They mostly will get rejected but your offers should be higher than a non-owner occupant.

Brainlsit a long list of non-discrimnatory quesitons and see where the conversation goes.

I'm curious to know if they've built in any clauses to mitigate a non-owner occupied investment.

I'm new but being mentored by a broker who did hundreds if not thousands of BPOs through the crash (broker price opinion, sort of like a non-official appraisal for bank foreclosure and other purposes) and really knows the value of adjustments and when to draw the "not comparable" line.

Down payments on commercial properties are bigger, particularly for smaller properties, and particularly for new investors.

As soon as one is late give them notice to non renew.

It's a non-starter for your Mexico place. 

Whatever that number is, ask for it in the form of non-refundable additional earnest money on the property in return for extending the contract.

As mentioned in another thread, the tenant is more likely to pay at the beginning of the lease and they'll likely still be living in the unit (and I have leverage to evict for non-payment) at the end.

Someone that travels for a living has no qualms about moving, particularly when running from an ex.
