He told me it should be $350 a window ($2800) but when he sent the official quote it was $3800.

Update 4I received my official general contracting license today! 

Not your tenant...... not her lease...... pets not allowed...... even for visitors....Make sure your lease has language about "guests"..... how long they can stay over etc.....these girlfriend/boyfriend "guests" quickly become tenants not on the lease....

In large part the sheriffs dept being under staffed. but now they have dedicated staff to handle all civil suits.You have to send out a notice to quit and after 7 days you can officially file an eviction.

I've had some discussions with companies that have standard 12-month language, and early termination requires an immediately due amount generally in the range of what they otherwise would've earned had the contract played to its end.

Does a simple heads up via email or call work or should I send them something more official?

Your lease will officially be over on [Date].

I was wondering if anyone of you would know how much a person has to owe for the city to actually put an official lien on the house?

If so, then they're officially qualified and approved; otherwise, not so much.

A contract that contains language contrary to what the law says is automatically void and unenforceable.
