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.  

The HVAC company I called for an annual maintenance visit said there is nothing to maintain.

@Kris McfarlaneHow much have you been able to rent an upstairs and downstairs to maintain positive cash flow?

you can get a decent sized shower in there and still maintain an 11x11 bedroom. 

There are lots of reasons for this: no down payment; no job history; unstable employment situation (frequent transfers, for example); does not want to maintain/rehab a home; wants to live in a nicer area than buying would allow; ETC.We have some older women who could afford to buy, but like being able to just call us if something goes wrong rather than hunt down their own repairman and pay the bill out of their pocket.

There are also very large transaction costs on both sides of the purchase (explicitly or implicitly) and large organizations with political ties to maintain the cartel for real estate commissions.  

I've submitted an inquiry twice and both times the response came that it's tenant's responsibility to maintain the yard and thus trim all trees on the property.I would never think to try putting trimming big trees on my tenants for a number of common sense reasons, but this landlord is of a different opinion.

My mother-in-law is now having to take care of everything (mowing in Texas heat, etc) so it would be nice if the solution would downsize their living space (already pretty small at about 1400 square feet) as well as removed the need to maintain the lawn, etc.
