Yes - give them 1 week to accept it and move out with X amount of days.

Move on and cancel this week before due diligence ends.

@Winn Vu If she signed for it, maybe she lost it in the process of moving.

I'm primarily looking at SFH that are move-in ready, mostly Class C, $110,000 to $160,000 and making an offer soon. 

If you're running a tight ship, you can expect to drop 10,000+ letters before you get a deal, and then you should average 3,000-4,000 letters per deal moving forward after that. 

I moved to Columbus a few years ago (from Portland, Oregon which was super expensive) to become a full time real estate investor, and ever since, I've completed quite a lot of BRRRRs, flips, and own a successful rental portfolio here in Columbus Ohio. 

Yeah I think a HML like @Logan Singleton mentioned would be a good move to call around or connect with a loan officer like him perhaps to see who would fund those type of numbers, but if you wanted to explore private money there's 100 ways to structure the deal.

She would need to move out of the property to be eligible to refi into a DSCR/hard money/private money what ever you want to call.  

Starting out with a SFH or duplex is great because you won't have as many moving parts.

If the system is not user friendly, people will move to simpler softwares.
