@Misael Carlos Vera, there are advantages of owning properties under an LLC such as as asset protection and being able to expand your portfolio of financed properties above the max personal limit of 10. However, it is much harder to refinance when the property is not in your name. I'd say if you own less than 10 properties, keep them in your own name and just be sure to have adequate umbrella protection.
Here's a tip though, do open an LLC to act as the property management company for all of your properties. It's a great way to stay organized and to keep things clean. Collect all of your rents and manage all of your property expenses through this company. Start building company credit! This is how I built up my portfolio and have been able to pick up quite a few BRRRRs leveraging business credit instead of my own. If I find a good deal, I can borrow from my company to secure it, rehab it, and then refinance it out to payback my LLC. I have done this dozens of times and the strategy works great.
