Yes it is definitely possible to achieve higher cashflow by doing the rent out the room approach.

What are you hoping to achieve and why?

My "go-to" would definitely be attempting to step up to the next level and achieve commercial financing.

I also like to keep about 3-6 months of liquidity to support all the properties expenses in the event of a major crisis.Personally I sleep better with having some diversification and a piece of my networth in stocks as well so I don't feel completely reliant on real estate being the only thing that can help me achieve financial freedom.

This experience led me to passing the real estate exam and I am now looking to become an active realtor so I utilize my vast network and resources to bring other buyers, sellers, investors, and renters together to achieve their housing dreams.

For instance, if you run the numbers and see you can BRRRR and achieve a 10 percent ROI, but you know you are averaging a 30 percent ROI on most other deals, you may want to sell that property and recover your money to put somewhere else that will give you a better return.This becomes especially important when you are likely to add more equity to the property than you originally anticipated.

As a new investor, I have decided to pursue an investment strategy based on the stack technique, whereby the number of units added to my portfolio essentially doubles every year. (1) What will be the biggest obstacle to achieving this strategy, and (2) what is the best way to prepare or overcome this obstacle. 

Can I really achieve rents between $2,000 and $2,800?

Outside of purchasing a property which is not achievable for me at this time?

Why do you want to achieve FI.
