My primary focus is on the BRRR method, with a greater emphasis on appreciation over cash flow.For those with experience investing in Cleveland, I’d greatly appreciate any insights on neighborhoods worth focusing on.

This depends on if you are using the Cash or Accrual method of accounting for tax purposes.

I'd send out 500 at a time, using a different mailer/method weekly.

Sure, I could look for a higher paying job, but I was wondering if anyone has any creative short-term methods to improve my ratio.

I will be moving to Austin myself in two years, since Austin market is quite dried up, thinking of investing in SA as OOS.

But why would that make them want to use this financing method?

There are several different methods you can use.

I have heard that it is common practice that private money lenders collect a monthly fee thru various methods, I'm trying to determine what those methods are.   

It will be a little trying for 6 units to use - they're slower because they do both washing & drying - but that would be way better than expecting tenants to drag wet laundry around.

My experience with friends/some clients is get their numbers via whatever method you can and reach out via the phone.
