As Grant Cardone would tell you "massive action is required".

So know the law, Know your lease and underline it and give a copy back to them, With that said.Yes charge them the $50.00 late rent fee. and If they don't pay you tell them you'll file unlawful detainer eviction action for non-payment of rent , you have no guarantee how they will leave the apartment.

I think there is so much value in networking, reading, and just being willing to take action. 

I think you mean"get a Quit Claim Deed" from the previous owner, to eliminate redemption rights where they exist, not have them "sign the quiet title", which is not a thing that can be done....a quiet title action is a judicial process that eliminates All possible interest, not a "document".

Just don't fall prey to what many of us have done at first and not take the action as well.Here is to a great 2017!

Actions are better than words.

It starts with a clear vision of the life that you want which directly shapes the business you will need to build by taking massive action. 

Ultimately take action and be consistent!

@Ryan Money Congrats on moving from analysis to action!

Their failing to pay in full when their tax return came made me realize they are simply not going to catch up and led me to take legal action.
