Three Ways Our

Investment Property Calculator

Will Make You the MacGyver of Real Estate Investing

Secret agent Angus McGyver had his trusty Swiss Army knife, but you’ll be able to solve your way out of the three most common real estate investment mistakes with our new investment property calculator.

Wondering how you can calculate the return on your investment property? Try out our calculator on HowManyDoors-dot-com - it’s just one of the many resources we offer.

Our Investment Property ROI Calculator is the first and only calculator with automated data updates, like price, rent, insurance premiums, management fee estimates, and more - and you’ll only find it here on HowManyDoors.

For as many investment property options as there are, there are likely to be as many different ways of calculating the return on your investment. But what bothered me most about investment property calculation methods is not how many there are, but that I found them to be either way too complex or too simplified.

When it comes to rental property investments, the only objective is to calculate the potential to create cash flow and to measure said investments against only that criteria. It’s critical that you understand how you can get a return on your investment, and it requires a realistic and inclusive view on income and expenses. When I was getting my start in investment property, I got so frustrated trying to pull together accurate data - double checking my calculations on various websites and calling for quotes from insurance companies, etc. - that I decided to create my own calculator so I could do it myself.

Armed with a better way to calculate the return on investment (ROI) for a property, I can “MacGyver” my way around three of the most common mistakes investors make (no dental floss required):

  1. Getting rental rates incorrect: This is a frequent mistake with turnkey rehab homes, where the first year’s rents are guaranteed, and with new builds.
  2. No consideration for the vacancy rate: At some point your property will be unoccupied, and you have to include that in your calculation.
  3. Not enough and inaccurate data: Without a tool like our investment property calculator, which has real-time feeds of industry data, it’s easy to miss things like property management fees or repair and maintenance funds. And if you skimp on your research, you might be missing the whole picture on income and expense data from the many databases you can consult.

We created an investment property calculator to address each of these mistakes.
