We have a house on a well.

Well, guess who IS green today?

(The "Morby Method") It's cheaper and faster and less painful to just to take a mallet and slam it into your knuckles and call it good.The biggest threat on a SubTo is missing payments.

Its a 100 year old house as well and not insulated the best.

It's compliance, inspections, fines, and threats by the government. 

It worked out well for me.  

Appreciation is limited as it is imploding demographically.Countries like Canada, Australia, NZ are well positioned for long term demographic and economic growth, but they are not as affordable as growing US cities like Charlotte, Atlanta, and Indianapolis at the moment.

I would also recommend getting a property manager as well in the future.

It was known, well known, back then what a significant threat the Soviets posed.

That being said if you need 20 different LLCs to sleep well at night then do it if you can afford it, but look at the really big players.
