This will start with a letter to all, stating the new ownership, any new or newly enforced rules(no smoking, cleaning up after dogs, etc.), and mentioning that they have until a certain day to start paying the rent or move on.

As an engaged seller, I just called their loan officer whose letter head the approval letter was on.

If that is a LOW number (perhaps single digits), then that would be a signal that you have some built up equity to either cash out refi or do a 1031.

You should get pre approved before buying anything.Most sellers, if not all, will want a pre approval letter or proof of funds with the offer.

They will probably give a loan letter that states their average time to close your type of loan and the maximum amount you qualified for.  

And I am actually going counties for the owner occupied haha, Im going as big as I can within reason and my ability to handle the letters. 

.- 20y fixed- 5.5%- commitment fee - $1,000 - "due upon acceptance of the commitment letter" + $250 docs fee.

As I see it, your options are a warning letter/discussion, a 3-day to perform or quit (regarding quiet enjoyment of premises), a 3-day to pay when the rent is due (but I stress again constantly collecting on the 10th has tacitly made the due date the 10th unless you reset with a change of terms), or flat out termination with a notice to quit (30 days if living there for under 2 years, 60 day for 2+ years, or 90 day for a HUD tenant or as your housing authority requires).

I am about to start sending 5,000 letters/month.

Does anyone have a letter that they are using to market to out of state owners of properties.
