease protections to get a Freddie Mac MHC loan?
A: Yes. Since late 2021, Freddie Mac has required tenant site lease protections on all new manufactured housing community loans, including renewable leases, notice of rent increases, a payment grace period, and the right to sell a home in place. AI can check your existing leases against these requirements before you apply.
