How to purchase 4th property

[Aaron Coughlin]

Hello BPers!

I currently have 2 long term rentals and 1 short term rental that are all doing great and I’m trying to figure out how to acquire my fourth property. 

Two long term rentals bring in $800 profit a month each. 
The short term brings in $4000 profit a month on average. However it is currently my primary residence and I need to keep it as such to run it.  

I would like to purchase a true commercially zoned property here in Nashville is the to run as a short term rental ideally. However I don’t have the 15-20% down payment yet. Any advice on how to acquire the best loan to use for this hypothetical purchase? I am also very close to obtaining my real estate license so that I can get back 2-3% on this hypothetical purchase. 
Any advice would be greatly appreciated. Thanks!
