This often only works with large properties where you are raising north of $1mm in equity, otherwise the legal fees eat up too much of the overall deal to make it worthwhile for anyone.  

In addition to above, consider utility entrances.

Selling your property now will incur commission fees, so you’ll take additional losses on the transaction.

The estimated cost to finish the basement is around $25,000, with an additional $24,000 needed to complete the rest of the property.

If the landlord was aware of his past, yet rented to him anyway - any lawyer worth their salt would make a nexus between those two pieces of information and create a liability claim.In addition to the extreme negative press you would get, it also takes time, money and energy to defend a lawsuit you will eventually win.

The first link to the property does not show the additional studio. 

Asking for additional credits could easily ruin this deal.

North Jersey is very town by town so tough to say more without additional details. 

You might consider Midtown and take Marta to work as Midtown has some additional opportunities for ownership and rental thereafter.
