I know of a developer in my area that just (in the middle of) purchased a large track of land to develop.

@Bryan Gonzalez Experience is a big factor as @Bob Green said. 

Hi BP,I wanted to see what other flippers/ developers thoughts were on this topic.When does it become OVER NEGOTIATING?

If you’re looking at a multi, factor in the increased expenses like lawn care and capex gets more complex because some capex items are one per unit and some are for the whole building.

Stanley's daughter came out with a new book this month updating the research -- I haven't read it yet.Stanley identified several factors that keep you rich or poor: where you live, how much you spend on the house you line in, how much you spend on luxuries, how much debt you pay interest on, but I believe his most important finding is that a much higher percentage of millionaire men than normal will report on a survey that their spouse is more frugal than they are.Getting rich turns out to be very much a team sport, specifically, a team of two.

and in your case, thats probably a partial factor for the lower price point.

It also appears you can purchase development credits to increase by 4 homes per credit.

Department of Housing and Urban Development (HUD), covers places of private accommodation related to housing.

Biggest X factor is when we did our walkthrough, we noticed basement ( unfinished) is totally flooded with sitting water ( too high to walk through) and it seems like the water has been sitting there for months.

Putting CF aside, at the end of 15 years the value of A will be ~$135k, a ~35% return on the $100k, but B will be worth ~$675k, ~175% return on your $100k.This doesn't even factor in depreciation or mortgage pay down.Let us know if you have more questions.
