Bulk Analyze "For Sale" Listings in Seconds

Instantly see which properties are worth buying as rentals — RentOptix calculates your returns directly from your Bright MLS export or any property CSV file.

Looking to expand your rental portfolio but unsure which “For Sale” properties will meet your profit goals? RentOptix bulk analyzes property lists to instantly determine whether the sales price will yield a profitable rental. We calculate the potential rent, factor in the purchase price and costs, and show the expected rental profit. If a property isn’t profitable at its listed price, we’ll tell you the price you need to pay to make it a smart investment.

Getting started is simple: Register your email for free, upload your property list, set your ROI or Cap Rate goals, and instantly see which homes meet your targets. Save hours of manual calculations — our tool automates the math for you. Upload a spreadsheet of properties you’re evaluating and see immediately what purchase price achieves your target ROI (cash-on-cash return) or Cap Rate.

NOTE: Our calculations use 1 month's rent for leasing costs, 6% of the gross monthly rent for maintenance reserve, and 6% of the gross monthly rent for estimated insurance costs.
