If they don't pay rent  by the 3 day notice deadline,  go to court to get the eviction- be aware it may take 2 hearings ( if the tenants show up and ask for more time for legal counsel).  

I sat next door to a landlord in court who was being forced to evict his tenant by the police - he was facing heavy fines if he did not evict his "drug dealing " tenants.

Maybe have the contractor include a simple declaration on the receipt that it's paid in full therefore the contractor will not place a lien. 

The level of liability protection can vary widely from state to state and even from one court to another.

I've talked with a receiver and he said that the lien could be waived if the receiver takes over and the courts rule in the city's favor.

Ernie resells court data and that will save you much time. 

They went to court and the contractor lost the case.

These lawyers will look up all the owners of a property and bring them all to court in hopes of getting money out of one of you.While lead free is the best to be, if you've always been lead safe, you should be fine.

I haven't seen a bank owned home yet that still has all of the former owners belongings in it, unless it was in probate due to a death and the courts were handling the sale.

I then went to court and completed the eviction.
