With that being said, as many people have stated, the information they are selling needs to be of value, and not just to "up sell" you to something else.I'd gladly pay (and have paid for various trainings/seminars), because the information is: professionally organized, informative, niche specific and easily digestible with books and/or emails with links to the information that was discussed, as well as with ways to utilize the information received, because it's all for naught if you don't actually do something.

RichGot it.I normally deliver everything new top to bottom including re-texturing the walls - when you walk in it is looks like a brand new tract home.

The large tract builders average $140 per square foot.

I watched a 15 acre tract get bid up to full market price. 

@Chris Garzino  Start by digesting all of the free resources.  1.

Realistically it's more like $275-350/ft2 these days for an average home, and even the tract shacks are costing $250/ft2. 

I would suggest that those buyers that want a 2.5 acre waterfront estate want to be surrounded by those types of properties, not tract homes on .65 acres.Have you considered partnering with a builder to develop out the four lots?

You need to consider that using Baltimore neighborhood boundaries or census tract data you will likely be looking at an average of both good and bad areas.

Proximity to the Heights as well as Oak Forest is desirable and there's lots of variety in land such as single family, larger tracts of land etc.

I'm going to take the weekend to digest all this wonderful info from you and the other posters here, and I'll post again on Monday.
