Current DSCR HELOC guidelines, updated from one source.
The figures below are the second-lien tier of the program, the line written behind a first mortgage the owner keeps, read from Lendmire’s centralized guideline source and refreshed on this page as the wholesale program changes: the combined loan-to-value ceiling, the credit score to start, the line sizes, and the draw and repayment periods.
Of the rental’s value, first mortgage included
Total liens on the rental, the first mortgage plus the new line, may reach 70% of value behind a first mortgage you keep; the ladder below shows the first-lien tiers on a paid-off rental, which run to 75% at the top tier.
Credit score for a second-lien line
A second-lien line starts at a 720 credit profile; a first-lien line on a paid-off rental opens at 700. The tiers above the floor open more leverage, and the largest first-lien lines carry a reduced ceiling of their own.
Automated valuation on lines to $400,000
Lines run from $50,000 to $500,000 on a second lien and to $1,000,000 on a first lien; an automated valuation with an inspection covers lines to $400,000 in either position, and every larger line takes a full interior appraisal.
Interest-only, then 25 years of repayment
Draw for 5 years on interest-only payments, then repay over 25 years on a fully amortizing schedule, a 30-year maturity. At least 80% of the line, and $50,000, funds at closing.
| Credit profile | Max combined LTV | Max line | Lien position · valuation |
|---|---|---|---|
| 740+ | 70% | $500,000 | Second lien behind the first mortgage · Automated valuation + inspection to $400,000, full interior appraisal above |
| 720+ | 70% | $500,000 | Second lien behind the first mortgage · Automated valuation + inspection to $400,000, full interior appraisal above |
| 740+ | 75% | $500,000 | First lien on a paid-off rental · Automated valuation + inspection to $400,000, full interior appraisal above |
| 720+ | 70% | $500,000 | First lien on a paid-off rental · Automated valuation + inspection to $400,000, full interior appraisal above |
| 720+ | 65% | $750,000 | First lien on a paid-off rental · Automated valuation + inspection to $400,000, full interior appraisal above |
| 720+ | 65% | $1,000,000 | First lien on a paid-off rental · Automated valuation + inspection to $400,000, full interior appraisal above |
| 700+ | 70% | $500,000 | First lien on a paid-off rental · Automated valuation + inspection to $400,000, full interior appraisal above |
The 70% combined loan-to-value ceiling behind a first mortgage requires a 720 credit profile. A first-lien line on a paid-off rental starts at a 700 profile, reaches 75% loan-to-value at the top tier, and runs to $1,000,000 at 65% on lines above $500,000. The rent must cover the qualifying payment at 1.10 or better.

Program parameters shown on this page are wholesale lender guidelines read from Lendmire’s centralized guideline source, subject to change without notice and to full underwriting; they are not an offer, a quote, or a commitment to lend. The line amount, combined loan-to-value, coverage test, and eligibility depend on the valuation, the lease and the rent, the credit profile, the vesting, the property, and the lender’s own calculation. No rate, index, payment, or fee is stated on this page; terms are provided in writing by a licensed loan officer.

What a DSCR HELOC is — and how the rent sizes the line.
A DSCR HELOC is a revolving lien on a rental, usually in second position: the property secures it, the rent qualifies it, and the balance moves as you draw and repay. The pieces that decide the line in San Mateo are the rental’s value, the balance already on it, the credit tier, and a rent that covers the line.
For the program overview, see Lendmire’s DSCR HELOC program, or the statewide guide at DSCR HELOC in California.
A line on the rental, behind the mortgage you keep
A DSCR HELOC is revolving credit secured by the rental: you draw what you need during the draw period, pay interest only on what is outstanding, and the balance comes down as you repay. After the draw period the line closes to new draws and the balance repays on an amortizing schedule.
The rent qualifies the line, not your tax returns
Coverage is the income test. A San Mateo rental whose rent covers the qualifying payment at the program minimum passes it whatever the owner’s tax returns show, and the tier, the value, the seasoning, and the property list still apply; a rental whose rent falls short does not pass, however strong the owner’s income, because that income is never in the file.
Your credit tier sets the ceiling and the cap
Every tier the program offers is at or above the score at which its tradeline-depth rules are waived, so the tier sets the ceiling and the cap rather than the depth of the credit file. A San Mateo investor with a thin personal credit file and a strong rental is still read on the score first and the rent second.
Valuation, the lease, the LLC, and closing
Seasoning matters on a rental: a property bought or refinanced inside the program’s seasoning window waits, and ownership must season before the line closes. A San Mateo rental listed for sale in the months before the application is not eligible, and a declining-market flag on the valuation trims the ceiling.
Two things set the line: how much room is under the ceiling for your tier and position, and how large a line the rent will carry. The calculator sizes the first from the value, the balance, and the tier; the lender settles the second from the lease and the qualifying payment.
