How Is Income Qualified If I’m Carrying Both Properties?

Income qualification is one of the more nuanced aspects of the Buy Before You Sell process. How both property payments are treated for DTI purposes depends heavily on which program structure is used and what documentation is available.

Scenario 1 — Departing Residence Excluded from DTI

In many BBYS program structures, the departing residence payment is excluded from your DTI calculation entirely. This is typically possible when:

• The BBYS provider has taken a lien or advance position on the departing residence
• A signed listing agreement is in place showing the property is actively for sale
• Sufficient equity exists to cover the outstanding mortgage from sale proceeds

In this scenario, you only need to qualify on the new purchase payment plus your other debts — making the math much more manageable.

Scenario 2 — Both Payments Included in DTI

In some structures, particularly bridge loan arrangements, the lender may require you to qualify carrying both the new mortgage payment and the existing departing residence payment. This is more conservative and requires stronger income to support both obligations simultaneously.

Rental Income Option

If you intend to rent out the departing residence during the transition, documented rental income may offset the payment for DTI purposes. Typically 75% of the monthly rent can be applied as an income offset, subject to documentation requirements.

Two sets of paperwork

For your income and the new home:

• Recent paystubs and W-2s, or business bank statements and a profit-and-loss statement for self-employed borrowers.
• Two to three months of asset statements for funds to close.
• The purchase contract and earnest-money proof.

For the departing home:

• The latest mortgage statement showing the payoff and payment.
• Most recent property tax bill and homeowner’s insurance declarations.
• The signed listing agreement and, if applicable, a lease.
• HOA statement, if there is one.

Stress-test the equity (illustrative example, not a quote)

Suppose the home is listed at $1,000,000 with a $550,000 mortgage, so the gross equity is $450,000. If the home eventually sells for $950,000, gross equity drops to $400,000, a reduction of $50,000. Selling costs reduce it further. Because exclusion of the old payment depends on sufficient equity, a lower price can alter the numbers, so test the lower value before committing.

Variable and self-employed income

If your income varies, underwriters generally average it over a period instead of using your best month. Ask how many months of history your program requires, and bring a stable-looking picture, such as consistent deposits and a profit-and-loss statement that reconciles to bank activity. Alternative documentation, including bank statements or asset depletion, can sometimes provide a stronger qualifying figure than tax returns.

A note on timing

Underwriters read the departing-home file at the same time as the new-home file, so a missing item on either side can stall both. A single folder with everything labeled, covering ID, income, assets, the contract, the listing agreement, and the old mortgage statement, is the simplest way to avoid back-and-forth.

Frequently asked questions

What if the house is rented before it sells?

Rental income counted at 75% can offset the old payment. A lease and proof of deposit are the core documents.

Do I need to show the departing home is not overleveraged?

Equity is central. Underwriters want to see enough value over the mortgage to pay it off from sale proceeds, which is why a net sheet from your agent helps.

Can I use bonus or commission income?

Often yes, with a documented history. How long a history and how it is averaged vary by program and borrower profile; we confirm the current guidelines when we review your scenario.

Quick recap

• Have documents for the new home and the departing home ready together.
• A drop in sale price directly reduces equity; test a lower value before you commit.
• Income documentation method can matter as much as the amount.
