I am in no rush and want to take this slow and methodically.

All I'm saying is you don't know what you haven't done, so you really can't say you've done it all.The most important things you learn by just doing is what not to do since that method will generate more mistakes than not. 

What’s decreasing basis in the BRRR method and any examples would be a good help as well.

Look to talk to someone with insight on the matter.Recently watched the video of Rafael talking about making around $40k/month doing the arbitrage method.

I then follow up all three ways until I figure out the listing agent's preferred method of communication to make sure that an offer is seen and presented.

However, I'd like to vocalize my opinion on here and it can just be taken with a grain of salt:My intention here is not to guide you to any decision but to suggest considering if you can achieve your goals via other methods and consider the opportunity cost of both doing and not doing something.

I just started reading the multi family millionaire and learned about the stack method etc.

And part of me wonders am I trading a 10yr loan for 30 yr loan at the same price, although I'd be adding $100k in assets ($180 cash out minus $80k loan payoff = $100k to buy 2 properties).

By the time everyone else had received their insurance payouts, there were no contractors available but my friend's house was nearly rebuilt.Also, it's always good to have some cash on hand because you never know when a killer deal is going to pop up that you can jump on while everyone else is trying to figure out where to get the money.So, my opinion, and the opinion of just about everyone here on BP doing BRRRR method, is to refinance all the time even if rates are higher in the future.
