I am a mobile home installer in Florida. We contract directly with the homeowner to install the home and hook up utilities. I supply and pay subs to complete the electrical, plumbing and HVAC. I would like to know what happens in the event of non-payment and I have not sent an NTO. I would also like to know what I can do if the homeowner requires a lien waiver. I am unwilling to sign a lien waiver, it is sometimes my last hope to collect in the mobile home industry.
