Custom-Built vs All-in-One CRMs: What Real Estate Investors Should Know

If you’re scaling your real estate business, you’ll face this choice:

• Custom-built CRM (like Left Main on Salesforce)
  
• All-in-one CRM (like REsimpli)
  

With the various CRM options available on the market, the question often comes up: Left Main CRM or REsimpli? 

Both claim to help you close more deals. But the paths to get there are drastically different.

Let’s break down the pros, cons, and hidden costs of each so you can make the right call for your investing business.

What You Get With a Custom CRM Like Left Main

• Flexible structure
• Advanced reporting (if configured)
• Salesforce marketplace apps

But also:

• Requires onboarding specialists
• Needs constant admin/developer time
• High learning curve for new team members
• Not mobile-optimized for fieldwork
• You’re paying for features you’ll never use

Left Main is essentially a template on top of Salesforce. If you’re not familiar with Salesforce or don’t have a dedicated admin, it can feel like trying to turn a space shuttle just to send a postcard.

What You Get With an All-in-One CRM Like REsimpli

• Purpose-built for real estate investors
• Built-in lead management, dialer, marketing, AI, and accounting
• No integrations or third-party subscriptions required
• Clean UI, easy to learn
• Automate call answering, lead scoring, appointment summaries, and follow-up triggers through advanced AI agents.
• Mobile app with Driving for Dollars

But:

Less “custom” flexibility than a raw Salesforce setup (but 90% of investors don’t need that level of complexity anyway)

Real Costs to Consider (Not Just the Subscription)

Who Should Use Each?

Wrap-Up: All-in-One Wins for Investors

Unless you’ve got a dev team and a budget to match, the all-in-one route will help you scale faster and with fewer headaches.

If you’re spending more time inside your CRM than out finding deals, it’s time to switch to REsimpli and streamline your business to close more deals and increase your ROI.
