Doing so, however; does make it a brand new offer and not in force until all parties come to a meeting of the minds and sign the final counter and original contract.In this case you can counter a realistic time frame in which they must release the "subject to" clause, giving them time to get their appraisal in and or make a decision to continue with your purchase knowing their deal is pretty solid.

Once they are comfortable, they release the security deposit to the owner so that he or she can make up the repair costs. 

Then when we sell, we pay him and he releases the lien.  

If I come across anyone, I'll let you know.I've had some success using the arrest records and targeting ages over 50. it's funny, Johnson County is completely comfortable with releasing this type of information with addresses included, but tax delinquency and code violation is completely forbidden. 

There are different ways to handle it from there, but all options basically involve you releasing the option for a fee so that the buyer can buy the property from the seller.

But once the tenant paid up, the landlord dropped the case leaving me with this mess and asked to release the remaining balance from the escrow which to his surprise the escrow refused, haha.  

Once I sell 3 more properties the loan will be paid off and that'll be a day to celebrate.

Seller wont sign mutual release claiming they were not given time to remedy damages. 

Perhaps you could have/still can find a third-party (escrow agent of some sort) to hold the future rent in an escrow account that would be released to you on a monthly basis?
