While a cash-out refinance may have seasoning periods, some home equity lines of credit do not and are usually (not in all cases) available for down-payment capital just like cash. 

As for timing, consider that pre-approval to the closing period is around 45 to 60 days.

@Ian Walsh said it best, it is definitely like marriage, at least for the hold period that is!

@Brandon Fuhrman I’m sure some of the others will chime in but it would seem to me that the smartest thing would be to keep that account open and use it periodically and pay it off, improving your credit, and get the bank to open the correct business credit card for you.

As an investor, I start with, 'Does the rental income cover the mortgage payment, property tax and a little bit left over for maintenance, grass cutting, and vacancy periods?'

I don't care who they have over there as long as they pay the rent on time and take care of the property.Imagine your bank harassing you because you allowed a family member or friend to stay with you for a period of time....or even move in with you.Pick and choose your battles, but if you want to die on that hill then go ahead. 

This is the REVERSE of standard SFR and small multi-family (up to 50 units or so) management, where all funds stay in the PMC's bank account and are sent to the owner periodically, typically monthly.For larger apartment buildings iIt's normal for all rents to be deposited to the owner's bank account and the PMC be given access to this account to pay bills.Regarding your setup, it seems odd for only 8 units. 

Set a message for a couple of days after checkout as a reminder and then one the day before the 2 week review period is up. 

The woman who snapped doesn’t want to sell, expect for a brief period where she wanted 60k from the other for her share.

What I dont know is whether I can use it as a STR after the one year period.
