Over my past 25 retail sales, I've averaged nearly $25K in profit, so being conservative is working.I've hit $40K+ profit on two projects ($145K and $165K resales), I've hit $30-40K profit on 6 projects (resales from $95-175K), and have only come in less than $15K on two projects (my very first flip was one of them).So, I really like the methodology of shooting for "singles" but being conservative enough that they often turn into doubles and triples (and maybe an occasional home-run, depending on how you define it).

I have used three different analysis methodologies for determining the right price to pay for this property.

The biggest lesson learned to date has been the standardization of the construction materials, quality and methodology.

I'm looking to make sure my methodology makes sense.

It's all in the math and valuation methodologies.
