How to Account for Vacant Lots in Your MHP Financials

Vacant lots are the opportunity and the liability of mobile home park ownership. They represent potential income not yet realized — and in the meantime, they still cost you money. Understanding how to account for them correctly on your financial statements, how buyers and lenders see them, and what the IRS allows you to do with them is fundamental to running a well-managed park.

Get this wrong and you’ll show inflated expenses, understated income, or a financial picture that doesn’t hold up during due diligence. Get it right and you have a defensible, lender-ready set of financials that accurately tell your park’s story.

Vacant Lots and Gross Scheduled Income

Gross Scheduled Income (GSI) is the starting point for every MHP income analysis. GSI represents the total annual income your park would generate if every lot were occupied and paying at market rent — with zero vacancy.

This is where many MHP owners make their first accounting error: they calculate GSI based only on occupied lots, then show no vacancy line. That approach hides the vacancy problem and produces a misleading NOI.

The correct approach: GSI must include all lots — occupied and vacant — priced at market lot rent. If your park has 100 lots at $400/month market rent, your GSI is $480,000 per year whether you have 80 lots occupied or 95. The difference is captured in your vacancy and credit loss line.

Physical Occupancy vs. Economic Occupancy

Lenders and buyers evaluate vacancy using two distinct metrics, and you need to understand both.

Physical occupancy measures what percentage of lots have a home on them and a resident in place. If 65 of your 80 lots have occupied homes, your physical occupancy is 81.25%.

Economic occupancy measures what percentage of your maximum possible income you’re actually collecting. This accounts for non-paying residents, concessions, and delinquencies. A park with 65 occupied lots but 5 residents not paying is at 81.25% physical occupancy but may be at 75% or lower economic occupancy.

Lenders underwriting a loan on your MHP focus heavily on economic occupancy because that’s what debt service comes from. Physical occupancy can be a vanity metric if residents aren’t actually paying.

For tax reporting purposes, you only recognize income that is actually collected (cash basis) or earned (accrual basis). Physical occupancy doesn’t create income — rent payment does.

Maintenance Costs on Vacant Lots: Deductible or Not?

Yes — maintenance costs on vacant lots are deductible as ordinary and necessary business expenses under IRC §162. The IRS does not require a lot to be occupied to allow a deduction for maintaining it as a business asset.

Typical deductible vacant lot expenses include:

• Mowing and landscaping to maintain appearance and park standards
• Debris removal and cleanup
• Utility line maintenance (even if not actively serving a home)
• Pest control for vacant pads
• Snow removal on vacant lot roads and pads (if applicable)

The business purpose is straightforward: you’re maintaining the lots to make them rentable and to preserve the overall appearance and value of the park. Both are legitimate business purposes. Keep receipts and note which costs relate to vacant lots if your accounting system separates them — though this level of detail is generally not required for tax purposes.

Depreciation on Vacant Lots

Depreciation on land improvements serving vacant lots continues even when those lots are unoccupied. This surprises many MHP owners who assume depreciation is tied to occupancy or income generation.

The IRS rule is simpler than that: depreciation begins when an asset is “placed in service” — meaning when it’s ready and available for use. A developed lot with roads, utility connections, and a pad that’s ready to receive a home is in service even without a resident. Depreciation on the infrastructure continues uninterrupted regardless of whether any particular lot is occupied.

This means your depreciation schedule is unaffected by vacancy fluctuations. A park going through a lease-up period after acquisition still generates full depreciation on all developed infrastructure from day one.

Presenting Vacant Lots in Due Diligence

When you’re selling your MHP, vacant lots are scrutinized intensely by buyers and their lenders. The key distinction buyers want to understand is between two types of vacancy:

Structural vacancy occurs when a lot cannot be filled — it has a physical problem, lacks utility service, is too small for modern homes, has site access issues, or is in an undesirable part of the park. Structural vacancy is effectively permanent and is treated as a reduction in the park’s rentable capacity, not a lease-up opportunity.

Lease-up vacancy occurs when a developed, ready lot simply lacks a resident — it’s a timing issue, not an infrastructure issue. Buyers will underwrite lease-up vacancy at a lower vacancy loss than structural vacancy, and may even project income growth as lots fill.

Your job in due diligence is to clearly categorize every vacant lot, document its condition, and explain why it’s vacant. Buyers who can’t tell the difference will underwrite everything as structural vacancy — which significantly reduces their offer.

Infill Strategy: The Tax Perspective

Filling vacant lots is the fastest way to grow NOI in a mobile home park. From a tax perspective, the infill strategy you choose has different implications depending on what you’re doing.

Acquiring a Park-Owned Home (POH) for Infill

When you purchase a manufactured home to place on a vacant lot and rent it to a resident, you’ve acquired a new depreciable asset. Manufactured homes placed in service as rental property are generally depreciated as 5-year personal property under MACRS. If bonus depreciation applies, a significant portion of the home’s cost may be deductible in the acquisition year.

The home purchase creates a new asset on your depreciation schedule, separate from the land improvements already in place on the lot.

Site Preparation for New Home Placement

If a vacant lot requires new or upgraded utility connections, a new concrete pad, or other site work to receive a home, those costs are typically 15-year land improvements — capitalized and depreciated, potentially with bonus depreciation. In some cases, minor site prep (grading, small utility extensions) may qualify as a current repair depending on the nature and scope of the work.

Coordinate with your CPA before assuming site prep is immediately deductible. The IRS tangible property regulations apply here.
