Get your TM30 from your landlord then around the 90th day of your DTV stay you go to Immigration with your passport and TM30 for your 90 day report (complete a TM47 form). It is free.
Why did you get problems with a 30 day extension? When you get your entry stamp the 30 day extension is virtually a given, very unusual even to be questioned.
Your plan will work with your onward ticket and you should have no Immigration issues unless you have a recent history of Visa Exempt entries especially if you took the 30 day extension.
