How to Create a Rental Property Pro Forma in Seconds (Instead of 60 Minutes)

When evaluating a rental property, everything comes down to one thing:
Do the numbers actually work?

If you don’t properly underwrite a deal, you risk buying a property that looks good on the surface—but quietly loses money over time.

That’s where a pro forma comes in.

What Is a Rental Property Pro Forma?

A pro forma is a financial projection that estimates how a property will perform as an investment.

It helps you answer:

• How much income will this property generate?
• What are the true operating costs?
• Will this deal actually cash flow?

What You Need to Analyze a Rental Property

To build a proper pro forma, you typically need to gather:

1. Market Analysis (Comps)

Understanding comparable properties is critical for:

• Property value
• Rental income potential

2. Rental Income

• Long-term rental (LTR) estimates
• Short-term rental (STR) projections

3. Operating Costs

Including:

• Property taxes
• Insurance
• Utilities
• Maintenance
• Property management

4. Cap Rate

A key metric used to evaluate deal performance:

• ~4%+ for long-term rentals can be viable (market dependent)
• ~6%+ for short-term rentals may indicate a strong opportunity

The Traditional Way (45–60 Minutes Per Property)

Most investors and agents still do this manually:

• Pull comps from the MLS
• Estimate rent using multiple platforms
• Build spreadsheets
• Manually input expenses
• Adjust assumptions line by line

This process is:

• Time-consuming
• Error-prone
• Difficult to scale
