Which equity access method actually fits the BRRRR timeline, HELOC or cash-out refi on the donor property?

Question

The tension I keep coming back to is that a HELOC on an existing property gives you a draw you can time to the rehab spend, so you are only carrying interest on what you have actually pulled, while a cash-out refi hands you a lump sum the day you close and starts the full interest clock whether the contractor shows up that week or three weeks later. On a six-month rehab that matters. Take a property with 180k in equity and a HELOC at prime plus one versus a cash-out refi that adds 150k to a 30-year note: the cash-out refi is cheaper per dollar if rates cooperate and you deploy fast, but the HELOC wins if the rehab drags and you are sitting on undeployed capital. The BRRRR timeline is the variable that breaks the math one way or the other. The other piece most people skip is what happens to the donor property's DSCR when you strip equity out of it through a cash-out refi. If that property is also financed, the new payment may push it below the coverage ratio a future lender wants to see, which matters if you are stacking deals. A HELOC stays off the amortizing debt column in some lender calculations, though confirm that with your specific lender in writing because it depends on the product and the institution. How long is your rehab window realistically running, and is the property you are borrowing against already carrying a mortgage?

The core of what you laid out is right. The draw-as-you-go nature of a HELOC genuinely does reduce carrying cost during a slow or staggered rehab, and the DSCR point on the donor property is one that a lot of people miss until a lender flags it mid-application.

A couple of things worth confirming before you run the comparison to a final number.

First, HELOCs on investment properties, meaning properties you do not live in, carry meaningfully higher rates than HELOCs on a primary residence. That narrows the advantage over a cash-out refi, sometimes enough to flip the math even on a dragging six-month rehab. Ask each lender what the spread is on an investment-property HELOC versus a primary, and price both scenarios with the real rate.

Second, the DSCR observation you made cuts in both directions. A cash-out refi raises the donor property's monthly payment and can drop its debt service coverage ratio below what a lender wants to see. DSCR, which is just net rental income divided by the mortgage payment, often needs to sit at 1.25 or higher for a lender to count the property as healthy. But some lenders count an open HELOC line as a liability even before you draw on it, because the full line shows as available debt. I'd ask each lender specifically how they treat an open HELOC on a qualifying analysis for the next loan, and get the answer in writing as you noted.

I'm not able to tell you which one wins for your situation without knowing the rate you'd actually get on each product, and whether the donor property carries an existing mortgage.

What does your realistic rehab window look like, and is the property you're borrowing against a primary residence or an investment property?

The DSCR point is the one I want to push on because the post frames it like a future problem but on my end it showed up immediately. I was trying to pull equity out of a paid-off duplex in late 2023 to fund a rehab two counties over and the lender on the acquisition side wanted to see the donor property's debt service as part of my overall picture before they would even talk about the refi on the new one. So stripping 150k out via cash-out on the donor did not just affect future deals, it affected the deal I was actively trying to close at the same time. The two transactions were talking to each other in ways I did not anticipate until I was already mid-process.

On the HELOC rate framing, prime plus one sounds manageable until you run it out. Prime right now is sitting at 8.5 so you are at 9.5 variable, and on a six-month draw of say 90k average balance that is not nothing. The post says the cash-out refi is cheaper per dollar if you deploy fast and I would push back on that depending on what your 30-year rate looks like today. I am running numbers on the 47 acres situation right now and the spread between a fixed cash-out product and a HELOC draw is not as clean as the videos make it seem once you factor in the origination costs on the cash-out. What does your all-in closing cost look like on the cash-out refi you are modeling, because that number is doing a lot of work in the comparison and I never see people post it?

The HELOC also gives you a kill switch: close the line without drawing, and the donor property's debt service does not move at all.

The number I want is the draw schedule your contractor will actually sign: specifically, what percentage of the 150k you will pull in month one versus what sits idle through month four. That single figure is what decides whether the HELOC's variable carry cost beats the refi's fixed rate spread, because the math flips around the 60-to-65 percent deployed threshold on most prime-plus-one structures relative to a 30-year fixed at current spreads.

What portion of your rehab spend is materials and permits upfront versus labor staged across draws?

The HELOC also stays revolving, so after the refi on the BRRRR property you can pay it down and pull again on the next deal without a new origination.
