There is another possibility that a third party known to the seller may intervene contesting the contract being predatory.

You can try and the worst thing you may here is "Go away".Some states consider intervening in pre-foreclosure to be predatory and have laws against it, but ASKING is not intervening.

Is everything they pay in the intervening period rent  (i.e. there is no portion accumulated towards purchase)?

@Paul Alberry I had a Tenant call a couple of months ago when she claimed another Tenant walked in on her using a key.I called his wife first to try and intervene because the Tenant said she was calling the cops.Then I installed new locks, placed the new keys in a coded lock box and charged $20/lock.

To me, this is an acceptable risk given the current cashflow from the property and the likely changes to interest rates over the intervening years. 

A smart government intervenes in the marketplace enough to ensure fair competition and access and keeping a reasonable balance at both ends and nothing more.

If you have "very little savings" and are struggling already to cover loans and notes that you have out.... and your family is concerned enough to "intervene".... you are not really in a position to "start your business", if, by that, you mean real estate investing.

I have already paid the final invoice to the contractor.And the rental unit is located in OH.Do you think I should intervene in order to calm down the situation?

I've had a mentally ill tenant and a few my clients have asked me to intervene with; my advice is manage to the lease.

@Mallikarjun Reddy PateelSomewhere the government doesn't intervene 😂
