Hello BP forum,  I am interested in investing in the US generally and would like to build a medium to large rental portfolio,  are there any key areas I should be looking at or should stay away from? 

You have to account for that.4) This is all about the rental numbers, and if this is subject to rent control, right now the max you can raise rent is 4%.

https://www.fincen.gov/resources/filing-informationI went onto the Fincen website and there are a bunch of forms...So I cant figure out which form to fill outWe have a few LLCs that hold rentals...

You qualify as REPS already, so any rental investment can wipe out your taxes.

We've come to realize that the Boston market is too tough and the numbers don't make sense (to even house hack), so just recently, we decided to hone in on Plymouth, MA... with the idea that it could be a good tertiary market to do furnished rentals (thinking short-term/AirBnB in the summer, and mid-term in the offseasons).

I apologize if I wasn't clear on my question, I didn't really go into my plans for how I would invest as I didn't think it really pertained to my question, yes I know I should not purchase a rental using a HELOC and certainly that wasn't the plan.Whether it be a flip or brrrr, I would use some investment vehicle that would allow me to pay back the money.Roll into as when I purchase my next primary home, use the equity towards the house.The premise of my question was just is owning a home expensive enough now to where it'd be worth putting more money towards it when purchasing to lower payment/pay off quicker, or would it still be worth it to use all of that money towards other real estate. 

Anyone here doing Mid term Rentals in Las Vegas ? 

Some have juiced that up too with all kind of party rental items. 

A key improvement was removing a wall to create a larger, open space, significantly boosting its rental potential.
