The Quick Read: The right line for a house you built yourself depends on three things: occupancy, credit profile, and combined leverage. None of it starts until the home is finished, has its certificate of occupancy, and sits in your own name or a revocable trust. Lendmire is a mortgage broker, so it shops this scenario across wholesale lenders instead of pushing one product. Every figure below is subject to lender guidelines and full file review.
- Timing: A line needs a finished, legally habitable home. A build in progress calls for construction financing, not a HELOC.
- Investment property: The network ceiling is 70% CLTV, with a 700 minimum credit profile and a maximum line of $500,000.
- Primary residence or second home: The ceiling reaches 90% CLTV only at a 720 credit profile or better.
- Vesting: Title must sit with the individual borrower or a revocable living trust. An LLC cannot hold title on these lines.
- Valuation: Lines at or below $500,000 usually run an automated valuation. A one-off custom build has thin comparable sales, so ask for a full appraisal when value is in question.
What Does Best Mean When You Built the House Yourself?
The best program is the one your finished file fits, not the one with the biggest headline number. Three filters decide it, in this order: occupancy, credit profile, then combined leverage.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Occupancy comes first because the ceilings differ sharply. A home you live in gets the most room. A second home gets a little less. A rental gets the least. Credit comes next, because each occupancy has its own minimum score and its own tiers. Leverage comes last, because CLTV counts every lien on the property, not just the new line.
There is no separate owner-built HELOC on the market, and no federal rule creates one. Each lender sets its own guidelines for a home with no builder history and no purchase price. That is why the same borrower can get different answers from different lenders.
This is where a broker earns its place. Lendmire works with a network of wholesale HELOC lenders. It matches your property, credit, and leverage need to the program that fits. It does not rank lenders or name a winner, because the best program for your situation depends on your file. Lines are available in Lendmire’s 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than the 41-market DSCR footprint, which includes Washington, D.C.
What Do the Network’s Lines Allow by Occupancy?
The ceiling depends on how the house is used. Occupancy is the first number to settle, because it caps everything else.
| Occupancy | Minimum credit | Top CLTV | Maximum line |
|---|---|---|---|
| Primary residence | 600 | 90% at 720+ | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 640 | 90% at 720+ | $500,000 |
| Investment property | 700 | 70% | $500,000 |
The top tiers are narrow. On a primary residence, 90% CLTV applies only at 720 or better and only up to $500,000. At 700 the ceiling on a primary residence is 85% up to $500,000, and at 640 it is 80%. A primary-residence line above $500,000 requires a full appraisal and caps at 75% CLTV. It needs a credit profile of 700 or better (720 on the longer-runway program described below).
Market surveys report that investment-property equity lines often ask for credit scores near 720 or higher and allow maximum LTV around 80%, per NerdWallet’s investment-property HELOC guide. Those are market-wide figures, not this network’s. On Lendmire’s network, an investment-property line tops out at 70% CLTV.
Other limits apply across occupancy types. Debt-to-income tops out at 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% needs a 680 minimum. Qualifying uses the interest-only payment on the maximum draw. A borrower can hold up to three lines, and a borrower with more than 15 financed properties is not eligible.
How Does Underwriting Treat an Owner-Built Home, Step by Step?
Underwriting treats an owner-built home like any finished property, with extra attention to the paper trail. A lender cannot measure equity in a structure that is not complete, so the file has to prove the house exists, is legal to occupy, and has a supportable value.
1. Prove the home is finished and legal. The lender wants a certificate of occupancy or the local equivalent. An archived HUD guide to new-construction appraisals shows the kind of trail involved: builder certification, a building permit, and a certificate of occupancy or equivalent. That guide is specific to FHA loans. It does not govern these lines, but it shows what a clean completion file looks like. Final inspection sign-offs belong in the file too.
2. Clear title and vesting. Title must be fee simple or leasehold, held by you or your revocable living trust. If the house is already deeded to an LLC, you need a vesting change or a different product.
3. Establish the lien position. A cash-funded build leaves a clean first-lien position. If a construction loan paid for the build, it must be paid off or converted first, or the new line sits second behind it. The network writes standalone lines in first or second position.
