Purchased mortgage leads typically cost $15-$45 each but are often resold to three to five other loan officers at once, which drags close rates down to roughly 1-3%. A self-built funnel — Google Ads, Meta, a dedicated landing page, and a follow-up sequence — usually runs $50-$150 per lead, but those leads are exclusive to you, arrive warmer, and close at 5-12% depending on how fast you follow up. Run the math to a funded loan instead of a raw lead, and the two options land much closer together than the sticker price suggests — and the funnel gets cheaper every month while purchased leads never do.
What does a purchased mortgage lead actually cost?
Lead aggregators and lead-marketplace platforms sell mortgage leads that a homeowner submitted once — usually a rate-shopping form — to whoever bought them in that ZIP code and price tier. Shared leads (sold to multiple LOs simultaneously) run cheaper, typically $15-$30. Exclusive leads from the same aggregators run $40-$90 because you're the only one calling. The catch with shared leads isn't the price — it's that the borrower has already heard from two or three other loan officers before you dial, so contact rates and trust both drop. Aggregator leads also come with zero brand equity: the borrower doesn't know you, has no reason to pick you over a competitor calling five minutes later, and often submitted the form to multiple sites at once without realizing it.
What does it cost to build your own funnel?
A self-built funnel has three cost layers, and none of them are optional if you want it to actually produce loans:
- Ad spend — Google Search and Meta lead-gen campaigns for mortgage professionals need a minimum of roughly $2,500/month to generate enough volume to optimize against; below that, the algorithms don't have enough data to find your best-performing audiences.
- Landing page and lead form — a page built specifically for pre-approval or purchase-ready leads, with your NMLS ID displayed and TCPA-compliant consent language on the form, not a generic contact page.
- Follow-up infrastructure — a CRM with automated call/text/email sequences, because a self-generated lead that isn't contacted within 5 minutes converts at a fraction of the rate of one contacted immediately.
Blended CPL for a well-run funnel across Google and Meta typically lands between $50 and $150 for mortgage-specific campaigns, higher than raw aggregator leads but with none of the shared-lead problem — the borrower found you, not a marketplace, and nobody else is calling them about the same inquiry.
How do the real costs compare per funded loan?
The number that matters isn't cost-per-lead, it's cost-per-funded-loan. Here's how the two models typically compare once close rates are factored in:
| Metric | Purchased (shared) leads | Self-built funnel |
|---|---|---|
| Cost per lead | $15-$45 | $50-$150 |
| Exclusivity | Shared with 2-5 other LOs | Exclusive to you |
| Typical contact rate | 20-40% | 50-70% |
| Typical close rate (lead to funded) | 1-3% | 5-12% |
| Rough leads needed per funded loan | 35-100 | 8-20 |
| Approx. cost per funded loan | $525-$4,500 | $400-$3,000 |
| Value over time | Flat — every lead costs the same | Compounds as retargeting, SEO, and referrals reduce blended CPL |
These are industry-typical ranges, not a promise for any individual campaign — market, loan type, and how fast you actually call back a lead all move these numbers significantly. But the pattern holds across most LOs we've seen discuss it: the cost-per-lead gap is real, but the cost-per-funded-loan gap is much smaller, and it often favors the funnel once a campaign has been running for a few months.
What compliance constraints affect this decision?
Both models carry compliance obligations, but a self-built funnel puts more of the burden on you to design around from the start. Meta's special ad category for credit-related ads restricts the demographic and geographic targeting you can use for mortgage campaigns — you lose some of the fine-tuned audience controls other industries get. Any lead form you build needs TCPA-compliant consent language before you can call or text a borrower, and your NMLS ID needs to be visible on the landing page and in ad creative per your state's requirements. Purchased leads shift the form-consent question to the aggregator, but you still need to confirm their consent language covers your outreach — don't assume it does. None of this is legal advice; loop in your compliance counsel or your broker's compliance team before launching either model.
When does buying leads make sense vs. building a funnel?
Buying leads makes sense when you need volume immediately and don't yet have the infrastructure — CRM, landing pages, a fast follow-up process — to run your own campaigns well. It's a reasonable bridge while you build that infrastructure, not a permanent strategy, because the cost per funded loan on shared leads doesn't improve with time the way a funnel does.
Building your own funnel makes sense once you can commit to the $2,500/month minimum ad spend, have (or are willing to build) a 5-minute-or-faster follow-up process, and want a channel that gets more efficient the longer it runs — retargeting audiences grow, local SEO compounds, and referral flywheels from past clients start layering on top of paid leads instead of starting from zero every month. Nova Marketing has no published mortgage case study to point to yet — it's the newest vertical we work in — so we won't claim proof either model outperforms in every market. The comparison above reflects typical ranges loan officers report, not a guarantee for any individual campaign.
Frequently asked questions
Is it ever worth running both models at once?
Yes — many loan officers use purchased leads to keep volume steady while a self-built funnel ramps up over its first 60-90 days. Once the funnel's cost-per-funded-loan drops below the purchased-lead rate, most LOs shift budget away from aggregator leads and reinvest it in the funnel.
How fast does a self-built funnel typically pay off compared to buying leads?
Most funnels need 60-90 days of consistent ad spend to generate enough data for Google and Meta to optimize targeting, which is longer than the instant volume purchased leads provide. After that ramp period, cost-per-funded-loan on a well-run funnel typically starts closing the gap with — or beating — purchased-lead costs, since exclusivity and faster follow-up both lift close rates.
Do TCPA rules apply differently to purchased leads vs. self-generated leads?
Consent requirements apply either way, but the paper trail differs — with self-generated leads, you control the consent language on your own form; with purchased leads, you're relying on the aggregator's consent language to cover your outreach. Confirm with your compliance counsel that any purchased-lead source's consent language actually permits your specific follow-up methods before you start calling or texting.
What's the minimum monthly investment to test a self-built funnel?
Nova Marketing recommends a minimum of $2,500/month in ad spend to generate enough data for Google and Meta campaigns to optimize, with management fees separate and scaling alongside total spend. Agreements are month-to-month, so a loan officer can test the funnel model without a long-term commitment while comparing results against purchased-lead costs.
