I provided all info by the deadline I was given.

I have a vision of building and developing mobile home communities in upstate NY that are vertically integrated to allow future members to choose from a catalog of homes, have them installed, provide them with financing options, and make the process of selecting, buying, and living in the community very smooth.Since this is my first time doing this, I would love to chat with an experienced mobile home developer on the following items:Zoning - navigating the zoning process to allow the community to be allowedStart up costs - I am a finance person who would love to better understand start up costs - septic / electrical / water / pads / roads / etcOn Going Maint Costs - in building our business case, I want to build a conservative financial model to capture all re-occurring expenses - utilities, landscaping, capex, septic clean out, etc.I know this is a lot, but would greatly appreciate talking to someone who is an expert in this asset class!

Have also used list source and prop stream before but the data they provide is very similar to what I pull off the tax records through CRS Tax. 

Sharing your goals can help others provide more specific advice! 

We have had one attorney contact us about one of their clients saying they never completed the form - we sent them the information and they asked us for all this other information which we ignored as we had no obligation to provide any information to them.

I furnish and provide amenities that warrants this so I do a lot of work to find comps in this particular space.  

Quote from @Steve Lehman: @Jackie LiuFirst and foremost the information that everyone has provided has been great.
