The Quick Read: For a property that just switched from a lease to nightly bookings, the lender has to pick one of two income stories: the projection of what the property should earn as an Airbnb, or the actual hosting record, which is still thin. Projection helps when there is little STR history. Hosting history carries more weight once it seasons. Across the wholesale network, the lease record usually works as a fallback or a downside check, not as the main income figure.
- A projection is an estimate. Hosting history is proof. Lenders weigh the two differently.
- Short-term-rental programs typically expect about 12 months of hosting experience.
- Short-term-rental purchase leverage tops out at 75% LTV, and refinance and cash-out top out around 70%.
- The appraisal gives value and a rent schedule. It does not prove Airbnb income.
- DSCR measures rent against PITIA only. Clearing the coverage floor is not the same as positive cash flow.
The honest answer: a projection is for the owner who converted recently and has no track record yet. Rental history is for the owner who has been hosting long enough to document it. Neither is better in the abstract. The file decides which one the lender will accept.
Side-by-Side
The columns below describe how each income basis typically works across select lenders in Lendmire’s wholesale network. Specific terms vary by program, and every file is underwritten individually.
| Factor | Projected STR income | Rental (hosting) history |
|---|---|---|
| What it is | Data-service or appraiser estimate | Actual booking income, documented |
| Review basis | Property-level income covering PITIA | Property-level income covering PITIA |
| Documentation | Projection report, comps, STR addendum | Platform statements, payouts, bank deposits |
| Strongest on | Recent conversions, purchases | Seasoned hosts, refinances |
| Weakness | Estimate, often discounted | Few months after a conversion |
| Entity vesting | Names must match across documents | Names must match across documents |
| Reserve expectations | Vary by lender, leverage, loan size | Vary by lender, leverage, loan size |
| Property types | 1-4 unit investment property; not offered for manufactured, log, or barndominium | Same |
Both columns share one gate. The property must be a non-owner-occupied investment property, and short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Why the Appraisal Doesn’t Settle It
The appraisal is where most conversion files get confused. Fannie Mae’s appraiser guidance explains that Form 1007 documents estimated monthly market rent on a single-family investment property. It also notes that short-term rentals differ from leases: they book nightly, they include furniture, fixtures and equipment, and they run on terms-and-conditions agreements. That guidance is useful only for what the form measures. DSCR loans are not agency products, and program terms govern.
McKissock, an appraiser-education provider, summarizes the practical limits. The 1007 was not designed for STRs. Appraisers cannot multiply a nightly rate by 30. They value the real property, not the furnishings or the business income. Income is the lender’s decision. For two-to-four-unit properties the equivalent is Form 1025.
Some appraisers add a separate STR income narrative. Class Valuation, an appraisal management company, describes an addendum built on STR comps, occupancy, and seasonal pricing, and says the 1007 alone often produces an artificially low coverage ratio on STRs. That addendum is optional and not standardized. If a conversion file leans on one, order an appraiser who does STR work.
How Underwriters Read Each Income Basis
Think of the file as three documents answering three questions.
The lease record. It shows the property rented, who paid, and for how much. It proves the unit is rentable. On a converted property it cannot prove Airbnb income, and on most STR programs it is not the income that drives lender review. It is useful as a floor: if the projection fails, what does the property earn on a lease?
The projection. A data-service report or appraiser analysis estimates occupancy and nightly rate based on comparable listings. Lenders usually treat it as an estimate and may discount it. The size of any adjustment is program-specific, so it belongs in the lender conversation, not in your assumptions.
The hosting history. Platform statements, payout reports, and matching bank deposits show what the property actually earned. This is the strongest evidence. After a conversion, only the months since the switch count.
When Projected STR Income Is the Better Fit
Projection fits a handful of situations.
- A recent conversion with a short record. The property switched a few months ago. There is not enough history to show a season, so the projection carries the file.
- A purchase with STR intent. The buyer has no history on this property at all. Across the network, STR purchase files rely on projection, with leverage up to 75% LTV on the strongest files and a 1.00 coverage floor.
- A lease-based number that understates the property. A 1007 rent figure can sit well below what the property earns nightly. If the property is reviewed on projection, coverage can rise, and loan size can rise with it. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
The tradeoff is leverage and flexibility. Programs may apply tighter terms when there is no history. A projection also needs to be defensible. Tight comps, a conservative occupancy input, and a check against live listings make it easier for a lender to accept. A projection built on the most optimistic comps invites a discount, or a decline.
Timing is a financing strategy. Closing early means relying on the projection or a long-term fallback. Waiting lets a refinance use proven income instead.
When Rental History Is the Better Fit
History fits when there is enough of it.
- A seasoned host. Programs typically expect about 12 months of hosting experience. An owner at or past that mark has the strongest evidence: a trailing record that includes a full peak season.
- A refinance or cash-out. Projection is weaker evidence on a property the borrower already owns, because the lender can see actual earnings. STR refinance runs around 70% LTV and cash-out around 70% on STR collateral, with a 1.00 coverage floor on refinances. Refinance files lean on history.
- A projection that sits far above actual results. If the gap is wide, the lender will see it. The real record usually wins, and a clean one avoids a re-pricing conversation.
