Tax Implications of Buying a Mobile Home Park With Seller Financing

By Harry Shurek, EA | The MHP Accountant®

Seller financing is common in the MHP market. The seller holds the note, you make payments directly to them, and the bank stays out of it. The deal terms are negotiable. The closing is faster. The financing is often more flexible than institutional debt.

But seller financing changes the tax picture for both sides of the transaction — and most buyers focus entirely on the deal structure without understanding the tax mechanics underneath it. Here is what you need to know as the buyer.

How Seller Financing Changes the Transaction Structure

In a conventional purchase, a bank funds the purchase price on closing day, the seller receives cash, and the buyer owes the bank. All the tax events happen at closing (or shortly after, once the return is filed).

In a seller-financed purchase, the seller receives a down payment at closing and a promissory note for the balance. The seller collects principal and interest payments over time. The buyer pays principal and interest to the seller instead of to a bank.

From the buyer’s perspective, the most important point is this: the purchase price — and therefore the basis — is the same whether you pay cash, use bank financing, or use seller financing. Your depreciable basis in the property is the total purchase price, not the down payment. Seller financing does not give you a lower basis.

Purchase Price Allocation Still Required

Regardless of how the purchase is financed, both buyer and seller are required to report the purchase price allocation on Form 8594 (Asset Acquisition Statement). This form allocates the total purchase price across asset classes — land, depreciable real property, personal property, intangibles, and going-concern value.

The allocation matters enormously for the buyer’s depreciation. If the allocation assigns more value to shorter-lived assets (land improvements, POHs) and less to longer-lived assets (structures, land), the buyer gets more depreciation earlier. If it assigns everything to land (not depreciable) or 39-year structures, the buyer gets far less.

Both parties must file consistent allocations. If the buyer and seller file inconsistent Form 8594 allocations, the IRS will notice. Negotiate the allocation before closing, document it in the purchase agreement, and make sure both Form 8594s match.

The Installment Sale — The Seller’s Perspective

The seller who provides financing is engaging in an installment sale under IRC Section 453. Under installment reporting, the seller recognizes gain ratably as principal payments are received — not all at once in the year of sale.

This is favorable for the seller in most cases, because it spreads the tax liability over the payment period rather than forcing a large tax bill in year one. But there is a critical exception that every MHP buyer should understand, because it affects how the seller prices and structures the deal.

Depreciation recapture (Section 1245 and Section 1250) is NOT eligible for installment reporting. Recapture income is recognized in full in the year of sale, regardless of when the payments are received. A seller with a large amount of accelerated depreciation — from bonus depreciation or cost segregation — faces immediate recapture tax even if they only receive a down payment in year one.

This is why some sellers are less enthusiastic about installment sales than buyers expect. The seller takes the recapture hit immediately but may be waiting years to collect enough principal to cover the tax liability. Understand this dynamic when you negotiate seller financing terms.

Interest Expense Deductibility for the Buyer

The interest you pay on a seller-financed note is deductible — but the rules depend on how the park is classified for tax purposes.

For most MHP operators, the park is a passive rental activity. Interest on debt used to acquire a passive rental property is treated as investment interest under IRC Section 163(d), subject to the investment interest limitation. In practice, for most MHP operators, the interest is fully deductible against the park’s rental income because the park generates passive income that offsets the investment interest.

If you materially participate in park operations (and qualify as a real estate professional), different rules apply — the interest is treated as a business expense, fully deductible without the passive activity overlay. See your tax advisor for the analysis that applies to your specific situation.

Imputed Interest Rules

If the interest rate in the seller-financing arrangement is too low — below the Applicable Federal Rate (AFR) published monthly by the IRS — the IRS will impute a market-rate interest to the transaction. This has two effects:

• The seller is taxed on interest income they did not actually receive (but are deemed to have received)
• The buyer’s principal payments are partially recharacterized as interest (deductible) rather than principal (non-deductible)

The IRS publishes the AFR monthly. For long-term seller notes (over 9 years), the long-term AFR applies. The rate is not high, but charging zero percent or below-market rates will trigger imputed interest. Make sure the note bears interest at or above the applicable AFR to avoid this complication.

You can find the current AFR on IRS.gov.

Balloon Payment Considerations

Many seller-financed MHP deals have balloon payments — the full remaining principal is due in 3, 5, or 7 years. From a tax perspective, the balloon payment is treated the same as any other principal payment. No special tax event is triggered by a balloon beyond the recognition of the principal received under the installment method (for the seller) and the extinguishment of the debt obligation (for the buyer).

The buyer’s practical concern with a balloon is refinancing or selling the park before the balloon comes due. If you plan to hold the park and refinance at the balloon, confirm that the park’s NOI will support a bank loan at that future date. If you plan to sell before the balloon, confirm that the seller note is assumable or payable at closing of a future sale. These are negotiating points at the original acquisition.

What Happens If the Seller Dies Holding the Note

Seller-financed notes are assets of the seller’s estate. If the seller dies before the note is fully paid off, the note passes to the seller’s heirs or estate. The buyer’s obligation continues — payments are now made to the estate or the note beneficiary rather than to the original seller.

From a tax perspective, the installment sale treatment continues. The estate or heirs continue to recognize gain as principal payments are received, under the same installment sale ratios as the original seller established.

For the buyer, the practical concern is ensuring that the promissory note clearly identifies what happens at the seller’s death — who the payments go to, how the payoff is handled, whether there is a due-on-death clause. Address this in the note itself, not after the fact.
