@Ximei Yue welcome to the forums! BRRR'ing is a great strategy to build equity but it's a riskier play and time intensive if you're trying to do it out of state. If you have the time and effort to build out a team of a investor friendly agent, contractors and a property manager then it's a very viable option but in todays time there will be very little to no cash flow. But again it's a great way to build equity and recycle that money.
There are some turnkey providers that are vertically integrated that might be of interest to you if you want to invest passively. Companies that purchase the home with their own money, renovate them, sell to their investors and manage for them on the back end. This is also a great way to build long term wealth especially if you're investing in higher appreciating markets like Texas. Let time do it's thing over 5-10 years, you can take advantage of the tax benefits in the meantime then 1031 exchange into lower cost, higher yielding markets to achieve those goals.
Great thing abotu real estate is if you have the capital you have options and options are always good. Everyone's goals are going to be different it all comes down to what it is you want to do and how much time and effort you want to spend. Best of luck on the journey!
