If the tenant does have legitimate complaints about the landlord failing to maintain the property as required by law, their remedy is to escrow deposit their rent payments with the court.

Despite his outside employment, he maintained that he was a real estate professional who spent more than 50% of his time and more than 750 hours on real estate activities.

You are right most leveraged ETFs have daily rebalances to maintain equal leverage over the intended investment time-frame, but that doesn't really have any effect on what the value of the ETF is, it's simply adding exposure (or debt) when NAV increases and reducing exposure when it decreases.

They didn't buy your property, they are just renting it, and yes, you want them to maintain it in good order, it's not their responsibility to improve on the property.

I would probably take a different course of action, inquiring with counsel on vacating the original agreement to maintain the installment contract.
