Personally, I would make the decision on the long-term relationship, not a few hundred bucks in fees. 

I want to go with Corporate Rentals with like extended short term that are 30 days or longer with things like Nurses, FDIC Agents, Oil Workers, you know those people who have to go into a hotspot to make things right and get paid BIG BUCKS for what they do and pay for like 3 months at a time. 

125k to make a sleazy 900 bucks a month .

If they're on the Forum naming them would give them the opportunity to show their true colors.it would be common in the turnkey world if the TK operator said rent was and it was not.. they would reimburse this guy his 1200 bucks.. although you don't want to get all stressed out over 1200 dollars.. that's not enough money to really worry about..

Furthermore, the note states that A) his monthly payment to me should be $825/month and B) it is a balloon note payable in full at maturity (April 1, 2019).

Cut electrical wires in the breaker box mean big bucks during rehab.

If the glass and door trim on the medicine cabinet are in good shape then just sand and repaint the interior to save a few bucks.

You’ll be making around 100 bucks a door when it’s said and done .

They're not trying to make a quick/big buck off the first (and only) loan you do with them. 

your projecting best case.I would take 60% of gross for back of napkin and if it still works then do a deeper dive.those type of C class properties are going to have lots of turnover.. and your probably not going to turn a unit for 300 bucks.
