He may have been having finance problems. Most of the time, these days, an "investment firm" buying it means, "1-800-we-pay-cash". They prey on peole, buying at a substantial discount off the homes value. But, it IS quick cash!
If he was on a spiral, the home going, and then burning, too, was probaly a good reaon to escape for a little while (to him)! Imagine how he feels after being fired!
LOL! I have no idea. It's such a strange story.
