So, I purchased several tax certificates in PG County MD last May and some didn't redeem by the 6 month deadline . A few properties are not worth foreclosing the certificate but a few are worth foreclosing.   My question is about if liens and 2022/2023 taxes which are now due come out of my bid amount or due I have to pay those out of pocket? 

 Bid amount $6700

Certificate for 2021/2022 taxes $1,741 (I Paid this at the sale to buy the Tax certificate)

Taxes due for 2022/2023 $1300

Code enforcement lien $1500 

So, do all those get deducted off my $6700 bid amount?  Are 2022/2023 taxes prorated and paid out of the bid amount? 

Thanks for any input.
