Finance New Construction As A Second Home — The Quick Read: A borrower can finance a newly built second home using asset depletion, but only through a consumer-purpose non-QM mortgage that closes after the builder finishes and the local jurisdiction issues a certificate of occupancy. The asset depletion math converts liquid assets into a monthly income figure, which then supports a standard debt-to-income calculation. DSCR loans cannot be used here, because DSCR is limited to non-owner-occupied investment property and second-home personal use conflicts with that occupancy rule.
Key Takeaways
- Asset depletion works for a second home because it’s a consumer-purpose loan type, not because it’s a workaround for verifying repayment-capacity.
- New construction financing on this path is take-out financing. It pays the builder off after completion, not during the build.
- Second-home classification depends on personal use versus rental use, not just a borrower’s stated intent.
- Loan sizing through select wholesale programs runs from $300,000 to $30,000,000, with leverage stepping down as the loan gets bigger.
- Funds earmarked for a builder deposit and funds used to qualify on assets often compete for the same dollars — plan around what’s left at closing, not the pre-construction balance.
Why DSCR Isn’t The Vehicle Here
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they get reviewed differently from a standard owner-occupied mortgage. A second home, by definition, involves personal use, so it needs consumer-purpose financing instead. Anyone weighing the two paths can compare them directly in Lendmire’s complete DSCR loans guide. But here’s the short version: if the property will see meaningful personal use, DSCR is off the table from the start.
Key Terms Defined
Asset depletion (asset utilization). A qualification method that turns a borrower’s liquid assets into a hypothetical monthly income figure by dividing the eligible balance by a set number of months.
Second home. An occupancy classification for a property the borrower personally uses for part of the year — not a rental held mainly for income, and not subject to a rental pool that takes away the borrower’s control over bookings.
Certificate of occupancy (CO). A document issued by the local jurisdiction confirming a newly built home is legally safe to live in. Most lenders treat it as a hard prerequisite to closing.
Take-out financing. The permanent mortgage that replaces or pays off a builder’s construction costs once the home is finished. It is not the loan that funds the actual building work.
Debt-to-income (DTI). The ratio comparing a borrower’s monthly debt obligations against qualifying income, whether that income comes from a paycheck, self-employment deposits, or an asset depletion calculation.
How The Asset Depletion Math Actually Works
Asset depletion doesn’t measure net worth directly — it converts a slice of it into a monthly number a lender can plug into a DTI formula. The lender identifies eligible liquid assets, applies discounts by asset type, subtracts funds needed for the down payment, closing costs, and reserves, then divides what’s left by a set divisor.
Through select lenders in Lendmire’s wholesale network, this typically runs one of two ways. The first is an asset allowance path, which supplements other qualifying income by dividing liquid assets by 36 months when the borrower’s overall DTI sits at or below 60%, or by 60 months when it runs higher. A standalone asset allowance, or any loan above $3,500,000, generally uses an 84-month divisor instead. This path applies only to primary residences and second homes, and it typically caps around 80% loan-to-value on most files. The second is a separate assets-only path, which skips the DTI calculation entirely. Here, the borrower simply needs U.S.-based liquid assets equal to the loan amount plus closing costs, plus sixty months of coverage for any net loss on another residential property they own.
Asset type matters. Retirement accounts typically count at 70% of their value, rising to 80% once the borrower is 59.5 or older — the age past which withdrawals no longer trigger an early-withdrawal penalty. Business funds, gift funds, trusts other than a revocable living trust, unvested stock, and cryptocurrency generally don’t count toward eligible assets at all. That last detail catches a lot of high-net-worth borrowers off guard, since it’s common to have a meaningful share of net worth sitting in exactly those categories.
Across files like this, one pattern shows up often. Borrowers under 59.5 who plan to lean on a 401(k) or IRA balance sometimes find their coverage figure lower than expected, once the retirement-account discount applies. That’s precisely the borrower profile most likely to be building a second home years before retirement. To avoid a surprise late in the process, run the numbers on the actual eligible-asset total, not the account statement total.
The Occupancy Test: What Actually Makes A Home A “Second Home”
A property qualifies as a second home based on how it’s used, not on what the borrower calls it. Fannie Mae’s Selling Guide lays out the underlying distinction that non-QM investors borrow their terminology from. A principal residence is occupied by the borrower. An investment property is not occupied by the borrower at all. A second home sits in between — it’s a property kept mainly for the borrower’s own use.
Underwriters also check whether the location makes sense for genuine personal use. Gustan Cho Associates notes that a second home is typically expected to sit in an area where vacation or seasonal homes are common. A property built too close to the borrower’s existing residence can raise questions about whether it’s really an investment property in disguise. This distance-and-plausibility screen applies just as much to a newly built home as to an existing one. For example, a spec home going up a few miles from the borrower’s primary residence draws more scrutiny than a custom build in a lake or resort area two states away.
