We don't have to call it climate change, but environmental risk factors or severe weather impacts the costs of real estate investment.

Even if we had the money there would be politicians and labor unions to deal with ( and maybe pay off ) environmental reviews , homeowners groups , lawsuits etc .Low barrier to entry and low price doesn’t necessarily mean low risk though as we’ve seen from those that have lost money with certain turnkey providers that promised real estate as a low / no risk “hands off “ way to create passive income and wealth .I agree also that a lot transfers and you often hear people on BP podcast and other places say things like “We aren’t in the real estate business we are in the marketing business “ especially if they are wholesaling for example .

You would also have to pay for an environmental inspection / building inspection.

Tax sales are a way for a SELLER to get rid of a property that they can't sell otherwise; like toxic waste sites, mold problem, hazardous material problem, environmental problem, failed septic, failed well, encroachment, title flaw/defect, IRS problem.

Environmental laws are a nightmare in Massachusetts.

(*Note: we waver on the slightly neurotic side when it comes to environmental health - I'm sure most people would be totally fine living in this county, plus our soil tests showed totally normal levels of heavy metal exposure.  

Ranch land, farm land, land with preservation easements or environmental easements, land for wildlife, water, air, mineral rights of land, land for development and subdivision, and general land use of all kinds.

@Sonia Spangenberg If the city is giving you issues, you could ask them if you gave them an environmental report showing that the land is safe and added septics is doable and won't harm the water table that might get them to calm down. 

If they choose to stay from here, they can no longer retaliate with hazardous environmental claims.At the same time, advise them that you will be inspecting and retest for radon so you can verify hazardous environment.

Everything from zoning to environmental studies to utilities to soil tests to water management to permitting, etc.
