Three months and a judgment against the property due to its condition later (and us threatening to walk away from the property) we were finally able to close - just one day prior to the county inspector doing a walk through to determine if the property is salvageable or must be condemned.

I mentioned before that N/Ps are sensitive to their turf, don't duplicate services or you can gain an enemy instead of a supporter, stealing their clients threatens their funding and purpose so tread carefully.This is the first hurdle getting into this niche area, after identifying those to be served and your mission, you need to know the other service providers and develop a working arrangement.After the ducks are in a row, you need to address financing.
