Environmental could be a substantial issue.

They'll likely have different sets of codes/standards for building, electrical, environmental, etc.

Investing in eco-friendly properties can attract environmentally-conscious tenants, contributing to long-term occupancy and positive public perception.In conclusion, the tiny home movement isn't just a passing trend; it's a smart investment opportunity that benefits both buyers and real estate investors.

From a non-financial perspective, I am not loving the property management aspect of the home as it is not in a great neighborhood and even as the best AirBnb host ever, there are environmental factors that I can't control.

My question regarding the clear title has to do with the liens exceptions list from auction.com They have this list:"Most liens are removed after a foreclosure property sale, but certain liens may remain.Here are some examples:Any lien recorded on title prior in time to the foreclosing mortgage.First Mortgage (if the foreclosing mortgage is a second or third mortgage)HOA or COA assessment liens (in certain states)Mechanic’s Liens (in some states)Government liens such as state and federal tax liens, city or county liens, US Government liens.IRS liens (IRS may buy the property within 120 days after sale at the price paid at foreclosure sale)Code Enforcement Liens, Environmental Liens, and Utility LiensChild Support Liens"Were you then able to get the title company to give you a title insurance with a title policy that covers these liens exceptions.

Check for any potential zoning or environmental issues that might affect future plans.

One, actually builds environmentally friendly homes (to include SIPs) here and there, but mainly focuses on the drawings these days.

For new investors looking to make a splash in the real estate industry, especially in the younger newcomers from what I have seen, delving into the realm of tiny homes presents a unique chance to combine innovation, affordability, and environmental consciousness all while documenting the process to share across their own social media accounts collecting thousands of followers and views that on their own become yet another source of income. 

Do your own due diligence.The first thing you need after you are getting serious about this property is a Phase 1 Environmental Study.  

The DD process includes, but is not limited to, having a soils engineer prepare a soils analysis, an environmental engineer prepare a Phase 1 environmental report, market studies, title review, legal review, and zoning review.
