There's way too much to breakdown here, but a brief synopsis; essentially the work will include, fixing old pavement, changing full concrete medians to include trees, redoing powerlines that awfully crisscross and look cluttered, adding more sidewalks, better lighting, and general cleaning up the appearance.

*  When you get licensed, everyone (including BP) will try to sell you leads, signs, more leads, business cards, more leads, name tags, more leads, health insurance, leads, print/mail services, leads. 

I always tell them that I am required to follow a process which includes an application, credit and background check.

If they also do real estate sales, I would compare it to being a listing agent where an incoming offer will include proof of funds which could be a bank statement and private information.

Most of the insurance, exterior maintenance, water/sewer, cable/wifi, furniture, smallware, included.

Checking a few competing sources on a daily basis including the MLS.2.

They're likely trying to fix this by asking for a statement on your 401k so they can include it in your file, and make the investor happy... likely it was a reserves piece that was overlooked, a typo, who knows.

This includes a real estate agent experienced in fix and flips, several reliable contractors (since they can sometimes be overbooked or unreliable), and a real estate attorney.

Should I seek an agent who is available early in the morning, late at night, weekends included?

There are definitely lenders out there (my company included) that will refinance with no wait period (seasoning) if rehab has been completed.
