Use Your HELOC for Investment Property
8 min read · March 2026
You need 20-25% down to buy a rental property. On a $440,000 home in Colorado Springs, that's $88,000-$110,000. Most people don't have that sitting in a savings account. But if you own a home in Colorado, you might be sitting on it without realizing it.
A HELOC on your primary residence gives you the down payment for an investment property without selling anything, touching your 401(k), or refinancing your low-rate mortgage. You pull equity from the home you own and use it to buy a home that pays you rent.
The Strategy: Primary Home Equity → Rental Property
Here's how it works:
Your primary home has equity. You open a HELOC at up to 85% CLTV on a primary residence (640 minimum credit score). You draw the amount you need for the down payment on the rental.
The rental property gets a conventional investment property mortgage — typically 20-25% down, separate loan, separate terms. Your HELOC funds the down payment. The rental income covers both the investment property mortgage and your HELOC payment.
Your existing mortgage on your primary home stays untouched. Same rate. Same payment. The HELOC is a second lien — completely separate.
I run this play with Colorado investors all the time. The math works when the rental income exceeds your combined monthly costs. Let me show you what that looks like.

Tom and Rachel in Castle Rock had a $625,000 primary home with $220,000 left on the mortgage at 3.25%. They'd been watching the Colorado Springs rental market for months and found a 3-bedroom single-family home listed at $440,000.
They needed 25% down — $110,000 — plus closing costs. Total: about $120,000.
We opened a HELOC on their Castle Rock home at 85% CLTV. Accessible equity: $311,250. They drew $120,000 for the down payment and closing costs.
The investment property mortgage (conventional, 30-year) gave them a payment of approximately $2,050/month including taxes and insurance. Their HELOC payment on the $120,000 draw: about $900/month on a 20-year term.
The rental? $2,400/month on a 12-month lease. Signed before they closed.
Monthly income: $2,400. Monthly costs: $2,950 (mortgage + HELOC). That's a -$550/month gap before tax benefits. But here's where it gets interesting — the mortgage interest, property taxes, depreciation, and HELOC interest (used to acquire the property) are all deductible against rental income. After tax benefits, they're cash-flow positive.
And every month, the tenant pays down both the investment mortgage and the HELOC. Tom and Rachel are building equity in two properties simultaneously — with one application.

Investment Property HELOCs: What You Need to Know
There are two paths here, and they're different:
Path 1: HELOC on Your Primary Home (For the Down Payment)
This is the most common strategy. You tap equity from the home you live in to fund the purchase of the rental. Requirements:
640 minimum credit score. Up to 85% CLTV. $25,000 to $750,000 loan amount. Funded in as few as 5 days. This is a standard primary residence HELOC — the fact that you're using the funds for an investment doesn't change the terms.
Path 2: HELOC on the Investment Property Itself
Once you own a rental with equity, you can open a HELOC directly on that property. Requirements are tighter:
680 minimum credit score. CLTV limits are lower than primary residence. You need a clean payment history on the investment property. But it works — and it lets you tap equity from the rental to buy your next rental. That's how portfolios scale.
Where the Rental Math Works in Colorado Right Now
Not every Colorado market pencils out for rental investment. Here's where I'm seeing the numbers work:
| Market | Median Price | 25% Down | Typical Rent (3BR) | Rent-to-Price Ratio |
|---|---|---|---|---|
| Colorado Springs | $482,000 | $120,500 | $2,200-$2,600 | 0.49% |
| Aurora | $485,000 | $121,250 | $2,100-$2,500 | 0.47% |
| Pueblo | $280,000 | $70,000 | $1,400-$1,700 | 0.55% |
| Fort Collins | $610,000 | $152,500 | $2,400-$2,800 | 0.43% |
| Greeley | $420,000 | $105,000 | $1,900-$2,200 | 0.49% |
Pueblo has the best rent-to-price ratio on the Front Range. Colorado Springs gives you strong rents with better appreciation potential. Fort Collins is pricier but benefits from Colorado State University's rental demand.
Honestly, I wouldn't buy a rental property anywhere in Colorado without running the full cash flow analysis first — HELOC payment, investment mortgage, taxes, insurance, maintenance, vacancy. If the numbers don't work, I'll tell you. That's part of the job.
The Timing Advantage
Look. Good rental properties don't sit on the market for 45 days while your bank processes a cash-out refi. They're gone in a week.
A HELOC funded in 5 days means you can make an offer with proof of funds before the next investor even gets their bank on the phone. In competitive markets like Colorado Springs and Aurora, speed is a real edge.
And because the HELOC gives you a draw period (3-5 years depending on your term), you can draw for the first property, pay it down with rental income, and draw again for the next one. It's a revolving line, not a one-time lump sum.
INVESTOR TIP
Set up autopay on your HELOC for a 0.25% rate discount. On a $120,000 draw, that saves you $300/year. And every time the Fed cuts rates, your HELOC payment drops automatically — improving your cash flow on the rental without any action on your part.

Get Your Equity BlueprintDon't Overpay for Homeowners Insurance
Rental properties need landlord insurance — not a standard homeowners policy. Landlord policies cover the structure, liability, and lost rental income if the property becomes uninhabitable. Our insurance team compares 30+ carriers for both your primary home and your rental. Getting both policies through one team often means better rates and no coverage gaps.
