Using a 1031 exchange to capitalize on better opportunities is a great strategy.Your point about avoiding over-leverage is particularly eye-opening—it's a reminder of how critical it is to balance leverage carefully.

It doesn't quite remind me of 2004-2008 since the borrowers need to have a history of paying their bills on time and provide evidence of the capacity to repay the debt, for investment properties lenders are requiring anywhere rom 10-25% down depending on the loan amount and documentation. 

I was not informed of any such deal when I purchased the property.I was taken aback by the aggressive reply I got from the tenant after reminding him of his lease agreement even after I agreed to have my yard guy stop by next time to clean his yard.

Reminder too that once you get more properties under your belt and begin having a bigger real estate investor portfolio your file begins to get more complicated and even a simply loan like DSCR sometimes may ask to prove other items.

I tell them that in my area an eviction will make is difficult to rent a decent unit and remind them that my tenant criteria includes having no evictions. 

Do either of these platforms offer anything unique as opposed to the standard "lease renewal reminders"? 

“Winning is more fun than fun is fun”This is also a reminder to myself.

I’m just reminding you that you are probably taking a 10-20% haircut selling them in bulk and occupied.

I would certainly remind the tenant the agreed upon terms of our agreement. 

And as far as people telling you about "appreciation", remind them you are in MI, by the way.
