I saw once where a developer gave the buyer a pass on paying HOA fees till a house was built on a lot. 

California law requires abandoned tenant property under certain circumstances to be sold at public auction.

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!

Quote from @William Dorrough: I currently either purchase and value add large scale multifamily properties or develop, and build ground up my issue with scaling is we have done this without brining in investors i have a great deal flow with a good track record im really looking to do more i have the capacity but have the need for more capital in one way or another  Scaling without investors can be tough, especially in multifamily.

If so what were the circumstances and what was the reasoning?

funding land flippers as a capital partner is my latest thing.. since finding lenders for land is very difficult. continue to fund small developers soft costs for % ownership.and continue to be capital partner for flippers and BRRR folks

This sounds like a development, so you and your team should have years of experience and a track record of success before you take other peoples money.
