I have heard on the Bigger Pockets podcast multiple individuals with more than 10 properties. 

Hello bigger pockets, I have come across a multi-family unit 6-plex.

@Frankee MurphyWelcome to Bigger Pockets.

I’ve found a few good articles on Bigger Pockets – but honestly it seems like there is way too much information on this site to shift through6.

Bigger pockets is a great way to brain storm our way through different situations with great minds. 

Keep in mind that you cannot keep doing that method, you'd have to change location (couple miles away or closer to work), or if you stay in the same location you have to buy a bigger property.

Because of my location, I have a variety of options, from smaller multifamily places in a city with low crime, larger 6-10 unit low rises in higher crime areas, or bigger 10-20 unit low rises in small towns.

Hi Bigger Pockets Crew!

So, it will give you bigger deduction, and because of that, potential bigger "tax saving" in the first years, but you'll get less later too.
