5 out of 5 starsI'd been looking at my first rental property for weeks and couldn't tell if it was actually a good deal or if I was just rationalizing it. Plugged in the real numbers (not the seller's pro forma), and in about 10 minutes I had cash flow, cash-on-cash return, and cap rate laid out clearly. The property didn't pencil. I passed. Found one a month later that did, and already knew exactly how to evaluate it. The cost of the calculator is a rounding error compared to what I avoided. Easily the highest-ROI purchase I've made this year.

Thank you! I'm glad to hear that it helped you quickly assess a property and decide to pass on what could have been a costly mistake. Good luck with the new property!

5 out of 5 starsThis is very useful! Saves time and is really convenient for potential investments, better than others I've used before. User-friendly!

Thank you! Time savings is exactly what I was building toward. A lot of BRRRR calculators either oversimplify or bury you in inputs you have to figure out yourself. The goal was a clean middle: enough detail to actually trust the output, fast enough to run through multiple deals in a single screening session. Really glad it's hitting that mark. Good luck with the deals!

5 out of 5 starsI used this to analyze a BRRRR deal I’m considering, and it made everything super clear, especially how much cash I’d have left after refinance. The dashboard is easy to read, and I was able to evaluate the deal in under 10 minutes. Really useful!

This is exactly the kind of feedback that means the most, knowing the money-left-in-deal calculation actually helped you evaluate a real BRRRR you're considering. That's the number most tools get wrong, so I put a lot of work into making sure it was modeled correctly. Hope the deal pencils out, and feel free to reach out if you have any questions as you run more scenarios. Good luck!

5 out of 5 starsGreat tool! With only a few quick inputs it was easy to see what my cash flow and break even rental price would be. Finally something that provides the numbers I actually care about. So happy I found this!

Thank you so much, this made my day! That's exactly what I set out to build: something that cuts straight to the numbers that actually matter for making a confident buy or pass decision. Really glad it's working well for you, and I hope it helps you find a great deal. Happy investing!

5 out of 5 starsIt has always been challenging for me to analyze the financial viability of a "fixer-upper" deal. Does that initial purchase price make sense? How about the fixing/remodeling costs? Will I have a sufficient profit from this deal? Especially compared to other investment opportunities? In the past, I relied on very rudimentary calculation: 1) How much I paid for the property? 2) How much I invested in fixing/upgrading it? 3) Was the (estimated) post-repair value greater than 1+2? I knew this was an insufficient investment analysis. But that's all I had. With this BRRRR calculator I can finally do a pro-level analysis of a real estate investment opportunity. It greatly increases my confidence in my decision making process!!

Thank you! This is exactly why I built it, that purchase + rehab vs. ARV math always felt incomplete to me too. So glad it’s helping you analyze deals with more confidence. Happy investing!

5 out of 5 starsI used the rental property calculator to analyze a potential purchase of a rental property. In the past, I tried doing the analysis by creating an Excel spreadsheet myself. However, the process was cumbersome and there were quite a few factors I failed to consider. This rental property calculator made the investment analysis significantly easier and far more thorough. It provides tremendous value to real estate investors. Given the high costs involved (i.e. hundreds of thousands of dollars) using this calculator is definitely the smart thing to do.

Really appreciate this! Building your own spreadsheet from scratch is such a pain, and it's so easy to miss things like vacancy, maintenance reserves, or break-even rent. Glad this saved you the headache and gave you a more complete picture. Good luck with the property!

5 out of 5 starsVery useful investment calculator! We were deciding whether to buy a condo and didn't trust the answers we were getting from ChatGPT and free online calculators. This investment calculator made me feel like I got a business degree; I learned a lot about what to consider when deciding whether or not to invest in a property, and it ultimately helped us make a decision. Thank you so much!
Idan responded on Apr 10, 2026
I love this! ChatGPT giving you real estate investment advice is a little scary. Really glad you found this more trustworthy and that it helped you actually make a decision. That's exactly what it's designed for. Hope the condo works out!

1 out of 5 starsMy biggest complaints with this seller are not only the product, but his lack of care in making it right with his customer. I contacted him and explained in detail why his spreadsheet did not work, which he admitted. Then I advised the seller that this is NOT a very user friendly product and I wanted a refund. His short response was basically - no refunds allowed. Customer service is everything, and this is a seller you should be weary about.

Hi John – you were right. The Financing section had a bug, and I appreciate you working through it with me across several messages to help me trace exactly what was wrong. I've since fixed it in the master template and updated the How to Use guide with the missing hard-money walkthrough. Every buyer, not just this order, now has the corrected version. I'd also asked for your deal numbers so I could check your specific setup directly. I didn't hear back on that, but the offer still stands. Like most digital templates, this listing is final sale once downloaded, but making sure it actually works for you is what matters most to me.
