There has been a lot of talk about 401k and other savings instruments, all very good options.

Honestly, it'd be better off as a mini-series, and could get into the meat of the situation.Keep in mind they HAD to use clever tricks of explaining the features and nuances of the instruments being used for lay people.

The idea is a mortgage or deed of trust must actually secure a debt for the instrument to be enforced.  

I'd like to know which instrument to play, guitar, drums or piano?

The whole 3 to 6 month idea you explained seems to ignore earlier in the story when the security instrument was foreclosed so it does not exist any longer therefore no further delinquency or default can occur.

But the security instrument (mortgage or trust deed) has a life of it's own and lives on and isn't extinguished by SOL.

Can't really tell because you need to look at the source documents, instruments.

@Jim Witten, the 45 day form can be any instrument in writing between parties to the exchange.  

Look at the deed of trust (security instrument), you as trustor (property owner) grant a trustee (usually a title company) the power to sell your property to pay the beneficiary (lender) should you default. 

Be an owner occupant.4155.1 4.B.2.b FHA Requirement for Establishing Owner OccupancyAt least one borrower must occupy the property and sign the security instrument and the mortgage note in order for the property to be considered owner-occupied.
