Most people who own a rental find out the rules the hard way. They call about a refinance, get quoted a number, and learn later that the number applied to a primary residence. Investment property is its own lane, with its own loan-to-value ceilings and reserve math, and almost none of it is posted where a normal person would look.
That is not your fault. The guidelines governing a conventional refinance on a rental run hundreds of pages and were written for underwriters, not owners. Below is what actually applies, in plain English, so you can walk into the conversation knowing what your file will look like.
What a conventional refinance on an investment property actually is
A conventional loan is written to the standards of the agencies that buy mortgages on the secondary market. When the property is a rental rather than your home, the same program applies with tighter settings. There are two versions, and the difference between them drives everything else.
Rate-and-term refinance. You replace the existing loan and take essentially no cash back. Closing costs can be rolled in. This is the version used to change the term, move off an adjustable rate, or drop a payment.
Cash-out refinance. You take a new loan larger than what you owe and receive the difference. This is how owners pull equity out of a rental, whether for repairs, the next down payment, or retiring a balance that costs more than the mortgage does.
Which label your file carries matters more than most people expect: the ceilings and the pricing are set separately for each.
The loan-to-value limits that decide the whole conversation
This is where most refinance plans on a rental either work or stop working. For conforming conventional financing on an investment property, the current ceilings are:
| Transaction | 1 unit | 2 units | 3-4 units |
|---|---|---|---|
| Rate-and-term refinance | 85% | 75% | 75% |
| Cash-out refinance | 75% | 75% | 70% |
Read that table twice. The ten-point gap between the two rows on a single-unit rental is where most plans live or die. Own a single-family rental worth $400,000 and owe $300,000, and you sit at 75%: a rate-and-term refinance is comfortably in range, while a cash-out at that same 75% ceiling leaves you nothing to take. To pull $40,000 out, you would need the appraised value closer to $455,000.
The loan amount also has to fit the conforming limit for your area. For loans originated in 2026, the baseline one-unit limit is $832,750, rising to $1,249,125 in high-cost counties, per the Federal Housing Finance Agency. Two- to four-unit limits step up from there, and Alaska and Hawaii use the higher figure as their baseline.
One practical note: the appraisal decides the value, not the listing sites. Rental appraisals sometimes land below what an owner expects, especially when the unit is occupied and the interior has not been updated. Build room into your assumptions.
Two timing rules that quietly kill files
Two waiting periods apply to conventional cash-out refinances. They are independent of each other, and both have to clear.
Twelve months on the loan you are paying off. A first mortgage paid off through the transaction must be at least twelve months old, measured note date to note date. Subordinate liens being paid off are exempt, as is a buyout of a co-owner under a legal agreement.
Six months on title. At least one borrower must have been on title for six months before the new loan disburses. Carve-outs exist: property acquired by inheritance or awarded in a divorce or dissolution has no waiting period, and if the property was held by an LLC you majority-own or control, that time counts toward the six months.
That LLC point catches investors constantly. The time in the LLC counts, but to close, title has to move out of the LLC and into your name as an individual. If your operating structure depends on the property staying in the entity, conventional may not be the right fit, and that is a conversation worth having before an application is started.
One smaller rule: if the property has been listed for sale, the listing has to come off the market by the disbursement date.
Reserves: the requirement nobody budgets for
Reserves are liquid assets left over after closing, measured in months of payments. On rentals this is often the line that surprises an otherwise strong borrower, and two separate tests can apply at once.
Reserves on the subject property. On a cash-out refinance run through automated underwriting, if your debt-to-income ratio exceeds 45%, six months of reserves is required.
Reserves on your other financed properties. This is the one that catches people. You document additional reserves calculated as a percentage of the combined unpaid balances on your other financed properties, not counting the subject property or your own home:
- 2% of the combined balance if you have one to four financed properties
- 4% if you have five or six
- 6% if you have seven to ten
An investor with $345,000 in combined balances across four other rentals plus a primary residence sits in the 4% tier: roughly $13,800 in additional documented reserves, on top of whatever the subject property requires. That has to be money in an account you can document, not equity you plan to pull at closing.
How many rentals can you finance this way
Conventional financing supports up to ten financed properties, including your primary residence. Standard eligibility applies through six. From seven to ten, a minimum representative credit score of 720 is required and the higher reserve tier kicks in.
Some holdings do not count: commercial real estate, buildings with five or more units, timeshares, vacant lots, and property titled to a corporation where you are not personally obligated. If you are near the ceiling, confirm the count carefully. It is easy to overstate.
Past ten financed properties, or if your structure requires title to stay in an entity, conventional is not the tool. A DSCR loan qualifies on the property's own rental income rather than your personal debt-to-income ratio and generally permits entity vesting. Neither option is better in the abstract. They solve different problems, and a loan officer can tell you which problem you actually have.
Rental income and how it gets counted
Underwriting does not credit you with the full rent. Documented rent is reduced by a vacancy and maintenance factor before it counts toward qualifying income, and if the property shows a loss after that adjustment, the shortfall becomes a liability against your debt-to-income ratio.
