Is he managing, leasing out your units, collecting rent and security deposits etc…?

@Tim Monistere the tools that @Joshua McMillion mentioned are great tools to use plus I'd add to that list by using zillow rentals, apartments.com, Facebook marketplace, and see what the exact match apartments typically go for.Also take into consideration the type of finishes or other items you include with your unit.

@David ShivesI would have a separate checking account for the property where rent is deposited and expenses are paid out of and then a savings account or money market account where you can keep reserves.

Some say if they have a security deposit and you know they will be difficult promise a full refund as soon as they move out and turn over the keys. 

I assume you kept her security deposit.

Are there statements or bank account deposits that verify they are actually paying rent?

Sine her rent is unpaid, there is not enough security deposit to cover both unpaid rent AND damages that may need repair.

I get loans from a local bank who takes application deposit which are refunded if no loan is closed, less the cost of a credit report or possible appraisal.they offered true no credit reported commercial loans that don’t count towards your Fnma list and have long before the new lenders.

I don't mind leaving capital in a BRRRR deal provided there is equal or better equity to match BUT it also has to cash flow to my standards while fully leveraged at 75% of the ARV.
