Many states allow for an acceleration of a loan for mere re-vesting of title, while others may prevent it.

Is there anyway to prevent this from happening?

Toilets will need to be drained and then antifreeze put into the traps to prevent the remaining water from freezing.  

@Anita Fofiefor Calgary Alberta I would look at seller carry for the balance or a wrap around mortgage saleRead the HELOC and see if there is a provision in there that prevents a second mortgageYou could have a three year balloon that forces them to refinance@Roy N. is a pro in Canada You also could look at a lease purchase there they put down 10% and have a three lease along with a sale and purchase agreement spelling out the terms

No representations can be made on how any court in any state or federal, will interpret the regulations or apply them, and that said interpretation or application will be different from this analysis of the law.Therefore, there is no guarantee that relying on this analysis will prevent governmental or civil actions against the lender/seller.

Anchoring sills to foundation, securing your hot water heater, and securing any crib walls with plywood to prevent their collapse.  

A collection letter to the last known address of the borrower every few months can prevent such claims.

They want to prevent people from abusing these loans.

There are also 2 seller disclosures - a 2014 one where there was even more undisclosed data and the seller checked a box for, but did not disclose that there could be a condition, including but not limited to financial one, that may prevent the seller from completing the sale of the property. 

This prevents them from trying to squeeze your earnest money/escrow money by saying you violated the contract somehow.
