Sign the lease on the departing house before applying for the next mortgage, or apply first

Question

Take a live-in-then-rent buyer at month 11 in the current house, deciding between two orders of operations, with lenders giving conflicting guidance on which one helps. Order A: find a tenant, sign a lease that starts the week of move-out, collect the deposit, then apply for the next owner-occupant loan with a signed lease and deposit receipt in hand. The advantage is that a documented lease is often what lets an underwriter apply rental income against the payment on the departing house, which is the offset needed to qualify. The cost is committing to a tenant and a move-out date before an approval or a new property under contract exists, so a slipped purchase timeline means paying for a short-term rental in between. Order B: get approved and under contract first, then market the current house for rent. Cleaner sequencing, no dangling commitment. But underwriting then carries the full payment on the current house with no documented rent to offset it, which can push the debt to income ratio into the mid-40s. Some lenders will use a market rent figure from the appraisal instead of a lease; others require a signed lease and proof of the deposit clearing. Getting both answers in writing before choosing is the right move, since guidance varies enough between lenders that verbal answers are not reliable. Applying for a new owner-occupant loan while marketing the current home for rent is a normal part of this strategy and does not by itself raise intent concerns, provided the file stays consistent about timing and occupancy. Buyers who have done several of these tend to favor Order A specifically because the ratio math rarely works cleanly without a documented lease, even though it means carrying more commitment risk earlier in the process.

Order A with one change. Set the lease start date two weeks after the target closing on the new house rather than the same week. Closings slip by four days all the time and a tenant's movers do not care why, which is how these turn into hotel weeks. Two weeks of vacancy costs about 900 in that rent range and buys the ability to be a person during the move.

45 seems close to the edge already. Does the lease offset actually move it enough, or are you optimizing the wrong number?

diane_kowalski · Answer

@megan_doyle15 that's my question too. If a documented lease takes 45 down to 41 and the ceiling is 45ish depending on the program, then the lease is the whole approval and order B isn't really available to you. If it takes you to 43, you were fine either way and you should pick the order that's less stressful.

The mechanism you're asking about has two separate parts, and mixing them is where these threads go wrong.

First, how rental income gets counted. Underwriters generally apply only a portion of gross rent, commonly 75 percent, to offset the payment on a property you're converting, on the theory that vacancy and repairs consume the rest. The documentation they'll accept for that rent varies. Some programs allow a market rent figure from an appraiser's rent schedule when the property has no rental history, others want an executed lease plus evidence the deposit or first month cleared your account. Agency guidelines set a floor and individual lenders add overlays on top, so two lenders quoting the same program can genuinely give you different answers. Get the documentation requirement and the offset percentage from the underwriter in writing before you commit to a tenant.

Second, your ratio math. At 45 with the full departing payment counted, the question is how much of that payment the offset erases. If the departing house's payment is 1,400 and 75 percent of a 1,900 lease is 1,425, the payment can be fully covered and the ratio effect is large. If rent is 1,500, the offset covers 1,125 and you still carry 275 a month. Run both versions with your actual income before you decide which order matters.

On intent, applying for owner-occupant financing while marketing your current home for rent is a normal pattern in this strategy, and what matters is that your stated intent to occupy the new property is true and your file says the same thing everywhere. If you have any doubt about how your specific facts read, that's a conversation with your loan officer's compliance side or an attorney, not a forum.

The 75 percent number is the part most people get wrong. Only 75 percent of the lease counts against the departing payment, which makes the whole ladder harder than it looks.

@rena-expert's second example is @carlosnunez's actual problem. If 75 percent of achievable rent does not cover the departing payment, no ordering trick fixes it, and the difference gets carried into the next application every single time the move is repeated. The number that decides whether rung four exists is whether each converted house rents for roughly 1.35 times its payment, and the lease timing is secondary to that. @carlosnunez, what is the ratio on the house you are leaving?
