@Jay Hinrichs might have some good input on this because he was right in the thick of things during that time. it took a while during the GFC but yes mortgages were modified by the millions. 

There isn't much need to modify unless you are targeting lower income areas or subsidized housing but even then I'd be careful.

And even after that date, schools will be closed through the summer, no large-scale sporting events/concerts/gatherings through November or December, and I don't think things will go back to normal at the end of June, there will just be a modified version of the stay at home order that starts to open up lower risk businesses and activities (that have large economic benefits) over time.I'm buckling up and focusing on cash reserves.

I just posted this on a similar post, but will modify it for your specific situation:Allow me to be a counter-narrative.

I think that maybe the metric could be modified a bit to make it applicable to the individual investor. 

Could also list the colors/finishes you have in mind, if any, or let me take a few stabs initially and modify from there. 

I can modify the percentages to 8% and 5% as suggested but I used the numbers that Brandon Turner uses in his YouTube video.