San Mateo’s rental equity in figures — and how a line fits it.
Before the calculator, the market: what a typical San Mateo property is worth and how much of the city owns. A rental bought years ago in a market like this one usually carries the equity a line is written against; a recent purchase at the median may not.
Market context only. Market figures explain the typical file, not yours. A San Mateo rental held for a decade in a market like this usually carries far more equity than the median suggests; one bought last year at the median usually carries less than the ceiling allows.

Distinct San Mateo rental neighborhoods, distinct equity pictures.
Neighborhood by neighborhood, San Mateo’s rentals present different files: some with deep equity and modest rents, some with high rents and thin equity, some with valuation questions of their own. The cards below walk through them.
Two-to-four-unit buildings
A San Mateo fourplex brings several leases to the coverage test, so the equity, the tier, and the cap are often the binding limits instead. The leases for the occupied units document the rent, and the valuation uses the multi-unit form on the larger lines. San Mateo is home to about 103K people and sits within the San Francisco-Oakland-Fremont, CA area.
Entity-held portfolios
A San Mateo investor with several entity-held rentals opens lines without restructuring; the program reads each property on its own value, balance, lease, and tier, and the borrower’s exposure across the program is counted as the lines add up. On a one-unit rental at San Mateo’s median home value, the second-lien ceiling puts total liens near $1,133,090 — the line is what remains after the first mortgage balance, and the rent must cover the qualifying payment; a paid-off rental on a first-lien line sits above the second-lien ceiling.
Condominium rentals
Condominiums are a large share of San Mateo’s rental stock, and a line on one is routine: a warrantable project takes the condominium ceiling, a non-warrantable one the reduced ceiling, and the association’s dues and any assessment travel with the file. The rent test reads the unit’s lease like any other. Median household income in San Mateo sits near $153,504 on the latest Census estimate.
Established close-in rentals
The close-in San Mateo neighborhoods hold rentals bought a decade or more ago, and those files carry the deepest equity: a small first mortgage, a value that has run far ahead of it, and room under the ceiling that the rent, not the equity, usually caps. The median owner-occupied home value in San Mateo runs near $1,618,700 on the latest Census estimate.
Newer infill and recent purchases
Infill purchases in San Mateo are the files where the scenario review most often says wait: the equity is not there yet or the seasoning window has not closed. The line is a seasoned-property product, and these properties season on their own schedule. About 50% of San Mateo’s households rent — roughly 19,985 renter households on the latest Census estimate.
High-value rentals
At the top of San Mateo’s rental values the binding limit is the program’s maximum line, not the ceiling. The file takes a full appraisal above the valuation threshold, and the first-lien column offers the larger cap when there is no mortgage ahead. Roughly 19,910 San Mateo households own their homes on the latest Census estimate — 50% of all households, the pool a rental equity line is written for.
The patterns above are market observations drawn from the housing stock and the Census figures, not program rules. Every San Mateo rental is read on its own valuation, its own lease, and its own tier.
Four ways San Mateo landlords put a rental equity line to work.
From the next purchase to the next repair, a rental equity line answers needs that arrive on their own schedule. The four uses below are the ones San Mateo landlords bring most often; the line is sized by equity and rent, not by the use.
Rehab and repairs staged over months
Rehab is a classic use of a line: the budget is uncertain until the walls are open, and a revolving line absorbs the uncertainty better than a fixed lump sum. Interest accrues only on what is drawn during the draw period.
Finish a value-add before the permanent loan
An investor who bought a San Mateo rental to improve and refinance can finish the work on a line secured by another rental’s equity, then refinance the improved property on its new value. The line is repaid from the refinance and stays open for the next project.
Fund the next purchase without refinancing
The down payment on the next San Mateo rental is the classic use: draw it from the line when the contract is signed, keep the first mortgage on the property that secures the line, and let the new property carry its own loan. A paid-off rental can fund more than one.
Bridge a sale, a tax bill, or a buyout
A line bridges the gaps a portfolio produces: a partner’s buyout, a property-tax bill that lands before a sale closes, a deposit due before another rental refinances. A San Mateo owner draws, closes the gap, and repays when the money arrives.
Estimate your San Mateo rental’s available credit line before requesting a quote.
Equity is the first gate and rent is the second. This calculator runs the first: value, balance, tier, and lien position against the current program tables for San Mateo. The second, whether the rent covers the qualifying payment at the program minimum, is the lender’s call from the lease and the appraiser’s rent schedule.