4. Order the valuation. Lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV can trigger a secondary valuation. Every line above $500,000 needs a full appraisal. You can request a full appraisal on any line, and on a custom home that is usually the smarter move.
5. Review credit and debts. The score model is single-bureau and keyed to the primary wage earner. The report can be no more than 90 days old at closing. Housing history and tradelines are checked against the program’s standards.
6. Review the property type. Single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Modular factory-built homes are eligible on the longer-runway program only. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.
7. Close and draw. At least 75% of the line is drawn at closing. Later draws start at a $1,000 minimum, with a higher minimum in Texas.
What Structures Exist?
Two wholesale structures sit behind the network’s primary and second-home lines. The longer-runway program has a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Tennessee shortens both. Investment lines run the 5-year draw and 25-year repayment structure only. The line is variable and never converts to fixed.
A quote always carries its own program’s draw and repayment structure. Where the programs differ, each figure applies only inside its own program.
Per the Consumer Financial Protection Bureau, a HELOC is an open-end line of credit secured by home equity, and the draw period can run 10 years, for example. The same source notes that a lender may restrict further credit if the home’s value falls significantly. That risk is higher on a custom home with few comparables.
For an owner-built house, a HELOC is not the only route. Here is how the options compare.
| Route | Best fit | Title holder | Leverage note |
|---|---|---|---|
| Standalone HELOC | Finished home, existing equity | Individual or revocable trust | Up to 70% CLTV, investment |
| DSCR cash-out refinance | Finished rental | Individual or entity | About 75% LTV, standard rentals |
| Construction-to-permanent | Build in progress | Individual | Sized to cost and value |
Key Terms Defined
Certificate of occupancy: The local sign-off that a finished building meets code and may be lived in.
CLTV: Combined loan-to-value, which is every lien on the property added together and divided by its value.
Draw period: The stretch of time when you can borrow from the line, with interest-only payments.
Repayment period: The stretch after the draw, when the balance amortizes fully.
First lien and second lien: The order in which loans get repaid if the property is sold, with first paid before second.
Vesting: How title is held, such as an individual, a revocable trust, or an LLC.
Seasoning: The ownership or completion time a lender wants to see before it will lend against the property.
Where Does the General Rule Break?
The general rule is simple: finished home, clean title, supportable value. Several owner-built situations bend it.
The build is still going. No equity exists yet, so no HELOC fits. A construction loan or construction-to-permanent loan is the right tool, and a line can follow once the home is complete.
The home was built with a construction loan. The line has to wait until that loan is paid off or converted, or it takes second position. Lenders also differ on whether any seasoning clock starts at land purchase or at completion. Ask each program how it counts.
The work was not permitted. Missing permits or final sign-offs stall the file. Fix the paper trail with the local building department before you apply.
The land is agricultural or the house is a barndominium. Agricultural zoning is not eligible. Manufactured homes and log homes are not eligible either. A barn-style build often fails on zoning or construction type before credit even matters.
The house is large, rural, or unusual. Thin comparable sales make an automated value unreliable. Request a full appraisal early, and gather cost records to show how the build fits local values. An appraiser relies on comparable sales, so overbuilding for the area does not create equity.
The house is already in an LLC. These lines cannot close in an LLC, a corporation, a partnership, or an irrevocable, blind, or land trust. Moving title takes time and may have its own consequences. A DSCR cash-out refinance is the usual alternative.
State rules layer on top. A few states apply their own overlays, such as homestead limits, acreage caps, and rules on recently listed properties. Check your state before you settle on a structure.
The borrower is short on credit. Profiles below 640 are limited to single-family residences with a clean 12-month housing history under the longer-runway program. That restriction reaches primary residences only. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history splits by program. One program seasons a foreclosure at 7 years and a deed-in-lieu, pre-foreclosure, or short sale at 4. The other declines the history entirely, regardless of age.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
When Does a DSCR Cash-Out Beat a HELOC on an Owner-Built Rental?
If the house is a rental, a DSCR cash-out refinance often fits better than a line. It lets you pull equity from a finished rental without personal-income documentation, because the file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The numbers also work at higher leverage. Most cash-out files across the network top out around 75% LTV on standard rentals, and about 6 months of seasoning is the common expectation. Compare that with the 70% CLTV ceiling on an investment HELOC.
