Maybe in a larger urban area. Here, most lending is still local banks and mortgage companies. While some things may exchange info online, many banks have their own closings in the bank or at the title company in person. If a buyer is out of state, then perhaps online via the title company. I am involved in a closing now, and like the last one I did, we will close at a title company office.
As for Mercury, I've yet to encounter a bank who uses them here. And probably the most popular platform the small and regional banks here use are bid systems like Exact (Rims). BTW, you can sign up with RIMS. I think they charge by the number of counties you cover. That was an issue for me since I live near the corner of 4 counties- 2 in each of 2 states.
Exactly. You might even try to get on a bank as an appraiser-reviewer, even ordering appraisals. Get your RE license - usually is cheap, or, apply to the title company doing title work. Title work background was really useful back when I started, and we had to actually go to the courthouse to get tax cards and data on sales. You need work and think in terms of a long-term planning of a career.
Other areas I would think about is appraising things besides real estate and you might also try applying to regional insurance offices as an underwriter or adjuster. And there are independent adjusters who sub out during storm events. Speaking of which another source of income is to apply as a contractor for FEMA. We've had several former forumites who did FEMA work. It can be tough, Katrina was a nightmare situation but FEMA sent dozens of contractors there.
