We sell materials. Our customer was a sub of a developer that buys lots and builds spec homes that become homesteads to their buyers. Sub defaults. Job is in May. We send 2nd and 3rd month letters July 15. We file the lien affidavit September 15 (no mention of homestead). We learn the developer sold the house in August before our lien affidavit was filed in September. Can we enforce the lien? If so, who are the proper defendants? If not, would it matter if the August sale wasn't reflected in the online property records when we filed our lien in September? What is our best strategy to collect?
