The Quick Read: Open a home equity line sized to the project, pay contractors from it, finish and lease the unit, then pay off and close the full line balance from a DSCR cash-out refinance sized on the new appraised value. Plan the exit before the line closes, not after the last invoice. The refinance cash depends on what the appraiser says, not on what the rehab cost.
- The line is underwritten on the borrower. The DSCR exit is underwritten on the property’s rent.
- On an investment property, the network’s home equity lines cap at 70% combined loan-to-value and $500,000 total.
- A standard rental cash-out refinance tops out around 75% LTV, with about 6 months of seasoning as the common expectation.
- The line must be paid off and formally closed, or subordinated, at the refinance. A zero balance alone is not enough. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Most of the trouble in this strategy comes from the middle of the file, not the ends. The line gets opened, the work gets done, and then the refinance lender finds a value that is lower than planned, a lien that is still on title, or coverage that thins out once the larger loan is added. The sections below follow the money from the line’s closing to payoff and flag where each step tends to stall.
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.
What This Strategy Is, and What It Isn’t
A rental rehab line is short-term bridge capital. The investor borrows against equity, spends it on repairs, and plans to retire the balance with a refinance once the property is worth more and is leased.
It is two ordinary products used in sequence. One is a home equity line of credit, which revolves. The other is a DSCR cash-out refinance, which replaces the existing first mortgage and pays off whatever sits behind it.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
The strategy is not a guarantee that the refinance returns what you spent. It also isn’t a way to avoid a credit review on the line itself. And clearing a 1.00 coverage ratio at the exit does not mean the property cash flows. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital reserves sit outside the calculation.
Key Terms Defined
HELOC: A revolving credit line secured by real estate, where the borrower draws, repays, and draws again during a set draw period.
After-repair value (ARV): The projected value of the property once the rehab is done. It is a plan, not an appraisal.
Seasoning: The ownership time a refinance lender wants before it sizes a loan on appraised value instead of cost.
Combined loan-to-value (CLTV): All liens on the property added together and divided by its value.
Subordination: An agreement in which the line lender lets a new first mortgage take priority over the line.
PITIA: Principal, interest, taxes, insurance, and any association dues. It is the denominator of the DSCR calculation.
Which Property Should Secure the Line?
The line can sit on the investor’s primary home or on the rental itself. Each choice puts a different asset at risk and creates a different cleanup job at the refinance.
| Factor | Line on primary home | Line on the rental |
|---|---|---|
| Asset at risk | The residence | The rental |
| Lien at refinance | Separate property, still needs a release | Junior lien that must be cleared |
| Lender pool | Wider | Narrower |
| Title | Individual or trust | Individual or trust |
On an investment property, the network’s home equity lines are limited to 70% CLTV and a $500,000 maximum line. The minimum credit score is 700, and scores above that buy eligibility rather than extra leverage. These lines are available only in Lendmire’s 16 full-service states, which is narrower than the DSCR footprint. Figures are subject to lender guidelines and a full file review.
Three structural points matter for a rehab budget:
- Draw structure. Investment lines run a 5-year interest-only draw followed by a 25-year repayment. Pricing floats through both periods and never converts to fixed.
- Day-one balance. At least 75% of the line is drawn at closing, so this is not a pay-as-invoices-arrive facility. Interest runs on most of the line from the start. Size the line to the project, not to the maximum.
- Valuation. Because an investment line cannot exceed $500,000, it is normally valued by automated valuation with no traditional appraisal. That as-is value is the pre-rehab number, so it understates what the finished property may be worth.
The borrower also has to qualify personally. The maximum debt-to-income ratio is 50%, calculated on the interest-only payment at the full draw. A borrower with more than three lines, or with more than 15 financed properties, is not eligible.
Design the Exit Before the Line Closes
Work backward from the payoff. The new refinance has to retire three things: the existing first mortgage, the line balance, and the closing costs. Whatever is left is your cash back.
The refinance lender orders its own appraisal. Cash-out on a standard rental tops out around 75% LTV across most of the network, so the formula is simple: appraised value times the LTV cap, minus the first mortgage, minus the line balance, minus closing costs. If the result is thin or negative, the budget is too large for the value it creates. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A rehab budget should therefore follow what may support a higher appraised value or a stronger rent, depending on comps and underwriter review. Roof, kitchen, bath, flooring, HVAC, and code work often fit. Deferred maintenance that the appraiser treats as condition, not value, may return little.
