“If I stop paying rent after he stop paying the mortgage, can he evict me ?”
Yes, the owner can evict you, but why would he? If he’s truly going to walk away from the house, why would he spend money to initiate an eviction process against you? He would be throwing good money after bad money.
However, keep in mind that the foreclosure process is taking approximately 8 months or longer. Therefore, if he’s a dirty landlord/owner and you stop paying rent, he may try to get you out of there and deceive another family by getting them in there and collecting rent from them until the Sheriff comes and puts them out on the street.
