I believe property tax rate is a bit less in OC. Sales tax generally lower too (varies from city to city in both counties) but if you live near the county border you may end up making a lot of purchases in the other county, regardless. More on reddit.com

As has been mentioned elsewhere, tax deed properties can be complicated and will vary from state to state. Typically, the taxing authority/municipality follows it's laws, files a lien against the property for taxes owed, and will generally take rights to deed on the property. Make sure you understand the differences between a "tax lien" and a "tax deed" sale. At auction, you will typically pay, and take possession of the property via a quit claim or property transfer affidavit, usually within 24-48 hours. You may, or may not have specific restrictions as to access, personal contents, or people still actually at the property. You also may, or may have assumed specific issues with the property. This will give you rights to the deed, but, this does not guarantee that there may not also be competing claims on the property. You will want to consult with a real estate lawyer that is fluent in this type of transaction, in your municipality, county, or state, and will probably need to initiate an action of quiet title. Just because you have rights to the deed, this does not give you a "clean" title to the property. A quit claim deed is not a warranty deed. At a minimum, you will want to go through the quiet title action, and engage with a title company to get to a warranty deed before doing anything to the property other than cleaning and securing it. The last thing you want to do is to spend money on a remodel or on development work, only to find out that the property title has some skeletons in the closet. You will also not be able to use the property as loan collateral or sell it if you do not have a warranty deed on it as that would be considered a non-insurable action for title insurance. Also, depending on the property and your usage (I tend towards commercial/industrial) you will want to get an ALTA survey (or boundaries at least), a Phase I survey, and potentially a geotechnical evaluation. I had a friend that purchased a residential parcel on tax auction, only to find out that a prior owner had been disposing of his used motor oil in the back (for decades). Some other considerations; go to your local municipality and get any history of ordinance violations that the property may have. Check on the zoning (again, I know someone that purchased a residential home to rent/flip, only to find out that the underlying zoning was industrial and that the change in ownership un-grandfathered it's use as residential). Check on any permits pulled for the property; indications of unpermitted work done can be an issue. More on reddit.com