Short-term rental collateral is different. A cash-out refinance on a short-term rental tops out at 70% LTV, expects a 640+ score and about 12 months of hosting history, and carries a 1.00 coverage floor on refinances. The same planning math applies, with a lower cap. Every figure here varies by lender and program.
The Timeline, Stage by Stage
The line carries interest the whole way. The stage that surprises people is the gap between finished work and a closed refinance.
| Stage | What happens | Line status |
|---|---|---|
| Opening | Credit, DTI, valuation, title | Mostly drawn at closing |
| Rehab | Contractor invoices paid | Interest accrues on the balance |
| Lease-up | Unit rented, lease signed | Interest and carry continue |
| Seasoning | Ownership time clears | Line still open |
| Appraisal | New value set | Payoff amount fixed |
| Refinance | Line paid and released | Closed or subordinated |
Carry cost is real money that no one budgets. Interest on the line, taxes, insurance, utilities, and vacancy all keep running until the new loan funds. Build those into the project cost before the line closes, not after the unit is already empty.
Seasoning is the main clock. About 6 months is the common expectation for a cash-out. On many files it runs from the date title was recorded in the borrower’s name, not from the day the rehab finished or the lease started. Lenders differ, so confirm the starting point before building a schedule around it.
Worked Example: Three Outcomes
These are modeled assumptions, not market data. Express everything as a percentage of the planned after-repair value, which is set at 100. The existing first mortgage is 40, and the rehab draw on the line is 20, so the total to retire is 60. The new loan is a cash-out on a standard rental at 75% LTV, before closing costs. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
| Scenario | Appraised value | New loan | Left after payoff |
|---|---|---|---|
| Clean exit | 100 | 75 | 15 |
| Light appraisal | 90 | 67.5 | 7.5 |
| Low appraisal | 80 | 60 | 0 |
In the clean exit, the new loan retires the first mortgage and the line, and the 15 left over is cash back. That is less than the 20 spent on the rehab, so the strategy returns part of the spend, not all of it. The rest stays as equity in the property. The light appraisal still pays off both liens, but closing costs eat most of the 7.5 that remains. The low appraisal retires the first mortgage and the line and leaves no cushion, so closing costs come out of the borrower’s pocket.
Coverage moves too. A larger new loan means a larger payment, and the DSCR is monthly rent divided by that full PITIA. A property that cleared comfortably on the old mortgage may sit closer to the floor on the new one. That is why the rent has to be tested against the refinance payment, not the old one.
A low appraisal leaves four options: bring cash to closing, take a smaller loan, wait and reappraise, or challenge the value. A challenge needs a reconsideration packet with recent in-neighborhood sales, condition adjustments, and the rehab invoices. A smaller loan leaves less after the payoff.
How the Refinance Lender Clears the Line
A new first mortgage will not close with a revolving line sitting in front of it. Liens rank by recording date, so when a refinance pays off the first mortgage, a line recorded behind it can move up to first position. The refinance lender’s title work will find it.
Bills.com explains that the line lender can be asked to subordinate, and that if it refuses, the usual exits are to pay off and close the line or to roll the balance into a cash-out refinance. Three outcomes follow:
1. Pay off and close from proceeds. This is the cleanest path. The settlement statement shows the payoff, and the line is closed.
2. Subordinate. The line lender consents, and the line stays open behind the new first. It adds a consent step and keeps a junior lien on title.
3. Pay down to zero without closing. The line remains on title. Get a payoff letter and a recorded lien release.
Documents to line up before applying include the lease, rent history, contractor invoices with proof of payment, the line payoff letter, and the settlement statement from the original purchase. A cost-basis record matters most if the refinance sizes on cost rather than value.
What the DSCR Exit Requires
The exit is a separate underwriting. Most files land around 75% LTV on a standard rental cash-out. Credit floors vary. A 620 floor exists in parts of the network, most programs want around 660, and 700+ 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, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA, and loans above $1,500,000 typically step up to about 9 months. Documentation of those reserves is one of the quiet reasons these files get kicked back.
