There's a limit to how much repairs can cost vs. a complete raze and re-build(will check current regulations to see what they are).My only concern are the liens and the problems inside.

Everything costs more than you think it will.

@Nima MalboubiI personally think that the risk is relatively low with only four units.

But are just sitting on it as the development cost is too high.

Is there a loan that will include the purchase price and rehab cost?

Love Toledo we are easily getting properties there with great cash flow and low entry cost in great areas.

Also consider what your cost in time and money will be in trying to recover the money. 

Transaction costs of selling, then buying will mean a hit to the equity that you have, plus a likely tax hit.

If you win, they will have to pay the extra expense of the filing fees, etc, on top of what you say your damages are (which would be the cost to hire someone else to complete the job).
