I have been planning on using the B.R.R.R.R method but was wondering if maybe I should leave that alone and find a different way to get my next property. 

depending on the size of your complex and location you will have to get a permit from you state Department of Natural resources. 

So, its only natural that the finer technical aspects of the law may be incorrect.

While this method is thorough, I've found it to be quite time-consuming.Has anyone found a quicker, more efficient way to get this information?

Naturally if you have more mortgages in your name that will affect your DTI (debt to income ratio) and ability to obtain more loans/mortgages in the future.

Tools like BatchLeads and PropStream are great for direct-to-seller strategies, but keep in mind that they come with marketing costs depending on the method you choose, such as direct mail, cold calling, or texting and have to have good nurture campaigns. 

We all have to start somewhere and I'm looking to become a expert in Section 8 rentals, the BRRR method, and AirBnb's at this time.

I always felt the method of the lottery was unfair.  

I also use the cost per mile method for mileage expense. 

Using the BRRRR method and 1031 tax deferment strategies are a great way to build your portfolio.