Entity ownership is the other difference. DSCR files can close in an LLC, subject to lender program eligibility. Equity lines cannot. If you built the house inside an entity, that settles the question.
DSCR is not a cash-flow test. It compares rent to the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capital spending sit outside the calculation. Select programs start at 1.00. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better terms.
Credit works differently here too. A 620 floor exists in parts of the network, most programs want around 660, and 700 or better opens the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Reserves vary by lender and file, commonly around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans step up to about 9 months. Ineligible types such as manufactured homes, log homes, and barndominiums fall outside the DSCR programs too.

What Does a Worked Example Look Like?
Run it as a modeled scenario, not a quote. Picture a borrower who built a single-family rental with cash. The home has its certificate of occupancy, sits in the borrower’s own name, and carries no mortgage. The borrower holds a 740 credit profile.
The home is an investment property, so the line tops out at 70% CLTV. With no other lien, the new line is the only debt, and the full 70% is available in principle. A full appraisal sets the value, because an automated value on a custom home can come in light. If the appraisal lands below build cost, the line shrinks with it. Cost is not value.
Now say the same borrower wants more than 70% leverage, or holds title in an LLC. A DSCR cash-out refinance at up to about 75% LTV on a standard rental becomes the stronger candidate, if rent covers the full monthly obligation at roughly 1.2x. If the rent only covers it near 1.0x, leverage and terms may tighten. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Now flip the occupancy. The same house as a primary residence at 740 can reach 90% CLTV up to $500,000, because 720 or better unlocks the top tier. Occupancy alone moves the ceiling by 20 points of CLTV.
Why Do Owner-Built Files Get Denied, and How Do You Fix Them?
Most denials trace back to a gap in the paper, not a weak borrower. The common ones:
- No certificate of occupancy or open permits. Close them out with the local building department and add the final sign-offs to the file.
- Value does not support the line. Order a full appraisal, bring cost records and recent in-area sales, and request a reconsideration if the first value comes in low.
- Wrong vesting. Move title to yourself or a revocable trust before applying, or switch to a DSCR cash-out if the entity must stay.
- Open construction loan. Pay it off or refinance it into permanent financing first, or accept a second-lien position.
- Occupancy mismatch. If the house is a rental, apply as an investment property. A rental treated as a primary residence is a problem for the file, not a shortcut.
- Credit or housing-history gaps. Check tradelines and mortgage history before the report is pulled. A report older than 90 days at closing must be redone, and rescores are not allowed.
What Does the Decision Look Like in Practice?
Sort the house first. If it is unfinished, the answer is construction financing. If it is finished and owner-occupied, a primary-residence line gives the most room at 720 or better. If it is a second home, the ceiling is similar but the credit floor is 640. If it is a rental, a line caps at 70% CLTV, and a DSCR cash-out often gives more leverage and entity flexibility.

Frequently Asked Questions
Can I get a HELOC while the house is still being built?
Not in any practical sense. A line is secured by equity in a finished, valued home, and an unfinished structure has no measurable equity. Construction loans fund in stages against cost and expected value, then convert or get replaced when the build ends. Once the house has its certificate of occupancy, a line becomes possible.
Does acting as my own general contractor hurt approval?
Not by itself. The lender cares about the finished product: permits, final inspections, a certificate of occupancy, clean title, and a supportable value. Documentation is the difference. A well-kept file of permits, inspection sign-offs, and cost records helps the valuation and shortens the questions.
Will I need a full appraisal?
Lines at or below $500,000 ordinarily use an automated valuation, but a higher CLTV may call for a secondary valuation. Every line above $500,000 requires a full appraisal, and you may request one on any line. On a one-of-a-kind home with few comparable sales, a full appraisal is often the safer choice.
Can an LLC borrow on these lines?
No. Title must be held by the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already in an LLC needs a vesting change, or a DSCR cash-out refinance instead.
Is a HELOC or a cash-out refinance better on an owner-built rental?
It depends on leverage, vesting, and how you document income. An investment line on this network tops out at 70% CLTV and needs individual or trust title. A DSCR cash-out reaches about 75% LTV on standard rentals and can close in an entity, subject to lender program eligibility. If the rent does not cover the full payment at the coverage a program wants, leverage and terms adjust. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
