Last summer a contractor that was building us two pergolas and grilling stations had to take $3K off his bill because he passed the deadline he agreed was easily achievable.As for how to deal with your current situation, prodding is about all you've got.

Thanks Bill, any idea how to determine depreciation capture?

How about a credit against their final month’s rent, assuming all payments are made on time?

To figure out the add-on to the rent, I took the largest bill and split it according to square footage.

They will use the dentist but probably only every 6 months.

You’re afraid of losing money month to month.

Typically, you can only do one rollover per 12-month period (again, IRS Publication 969 has the details).In the end, having the option to invest your HSA funds is usually a better bet than letting them sit in a basic savings account.

After months of poor response, I emailed my representative that I was terminating their contract per the contract. 

If you were not collecting and remitting in the past, you should hope TX Dept of Revenue is not as good as they are here in FL because they will be sending you a bill otherwise.

If you're looking for cashflow, you may have to consider 3+ unit properties, as traditional 2 families don't seem to fit the bill anymore.Happy to connect and chat a bit more about your goals.
