Getting title and getting clean title for properties bought at tax auctions are two different things. 

OP said: It’s frustrating, especially because our due diligence came back clean, leases were solid, and the property had just been fully renovated.

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!

Build a local team for cleaning and repairs to streamline operations.

Contract is very clearly and states that if seller cannot produce a clean title than EM is to be returned to the buyer.

That teaches the occupants that they aren't 100% responsible for cleaning up after themselves.

So I offered to pay for the flight, if they returned a clean and empty house.

@Jason Tucker  you need to add in your utilities, common area cleaning, and turnover costs to determine if it makes sense. 

I also find that depending on the tenant, my one Airbnb property has less wear and tear because it's constantly cleaned and maintained versus my other rentals where the families living there settle in and accumulate stuff - which makes it hard to deep clean regularly (to my liking) as well as just the constant daily wear and tear from kids etc. 

You hired cleaners to clean the unit between tenants?
