How the Lender Determines Property Classification
When a borrower applies for a mortgage on a townhouse-style property, the lender determines the legal classification through several sources. The appraisal report identifies the property type. The title commitment describes the legal interest being conveyed (lot ownership vs. condominium unit). The preliminary title search reveals whether the property is part of a recorded condominium declaration or a PUD plat. The MLS listing may provide initial guidance, though MLS classifications are not always accurate for mortgage purposes.
If the property is classified as a PUD, the lender confirms PUD membership and proceeds with a standard residential underwriting workflow. The appraiser uses Form 1004, the same form used for single-family homes, with additional notes about the PUD characteristics and HOA fees. The underwriter verifies that no adverse conditions exist and that the HOA fees are factored into the DTI calculation.
If the property is classified as a condominium, the lender initiates the condo project review process in parallel with the borrower underwriting. This dual-track approach is identical to the process described on the condo mortgage requirements page: the HOA questionnaire is ordered, insurance and financial documents are collected, and the project is evaluated against warrantability criteria.
Loan-Level Price Adjustments and Pricing
Fannie Mae and Freddie Mac pricing treatment differs by classification. PUDs are generally priced the same as single-family residences with no additional LLPAs for property type. Condominiums carry specific LLPAs that add cost. This pricing differential can be meaningful: a property classified as a condo might carry an additional LLPA of 0.375% to 0.75% depending on LTV, which translates to a higher interest rate or upfront fee compared to the same structure classified as a PUD .
This pricing difference is one reason why the legal classification matters beyond just the review process. A borrower purchasing a townhouse in a PUD development benefits from single-family-equivalent pricing, while a borrower purchasing a physically identical unit in a condo-classified development pays more. Builders and developers who structure new townhouse communities as PUDs rather than condominiums may be doing so in part to provide their buyers with more favorable financing terms.
Down Payment Requirements
Down payment requirements for PUDs mirror those for single-family residences across all loan programs. Conventional loans are available with as little as 3% down (for eligible first-time buyers) or 5% down for standard borrowers. FHA requires 3.5% down. VA requires zero down for eligible veterans. USDA requires zero down in eligible areas.
For townhouse condominiums, down payment requirements are the same as for other condo units, which are generally equivalent to single-family requirements for warrantable projects. However, non-warrantable townhouse condos face the same elevated down payment requirements as any non-warrantable condo: typically 20-25% minimum through portfolio or non-QM lenders.
This creates a scenario where two adjacent, identical-looking townhouses can have dramatically different minimum down payments if one is in a warrantable condo development and the other is in a non-warrantable condo development. The PUD next door might offer 3% down conventional financing. These differences underscore why understanding the legal classification and project warrantability is essential before committing to a purchase.
Detached Condos and Attached PUDs
Adding to the classification complexity, detached units can be structured as condominiums, and attached units can be structured as PUDs. A development of detached single-family-looking homes can be organized under a condominium declaration if the developer chose that structure (perhaps to retain control of certain amenities or to simplify exterior maintenance through the association). Conversely, a row of attached townhouses can be platted as individual lots in a PUD.
The physical appearance is never determinative. Lenders, appraisers, and title companies look at the recorded legal documents to determine how the property is classified. Borrowers and agents who rely on visual inspection or MLS descriptions may be surprised when the underwriting process reveals a different classification than expected. This is why pulling the title commitment and reviewing the CC&Rs early in the transaction is a best practice.
Refinancing Considerations
Refinancing a townhouse or PUD follows the same classification-dependent process. A PUD refinance is straightforward, mirroring a single-family refinance with standard documentation. A townhouse condo refinance triggers the condo project review, which must confirm current warrantability status at the time of refinancing, not at the original purchase. A project that was warrantable at purchase could become non-warrantable if conditions have changed (higher investor concentration, lapsed insurance, new litigation), limiting the refinance options available to the unit owner.
