I could go on.Case in point -- there's a LOVELY house in my area, on the water, good size, 1/2 acre backyard, great school, amazing neighborhood -- the house has everything going for it.

Rehab came out to be 33k due to the size (1700 sq ft. with 3 bathrooms) and a decent amount of drywall work.

You will likely qualify since you're serving.

I personally don't think there's a good one-size-fits-all answer for that (I think few here would claim there is).

So some things have changed at Listsource and they are not serving their customers well.

To determine the market resale value, utilize Craigslist, Land Watch, Land and Farm, EBay, Zillow, and/or any other other online resource to collect comps for vacant properties of similar size in nearby areas.

Access to each lot should be considered... is there road frontage for each and if not, then you may have to explore creating an easement(s).You can certainly get feedback here on BP, however, you may well be best served consulting with a local real estate attorney well versed in zoning matters in your area along with surveying/engineering folks.Good luck!
