The repository sales will be found with the tax claim bureau and will be those properties that have gone to auction but did not sell. 

Know of any meetings or auctions I could attend just to get immersed?  

Can anyone please suggest some online auction websites?

Can someone help me with how buying a property in Essex county auction works.

In each county, there are properties that were not sold at auction due to a variety of reasons.

in my opinion, you wouldn't be able to sell your home once a COT is issued, and you are forever barred , so how can one sell your home after it was sold at auction ?

I am here to learn about working with contractors, using tax strategies,  exploring property management, and using tax sales/auctions to secure good deals.

Some investment gems to look out for are SFR in multi-family zoning that you can later develop into more units, dilapidated properties (drive down E Main St. in El Cajon and run a route through the neighborhoods following that street), and while your out in El Cajon check out the foreclosure auction at the courthouse, I believe if you go to the third floor business office you will be able to check out upcoming properties.

If you are looking for quick short term gain I suggest going into flip project but for rental I would go to auction and find a good rehab sfh or duplex to rent.

Would the bank accept half of that at auction?