Where the income figure comes from depends on how long you have owned the property. Established rentals are documented from Schedule E on your tax returns. Recently acquired properties without a full year of history rely on an appraiser's rent schedule and your executed leases.
If your Schedule E shows large one-time repairs, say so early. Depreciation and certain non-recurring expenses can often be added back, and an underwriter who sees the explanation upfront treats the file very differently than one who finds an unexplained loss in week six.
Run the math on the full cost, not the rate
The rate is one input, and on an investment property it is rarely the input that decides whether the deal is worth doing.
Investment-property pricing carries adjustments tied to occupancy, loan-to-value, credit score, and whether cash is being taken out. Those adjustments arrive as a higher rate, as points paid at closing, or as some mix. Two offers quoting the same rate can differ by thousands in what you actually pay.
Four numbers tell you whether a refinance earns its keep:
- Total cash to close, including points and prepaid items.
- The change in monthly cash flow after the new payment lands, which is not the same as the change in rate.
- The break-even month, meaning total costs divided by monthly savings. If break-even falls past how long you plan to hold the property, the math does not work no matter how the rate looks.
- Your blended cost across everything the loan pays off. If a cash-out refinance retires a balance priced well above the mortgage, the honest comparison is the blend, not the mortgage rate by itself.
The Consumer Financial Protection Bureau publishes a clear method for this comparison. On the Loan Estimate, the fees that vary by lender sit in Section A origination charges, Section B services, and Section J lender credits. Page 3 carries an "In 5 years" line showing total dollars paid over five years, which is a better single comparison than any rate quote. CFPB guidance is to request Loan Estimates on the same loan terms and compare them side by side.
One caution worth stating plainly: a cash-out refinance converts unsecured debt into debt secured by the property. Sometimes that is the right trade, sometimes it is not. Make the call deliberately, with the numbers in front of you.
Taxes deserve a call to your CPA
Per IRS Publication 527, when you refinance a rental for more than the previous outstanding balance, interest allocable to proceeds not used for the rental generally cannot be deducted as a rental expense. What you do with the cash affects the deduction. Points work differently too: as prepaid interest, they are generally deducted over the loan term rather than in full in the year paid.
We are not tax advisors, and this article is educational rather than advice. Put the plan in front of your CPA before you commit to a cash-out structure. A short call can change how you allocate the proceeds and what it costs you at filing.
What to have ready before you apply
Investment property files are documentation-heavy. Assembling these shortens the process:
- Two years of personal tax returns with all Schedule E pages
- Current leases on every rental you own
- Mortgage statements for all financed properties, with balances and payments
- Two months of statements for the accounts holding your reserves
- Insurance declarations for the subject property, including the landlord policy
- Entity documents, if the property is currently titled to an LLC
- HOA information, where it applies
Where GoodLoan fits
We look at the full picture before quoting anything: the loan-to-value the appraisal will support, whether the seasoning rules are met, what your reserves actually document, and how the payoff structure changes your blended cost.
Sometimes the answer is no. We say no fairly often, and we would rather say it in a fifteen-minute call than after you have paid for an appraisal.
If you want to know where a rental stands, a loan officer can walk the numbers with you. No application to start, nothing to sign to have the conversation. GoodLoan is a licensed mortgage lender (NMLS #1972491) and VA-approved.
Frequently asked questions
Can I refinance a rental property that is currently occupied by a tenant?
Yes. A tenant in place is expected on an investment property. You provide the executed lease, and the appraiser needs interior access. Give notice per your lease and your state's requirements, and build a few extra days into your timeline for scheduling.
How much equity do I need for a cash-out refinance on a rental?
Enough to stay at or below the ceiling after the new loan. On a one-unit or two-unit rental that ceiling is 75% of appraised value; on a three- or four-unit it is 70%. At 75%, a property appraised at $500,000 supports a maximum new loan of $375,000. Whatever exceeds your payoff and closing costs is what you can take.
Does the six-month title requirement apply if I bought the property with cash?
A delayed financing exception lets you recover your investment sooner if the purchase was arm's length, no mortgage financing was used, the source of funds is documented, and the new loan does not exceed your initial investment plus closing costs and points. Confirm your situation qualifies before counting on it.
Can I move the property back into my LLC after closing?
Time held in an LLC you majority-own counts toward the six-month title requirement, but title has to be in your individual name to close. What happens afterward involves your due-on-sale clause and your attorney's read of it, so ask them before assuming. If entity vesting is non-negotiable for you, a DSCR loan is likely the better structure.
Will a cash-out refinance on my rental hurt my ability to buy another property?
It can go either way, depending on what the cash does. A larger balance raises the payment and can reduce the qualifying income the property contributes. The cash itself can become the next down payment and can count toward reserves once it sits in a documented account. Model it before you file.
How long does a conventional refinance on an investment property take?
Plan on longer than a refinance of your own home. The added time comes from coordinating appraisal access with your tenant, documenting rental income, and verifying reserves across multiple properties. Files with the leases and statements assembled upfront move a lot faster than files where documents trickle in.
