Some areas may have an office specifically devoted to tax sale. 

@Alex Ng Because I have worked with my contractor for about 20 years now in some form or fashion( he started out shoveling my roof), he usually walks all of the properties I look at on my initial visits and gives me a rough estimate on cost of rehab and a time frame for completion based on his current schedule and how much time he has to devote to the project.

I do this part time, but hope to grow my business and eventually invest full time, or at least much more time than I'm able to devote now (I'm a mechanical engineer by day).

I have a niche area of commercial that I would rather devote that time to and even that has gotten hyper competitive.  

I'm working tirelessly to get my first syndication deal completed and under my belt, and I've devoted countless hours to prepare myself to be able to get this done.

So be prepared to devote the time needed to go through it all. 

Best left to people that have the time to devote to manage a team at a distance. 

I have great piece of mind knowing the rentals are being managed well and I have the time to devote to other projects.

I devoted all my time to finding a private lender and presenting a great deal.

Overall it was successful and would have been more so if I'd had more time to devote to it - I ended up selling because it wasn't quite worth the stress to me not living close enough and working full time and with the market going wild it made more sense for me to sell last fall.