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better leverage. Qualification is subject to lender guidelines, credit approval, and property review. Read Lendmire’s complete DSCR loans guide for the full framework behind these numbers.
The structure options give some room. The spine is the 30-year fixed. Extended terms and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed structures. Property types such as manufactured homes, log homes, and barndominiums are not offered.
Where the General Rule Breaks
LLC-owned rentals. The network’s home equity lines require title in an individual’s name or a revocable living trust. An LLC, a corporation, or an irrevocable trust cannot hold title. A rental already deeded to an LLC needs a vesting change, which gives up the entity’s liability separation, or a different tool. A DSCR cash-out can leave the LLC on title, subject to lender program eligibility.
Variable pricing. Home equity line pricing is typically variable, and payments generally rise when the draw period ends and principal repayment begins, as ConsumerAffairs describes. A long rehab, a slow lease-up, and a seasoning wait all raise the carrying cost.
Collateral risk. The CFPB HELOC booklet explains that many lenders set the limit as a percentage of appraised value minus the existing mortgage balance. It also warns that missed payments can put the home at risk. When the line sits on a primary residence, a stalled rental refinance puts the residence in play.
Line freezes. Home equity plans generally allow a lender to freeze or reduce a line if home value falls. A rehab funded by a revolving line can lose its remaining draws mid-project. Keep a cash buffer for that case.
An early exit. Inside the seasoning window, a lender that will close usually sizes on cost basis, which often leaves the line not paid in full. Some lines also charge a fee for early payoff or closure, so read the payoff terms.
Delayed financing. This is an agency concept that waives seasoning on a cash purchase. It does not waive the coverage test, and it returns roughly the documented cost, not ARV. A hard-money lien on the purchase usually disqualifies it. On DSCR files it is set by the individual lender.
When Not to Use This Strategy
Skip it when the margin between the planned value and the full payoff is thin. A rehab that depends on a perfect appraisal has no room for a light one.
Skip it when the line would sit on the home you live in and you have no cash buffer. Skip it when the property sits in an LLC you want to keep. Skip it when the unit will not lease promptly, since the carry cost grows without any matching income.
Using a line for a down payment on a buy-and-hold deal is a related trap. It finances close to the whole deal and usually hurts cash flow, so the plan to repay the line has to be written down before the line closes.
What the Decision Looks Like in Practice
Compare the line against the other tools on three points: cost of carry, personal debt-to-income, and the exit. A line uses personal DTI. A DSCR exit does not. A smaller line leaves a favorable first mortgage in place, while a cash-out replaces it. Lendmire’s piece How Much a Standing Rental HELOC Releases at the Combined LTV Cap covers the sizing side, and its comparison of a smaller HELOC against a larger cash-out refinance covers the tradeoff once the project is bigger.
Before the line closes, confirm five things: how title is held, the as-is value against the planned value, the total budget plus a buffer, reserves documentation for the exit, and how the line will be released. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
If you are weighing a home equity line against a cash-out refinance and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals.
Frequently Asked Questions
Can I refinance if a HELOC is still on the property?
Yes, but the line has to be dealt with. The refinance can pay it off and close it, or the line lender can agree to subordinate. A zero balance does not remove the lien until the line is formally closed and released.
How long do I wait before refinancing after the rehab?
The common expectation is about 6 months of seasoning, and on many files the clock runs from recorded title. Finishing the work or signing a lease does not restart or complete it. Inside that window a lender may size on cost basis instead of value.
What happens if the appraisal comes in low?
The cash-out shrinks, because it is value times the LTV cap minus the payoffs. You can bring cash, take a smaller loan, wait and reappraise, or submit a reconsideration packet with comps and rehab documentation. A smaller loan leaves less cash after the line payoff.
Should I secure the line on my home or the rental?
A line on the home puts the residence at risk, while a line on the rental creates a junior lien to clear at the refinance. On an investment property, the network’s lines cap at 70% CLTV and $500,000, and title must be in an individual or revocable trust.
Does the line payment affect my DSCR approval?
The line does not enter the property ratio, but the new larger loan does. Rent is divided by the full PITIA on the new loan, so a bigger payoff lowers coverage. Test the rent against the refinance payment before you start.
