How much can you budget for furnishings and all kitchen items and creature comforts for the ones you want to MTR.If you have a vacant 6-unit, you have great possibilities to try all strategies.

I would advise picking one of those strategies and rolling with it.

It doesn't make sense to you because you still don't understand the strategy.

I agree with @Nicholas L. regarding the house hack strategy. 

Great tools that get updated regularly.I am on the lending side of things and would be happy to hop on a call with you anytime to discuss financial strategies and help answer any questions you may have about nearly any loan product available to help you on your journey, even if they are not products my capital partners offer.We are all here to help you learn and grow.

I'm indifferent towards the strategy but would be open if approached. 

Move on if that is your strategy. 

Would recommend you read a couple books about BRRRR, that will give you the basics and then feel free to reach out.It remains a great strategy, but you have to manage your expectaions.

Work on your credit, and look for a deal that works on any exit strategy.

Have you thought of which states  you will invest in and also the strategy like BRRRR or fix and flip or STR?
