@Alejandro Saenz First off, there is a tradeoff in BRRR and BRRR calculators to consider. They higher the ARV, the higher the potential loan amount at Refi. At some point, the Refi loan my kill the cash flow. Dont let this kill your interest in the deal, you can take a lower loan amount to make the property cash flow, and tap the equity in other ways. Or you could sell the property as a flip.
What you are touching on is the key issue for almost all real estate investors - finding good deals. Keep in mind, many books were written and many "experts" were made after 2009 - in a market where deals fell out of the sky. That market doesnt exist anymore, but you can find deals. However, the competition is stronger than in the last decade by far. If its an easy deal to find, someone else has already found it. In fact, if you find a deal, go ahead and ask why someone else hasnt bought it. I have found deals in this market, and several of them on the MLS. However, they were major rehab projects which I wasnt afraid to tackle.
Once your research and learning gives you the basics, focus on a niche that set you apart. for me its old houses, and houses in really bad shape. The other option is start your own direct marketing, but this is competitive as well, and involves learning a whole new business. The secret on real estate is out, and nearly every market is saturated with buyers. The good thing is, unlike the stock market real estate is local, and there is no national exchange. Look for properties in less crowded areas. I have been finding properties in small towns where i grew up, where i intimately know the area.
Finally, remember a deal doesnt have to be a perfect BRRR to be a good BRRR. The goal is to limit you capital investment, to maximize your return on capital. That doesnt mean eliminate your investment. In the standard way of buying rental properties, you have to put 25% cash down. So any deal you do that allows you to put less than 25% is better than the norm. If you leave $10,000 in a deal that cash flows $150 per month, thats still an 18% cash on cash return. Try getting that in the stock market.
