Qualifying for the Next Washington Home While You Still Own This One
Program and regulatory figures verified September 19, 2026. Details change; confirm your scenario with us.
Two different tests, and people usually only run one. Underwriting decides whether you are approved. Net proceeds decide whether the plan ends cleanly.
The underwriting test
When you buy before selling, both housing payments are live. The departing home's principal, interest, taxes, insurance and any association dues count, and so do the new home's. Underwriting asks whether documented income supports the total alongside your other obligations.
It does not discount a payment because your market is fast, and it does not credit you for the equity that will arrive later. It measures the obligations you carry now.
The test people skip
Whether the exit works.
If you borrow to bridge the gap, that borrowing is repaid at the departing home's closing from what the sale produces after excise tax, the existing mortgage payoff, commissions and costs. In Washington the excise tax line alone is roughly 1.65% of the price where a 0.50% local REET applies.
A file can pass underwriting comfortably and still leave a borrower short at the second closing if the bridge was sized against the gross price. Both tests have to pass. Worked through on the net proceeds page.
What actually closes a gap
- Rental income on the departing home. Under B3-3.8-05 a positive figure offsets that property's own payment and does not add qualifying income.
- A larger down payment from other liquidity, which lowers the new payment directly.
- Paying down other obligations. Car and card payments sit in the same ratio and are often easier to move.
- Financing against the departing home's equity, which in Washington carries no state transaction tax.
- Choosing a lower price. Unglamorous and frequently correct.
If your current home is under contract
A signed contract is not a closing. Until the departing home closes and there is a settlement statement, its payment typically stays in your ratios.
That window has been lengthening in most of Washington. Days to pending rose year over year in thirteen of seventeen metros, so a timeline that held in 2025 may not hold now. In Walla Walla the mean reached 71 days, in Aberdeen 70 and in Moses Lake 68.
Reserves
Requirements vary with the file, and converting the departing home to a rental brings six months of PITIA on the vacated property where the borrower has under 12 months of property management experience. That liquidity is usually also earmarked for the down payment, so map it early.
In King, Pierce and Snohomish, where the conforming limit reaches $1,063,750, jumbo reserve expectations can sit on top. See the jumbo page.
What makes a first conversation useful
Rough value and balance on the current home, the price range and county you are shopping in, your income picture, and an honest estimate of what the departing home would sell for. Approximations are fine.

Frequently asked questions
Do I have to sell my Washington home before qualifying for the next one?
No, provided documented income supports both housing payments at once alongside your other obligations. Separately, the plan has to work at the exit, since anything you borrow is repaid from net proceeds after excise tax, the existing payoff, commissions and costs.
Does underwriting account for Washington excise tax?
No. Underwriting measures the obligations you carry, not what your sale will net. Excise tax affects whether the payoff works rather than whether the file approves, which is why both questions need answering.
Does a pending sale remove my current mortgage from the calculation?
Generally not until it closes. Until a settlement statement exists the departing home's payment typically stays in your ratios. That matters more now, since days to pending rose year over year in thirteen of the seventeen Washington metros tracked.
Is it cheaper to borrow against my Washington home than to sell?
Borrowing carries no state transaction tax, because excise tax applies to sales rather than to recording a deed of trust. But the sale is still coming, and the tax arrives with it. Borrowing changes the timing of your access to equity, not whether the exit cost is paid.
