Investors search luxury spec construction vs bank construction-to-perm after a private banker says the file is “for your primary only.” Those are different products. Jaken Finance Group funds investment inventory — specs you intend to sell or carry as a rental. Banks and construction-to-perm programs fund residences — homes the borrower will occupy.
This comparison is educational. Verify any bank’s current construction sheet before you model 30-year debt.

How we compare
- Typical bank construction-to-perm and private bank jumbo timelines — not a live scrape of every lender.
- Jaken Finance Group investor parameters: 8.99%–13.5% interest-only, up to 100% LTC on qualified luxury files up to $2.5M, 75% LTARV cap.
- Occupancy is the first fork. If you will not live there, stop shopping construction-to-perm.
Side-by-side: private lender, private bank, construction-to-perm
| Factor | Private lender — luxury spec (JFG) | Private bank — jumbo construction (typical) | Construction-to-perm (typical) |
|---|---|---|---|
| Occupancy | Investment only | Usually owner-occupant or second home | Primary residence you will live in |
| Intent | Spec for resale or hold | Custom home for HNW client | Build then convert to permanent mortgage |
| Qualification | Asset, exit, experience, liquidity | W-2, tax returns, net worth, DTI | Full income, builder approval, plans |
| Property | Teardown, vacant lot, mid-vertical OK | Often approved builder and plans pre-close | Plans to finished primary |
| Rate shape | 8.99%–13.5% interest-only | Lower IO during build, then amortizing perm | Build phase IO, converts to 30-year perm |
| Leverage | Up to 100% LTC qualified to $2.5M; 75% LTARV binds | 65%–80% LTC common on primary construction | 80%–90% LTV on completed value at conversion — with cash in |
| Close | 10–14 business days complete file | 30–60 days | 45–75 days |
| Draws | Milestone inspections, investor schedule | Bank inspects to builder contract | Bank inspects to builder contract |
| Best use | Luxury spec, teardown inventory, $900K–$2.5M exit | Wealthy client building one-off primary | Family building the house they will occupy |
| Exit | Sale, luxury bridge, DSCR on completed hold | Live in it — perm at CO | Mandatory occupancy — perm at CO |
If the house is inventory, construction-to-perm is the wrong form. If the house is your residence, private spec debt is the wrong cost structure.
When private luxury construction is the only path
You will list the home. Construction-to-perm covenants assume occupancy. Listing a spec while that covenant is live triggers default risk on bank paper — not a private lender product problem, but a fatal mismatch on bank paper.
The lot is investor-owned in an LLC. Business-purpose title and draw control match private construction. Many bank construction desks want individual occupancy and personal guarantee on primary debt.
You need speed on the land. Ten to fourteen business days on a complete file beats a 45-day private bank committee for a spec pod in Buckhead or Paradise Valley.
Vertical already started. Banks rarely inherit another lender’s stalled spec. Mid-construction refinance is private money territory.
Income is complex; collateral is clean. Sponsors with entity stacks, K-1 partners, or foreign-national capital fit asset-based underwriting. Bank construction wants documentable personal income on the occupant — who does not exist on a spec.
You model up to 100% LTC on a qualified $1.4M–$2.5M file. Banks do not offer that on investor spec. See eligibility matrix.
When private bank or construction-to-perm wins
You will occupy the home. A 6.75%–7.25% 30-year jumbo after conversion beats 11% interest-only if you hold for a decade. That only works if you actually live there.
The builder is on the bank’s approved list. Production-adjacent custom builders with bank history get smoother draws than a one-off spec GC the bank has never seen.
You can document income and wait. Full tax returns, 45–60 days, and a jumbo overlay you clear — normal for Memorial or Belle Meade primary construction.
You want one close to permanent. Construction-to-perm eliminates the takeout refinance at CO — valuable for a primary, irrelevant for a spec you will sell to someone else’s jumbo.
Your all-in is below private money concentration. A $900K primary build with 25% down and strong income may price better at a private bank than 13% IO — if occupancy is real.
Honest comparison: bank wins on cost for real primaries. Private lender wins on occupancy, speed, leverage, and investor intent.
Worked example: same lot, two sponsors
A tear-down lot in Brookhaven, Atlanta supports $1.55 million finished O-O custom per comps.
Sponsor A — primary build. Construction-to-perm through a regional bank. 20% down on completed value. Income documentation. Builder from bank list. 14-month vertical. Converts to 30-year jumbo at CO at roughly 6.9% amortizing. Sponsor must occupy within 60 days of CO. Total private cost lower over 10 years if they stay.
Sponsor B — spec build. Private luxury new construction. All-in $1.42M. As-completed $1.55M. 75% LTARV = $1,162,500. 82% LTC effective advance ~$1,162,000. 11% IO, 14-month vertical, 90-day DOM reserve. Exit: retail buyer who may themselves need a bank jumbo — that buyer’s mortgage is not Sponsor B’s construction loan.
Sponsor B cannot use Sponsor A’s term sheet. Sponsor A cannot list in month three without violating occupancy covenants.
Worked example: Naples coastal — flood and timing
Collier coastal lot, Flood Zone V, finished target $1.85M.
Bank path: Possible for primary on elevated pile design — 6–9 months extra engineering, flood insurance quote, builder compliance. 45% down sometimes on coastal construction. Still requires occupancy.
