TL;DR
- Reconcile the signed lease and all amendments with dated rent receipts before using an advertised rent in your purchase model. A rent roll is a summary, not proof of collections.
- Separate rent for each period from refundable deposits, advance rent, concessions and unpaid balances. A large bank deposit does not prove a higher recurring rent.
- Build your own operating-cash forecast and get a separate lender qualification answer. Federal tax treatment is a third question, not a shortcut for either calculation.
- Resolve missing records and closing allocations before relying on the income. Do not assume buying the house cancels a lease or delivers vacant possession.
What makes the rent usable evidence?
An occupied house advertised at $1,800 a month does not yet provide $1,800 of spendable monthly income. Establish what the tenant owes, what has actually been paid, which period each payment covers and which expenses the owner must pay. Then decide what assumptions the evidence supports.
Use the exit comparison to choose between a sale and rental hold. This worksheet handles the occupied rental's existing income evidence, not the legal process for changing occupancy.
Ask the seller for the complete executed lease, renewals, amendments and written concessions; a dated tenant ledger; and receipts or redacted deposit evidence that can be matched to the ledger. Include any property manager's reporting and known disputed balances. Request relevant records through the authorized transaction process, not the tenant's unrelated financial history.
Match each claim to a record
| Seller's claim | Evidence to reconcile | What remains unresolved if it is missing |
|---|---|---|
| Current rent is $1,800 | Executed lease plus amendments and current term | Whether the advertised amount describes the actual agreement |
| Tenant is current | Charges, credits and dated receipts tied to periods | Whether a zero balance hides a concession or unposted payment |
| Extra cash was rent | Receipt purpose and the period covered | Whether the money is advance rent, deposit or another item |
| Tenant pays utilities | Lease responsibilities and current billing arrangements | Which expenses the buyer must carry |
| Income continues after closing | Occupancy terms and transaction-specific legal review | What obligations, credits and access limits continue |
Do not solve contradictory records by choosing the version with the highest rent. Record the disagreement, who can explain it and the deadline for getting the answer. If the lease says one amount and receipts show another, the difference needs a reason.
A fictional lease-versus-collection reconciliation
Invented records and amounts, not a real tenant or a forecast. A lease shows $1,800 due each month. The seller advertises $5,400 of rent for the last three months. The supplied records show:
| Period | Contractual charge | Documented concession | Rent cash received for that period | Unpaid balance for that period |
|---|---|---|---|---|
| Month 1 | $1,800 | $0 | $1,800 | $0 |
| Month 2 | $1,800 | $200 | $1,600 | $0 |
| Month 3 | $1,800 | $0 | $1,200 | $600 |
| Total | $5,400 | $200 | $4,600 | $600 |
The reconciliation is $5,400 minus $200 of documented concessions minus $600 unpaid = $4,600 received. No opening balance, late fees or other credits exist in this invented ledger. The $600 is not treated as cash merely because it is owed.
Suppose the seller also received a $1,800 refundable security deposit and $1,800 explicitly covering a later final rental month. Total documented inflows become $8,200: $4,600 + $1,800 + $1,800. Only $4,600 in this exercise is rent cash for the three periods shown. Do not divide $8,200 by three and call that ongoing monthly rent. Nor should the final month require collecting the same $1,800 again if that period was already paid.
The average rent cash received for these periods is $1,533.33 per month, rounded from $4,600 ÷ 3. That is a historical observation, not a reliable forecast from three months alone. Investigate the concession and shortfall before assuming either recurs or disappears.
Keep three different income answers separate
Your acquisition forecast estimates future collections minus operating costs, reserves and debt payments. If you use a collection allowance, identify what it covers so you do not deduct the same anticipated shortfall twice. Test the supported rent and unresolved downside in the BRRRR calculator, using a separate actual ledger for rent received before refinancing.
Your lender's qualifying income follows its loan program. Fannie Mae's rental-income guidance, for example, requires specified evidence that lease terms have taken effect in applicable cases and explanation of variances between documented income and the lease amount. The guide has additional borrower, property and documentation rules. It is not a universal formula for DSCR, hard-money or every investment loan. Ask the actual lender what it will accept and how that affects the loan.
Federal taxable rental income follows tax rules. IRS Publication 527 generally includes advance rent when received but excludes a security deposit intended to be returned. An amount called a deposit that pays final rent is advance rent under that guidance. These distinctions explain why the labels matter; they do not determine your state-law obligations, closing credits or future cash availability.
Turn missing evidence into a purchase condition
Before treating the income as supported, list the unresolved lease terms, balances, prepaid periods, deposit amounts and owner expenses. Have the appropriate closing and legal advisers confirm how the actual transaction handles them. A worksheet is not evidence that funds or obligations transfer automatically.
If income depends on raising rent, collecting old arrears or getting vacant possession, keep that separate from the documented current position. Do not fund the purchase with a hoped-for change presented as an accomplished fact. Revise the price, cash requirement or decision when the verified position no longer fits.
