Otherwise, you're asking me to trust someone's personal math more than an actual calculator.

Michael,It is true medium term rentals do offer a higher per month rental income than an annual unfurnished rental.

Generally duplex triplex or quad will have better cashflow than an SFR or a Condo so be open to that as wellLook at numbers on 100 PropertiesMake offers (below asking price) on 10Somewhere between 1-3 will be accepted

If you like property from a buy & hold perspective, I'd encourage you to completely exhaust your refi options prior to exiting.  

I had a bunch of law students and they always had money to pay, but were so exhausted that they'd forget to give me a check. 

I'm exhausted :-)

A guarantor simply guarantees payment, nothing more and before any guarantee might be enforced the vendor must exhaust all prudent collection efforts from the maker of that obligation before making demands.  

Med students are supposed to be great, like law students, because they're too exhausted to party. 

All they do is study and they're too exhausted to party, and spend most of their time at the law library. 

You'd tell them to tell these people AirBNB is a lot cheaper than an Extended Stay Hotel, and if they want an even cheaper deal, they can call the local hostels.Don't be conned by these con artists.