Illustrative starting assumptions: a $1,620,000 rental value near San Mateo’s median owner-occupied home value and a $730,000 modeled remaining first-mortgage balance (U.S. Census Bureau). Combined loan-to-value ceilings and line caps follow the current program tables for the lien position and credit tier selected and update from Lendmire’s centralized guideline source on the live page. The rent test is the lender’s: the gross rent must cover the qualifying payment on the whole line at the program’s coverage minimum. Every field is editable.
Illustrative estimate only — not a credit decision, approval, quote, or commitment to lend. The actual line amount, combined loan-to-value, and eligibility depend on the automated valuation or appraisal, the lease and the rent, the credit profile, the vesting, documentation, and full underwriting by the selected wholesale lender; the rate, the payment, and any costs are provided in writing by a licensed loan officer. Minimum score, line-size, coverage, and draw requirements follow the current program snapshot shown on this page. Licensed in sixteen states for consumer mortgages.
Same rental equity, four very different ways to reach it.
The same San Mateo rental can reach its equity four ways, and they differ in what qualifies the borrower and what happens to the first mortgage. A DSCR HELOC qualifies on the rent and leaves the first mortgage alone; the other three read the owner’s income, the owner’s deposits, or replace the mortgage outright.
A rent-qualified line, an income-qualified line, a cash-out refinance, or a bank statement line.
The route when the owner’s income is the problem and the rental’s income is not: the lease and the market rent carry the line, the entity stays on title, and nothing about the first mortgage changes. It caps lower than the income-qualified line and starts at a stronger credit tier.
For the San Mateo landlord with clean tax returns, room in the debt ratio, and a rental titled in their own name. The income-qualified line is the higher-leverage route; the DSCR HELOC is the route when the returns, the ratio, or the LLC make that file impossible. For the income-qualified route, see Lendmire’s investment property HELOC.
A DSCR cash-out refinance replaces the first mortgage with a larger one and hands over the difference as a lump sum, qualified on the rent like the line. It reaches more of the equity in one closing, at the cost of the existing rate and a new thirty-year loan on the whole balance. For the refinance route, see the investment property cash-out refinance.
For the San Mateo self-employed owner whose business deposits tell a better story than the returns, on a property held personally. Where the rental’s own rent covers the line, the DSCR HELOC asks for less; where it does not, the bank statement line reads the owner instead. For the deposit-qualified route, see the bank statement HELOC.
What to prepare for a San Mateo scenario review.
The file reads the property and the credit report. Gather these before the scenario review, and the prequalification has what it needs; nothing on the list is a tax return.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the lease, the entity, the property, the lien position, and the credit profile. Nothing here is legal or tax advice.
Local details that can change the line.
Before relying on a figure, read these. They are the places a San Mateo rental line differs from the clean example in the calculator, and each carries a check to run first.
Use these checks to keep the San Mateo file clean and fundable.
Think of the details in two groups. Some size the line: the tier, the valuation, the lien position, the rent. Others decide eligibility outright: the property type, the seasoning, a recent listing, a solar lien, the entity papers. A San Mateo file clears the second group before the first matters.
- Confirm the vesting: Which title holders and first-mortgage borrowers will sign as non-borrowing owners.
- Confirm the dates: The date of the most recent purchase or refinance of the property, note date to note date.
- Confirm the valuation path: What comparable sales in the San Mateo submarket support, before relying on a listing-based estimate.
Title in your name or your LLC
A trust on title is a different question from an entity on title: a land trust is on the program’s ineligible list, and a revocable trust is read by the lender case by case. A San Mateo rental in an LLC is written in the LLC’s name; a rental in a land trust is not written at all.
The seasoning clock on purchases and refinances
A rental bought or refinanced inside the program’s seasoning window is not eligible yet, measured note date to note date, and ownership seasons on its own clock from the purchase settlement. A San Mateo investor who closed this spring plans the line for after the window.
The valuation sets the value the ceiling applies to
Lines to the valuation threshold use an automated model plus a property inspection report; larger lines take a full interior appraisal. A model that misses the program’s confidence standard sends the file to a full interior appraisal, and a San Mateo value estimated from listings can land lower on either path.
The closing draw and the later draws
Most of the line funds at closing, and the closing draw has a floor of its own; the line is not opened empty as a reserve. A San Mateo owner who wants a standing reserve sizes the line for the amount that will actually be drawn, since interest accrues on the drawn balance from closing.
A recent listing, a solar lien, a declining market
A declining-market designation on the valuation trims the ceiling by a set number of points, a listing inside the program’s window makes the rental ineligible until the window passes, and a solar lien on title stops the closing until it is cleared. Each is the appraiser’s or the title company’s call, and a San Mateo file near the ceiling can lose the top of the line to the first of them.
From a San Mateo rental prequalification to a funded line.
A DSCR HELOC on a San Mateo rental moves in four steps, and the first two are conversations. The scenario review sizes the line on the value, the balance, the tier, and the rent; the prequalification confirms it; verification and valuation prove it; closing funds it.
