Such a good read Michael.My wife and I moved from the London, UK to America almost 4 years ago, we started house-hacking in 2016 and saw that our accounts just kept growing💰💰💰😃. 

I am originally from the UK, however I currently work in the Commercial Real Estate world here in Orange County, California but am looking to invest in residential SFH in middle TN.

They may have nice appreciation but that's a bit of a gamble.

===================House prices in parts of London that were once at the epicentre of the UK property boom have fallen as much as 15% over the past year in fresh evidence of the impact of the EU referendum.Figures from Your Move, one of the UK’s biggest estate agency chains, reveal that the average home in Wandsworth – which includes much of Clapham, Balham and Putney – fell by more than £100,000 in value over the last 12 months.

It would be better to pay whatever it is for testing soil out of pocket before closing and lose the money if tanks leaking then to buy the house as a gamble and have to re-mediate afterwards.

Buying in a hot market with the hope that it appreciates is essentially a gamble. 

. :) however my gut feeling - without complete understanding of their risks, structure, leverage, performance in a bad market it is quite a gamble for NPN...

I have lived and invested in the US and now I am partially based in the UK. 

@Bonnie Rhodes I started investing in lemonade stands when I was 9.Then I flipped marijuana in Middle School and ran illegal gambling in the high school bathrooms.

However, if you want to stay in SFR's I would suggest working with someone who can locate deep discounted properties and give you some equity going in so you are not gambling on appreciation kicking in.
