It takes 45 days or more to close with a 203(k) due to all the red tape and contractors and our seller kept threatening to back out of the deal and demanding extra money every time it delayed but we eventually did close and it was worth it. 

We have started threatening to send to collections during occupancy if unpaid by X date and have had success in receiving the payment.I don't think an increase as you suggest would fly. 

After she threatened and screamed at my cleaners I threatened to call the cops, jack the rent, and do all could to make them miserable.

Even with the note being paid though, the banks will still send threatening letters.

The attorney who drew up the contract said he would write them a threatening letter for 300.00 asking for the proof of insurance, but if they continue to ignore the request I will be out even more legal fees. 

I see these as symptoms of a potentially overheated or bubble-threatened market, and they are not hard to see if you pay attention.

Upon starting the eviction process with that tenant (this is where the good lease comes in) the girlfriend started calling and leaving threatening messages on my voicemail.

(their relatives threatened to stab each other during one fight).

Anyone will just laugh at at you if you threaten them with any action.  

I think he’s going to try to threaten us.