Scenario review
Before any application, the scenario is read against the program: lien position, tier, valuation path, seasoning, the property list, and the entity. A San Mateo owner leaves the review knowing the line the tables support and the gates the file must clear.
Prequalification
With the credit report in hand the tier is fixed, and with the lease in hand the rent test is run. A San Mateo prequalification settles the two gates that size the line and lists what the valuation and the title search will confirm.
Verification and valuation
This is the step the owner does not control: the valuation lands where the comparables put it, and the title search shows what is recorded. A San Mateo file whose value or lease comes in under the estimate is re-sized here, not declined, unless a gate fails.
Closing and funding
At closing the line is recorded against the rental, in the entity’s name when an LLC holds title, and the minimum draw funds. The first mortgage is untouched, the draw period begins, and later draws follow the program’s minimum.
A brokerage that matches the line to the rental.
What Lendmire brings to a San Mateo rental line is comparison and placement: the rent-qualified line beside its alternatives, the tier read against every column, and the file placed with the wholesale lender whose program writes it.
Four routes, the right one quoted
Every San Mateo rental file is read against the DSCR HELOC, the investment-property HELOC, the DSCR cash-out refinance, and the bank statement HELOC. The ceiling, the floor, the paperwork, and what happens to the first mortgage are compared before an offer is written.
The entity stays on title
Landlords who built a portfolio inside entities for liability reasons should not have to unwind it for a line. The DSCR HELOC is placed through a wholesale program that writes the entity, and Lendmire’s San Mateo review starts with the deed as it is.
Licensed, in writing, the lender never named
Lendmire is the broker, not the lender. The program is placed with select lenders in the wholesale network; the figures on this page are program parameters subject to underwriting, and the rate and the payment on a San Mateo line are quoted in writing, never on a web page.

San Mateo DSCR HELOC FAQs
The questions San Mateo landlords ask before a rent-qualified line, answered from the program as it stands; figures live in the snapshot above.
What is a DSCR HELOC?
It is the DSCR idea applied to a line of credit: the rental qualifies itself. A San Mateo landlord keeps the first mortgage, opens a revolving line behind it sized by value, balance, and credit tier, and proves only that the rent covers the line’s qualifying payment. Vesting in an entity is allowed.
Can the rental stay in my LLC?
Yes. Vesting in a limited liability company is allowed on investment property, and the line is recorded in the entity’s name with the members as guarantors. The entity’s articles, operating agreement, and good standing go in the file, and a member on title who is not a borrower signs a non-borrowing owner acknowledgment. The deed does not move.
How is the rent test calculated?
The property’s gross rent is set against a stressed, fully amortizing payment on the full line, and the ratio must reach the coverage minimum in the snapshot. Nothing about the owner’s income enters the calculation; a San Mateo landlord with no tax returns at all qualifies if the rent does.
Is an appraisal required?
Lines to the valuation threshold shown in the snapshot use an automated valuation plus a property inspection report, or a full interior appraisal; lines above it require a full interior appraisal. Appraisal waivers are not accepted, and a model that misses the program’s confidence standard sends the file to a full interior appraisal.
How do the draw period and repayment work?
Interest-only through the draw period on the drawn balance, fully amortizing through the repayment period after. The closing draw is set by the program, the later draws have a floor, and the rate is variable throughout; a San Mateo owner plans the line around the shift in payment when the draw period ends.
Do I need tax returns or W-2s?
No personal income documents of any kind. That is the difference between this line and the investment-property HELOC, which qualifies on the owner’s returns and ratio. On a San Mateo DSCR HELOC the property’s rent does the qualifying.
Is there a minimum line or a minimum draw?
A minimum line applies, and most of the approved line funds at closing by program rule. Later draws are at least the program minimum. Size the line to the amount you will use within the draw period, not to the largest figure the tables allow.
Do I need reserves or cash to close?
No reserves and no cash to close. That is part of the program’s appeal to a landlord whose cash is in the properties rather than the bank: the equity and the rent carry the file, and nothing is held back as a reserve requirement.
Can the line be a first lien on a paid-off rental?
A first-lien DSCR HELOC on a paid-off rental is on the program. The San Mateo owner who paid a rental off, or inherited one free of debt, opens a line against it without a mortgage ahead; the ladder’s first-lien rows show the ceiling and cap by tier.
Can I open a line if the rental was recently listed for sale?
Only after the window has passed. The program does not write a line on a property listed within the months before the application; a San Mateo landlord who listed and withdrew waits for the window, then applies.
Your San Mateo, CA rental can qualify itself.
In a short scenario review the rental’s equity, rent, and entity are read against the program: ceiling, cap, lien position, rent test. You leave with a line amount and a short list, not an application.