Light personal use paired with occasional short-term rental generally still fits a second-home structure. But sometimes rental income is the real purpose of the purchase, and personal use is minimal. In that case, the file usually needs to move to an investment-property classification instead. This reopens the DSCR conversation, but it closes the door on second-home pricing and asset-depletion eligibility for that occupancy type.
New Construction Mechanics: Two Appraisals, One Certificate
New construction financing runs on its own timeline, regardless of occupancy type or income method. The appraisal typically isn’t ordered until the build is substantially complete. The first report is usually written “subject to completion per plans and specifications,” rather than as a finished-property valuation. Once the builder wraps up, a second document — commonly a completion certification — confirms the work matches those plans.
A certificate of occupancy from the local building department is usually required before the loan can close. It’s worth being precise about what a CO actually confirms: it means the home is safe to occupy, not that every line item on the builder’s contract is finished. Landscaping, trim work, and minor punch-list items can still be outstanding even after the CO is issued — a distinction that trips up borrowers who assume CO in hand means the builder relationship is fully closed out.
The mortgage itself is take-out financing. It closes after the CO is issued and pays off or replaces whatever arrangement funded the actual construction — a builder deposit structure, a separate construction loan, or a combination of both. It does not fund the building process itself. That means the real completion-date risk sits with the builder and the municipal inspection schedule, not with the mortgage underwriting, assuming the asset-depletion file is otherwise clean.
Sizing And Leverage Through Select Wholesale Programs
Loan amounts for this kind of file typically run from $300,000 to $30,000,000 through two separate wholesale channels — a portfolio non-QM program carrying files to roughly $6,000,000, and a bank portfolio program that carries files further out on its own ladder: around 65% loan-to-value to $5,000,000, 60% to $10,000,000, and 55% up to $30,000,000, generally structured interest-only at 60% or the band’s ceiling, whichever is lower.
Leverage on a second home steps down as the loan gets bigger, and every figure here is a ceiling reviewed under full underwriting, not a guarantee. On most files in the $300,000-to-$1,000,000 range, purchase leverage on a second home can reach roughly 85% with credit around 700 or better. That ceiling narrows through the $1,000,000-to-$3,000,000 bands, and above roughly $3,000,000 it typically steps down further, generally requiring stronger credit as the loan size climbs. Anything above $4,000,000 is reviewed case by case before submission — never treated as an automatic “up to” figure, and second-home leverage above that threshold sits meaningfully below what a comparable primary residence file might see.
Reserve requirements scale with loan size too — typically three months of payments up to $500,000, six months up to $1,500,000, and nine months above that on most files, plus roughly two additional months per other financed property the borrower carries. On the credit side, a 660 floor is common on the portfolio program, rising to 700 for larger loans above the super-jumbo threshold.

Where The Funds Compete With Each Other
New construction contracts often run many months between signing and closing. During that window, the same pool of liquid assets often has to cover a builder deposit, upgrade costs, and the eventual down payment — while also serving as the balance the asset-depletion calculation is built on. Large deposits or transfers into an account close to closing can also trigger sourcing requirements. The practical takeaway: plan the asset-depletion math around the balance that will actually remain at closing, not the balance sitting in the account today.
What Can Go Wrong
Two things derail these files more than anything else. First, ordering the appraisal too early — before the builder is substantially finished — forces a second round of paperwork and can stall the file regardless of how strong the borrower’s asset picture looks. Second, treating the property’s classification as a formality. If personal use turns out to be minimal and rental income becomes the real driver, the loan doesn’t quietly stay a second home — it needs to be reclassified, and that reclassification can change both the leverage available and the loan type itself.
This is not legal or tax advice. Financing structures, occupancy classifications, and asset-qualification rules involve individual circumstances that a qualified attorney or CPA should review before a borrower relies on any specific approach.
Frequently Asked Questions
Can a DSCR loan finance a second home under construction? No. DSCR loans require the borrower to certify that neither they nor a family member will occupy the property, which directly conflicts with second-home personal use. A consumer-purpose asset-depletion or bank-statement structure is the correct fit instead.
Does the mortgage fund the actual construction? Generally not through this path. The asset-depletion mortgage is take-out financing that closes once the home is complete and the certificate of occupancy is issued. The build itself is typically funded through a builder deposit structure or a separate construction loan.
What happens if the borrower plans to rent the home out sometimes? Occasional short-term rental alongside primarily personal use can still fit a second-home structure. But if rental income becomes the main reason for the purchase, the file usually needs to shift toward investment-property classification, which changes both the leverage and the loan type available.
Do retirement accounts count fully toward the asset depletion calculation? Not always at full value. On most files, retirement balances count around 70% for borrowers younger than 59.5, rising to about 80% once the borrower crosses that age, since earlier withdrawals typically carry a penalty.
What size loans can this structure handle? Loan amounts through select wholesale programs typically run from $300,000 up to $30,000,000, with leverage generally stepping down as the loan size increases and every file above roughly $4,000,000 reviewed case by case before submission.
