How does buying a tax delinquent property work?

[Kian Tajadod]

Hi,

I'm confused on how purchasing a tax delinquent property works. If the property is behind on its taxes but not going to auction, is the process deal making and purchasing the same as a regular deal (except having to pay off the taxes)? For example, I am in Houston, TX, I drove around looking for off market distressed properties. One of the ones I found has been tax delinquent since 2005, around $12k to date, but not going to auction. 

Would writing up a deal be like the regular?

Could I offer to pay the taxes plus cash for the deed?

Is there still a redemption period considering it wasn't at auction?

All help is greatly appreciated! Thank you!