Private spec path: Milestone draws with flood cert and elevation certificate gates. All-in $1.68M with 12% contingency on coastal vertical. 75% LTARV on $1.85M = $1,387,500 advance. Interest reserve through 18-month vertical plus 100+ DOM coastal thin pool.
Bank wins for HNW primary who will insure and occupy. Private lender wins for investor spec who will list after CO.
Private bank vs private lender — do not conflate
“Private bank” in wealth management often means jumbo for clients — still occupancy-tested, still slower, still not spec inventory.
“Private lender” here means hard money and construction credit on business-purpose real estate — the investor construction lane at Jaken Finance Group.
Some investors hear “private” and assume one conversation covers both. Bring the occupancy box first. The wrong box wastes three weeks.
Cost of capital over hold period
11% IO on $1.1M average drawn ≈ $10,100/month. 7% amortizing jumbo on $1.1M is lower per month and builds equity — if both loans can exist.
On vacant land with no occupant, only the IO line exists. Compare all-in dollars for months you hold construction debt, not a rate trophy on a product you cannot access.
Add origination points, builder’s risk, appraisal, extension fees, and minimum interest on private notes. Add discount points and jumbo adjustments on bank perm. Six-month hold on private may still beat missing the land deal.
Appraisal types differ
| Appraisal | Used for |
|---|---|
| As-completed with plans | Private luxury construction sizing |
| As-is livable | Bank jumbo purchase |
| Primary construction progress | Bank draw inspections |
Do not paste a bank primary appraisal onto an investor spec pro forma. The bank report assumed occupancy and a kitchen you may not have built yet.
After CO — spec exit vs perm conversion
Construction-to-perm: Converts at CO. Borrower keeps the house. Debt amortizes.
Luxury spec: Lists at CO or during final draws with municipality permission. Buyer may need 45-day jumbo. If DOM runs long, luxury bridge carries without pretending the construction loan is perm-eligible.
Completed hold: DSCR at 70%–75% LTV on newly completed spec — not 85% purchase DSCR on day one after CO.

Draw gates — private spec vs bank construction
Both products use milestone draws. The release criteria differ in ways that matter mid-build.
| Gate | Private luxury spec (JFG) | Bank construction-to-perm |
|---|---|---|
| Occupancy attestation | None — investment purpose | Borrower certifies future primary occupancy |
| Builder approval | GC track record and license | Often approved builder list only |
| Draw inspector | Third-party construction inspector | Bank staff or assigned firm |
| Change orders | Sponsor liquidity or contingency | Bank re-underwrites material scope change |
| Mid-build switch-in | Mid-construction refinance lane | Rare — usually full restart |
A bank that stalls at framing because the GC is not on the approved list does not owe you a spec timeline. Private construction can inherit the vertical if draw history, lien waivers, and as-completed comps support the file — but only as a new private note, not a construction-to-perm conversion.
Insurance — spec inventory vs primary residence build
| Coverage | Investor spec (private) | Primary construction-to-perm |
|---|---|---|
| Builder’s risk | Required; lender named | Required; lender named |
| Flood / wind (coastal) | Quote in budget; affects buyer exit | Borrower carries post-CO as occupant |
| Occupancy misrepresentation | N/A — investment declared | Material breach if listed for sale at CO |
| Premium at CO | Buyer problem on resale | Rolled into owner PITI |
On a Naples Flood V spec, the bank primary path assumes you will insure and occupy at actuarial flood rates. The private spec path assumes your buyer will — model that in list price and DOM, not just construction cost.
Comp mistakes when shopping the wrong product
Investors sometimes bring a bank primary comp packet to a spec underwriting desk:
- Appraisal ordered for owner-occupant conversion — wrong occupancy box.
- Comps from production master-planned communities on a deed-restricted tear-down lot.
- As-completed value anchored to custom build-to-order timelines the spec cannot match on finish.
- Active neighbor listings used as sold support because the bank pre-approval used them.
Fix the occupancy fork first. Then rebuild the comp fence for the buyer who will purchase your inventory — often a jumbo end-buyer whose own bank timeline is 45 days, not your construction term.
Seasonal listing — why construction-to-perm timing does not transfer
Construction-to-perm borrowers care about move-in date before school starts. Spec sponsors care about list date relative to jumbo buyer seasonality:
- Arizona and Vegas: October–April list window; July CO into heat needs bridge reserve.
- Coastal Florida: January–April snowbird peak; August list into storm awareness extends DOM.
- Houston energy corridor: Q1–Q2 bonus-driven buyers; December CO into holidays adds 30+ days.
Bank construction schedules around your occupancy. Private spec schedules around someone else’s jumbo approval — a carry cost construction-to-perm never models because that product forbids the listing.
Worked example — mid-build switch after bank decline
Situation: Brookhaven tear-down, $1.38M drawn on bank construction at framing. Bank declines change order for $48K tree-buffer redesign. Vertical stalled.
| Item | Bank path (failed) | Private mid-build path |
|---|---|---|
| Outstanding debt | $1,380,000 bank IO | Payoff via private construction refi |
| Remaining vertical | $420,000 budget | Same — GC contract continues |
| As-completed support | $1,995,000 (unchanged) | Same comp fence — Brookhaven only |
| New advance sizing | N/A | 75% LTARV on $1,995,000 = $1,496,250 less payoff |
| Sponsor cash | N/A | Gap plus IO reserve on remaining 8 months |
This is not construction-to-perm conversion. It is private money finishing inventory the bank will not fund — common on intown Atlanta tear-downs where tree ordinance surprises mid-vertical.
