Where specifically do contractors go to file a mechanics lien?

Below are a few comments on the mechanics of the model in general (not on anything specific to this deal).

Or if you know of a mechanic .Don't know the law's in Texas but here in California you can put a lien on it through the DMV and since it's on your property, the DMV will send out a notice to the owner.

Make sure to get your own inspection and have them check the big stuff like the foundation, mechanicals, electrical. 

I have undergraduate degrees in Mechanical Engineering, Manufacturing Engineering, Technical Management and a Graduate Certificate in Program Management and a Masters in Organizational leadership.

I am in my late 20s and a Mechanical Engineer by Degree and I work in project management/construction.I have been maintaining a high saving rate and nearing a Coast FI number to where I could start dialing back my work hours.Before I make any moves I would like to have some run time with a viable side hustle or part time job that I could leverage my degree and experience to still earn a decent hourly rate (or equivalent).Does anyone have any advice or any experience with effective side hustles or types part time jobs that I might be able to transition to?

Instead the city elected to hire attorneys from Irvine to represent the city in an attempt to seize control of the properties through a legal mechanism called "receivership," or have our buyer enter into an agreement with the city to completely rehab these dilapidated properties, within 30 days, and to lose control of the properties if they fail to complete the total rehab within said 30 day period. 

The high ROI is very attractive and with them advertising these properties as turn key homes I assumed no major mechanicals would need to be changed for at least 3 years because I was told everything in the homes I was purchasing would be brand new. 

If it goes dark you need to make sure location is good.NN, 8.3 cap, 3 years left primary term is a loser to me.I have seen batteries plus, banks, dollar stores, etc. take over the rare pharmacy location that goes dark.Roof is flat and if A/C etc.is old to replace roof and mechanicals is tens of thousands of dollars or more.

Anyways, for 2013, if its less & I'm assuming it is, did he do a lot of updates on mechanicals, exteriors and such?
