Property Deal Analyzer

Example:

Suppose a rental property generates:

Monthly Rental Income: 50,000

Annual Operating Expenses: 100,000

Annual Mortgage Payments: 250,000

First, calculate the annual rental income: 50,000 × 12 = 600,000

Then subtract the annual operating expenses and mortgage payments: 600,000 - 100,000 - 250,000 = 250,000 Estimated Annual Cash Flow: 250,000


Property Deal Analyzer

A property can look attractive at first glance, but the purchase price is only one part of the picture.

Rental income, expenses, financing, renovation costs and the amount of cash invested can all change how the numbers look.

The Prozameen Property Deal Analyzer brings these figures together so you can review a property from several financial angles before making your own assessment.

What Does the Property Deal Analyzer Show?

Enter the available property and financing details, and the tool will calculate useful metrics such as:

  • Estimated Loan Amount
  • Total Cash Invested
  • Annual Rental Income
  • Net Operating Income
  • Estimated Annual Cash Flow
  • Rental Yield
  • Loan-to-Value Ratio
  • Cash-on-Cash Return
  • Estimated Annual ROI

Rather than looking at one number in isolation, you can see a broader financial picture of the property.


How to Use the Tool

Enter:

  • Property Purchase Price
  • Down Payment
  • Purchase Costs
  • Renovation Costs
  • Monthly Rental Income
  • Annual Operating Expenses
  • Annual Mortgage Payments

The tool will automatically calculate the property metrics and present them in a clear summary.


Understanding the Results

Estimated Loan Amount

This is the portion of the property price remaining after the down payment.

Loan Amount = Property Price - Down Payment


Total Cash Invested

This shows the estimated amount of your own money committed upfront.

Total Cash Invested = Down Payment + Purchase Costs + Renovation Costs


Annual Rental Income

Monthly rent is converted into estimated annual rental income.

Annual Rental Income = Monthly Rent × 12


Net Operating Income

Net Operating Income, or NOI, represents rental income remaining after operating expenses.

NOI = Annual Rental Income - Annual Operating Expenses

Mortgage payments are not included in NOI.


Estimated Annual Cash Flow

Annual cash flow shows what may remain after operating expenses and annual mortgage payments.

Annual Cash Flow = Annual Rental Income - Annual Operating Expenses - Annual Mortgage Payments

A negative result means the entered expenses and debt payments are higher than the entered rental income.


Estimated Rental Yield

Rental yield compares net annual rental income with the property purchase price.

Rental Yield = NOI ÷ Property Price × 100


Loan-to-Value Ratio

Loan-to-Value, or LTV, compares the estimated loan amount with the property's purchase price.

LTV = Loan Amount ÷ Property Price × 100


Cash-on-Cash Return

Cash-on-cash return compares annual cash flow with the amount of cash invested.

Cash-on-Cash Return = Annual Cash Flow ÷ Total Cash Invested × 100


Estimated Annual ROI

The tool can also estimate annual operating return relative to the total property acquisition cost.

ROI = NOI ÷ Total Investment Cost × 100

Where:

Total Investment Cost = Property Price + Purchase Costs + Renovation Costs


Why Use a Property Deal Analyzer?

Real estate decisions often involve several moving parts.

A property may have strong rental income but high expenses. Another property may require a larger upfront investment but have lower financing costs.

Looking at several metrics together can make it easier to understand how the numbers relate to one another.

The tool is designed to support your research—not make the decision for you.


Important Information

The Property Deal Analyzer provides estimates based entirely on the information entered.

Actual property performance may be affected by vacancy, unexpected repairs, taxes, insurance, financing changes, interest rates, rental-market conditions, property appreciation and other factors.

The tool does not label a property as a good deal or bad deal and does not recommend whether you should buy, sell or invest.

 

Frequently Asked Questions

What is the Property Deal Analyzer?

The Property Deal Analyzer helps estimate a property's annual cash flow using rental income, operating expenses and mortgage payments.

How is estimated annual cash flow calculated?

The tool uses this formula: Estimated Annual Cash Flow = (Monthly Rental Income × 12) - Annual Operating Expenses - Annual Mortgage Payments

What does a positive annual cash flow mean?

A positive result means the rental income entered is higher than the operating expenses and mortgage payments entered.

What does a negative annual cash flow mean?

A negative result means the operating expenses and mortgage payments entered are higher than the rental income entered.

What should I include as annual operating expenses?

You may include recurring costs such as maintenance, insurance, management fees, service charges, property taxes and other property-related operating expenses.

Does the Property Deal Analyzer tell me whether I should buy a property?

No. The tool only provides an estimated cash-flow calculation based on the information entered. It does not recommend whether to buy, sell or invest in a property.