An investor whose rehabbed Airbnb had been operating about two months was told the lender wanted 12 months of history or the appraiser’s STR value. Commenters pointed toward lenders that accept pro forma income and appraisers familiar with STRs. That is the conversion problem in one file: too few months to prove it, so the decision turns on which route the lender allows.
Reconciling a Big Gap Between the Two Numbers
Say the projection comes in well above the old lease income. Underwriters read the gap as a question: why is the property expected to earn this much more? Work through it in order.
1. Check the comps. Are they the same bedroom count, amenity tier, and location type?
2. Check the occupancy assumption against the live market, not a peak month.
3. Check seasonality. Does the trailing period include a full peak season, or only one?
4. Compare against early actual bookings, if any exist. Real months beat estimated ones.
5. Run the lease record as a floor. If coverage still clears on lease income, the file has a safety net.
If the projection comes in below the lease, that is its own signal. It can mean the property is a better long-term rental than an Airbnb. Some programs use the more conservative of the projected and actual figures, and others use the higher, so ask before assuming.
A practical rule: a projection a lender can verify against comps is worth more than a larger one it has to take on faith.
Conversion Timeline and Documents
A conversion moves through stages, and each one produces a different document.
1. Lease ends or is not renewed. Keep the lease record, rent payments, and the move-out paperwork. This becomes the fallback evidence.
2. Setup and launch. Furnishing, listing, insurance that names short-term use, and proof the property can lawfully operate as an STR.
3. Early bookings. Open the platform account in the borrowing entity’s name and route payouts to a dedicated account. Mixed personal deposits are a common pitfall.
4. Seasoning. Platform exports, payout reports, and matching bank statements accumulate. Missing months weaken the record.
5. Refinance or purchase review. The lender picks the basis, applies any adjustment, and divides by PITIA to test the coverage floor.
Entity names must match across the deed, platform account, bank account, and insurance. A DSCR loan means no personal-income documents. It does not mean no documents. Property-level income, ownership, and reserve documents are still required, and entity vesting is subject to lender program eligibility.
Practitioner View: Where Conversion Files Stall
Across the files that come through the wholesale network, conversions stall for plain reasons, not exotic ones. The projection and the appraisal disagree and nobody planned for it. The platform export has gaps. The insurance policy still reads as a long-term rental. The entity on the listing differs from the entity on the deed. Fixing these before the file goes in is cheaper than answering them after.
A second pattern: reserves. They vary by lender, leverage, loan size, and transaction type. Many files see about six months of PITIA, and larger balances typically step up. Treat reserve documentation as part of the income file, not an afterthought.
One more point. Coverage is rent against PITIA only. Clearing 1.00 does not mean positive cash flow. Cleaning, utilities, platform fees, furnishing, management, vacancy, and capex all sit outside the calculation, and STRs carry more of them than leases do. Underwrite the property’s real operating margin separately.
Common Misconceptions
- Nightly rate times 30 equals monthly rent. The appraiser guidance above rejects that shortcut.
- The appraisal proves Airbnb income. The appraiser values the real estate. The lender decides the income.
- Projection equals actual. Projections are estimates and may be discounted. History from the property itself is stronger.
- Agency rules apply. DSCR loans are business-purpose investor loans. Agency appraisal-form guidance applies only to what the forms measure.
Key Terms Defined
Projected STR income: An estimate of nightly-rental earnings from a data service or an appraiser’s STR analysis.
Rental history: Documented actual income, shown through platform statements, payouts, and bank deposits.
Track record: Enough months of real hosting results to show how the property performs across a season.
Form 1007 and Form 1025: Appraisal forms that report market rent, 1007 for one unit and 1025 for two to four units.
DSCR: Monthly rent divided by the full monthly obligation of principal, interest, taxes, insurance, and any HOA dues.
Which Basis Fits Which Owner
| Situation | Likely basis | Why |
|---|---|---|
| Converted recently, few months of bookings | Projection | Not enough history yet |
| Hosting about a year or more | History | Strongest evidence |
| Buying with STR intent | Projection | No history on the property |
| Refinancing a seasoned STR | History | Lender sees actual earnings |
| Projection far above actual | History | Gap invites scrutiny |
The Balanced Verdict
Neither basis wins on its own. Projection gets a recent conversion into the conversation. History gets a seasoned property the strongest file. The lease record sits behind both as a floor. Plan the sequence: document from the first booking, keep entities consistent, and decide early whether the file goes in on projection or waits for the record to season. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Do I need rental history to finance an Airbnb conversion?
Not always. Programs that accept a projection can review a file with little hosting history. Others want about 12 months of history first. STR programs typically expect around a year of hosting experience, so the answer depends on the lender and program.
Does my old lease record still matter?
Yes, as a fallback and a stress test. It shows the property rents and gives the lender a floor if the STR numbers disappoint. It usually is not the income that qualifies an STR loan.
What if my projection is lower than my lease income?
It is a warning worth reading. Some programs use the more conservative figure, others the higher. Ask which applies before ordering reports, and consider whether the property fits better as a long-term rental.
How long until actual history outweighs the projection?
There is no single cutoff. Many programs look for about 12 months, ideally including a full peak season. Before that, expect the projection to carry more of the file.
What should I order first?
Order the appraisal, which returns value and a rent schedule, and ask whether an STR income addendum is available. Then assemble platform statements or a projection report depending on the basis you are using.
