I'm a licensed commercial and residential agent and looking to acquire 28 units though owner financing. someone knocked it out of the park when they said your return is theoretically higher if you use financing vs cash.

I highly recommend against this tactic as you are going to swing a bat at a hornets nest or worse, knocking on their door.

Since this is minimal service, to minimize your hourly payroll time, you could consider a solution like ZenDesk for client question intake, and have a VA respond as appropriate and escalate to a licensed agent, though this will have the knock on effect of requiring more systems or contributing to lower client satisfaction when they can't reach an agent. 

As an LP I was invested in a deal that had a fire knock out one of the buildings.

Had 4 people randomly knock within the first 3 days.

Purchase price: $40,000 Cash invested: $60,000 We rehabbed a Historic home that was sold to us by a neighbor knocking on the door.

Last year we saved even more because one property got $120,000 knocked off by itself because someone just made up a # to put on it.

Honestly, as sexy as it sounds to be active and go after them on your own, as a rookie, even with some book education, the real world can knock you on your azz so I would suggest going with a very experienced and proven sponsor.

Or if you're willing to hustle, you can try door-knocking and driving around and looking for FSBOs. 

Would knock the price down significantly of cars, parts and service.
