The auction will wipe out most liens, except taxes, HOA's and code violations.

I would look at the 90037 zip code which is the closest to USC.

I worry about code violations and other issues.  

If it cannot be repaired as told by multiple trusted asphalt driveway installers I strongly suggest ripping it out and installing a new one that is up to local code and ordinances.

I got a promotional code #BuildiumRP02 that is good for 2 free months for every 1 year you pay in advance.  

Its what I learned in Miami Dade codes and it only costs maybe 20-30 bucks extra per roof.

As I mentioned above I thought the IRS code allowed for each parent to give but I am not 100% certain on that provision.  

@Lauren C. this will depend on local codes.

I appreciate any advices and tips from those that have had purchased tax lien from this area in the past, Don't know if it matters, but the properties that I am interested in are in the area around the zip code of 0613, 0615 and 06114. if you can also refer me to broker and lawyers that deal with tax liens in Hartford, CT then it will be greatly appreciated as well.Thanks in advance for your help.

What kind of radius do you find you are comfortable with for investment decisions (ie county, zip code, city, etc.)?
