Welcome to Akron. Ranchplexes are my favorite type of unit.
You definitely want that mold taken care of. I can't tell whether the floor is wet/moist or whether that coloration is just from the concrete they poured when the waterproofing system was installed. You might have a bad surprise behind those $10 drywall sheets.
$180 net seems low, and I reckon you'll encounter the real cost of property management going forward - service and call fees and additional payments for any and all repairs.
Get ready for the minute you have to replace a month-to-month tenant, because that, by itself, will destroy all of your profit. Not only do you lose a full month of rent, but that's going to be turnover time where the property manager gets to go into the unit and do their 'repairs' and charge the service and call fees.
I'm not a fan of gradually raising the rent either, since it doesn't seem like the property can support that strategy.
Anyway, I hope the deal goes well.
