That is what caused mortgage rates to plummet recently. 

I just hope the market doesn't plummet by the time they are done with the house in about a year or so. 

Suppose borrower does not lock because he emails me at 7 pm and I'm not at work.But tomorrow maybe rates get dramatically better because Russia invades Syria and the Dow Jones plummets and Trump actually got elected and everyone on Wall St gets scared and sells stocks to buy safe things like 10 year tnotes and... mortgage backed securities (this is why they are correlated). 

Going by history, either the price of silver is going to sky rocket, or the price of gold will plummet, possibly a mixture of the two.I also keep my precious metals here at my house protected by my .45.If you don't have it in your possession then it is pointless when/if the economy collapses. 

Now rates have plummeted quite a bit and I am thinking of asking my lender to provide me rate lock float down option.

Welcome, no experience in real estate in Spain for me, hopefully will live somewhere on the Canary Islands in the future :) , few years ago prices plummeted in some regions but they seem to be more or less stable now.

They cant value my house where it currently is because the value of my home has plummeted 57% over the last 2 years.

If values plummet, people still need housing and it opens the door for great investment opportunities.
