And the "remediation work"?  

Scott, other cases have expanded the remedies of defaulting vendees to include even willfully defaulting persons, which has effectively taken away the automatic power of sale.

It sounds like you have a good handle on the remedy that is needed.

It's very possible with $20k but I think its risky.. yes you can use FHA and leverage 30x buying power but things can be great and also go sideways.. it can easily cost $20k to remedy an issue.. education definitely helps you get there with the least path of resistance 

It is very high, remediation is suggested above 4 pCi/l.

I hope things turn out well for you and you at least make $5,000 in profit from the flip.The problem with major structural problems is that when you sell it, the next potential buyer who previews your property will think "this structure has had structural issues, and it has been fixed. however, there is a similar equivalent property nearby selling for the same $145,000, and it has never had major structural issues that needed to be remedied. why should i buy yours?".

Make sure you remedy any soft spots.

To add, the remediation has been completed and confirmed no mold is left in the unit and money off rent has been given. 

Any parcel of real property for which there shall be no other purchases will be struck off to the municipality in fee for the redemption at 18% and the municipality shall have the same remedies and rights as other purchasers, including the right to bar or foreclose the right of redemption.
